Hong Kong Style Milk Tea and Coffee Cream Puffs (Choux au Craquelin)

Turning a famous Hong Kong drink, yuenyeung (鴛鴦, Hong Kong Style Milk Tea and Coffee) into cream puffs! Crispy cookie crust and tasty pastry filled with tea and coffee infused pastry cream. Rich, creamy, irresistible and full of surprises! One bite can be tea flavors and the next can be coffee. Never know what you would get!

For the longest time, I have been wanting to create a recipe with the flavors of this unique Hong Kong drink, yuenyeung (鴛鴦, Hong Kong Style Milk Tea and Coffee). This drink is typically served at cha chaan teng (茶餐廳, Hong Kong style cafe). Many cafes usually do a 70% strong black tea and 30% dark coffee. Then you add evaporated milk and sugar. Every yuenyeung tastes different, because different cafes use different tea blend and coffee brand. The ratio is not always 100%, so every time is a surprise. Some has a stronger coffee taste and some has a stronger tea flavor. This is part of the fun! I love that and yuenyeung is one of my favorite drinks to order.

Pastry Cream

The best way to incorporate the tea and coffee flavors into the cream puffs is infused pastry cream. Instead of making one pastry cream with both flavors, I did two pastry cream. One milk tea and one coffee. A while ago, I did a recipe for Hong Kong Style Milk Tea Popsicles. In that recipe, I used 2 types of black tea, Ceylon tea and Lipton black tea. That worked out really well, so I did the same here. Adding tea leaves and tea bag into hot milk, then letting it steep for 30 minutes. All that tea flavors will get into the milk. Strain out the tea leaves and continue to use the milk to make a traditional pastry cream. For the coffee, I just used instant coffee. Nothing fancy, but it delivered. Pastry cream needed time to cool down, so this can be made a day ahead.

Craquelin (Cookie Crust)

For the cream puffs, I wanted to try the ones with cookie crusts on top. I thought the craquelin (cookie crust) would be tricky to make. But no, it’s super easy and fast. If you have a food processor, pretty much pour everything in and pulse until moist and crumbly. If you don’t, you can still do that by hand. Collect the dough together into a disk, then roll it out into a thin sheet. The key to craquelin is that they need to be frozen. Freeze the sheet for 30 minutes, then cut them out into little rounds using a cookie cutter. Store them in the freezer until ready to use. Make them ahead and give them enough time to be completely frozen.

Cream Puff (Choux)

After talking about the craquelin, we can finally take about the cream puff pastry (choux pastry) itself. Combine milk, water, butter, sugar and salt in a saucepan. Bring to just a boil and stir to make sure everything is melted. Add the flour all at once and stir vigorously with a wooden spoon to form a dough. Continue to cook and stir for the dough to dry out a bit, about a couple minutes. You will see a thin firm formed at the bottom of the pan, then transfer the dough to a mixer. Beat for a minute to release some steam. Now, add in the eggs. I like to lightly beat the eggs first, so you can add little by little. The trick here is to add just enough eggs that the dough is smooth enough, yet pipeable. Yes, you don’t have to use all the eggs! When the dough is ready, it should have a glossy sheen on the surface. The dough should look smooth. When you run a finger onto the dough, there should be a dent and the sides would stay up. Your dough is ready! If your dough is too runny, the puffs will not puffed out in the oven. Unfortunately, you will have to redo the choux.

Piping and Baking

Now, we can get ready to bake. To make sure every cream puff is the same size, there is one extra step. Draw circles on a parchment paper using a cookie cutter. Flip the paper and you can still see the circle lines you drew. That is ready for pipping. Transfer the choux dough into a piping bag. Hold the pipping bag up straight and squeeze out enough dough to fill the circle. Place one of the frozen craquelin rounds on each mound of dough. Bake in the oven until golden brown and crisp on top. The puffs should feel firm and light, and sound hollow when tap on the baking sheet. It’s ok to be a little overbake, but underbake could result in deflated puffs.

Once they’re finished baking, transfer them to a cooling rack. Working carefully, poke a small hole at the bottle of each puff with a paring knife. That hole will let the steam out and make sure the puffs don’t collapse. Be careful, the puffs are very hot. Let the puffs cool completely.

Stabilized Whipped Cream and Cream Fillings

When you’re ready to fill the cream puffs, it’s time to get the cream fillings ready. Instead of just using rich pastry cream as filling, I folded in whipped cream into the pastry cream to lighten up. The problem of whipped cream is that it starts to deflate and weep after a while. By adding melted gelatin in the whipped cream, it will stay airy and fluffy.

