DIRECTIONS
☕ Step 1: Milk Tea Infusion
- In a small pot, bring milk to a simmer.
- Add black tea leaves and steep for 30 minutes.
- Strain the tea and set aside to cool.
🍰 Step 2: Cake Layers
Ingredients:
- 310g cake flour (divided: 200g + 110g reserved)
- 300g sugar
- 2½ tsp baking powder
- ½ tsp salt
- 170g unsalted butter (room temp)
- 3 eggs
- 1 egg white
- 200ml milk tea (from Step 1)
Instructions:
- Preheat oven to 177°C (350°F). Grease three 6-inch round cake pans.
- Sift the flour. In a stand mixer fitted with a paddle, combine:
- 200g flour, sugar, baking powder, and salt.
- Add butter in two additions and mix until pale and fluffy.
- In a separate bowl, whisk together the milk tea, eggs, and egg white.
- Add half of the liquid mixture to the dry mix. Mix on medium until incorporated. It may look slightly curdled.
- Add the remaining 110g flour, then the rest of the wet mixture. Mix just until smooth.
- Divide batter evenly into the pans and bake for 11–13 minutes, or until a toothpick comes out clean.
- Let cool in pans for 10–15 minutes, then transfer to a wire rack to cool completely.
🍯 Step 3: Black Tea Simple Syrup
- In a small pot, combine equal parts sugar and water.
- Bring to a boil until sugar dissolves.
- Remove from heat, add black tea, and steep for 20 minutes.
- Strain and let cool to room temp.
🍼 Step 4: Milk Tea Concentrate
- Simmer milk until warm (do not boil).
- Remove from heat, add black tea, and steep for 30 minutes.
- Strain and chill. Set aside for buttercream.
🧈 Step 5: Milk Tea Buttercream
Ingredients:
- Egg whites (from about 3 large eggs)
- Sugar 1 (for syrup)
- Water
- Sugar 2 (added to egg whites)
- Unsalted butter (cubed, room temp)
- Milk tea concentrate (from Step 4)
Instructions:
- In a mixer bowl, begin whipping egg whites on low speed with the whisk attachment.
- Meanwhile, heat Sugar 1 and water in a saucepan until it reaches 120°C (248°F).
- When the syrup reaches 100°C, increase the mixer to medium and add Sugar 2 to the egg whites.
- Once the syrup hits 120°C, slowly pour it into the egg whites while whipping on medium.
- Continue whipping until the bowl is cool to the touch and the meringue holds stiff peaks.
- Add butter a few pieces at a time. If the mixture curdles, keep whipping on high until it smooths.
- Add milk tea concentrate and whip until fully incorporated.
🧋 Step 6: Boba
- Bring a small pot filled 2/3 with water to a boil.
- Add boba pearls and cook for 10 minutes, then simmer for another 10 minutes.
- Stir in brown sugar and simmer until dissolved.
- Keep warm until ready to serve. Do not refrigerate.
🎂 Step 7: Assembly
- Place the first cake layer on a serving plate. Brush with black tea syrup.
- Add a layer of milk tea buttercream.
- Repeat with the second and third layers.
- Frost the outside of the cake with the remaining buttercream.
IMPORTANT:
⏰ Only add warm boba just before serving—never refrigerate the cake with boba or they will harden. Boba stays soft for only a few hours after serving.
Slice and serve with additional warm tapioca pearls on top or on the side.
