Matcha & Chocolate Swirl Milk Bread + The Original Milk Bread + Other Variations

If there is one thing I love, it's chewy, dense, soft bread. Crusty works for me, but it just doesn't have that, let's say, oomph that chewy-soft bread has. When I eat baguettes, I usually just tunnel my way through the center and leave the crusts all lonesome on my barren plate. 

I've had my fair share of yeast ordeals, which you can read about here. I had to take a long break before dealing with yeast again; a person can only handle so many failures. I've over risen, over baked... I was just over it all! This? Well this is my yeasty salvation. I love this bread, so much so, that I've already made four loaves of the soft-chewy-dense deliciousness. It uses a special method called the 'Tangzhong' method which employs the use of a bread-water mixture that is cooked to 150 F, then mixed into the bread dough. It is simply amazing. It makes the bread stay soft for days on end and gives it the ultimate chewy-dense texture that I love so, so much.

If you're wondering what I'm referring to when I say soft-chewy-dense texture, just think of Hawaiian sweet bread. It has almost the same texture and is a bit sweet too. I made two version here, the original milk version and a green tea-chocolate swirl bread. 

Both were delicious and came out perfectly! I couldn't believe my eyes when I saw a golden, perfectly risen loaf come out of the oven - it was a serious celebration. Next time, for the green tea-chocolate loaf, I might add a bit more sugar and flavorings. Though you could taste the distinct chocolate and green tea flavors, I could have done with a stronger flavor. I think adding a bit more sugar would make the flavors stand out a bit more too, so if you intend on making this bread (which I highly recommend you do), you should up the sugar!

Matcha & Chocolate Swirl Bread

Yields: 1 9x5" loaf

Original recipe here.

2 1/2 cups bread flour, split

3 tbsn. + 2 tsp. sugar, split

1/2 tsp. salt, split

2 tsp. instant yeast, split

1 large egg

1/2 cup milk

120 g. tangzhong (about 1/2 of the mixture below)

3 tbsn. butter, cut into small pieces, at room temperature

1 tbsn. matcha powder

1/6 cup unsweetened cocoa powder

For the tangzhong:

1/3 cup bread flour

1 cup water

To make the tangzhong, mix the flour and water together and whisk until it is completely dissolved and there are no lumps. Pour into a small saucepan and heat over medium heat. Begin stirring constantly as the mixture heats up - it will begin to thicken. When the temperature of the mixture reaches 150 F, turn off the stove and remove it from the stove to let it cool. 

Grab two medium bowls and divide the flour, sugar, salt and yeast evenly among them. To one bowl add the matcha powder and to the other add the unsweetened cocoa powder and mix well. In a large liquid measuring cup, combine the milk, egg and tangzhong and mix very well. Add one of the dry ingredients to the bowl of a stand mixer and make a well in the center. Look at your wet ingredient mixture and look at the volume as indicated by the measuring cup, then pour exactly half of the mixture into the center of the well. Fit the mixer with the hook attachment and begin mixing on medium speed until the dough comes together, then add the butter in and continue kneading. Knead until the dough is smooth, not too sticky on the surface and elastic, about 18 - 20 minutes (but each mixer varies). When ready, you should be able to take a chunk of the dough and stretch it to a very thin membrane before if breaks. When it does break it should form a circle. Remove the dough from the mixer and knead into a ball. Take a large bowl, grease it with oil, then place the dough into the ball and cover with a wet towel. Let it proof in a warm place until it's doubled in size, about 40 minutes. With a clean mixer, repeat the process with the other dry and remaining wet ingredients. Place the dough into a greased bowl and let it proof in a warm place until it's doubled in size, about 40 minutes. 

Once the doughs have doubled in size, transfer the doughs to a clean surface. For each ball of dough, roll out each portion with a rolling pin into an oval shape. Take one end of the dough and fold it to meet the middle of the oval, then take the other end and fold it to meet the middle. Flip the doughs over with the folds facing down and flatten with a rolling pin. Roll out the doughs until they form thin rectangles - make sure they are about the same size. Place one rectangle on top of the other and begin rolling up the dough along the wide/ long side of the rectangle so you end up with a long skinny roll rather than a short and fat one. Place the swirled roll into a 9x5" bread pan lined with parchment paper. Cover in plastic wrap and let rise until doubled in size, about another 40 minutes. Beat an egg and brush the mixture on top before baking. Bake at 325 F for 30 minutes or until golden brown.

Other Variations I've Tried:

(1) Matcha Green Tea Swirl

For the filling:

1/2 small package of instant vanilla pudding

1/2 cup whole milk

1/2 cup chopped white chocolate

1 1/2 tbsn. matcha powder

To make the filling, whisk the pudding mix and matcha powder together until well combined. Whisk in the milk until smooth and slightly thickened. Allow this mixture to thicken some more in the refrigerator for about 15 minutes.