Take out the chilled pastry cream and give them a whisk. Then fold in the whipped cream. There are your cream fillings. Finally, we can put them in pastry bags. There is 2 ways to fill the cream puffs. One is to put both tea and coffee cream filling side by side in one pastry bag. So each cream puff get both filling at the same time. The other is to fill 2 pastry bags with 2 different flavors. Fill a cream puff with either flavor first, then follow up with the other flavor. I picked the first method and it worked really well. It’s up to you how you want to do it.

The Final Result

The cream puffs came out above my expectations! When biting into the puffs, I get that crispy crust on top and a nice balanced pastry with cream filling oozing out. It could be milk tea flavor first, then there was the coffee. Every bite was a surprise and you never know whether you will get the taste of coffee or tea. It’s funny because it’s just like the real yuenyeung. You never know whether this drink is going to lean more coffee or tea. Either way, the cream puffs really tasted like the drink and I’m thrilled!

No doubt these cream puffs have many steps and preparation. To make it easier, I highly recommended to divide the work into at least 2 days. On the first day, make craquelin and both pastry cream. On the second day, make the choux pastry, bake, and finish the cream filling. Fill the puffs when you’re ready to serve! This way, it’s much easier to handle and you won’t get overwhelmed. These cream puffs are worth it, and the hard works will be paid off!

I hope you guys will like these as much as we do! Happy Baking!

Instructions

• For the craquelin (cookie crust), in a food processor, pulse the butter, light brown sugar and salt until just blended. Add flour and pulse until the mixture looks moist and crumbly. Add the vanilla and pulse until combined. Transfer the dough to a clean surface and form into round disk. Place the round disk in between 2 parchment papers. Roll the dough out until it is 1/8 – 1/16-inch thick. Transfer the dough along with the parchment papers onto a baking sheet and freeze for 30 minutes. Cut the dough into 1½-inch rounds with a cookie cutter. Freeze the craquelin rounds for at least 1 hour or until ready to use. Discard the rest of the dough.
• For the milk tea pastry cream, in a small saucepan over medium heat, bring milk to a just a simmer. Remove from heat. Add tea leaves and tea bag. Give a quick stir. Cover with a lid and steep for 30 minutes.
• In a medium mixing bowl, stir together sugar, cornstarch and salt. Whisk in egg yolks until mixture is pale yellow and fluffy, about 2 minutes. The mixture will be pretty thick.
• Strain the tea mixture into a measuring cup. Discard the tea leaves and tea bag. Wipe the saucepan clean with a paper towel. While whisking the yolk mixture, slowly pour in milk tea. Return the mixture back to the saucepan. Cook over medium heat, whisking constantly until thicken, about 3 minutes. Pause to check for bubbles. When it starts bubbling, whisk for 30 more seconds. Remove from heat. Whisk in butter until combined. Transfer to a heatproof medium bowl. Cover with plastic wrap by pressing down to the surface of the pastry cream. Chill in the fridge for 3 hours or until cold.
• For the coffee pastry cream, in a small saucepan over medium heat, bring milk to a just a simmer. Remove from heat. Add instant coffee. Give a quick stir. Cover with a lid and steep for 30 minutes.
• In a medium mixing bowl, stir together sugar, cornstarch and salt. Whisk in egg yolks until mixture is pale yellow and fluffy, about 2 minutes. The mixture will be pretty thick.
• While whisking the yolk mixture, slowly pour in coffee milk. Return the mixture back to the saucepan. Cook over medium heat, whisking constantly until thicken, about 3 minutes. Pause to check for bubbles. When it starts bubbling, whisk for 30 more seconds. Remove from heat. Whisk in butter until combined. Transfer to a heatproof medium bowl. Cover with plastic wrap by pressing down to the surface of the pastry cream. Chill in the fridge for 3 hours or until cold.
• For the cream puffs, preheat oven to 375˚F (190˚C). Line 2 baking sheets with parchment papers. Set aside.
• In a small bowl, lightly beat together eggs and egg white. Set aside.
• In a small saucepan over medium-high heat, bring the milk, water, butter, sugar and salt just to a boil, stirring occasionally. Reduce the heat to low. Add the flour all at once and stir until dough forms into a smooth ball and pull away from sides of the pan. Keep stirring until thin-film forms on the bottom of the pan, about 2 – 3 minutes.
• Transfer the hot dough to a large mixing bowl. With an electric mixer fitted with a paddle attachment, mixing on medium-speed for 1 minute to release hot steam. Add 1/3 of the lightly beaten eggs, mix on medium-speed until blended. Add half of the eggs and mix again. Add 1/3 of the remaining eggs, and beat. Check the dough consistency. The dough should be smooth with a glossy sheen, but also stiff enough to be pipeable. You may not need to add all the eggs.
• Transfer the dough to a pastry bag fitted with a ½-inch round tip. Hold the pastry bag straight up and pipe out 12 (1½-inch) mounds on a prepared baking sheet, spacing about 2 inches apart. Do not pipe the other baking sheet yet (bake 1 sheet at a time). Carefully top each dough mound with a frozen craquelin round and press gently to stick.
• Bake in the oven for 10 minutes. Reduce heat to 350˚F (177˚C). Continue to bake for 20 – 25 minutes, until the tops are golden brown, the puffs feel firm when squeezed gently and sound hollow when tapped on the bottom. Do not open oven door during baking. Remove from oven and transfer cream puffs to a cooling rack. While they are still hot, carefully poke a small hole at the bottom center of the cream puff with a paring knife to release any steam inside. Cool completely. Repeat with the second baking sheet. Remember to turn up the oven to 375˚F (190˚C) to start.
• For the stabilized whipped cream, in a small microwave-proof bowl, add water. Sprinkle the gelatin powder over evenly. Set aside to soften for 10 minutes. Microwave for 10 – 15 seconds. Stir to dissolve.
• In a large mixing bowl with an electric mixer fitted with a whisk attachment, add heavy cream and powdered sugar. Whisk for 1 minute at medium-high speed. Pour the warm gelatin liquid into the cream. Continue to whisk until soft peaks form. Cover and keep in the fridge until ready to use.
• When almost ready to serve, prepare the cream fillings. In two medium mixing bowls, add milk tea pastry cream in one bowl and coffee pastry cream in another. Whisk them separately to smooth out. Add 1/3 of whipped cream into each pastry cream. Gently fold in the whipped cream until blended.
• There are 2 ways to fill the cream fillings into pastry bag(s). Make sure the pastry bag(s) is fitted with a round or star tip. Method 1: Fill both milk tea and coffee cream filling side by side into a single pastry bag. Use a small spoon to place the cream into the bag. It won’t be perfect, but it’s ok. Method 2: Fill the 2 cream fillings into 2 different pastry bags. One flavor in one bag.
• To assemble, hold a cream puff on one hand, and hold a pastry bag on another hand. Insert little bit of the tip of the pastry bag into the small hole at the bottom of the puff. Squeeze the cream filling into the puffs. When you see the filling starts to spill out the sides of the hole, it’s full. Continue to fill the rest of the cream puffs. If using 2 pastry bags (one flavor in one bag), fill one flavor first, then fill the other. It will be a bit hard to tell how much you fill, but just do your best. It doesn’t have to be perfect. Serve immediately or within 30 minutes.

