Tips For Successful Gluten-Free Vanilla Cake With Custard Filling

Gluten-Free Flour Blend: Use recommended gluten-free flour for best results. This flour is triple-tested in this recipe to ensure the cake is light and moist.

Don’t Overmix: Once the dry ingredients are just incorporated, stop mixing. Overmixing can lead to a tough and dense cake.

Eggs and Wet Ingredients: It’s best to be at room temperature. It will give the cake a better rise and keep it light.

The Custard: The custard should be completely cooled before spreading it over the batter, or it will sink to the bottom.

Flavor Twists:

Chocolate Cake: For the custard, beat 2 teaspoons of pure cocoa powder with eggs, sugar, and tapioca powder before adding milk. For the cake batter, whisk 1/4 cup of pure cocoa powder with dry ingredients. 

Lemon Cake: Mix 1 teaspoon of fresh lemon juice with custard mixture and mix 2 tablespoons of lemon juice and zest of 1 lemon with the cake batter.

Lemon or Vanilla glaze: For an extra burst of flavor, drizzle a simple glaze over the cooled cake. To make a glaze, whisk together powdered sugar and lemon juice or powdered sugar, milk, and vanilla until smooth.

Fresh Berries: Add fresh berries like strawberries, raspberries, or blueberries.  They add freshness, and healthiness to the cake.


The cake can be stored at room temperature for a day in an airtight container. For longer storage, you can refrigerate it for up to 3 days.