Prepare the original milk bread as per directions above and let it go through the first proofing. Once the dough has doubled in size, transfer it to a clean surface. Roll out the ball with a rolling pin into an oval shape. Take one end of the dough and fold it to meet the middle of the oval, then take the other end and fold it to meet the middle. Flip the dough over with the folds facing down and flatten with a rolling pin. Roll out the dough until it forms a thin rectangle. Spread the matcha custard all over, leaving a 1cm border around the whole perimeter. Sprinkle with the white chocolate, then roll the top of the rectangle towards the bottom to create a loaf. Place in a parchment paper-lined loaf pan. Cover in plastic wrap and let rise until doubled in size, about another 40 minutes. Beat an egg and brush the mixture on top before baking. Bake at 325 F for 30 minutes or until golden brown.

(2) Raisin-Coconut Custard Swirl

For the filling:

1/2 small package of instant vanilla pudding

1/2 cup whole milk

1 tbsn. brown sugar

1/2 cup raisins

1/2 cup shredded coconut

To make the filling, whisk together the pudding mix and milk until smooth and slightly thickened. Whisk in the brown sugar and shredded coconut. Allow this mixture to thicken some more in the refrigerator for about 15 minutes.

(3) Raisin with Cinnamon-Sugar Swirl (this one was the best, in my opinion)

For the dough: 

1 cup raisins

1 cup hot water

For the filling:

1/4 cup sugar

1 1/2 tbsn. cinnamon

To make the filling, mix the two ingredients until well combined. Soak the raisins in the hot water to allow them to plump up. Drain well, set aside. While preparing the original milk bread, during the kneading of the dough, add the plumped raisins so that they get kneaded in as well. Take a large bowl, grease it with oil, then place the dough into the bowl and cover with a wet towel. Let it proof in a warm place until it's doubled in size, about 40 minutes. Once the dough has doubled in size, transfer it to a clean surface. Roll out the ball with a rolling pin into an oval shape.

Matcha Green Tea Slushie with Boba

Lord knows, I love matcha. I drink tea almost every day of my life. It starts my day and when I'm feeling a bit droopy, it invigorates me. I try to mix it up though, which probably explains why I have 20+ boxes and canisters of tea in my cupboard. I know, it's a bit excessive. Till the end of time, though, my heart will always have a deeper, special spot for matcha. 

When I saw this recipe, I immediately knew I had to make it. It was a simple recipe which I happened to have all of the ingredients for, score! I love when that happens. Anyways, this slushie was exactly like any other matcha green tea slushie you'd get from a tea house! It was perfect: icy, smooth, filled to the brim with matcha flavor and just perfectly sweet. Of course, those little chewy balls of starchy goodness are always welcome too. One ounce of sweetener is the perfect amount - it was just enough to balance out the bitterness of the matcha. 

Matcha Green Tea Slushie with Boba

Yields: 18 oz. (1 - 2 servings)

Original recipe here.

16 oz. cup filled with crushed ice

milk, soy milk or almond milk

1 1/2 tbsn. matcha green tea powder (such as these: Enzo USDA organic matcha powder)

1 oz. Ghiradelli white chocolate syrup (or 1 oz. 1:1 simple syrup)

1/4 cup boba, cooked per package directions

Pour the milk over the ice in the glass until full. Empty the contents into a blender, add the matcha powder and white chocolate syrup. Blend everything until it looks like slushie. Place the boba in the bottom of the glass and top it with the slushie.

Uh oh, it's all gone!!

Matcha Custard Eclairs with Chocolate Ganache

What I love most about making and baking things is just playing around with flavors. Turn a root beer float into a cupcake. Add some kimchi to a pizza. Infuse green tea into EVERYTHING. Oh, how I love it so.

I don't know what happened to my eclairs but for some reason they were oddly flattened. Despite this little detour, they still tasted awesome. I cannot even express how delicious these were! The choux pastry was just barely sweetened, and the bitterness of the matcha powder cut into the sweetness of the custard, so the chocolate glaze added the perfect amount of sweetness and richness that the eclair needed. I loved how the matcha flavor was delicate but still very prominent, and of course, custard. How could you go wrong with custard.

These photos are my ode to matcha. I love, love, love tea and love, love, love matcha green tea even more! It's earthy, rich and luxurious. And bonus, very good for your health.

Matcha Custard Eclairs with Chocolate Ganache

Yields: about 18 5-inch long eclairs

Choux pastry recipe here.