Notes

1. Cool unsalted butter*: I cut the butter into small cubes and let them sit at room temperature for about 20 – 30 mins. They are still cool to touch and not at room temperature.
2. Craquelin without food processor: Butter needs to be at room temperature. In a medium bowl, mash together butter and brown sugar. Add flour and salt, mix until the mixture is moist and crumbly, about 2 minutes. Stir in vanilla extract at the end. Then continue with the craquelin steps in the recipe above.
3. Craquelin need to be frozen and should be frozen when you place onto the choux when baking.
4. A traditional Hong Kong milk tea uses a blend of black tea. I used both Ceylon tea leaves and Lipton tea bag. If you want, you can just use Ceylon tea leaves and skip the Lipton. I got my Ceylon tea online from Harney & Sons. The one I got is Orange Pekoe. 
5. If the choux batter is too runny, the puffs may not rise in the oven and they could be flat. It’s better to remake your batter.
6. To make sure all cream puffs are the same size, use a template. Draw 12 (1½-inch) circles on the parchment papers. Then flip the papers and use the side without pen marks. You will still be able to see the circle lines.
7. Make ahead: Craquelin can be made 1 month ahead and freeze in an airtight container. Pastry cream can be made 3 days ahead and store in an airtight container. Stabilized whipped cream is best to make on the same day and fold into pastry cream right away. Unfilled cream puffs are best on the same day, but can be made 1 day ahead. Keep in an airtight container in the fridge. Reheat in a 300˚F oven for 10 minutes. Cool before filled.
8. This recipe includes lots of steps and details. I highly recommended to divide the work into at least 2 days. Day 1: make craquelin and both pastry cream. Day 2: make the choux pastry, bake, and finish the cream filling. Fill the puffs when you’re ready to serve. This way, it’s much easier to handle and you won’t get overwhelmed.
