Fluffy ma lai gao steamed sponge cake with rich, caramelized flavor is a dim sum classic. A family dessert with soft, bouncy texture.
In a large mixing bowl, whisk together eggs and brown sugar until creamy and pale, ensuring even aeration for a light texture.
Sift cake flour, baking powder, and baking soda onto the wet mixture for thorough blending and to prevent lumps.
Gently fold in evaporated milk, melted butter, and vanilla extract, keeping the batter smooth; avoid overmixing for a tender crumb.
Let the batter rest for 20 minutes at room temperature, allowing baking powder to activate and maximum fluffiness to develop.
Pour batter into a parchment-lined steamer pan. Steam over medium-high heat for 40–45 minutes; do not lift lid during steaming to preserve moisture and rise.
Once cooked, turn off heat, let Ma Lai Gao sit in closed steamer for 5 minutes, then carefully remove and cool before slicing to maintain its bouncy texture.
