- 200 g taro, peeled and cubed
- 60 ml whole milk
- 2 black tea bags (or 4 g loose-leaf Assam)
- 120 ml hot water
- 4 large eggs, separated
- 120 g granulated sugar, divided
- 60 ml neutral oil
- 100 g cake flour, sifted
- 6 g baking powder (1 tsp)
- 2 g salt (1/4 tsp)
- 1/2 tsp vanilla extract
- 150 ml cold whipping cream (35% fat)
- 20 g powdered sugar
- Brew the milk tea: Steep tea bags in 120 ml hot water for 5 min; discard bags and cool.
- Steam taro until fork-tender, about 15 min. Mash and blend with 60 ml milk until smooth. Reserve 80 g for batter; chill the rest for frosting.
- Preheat oven to 170 °C (340 °F). Line the bottom of an 8-inch (20 cm) round cake pan with parchment; leave sides ungreased.
- Whisk egg yolks with 60 g sugar until pale. Add oil, cooled milk tea, vanilla, and 80 g taro purée; whisk smooth. Fold in flour, baking powder, and salt.
- Beat egg whites to soft peaks; gradually add remaining 60 g sugar and whip to medium-stiff peaks.
- Fold one-third of whites into yolk batter, then gently fold in the rest until just combined.
- Pour batter into pan, tap once to release bubbles, and bake 30–35 min until a skewer comes out clean.
- Invert pan on a rack; cool completely before unmolding.
- Whip cream with powdered sugar to soft peaks; fold in remaining taro purée.
- Frost cooled cake with taro whipped cream and chill 30 min before slicing.
Notes
- For stronger tea flavor, steep leaves in hot milk instead of water.
- Swap Assam for Earl Grey for a floral twist.
- Ensure mixing bowls for egg whites are grease-free.
- Cake keeps refrigerated up to 3 days.