For the pâte à choux:

1/2 cup nonfat milk

1/2 cup water

1/4 tsp. salt

1/4 tsp. sugar

1/2 cup (1 stick) unsalted butter

1 cup flour

5 large eggs

For the chocolate glaze:

4 oz. bittersweet or semisweet chocolate, finely chopped

6 tbsn. unsalted butter

1/2 tbsn. light corn syrup

2 tsp. water

For the green tea custard:

1 small box of instant vanilla pudding

1 cup whole milk

3/4 cup heavy cream

1 tsp. vanilla extract

2 tsp. matcha powder

To make the choux, preheat the oven to 425 F. Line a baking sheet with parchment paper, set aside. In a heavy saucepan, combine the milk, water, salt, sugar and butter and place over medium heat until the butter melts and the mixture comes to a full boil. Add the flour all at once, stirring vigorously with a wooden spoon. Keep stirring until the mixture has formed a smooth mass and pulls away from the sides of the pan and some of the moisture has evaporated, about 3 minutes. Transfer to a bowl of a stand mixer fitted with the with the paddle attachment. Add the eggs one at a time and mix on medium-high speed, incorporating each egg before adding the next. When all the eggs have been added, the mixture will be smooth, thick and shiny.

Transfer the mixture to a pastry bag fitted with the tip of your choice. Pipe out "fingers" about 5 inches long and 1inch wide, spacing them about 2 inches apart. Bake until puffed and starting to show some color, about 10 minutes. Reduce the oven temperature to 375 F and continue to bake until the shells feel light for their size and are hollow inside, about 12 minutes longer. They should be nicely browned all over. Remove from the oven and using a metal skewer, poke a small hole in the end of each shell to allow the steam to escape; this keeps the shells from collapsing. Let cool on racks.

To make the custard, whisk everything together until well combined and begins to thicken, about 3 - 5 minutes. Refrigerate until ready to use. To make the glaze, combine all the ingredients in a small heatproof bowl set on top of a saucepot filled with barely simmering water. Stir frequently until the chocolate is almost completely melted, but do not overheat. Remove the glaze from the water bath and set aside to finish melting, stirring once or twice until perfectly smooth. To assemble, you can either slice the choux pastry in half or use a pastry bag to fill the pastry with the custard. Once filled, dip the tops of the pastries in the chocolate glaze and set on a rack to allow the glaze to set. If desired, you can dust the tops of the eclairs with some extra matcha powder!

Most delicious thing I've eaten in a while!

Green Tea & Strawberry Cupcakes

Today's post will be short and sweet, just like these cupcakes!

Basically, if you combine a perfectly moist little matcha cupcake with the easiest fresh strawberry custard and top it with an impossibly perfect fresh strawberry swiss meringue buttercream, the results are spectacular!

And, of course you cannot deny how impossibly beautiful these things are. I love the combination of this green and pale pink together. But, the combination of green tea and strawberry is much, much better!

Perfectly domed cupcakes :)

1. Take a cupcake.

2. Cut a hole in the cupcake.

3. Fill the hole with strawberry custard.

4. Top with strawberry buttercream!

Green Tea & Strawberry Cupcakes with Custard Filling

Yields: 12 cupcakes

Adapted from here.

For the cake:

3/4 cup + 2 tbsn. cake flour

1/2 cup + 2 tbsn. all purpose flour

1 cup sugar

1 1/2 tsp. baking powder

1/2 tsp. salt

1 tbsn. matcha powder

1/2 cup unsalted butter, softened, cut into 1-inch cubes

2 large eggs

1/2 cup whole milk

1/2 tsp. vanilla

For the custard:

1 small box of instant vanilla pudding

1 cup whole milk

3/4 cup heavy cream

1 tsp. vanilla extract

10 - 15 large strawberries, washed and hulled (more or less, to your taste)

For the SMBC:

2 large egg whites

1/2 cup sugar

1/2 tsp. vanilla

1 1/2 sticks of butter (12 tbsn.), cut into 12 pieces

Strawberry puree or preserves

Preheat the oven to 325 F. Line a cupcake tin with liners and set aside. In the bowl of an electric mixer fitted with the paddle attachment, combine flours, sugar, baking powder, salt and matcha powder. Mix on low speed until combined. Add the butter, mixing until the cubes of butter are peanut sized or a little smaller. In a large glass measuring cup, whisk together the eggs, milk and vanilla. With the mixer on medium speed, add the wet ingredients in 3 parts, scraping down the sides of the bowl before each addition; beat until ingredients are incorporated but do not overbeat. Divide the batter evenly among liners, filling about 2/3 full. Bake until an inserted toothpick comes out clean, 17 - 20 minutes. Transfer to a wire rack and let cool completely.

