MAGIC CUSTARD CAKE INGREDIENTS

magic custard cake raw ingredients that are labeled

You will need:

  • 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

Toppings: Dust the top of the cake with confectioner’s sugar and add fresh berries for the perfect presentation.

Sugar: Powdered sugar or granulated sugar can also be used in the recipe. If you want to stick with the baker’s sugar but can’t find it in the store, follow the above tip to convert regular white sugar into baker’s sugar at home.

Milk: Two cups of regular milk can be used instead of the milk/cream combination in the recipe.

HOW TO MAKE THIS MAGIC CUSTARD CAKE RECIPE

PRO TIP: The recipe can be doubled and baked in a 10×10 square baking dish. Bake for about 60 minutes.

STEP ONE: In a large bowl, beat the egg yolks and sugar until pale yellow and creamy, about 1 to 2 minutes.

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

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

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

STEP FIVE: 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.

STEP SIX: 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.

STEP SEVEN: 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.

STEP EIGHT: Remove from the oven and allow to cool completely.

STEP NINE: 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.

HOW TO SERVE

Serve this vanilla magic custard cake right away for dessert. Add a scoop of no-churn vanilla ice cream and a spoonful of homemade whipped cream on top of your layer cake.

Serve with our iced tea, raspberry iced tea, sweet peach iced tea, or our southern strawberry sweet tea on the side to wash this delicious dessert down.

STORAGE

IN THE FRIDGE: This magic three-layer custard cake recipe is best eaten right away, but you can store it in the refrigerator in an airtight container or covered in aluminum foil for 1 to 2 days.

IN THE FREEZER: We do not recommend freezing this delicious cake.

The sweet vanilla taste of custard is one of my favorite flavors. This magic cake recipe is heavenly and comes out with three distinct, separate layers that differ in both look and texture. It is an incredibly elegant dessert that is melt-in-your-mouth amazing.

FAQ

Is my batter supposed to be very runny?

Yes, you will have a very runny and thin batter, and that is the consistency you want for the magic layering to happen.

Is baker’s sugar the same as white or confectioner’s sugar?

Baker’s sugar is different from both white and confectioner’s sugar. It is a superfine granulated sugar. Regular white sugar is coarser, and confectioner’s sugar is more on the powdery side. If you can’t find baker’s sugar in the store, you can make your own by putting regular white in the food processor for about 30 seconds.

Are there other flavors of this unique cake?

You can find a recipe for pumpkin magic cake on this site. Lemon and chocolate magic cakes are also popular variations on this classic vanilla magic custard cake recipe.

Can I use almond milk in this recipe?

We have not tried using almond milk, although I have heard of other people having success. You may find that your cake may not turn out exactly the same as with regular milk.

    I am gluten free and want to try this recipe. What type of flour could I use instead of regular flour?

  2. Patricia says

    How hard is it getting the cake out of the pan? The recipe says after removing from the oven allow the cake to cool completely. Do you remove it from the pan at that point? Is there a technique for removing it from the pan to a plate without messing up the custard?
