Why you will love this cake
- Balanced sweetness: the cake is sweet but not cloying, and the brown sugar boba adds a pleasant chewy contrast.
- Authentic milk tea flavor: the concentrated tea infusion gives the cake a recognizable milk tea taste that boba fans will love.
- Pantry-friendly: most ingredients are common baking staples.
- Beginner-friendly: the steps are straightforward and forgiving.
Components of the cake
The cake has three main elements: the cake layers, the frosting, and the boba topping.
- Milk Tea Butter Cake – A reverse-creamed butter cake flavored with concentrated milk tea and reinforced with a tea-infused simple syrup. The crumb is tender but stable enough for three layers.
- Cheese Buttercream Frosting – Inspired by cheese foam toppings, this frosting is light and fluffy and pairs nicely with the tea-flavored cake.
- Brown Sugar Boba – Cooked tapioca pearls tossed in brown sugar provide chewy bursts and visual interest on top of the cake.
What type of cake is it?
This is a variant of a classic butter cake, using butter, flour, sugar, eggs, baking powder, and salt. The twist is that milk and simple syrup are infused with black tea, and the batter is made using the reverse cream method to produce a tender, low-domed layer cake.
Why the reverse cream method?
The reverse cream method yields a delicate, uniform crumb and produces flatter layers—ideal for stacking. It incorporates less air than traditional creaming, reducing doming and cracking. Although the method can lead to longer bake times, adding sour cream keeps the cake moist during baking.
How to plan your time
While the steps are simple, the full process is time-consuming. You can complete everything in one day, but splitting the work across two to three days makes the project more relaxed:
- Day 1: Infuse the milk and make the tea syrup.
- Day 2: Bake the cake layers and prepare the frosting.
- Day 3: Cook the boba and assemble the cake.
Everything except the brown sugar boba stores well ahead of time, so you can spread the work out without rush.
How to store and serve
Unfrosted cake: Store at room temperature up to 3 days or refrigerate up to a week, wrapped tightly.
Frozen: Unfrosted cakes, frosted cakes, and individual slices can be frozen up to 3 months—double-wrap and label. For a frosted cake, freeze briefly uncovered until the frosting firms, then double-wrap. Thaw overnight in the fridge and bring to room temperature before serving.
Buttercream: Keep refrigerated up to 1 week or freeze up to 2 months. Warm or remix before using.
Brown sugar boba: Best used within a few hours at room temperature; tapioca firms as it cools, making it less pleasant if stored too long.
Tips and tricks for making an amazing cake
- Use a digital scale for accurate ingredient measurements.
- Room temperature ingredients—butter, eggs, and cream cheese incorporate more smoothly when not cold.
- Plan ahead—syrups and infusions need time to cool or steep.
- Use extra tea bags for a pronounced tea flavor. See Note 1 below.
Note 1. To achieve a strong tea flavor, steep extra tea bags overnight. It may feel like a lot of tea, but it enhances the cake’s profile.

Recipe
Make the milk tea

Make tea-infused simple syrup
- Dissolve sugar in hot water until clear. Add 3 tea bags and steep for 30 minutes. Cool to room temperature before using or refrigerate overnight.
Bake the cake
- Preheat oven to 350°F (175°C).
- Sift and combine all dry ingredients in a bowl.
- Add butter to the dry mix and beat 1–2 minutes until evenly distributed; the mixture will be sandy and crumbly. (Total beat time should not exceed 5 minutes.)
- In a separate bowl, whisk eggs and add milk tea.
- Beat the egg mixture into the dry mixture in three additions.
- Stir in sour cream until the batter is smooth.
- Grease three 6″ pans, line with parchment, and grease the parchment.
- Divide batter evenly among the pans (about 400 g batter per pan if total is ~1200 g).
- Bake 27–30 minutes at 350°F or until a toothpick comes out clean. Cool in pans 20 minutes, then transfer to racks to cool completely before assembly.
Make cheese buttercream frosting
- Beat butter and cream cheese until smooth.
- Add powdered sugar, milk, vanilla, and salt. Beat 2–3 minutes until fluffy.

- Turn off the heat, cover, and let rest 20 minutes.
- Drain and rinse briefly with cold water to stop cooking.
