Ingredients

What you'll need to make this Magic Custard Cake recipe:
- 4 large eggs, separated, at room temperature
- 1 cup of baker’s sugar (superfine sugar)
- ½ cup of salted butter, melted and cooled
- 2 teaspoons of vanilla extract
- 1 cup all-purpose flour
- 1 ½ cups of whole milk, lukewarm
- ½ cup of heavy cream, lukewarm
Pro Tip
Baker’s sugar is not the same as granulated sugar or confectioner’s sugar. Look for sugar that is labeled superfine or caster sugar. If you cannot find this type of sugar, you can make your own by running 1 cup plus two teaspoons of granulated sugar through a food processor for 30 seconds.
Substitutions and Additions
Make this magic custard cake your own by swapping out ingredients and adding delicious extras! Here are some top substitutions and additions:
Add cocoa powder: Mix in a tablespoon of cocoa powder for a light chocolate flavor throughout the cake.
Substitute milk: Use coconut milk or almond milk for a subtle, unique twist in the custard layer of your magic custard cake.
Add vanilla bean: Swap vanilla extract for vanilla bean paste to give the cake a rich, authentic vanilla flavor.
Try lemon zest: Add a teaspoon of lemon zest for a bright, citrusy note that complements the creamy custard layers.
These substitutions and additions can easily be swapped out while still maintaining the deliciousness of this creamy custard pie.
How to Make Magic Custard Cake
Follow along with our pictures and step-by-step instructions to make this magic custard cake. Let’s get started on baking this delicious, layered dessert that you're sure to love!
Pro Tip
The recipe can be doubled and baked in a 10×10 square baking dish. Bake for about 60 minutes.
FIRST STEP: In a large bowl, beat the egg yolks and sugar until pale yellow and creamy, about 1 to 2 minutes.

SECOND STEP: Add the cooled melted butter and vanilla extract to the mixing bowl then beat to combine fully. Beat in the flour.

THIRD STEP: Combine the milk and cream together and slowly pour into the batter, mixing to combine.

FOURTH STEP: Beat egg whites with a stand mixer with the whisk attachment until stiff peaks form.

FIFTH STEP: Use a large whisk to lightly incorporate the whipped egg whites into the batter. Add the egg whites in 2 to 3 additions and only whisk slightly. The batter will have two distinct textures – a very thin, runny batter with the lightly incorporated egg whites floating on the top of the batter.

Pro Tip
While we would suggest only removing one piece at a time from the pan, if for some reason you do want to remove the entire cake at once, lining the pan with parchment paper may help to lift the cake out of the pan. We can’t guarantee that you won’t get a bit of custard that will try to ooze out the side of the cake.
SIXTH STEP: Pour batter into an 8×8 square baking pan that has been greased with butter.
Pro Tip
The 8×8 square pan is important to achieve the three distinct layers. A larger pan will spread the cake batter too thin for the custard layer in the center to form. The batter won’t fit in a smaller pan.

SEVENTH STEP: Bake for approximately 40 to 45 minutes in an oven preheated to 325°F. The cake is done when the center is still jiggly, but the batter does not slosh in the pan. The top will be lightly golden brown.
Pro Tip
The low temperature (325°F) is important for baking this custard-like dessert.

EIGHTH STEP: Remove from the oven and allow to cool completely.
NINTH STEP: Allow the cake to sit for 2 to 3 hours before dusting with powdered sugar and cutting into 9 pieces. It is best to remove the pieces from the pan one at a time rather than trying to remove the entire cake at once.
Pro Tip
To cut the cake cleanly, pop your knife in the freezer to cool it, and it should slice through the cake easily.
