Fluffy fa gao prosperity cake that blooms when steamed symbolizes rising fortune. A festive family dessert with sweet, airy texture.
Prepare a steamer by bringing water to a rolling boil over high heat and line muffin cups with baking paper.
In a large bowl, whisk together cake flour, rice flour, and baking powder until evenly combined.
In a separate bowl, beat the egg with sugar, water, vegetable oil, and vanilla extract until the sugar dissolves.
Pour the wet mixture into the dry ingredients and mix gently with a spatula just until a smooth, thick batter forms; avoid overmixing to maintain aeration.
Quickly spoon the batter into prepared cups, filling each almost to the top for a dramatic bloom.
Immediately place the filled cups into the steamer, making sure the steam is strong, and steam over high heat for 15–18 minutes without uncovering, until cakes split and bloom at the top.
Remove carefully and cool slightly before serving, ensuring not to oversteam to preserve their airy texture.
