How to Make Taiwanese Castella Cake
-
Prepare Baking Equipment: Preheat your oven to 300°F (150°C). Line an 8x8x3 inch pan with parchment paper, letting it extend about 1 inch above the edges for easy removal. If the pan isn’t solid, wrap it with aluminum foil to keep the water bath from seeping in.
-
Water Bath Setup: Heat some water in a kettle or pot until it reaches around 175°F (79°C), which will create a gentle steam while baking.
-
Sift Dry Ingredients: In a mixing bowl, sift together the cake flour and salt to ensure that they’re light and free of lumps. This step is crucial for achieving that fluffy texture!
-
Combine Wet Ingredients: In a saucepan, gently melt the unsalted butter and whole milk together until it reaches around 120°F (49°C). Once melted, mix this with the sifted flour until combined.
-
Mix Egg Yolks: One by one, incorporate the egg yolks into the flour mixture, followed by the vanilla extract, blending until the mixture is smooth and well combined.
-
Make Meringue: In a clean bowl, beat the egg whites with cream of tartar at low speed until foamy. Gradually add granulated sugar and increase the speed until soft peaks form, creating a luscious meringue.
-
Fold Mixtures: Gently fold the meringue into the egg yolk mixture in thirds, watching for the color to become uniform—if you overfold, you risk losing that beautiful fluffiness!
-
Bake: Pour the batter into your prepared pan from about 12 inches high to help release any trapped air bubbles. Place it into the water bath and bake for 65-70 minutes, or until the cake is golden and set in the center.
-
Cool and Serve: Allow the cake to cool for about 2 minutes before removing it from the pan. Keep in mind that it will slightly deflate as it cools, but that’s perfectly normal!
Optional: Serve with whipped cream and fresh berries for an added touch of sweetness.

Right Temperature: Make sure the water bath is hot but not boiling to ensure even baking and prevent evaporation throughout the process.