To make the custard, whip the first four ingredients together until it is well combined and begins to thicken, about 3 - 5 minutes. Place in refrigerator to let chill and thicken some more until ready to use. Chop the strawberries into small dices, and place onto a paper towel lined plate. Place some paper towels on top and place in the refrigerator to allow the water from the strawberries to seep out, about 10 minutes. Once most of the water has been released, fold the strawberries into the custard and continue to refrigerate until ready to use. To make the frosting, put the egg whites and sugar into the bowl of an electric mixer. Place the bowl over a pot of boiling water making sure the bottom does not actually touch the water. Stir the egg whites until the sugar is dissolved. Remove from the heat and place into the mixer stand. Beat until it becomes white and doubles in size. Add the vanilla on low speed, then add the butter, one piece at a time, making sure it is well mixed after each addition. Do not worry if it looks curdled, it will take some time for it to come together. Continue beating for 5 - 10 minutes until everything comes together. Add the strawberry puree or preserves until desired berry taste. Spread/ pipe/ smother onto your cupcakes and enjoy!!

The custard says, "Peek-a-boo!"

French Macarons Galore!

Fellow food bloggers/ bakers, I have a question for you! So I have this problem... sometimes, when I bake the various things that I bake, I really want to be truthful in my description of how the things taste, how they turned out, or how difficult they were to make. The most difficult thing for me though is how things taste.

I know, I know! It really shouldn't be that hard to tell you guys if something is delicious or not but sometimes I really over-think things and examine things to the fine details rather than focusing on the overall deliciousness of the thing! Weird, but I can't help it. Anyway, that's why I always have taste testers - they sure do help a lot with my weird taste bud issues!

So, after all that, on to these macarons! Along with the lavender & vanilla bean macarons I posted a while ago, I made ALL of these too! It was my best friend's birthday and I knew that these would make thee perfect gift, and would let me practice my macaron-making skills, well so I'd hoped.

Weirdly enough, some came out perfect. As for the others, I could not say the same. This was probably due to the fact that I was rushing my macaron making. At first, when tasting them, I was blinded by their slight imperfections. I overcooked the green tea macarons a bit, so they were a bit brown. They were also oddly shaped and didn't have the perfect little feet that I so dreamed of! The lemon though, looked flawless. But besides all of this, my friend told me that they were everything she could have asked for. Yay!

Her favorite were the green tea flavored ones, both the adzuki bean and the passionfruit. I liked the passionfruit a lot because of the tangy and sweet passionfruit buttercream. I also really liked the earthiness that the green tea added to the shells. The lemon mascarpone were also really delicious, super tangy but sweet and I think one of the most beautiful, with perfect smooth shells and some feet!

Green Tea & Adzuki Bean French Macarons

Yields: 2 dozen macarons

Adapted from here.

For the macarons:

1 cup powdered sugar + 4 tsp.

1/2 cup almond powder or meal + 2 tsp.

2 tsp. matcha powder

2 large egg whites, room temperature

5 tbsn. granulated sugar

green food coloring

For the adzuki bean SMBC:

1/2 cup sugar

2 large egg whites

1 1/2 sticks unsalted butter, room temperature

1/4 cup prepared and sweetened Adzuki beans, or more if desired

Preheat the oven to 350 F. Line two baking sheets with parchment paper. Have a pastry bag with a plain tip (about 1/2 inch) ready. In a blender or food processor, grind together the powdered sugar, almond powder/ meal and matcha to make sure there are no lumps. Add the green food coloring to your desired shade of green into the granulated sugar and mix until combined. In the bowl of a standing electric mixer, beat the egg whites until they begin to rise and hold their shape. While whipping, beat in the dyed sugar until very stiff and firm, about 2 minutes. Carefully fold in the dry ingredients, in two batches, into the beaten egg whites with a flexible rubber spatula. When the mixture is smooth and there are no streaks of egg whites, stop folding and scrape the batter into the pastry bag. Pipe the batter on the prepared baking sheet in 1 inch circles (about 1 tbsn. each), evenly spaced 1 inch apart. Tap the baking sheet a few times on the counter to flatten the macarons and let air 'dry' for 1 hour. Bake for 10 - 12 minutes. Let cool completely before removing them.

To make the SMBC, put the sugar and egg white in a large heatproof bowl over a saucepan of simmering water and whisk constantly, keeping the mixture over the heat, until it feels hot to the touch, about 3 minutes. The sugar should be dissolved, and the mixture will look like marshmallow cream. Pour the mixture into the bowl of a stand mixer fitted with the whisk attachment and beat on medium speed until it cools and forms a thick, shiny meringue, about 5 minutes. Switch to the paddle attachment, and add the butter, one tablespoon at a time, beating until smooth. Beat on high speed until it is thick and very smooth, about 6 - 10 minutes. To assemble the macarons, pair the shells off into similar sizes. Take one shell and pipe about 1 tbsn. of the adzui SMBC onto it. Top with the other shell and enjoy!
