Magic Custard Cake

When I first heard about this cake, I was both fascinated and curious. You only need to make one batter and it separates into 3 layers upon baking, with a custard centre layer. How magical is that? Oh, the wonders of food chemistry! And it sounds delicious too!

With my hubby's birthday coming up, I quickly bookmarked it for this special occasion. In fact, it was so good, I made it again for my mom's birthday a few days' later!

Birthday Magic Custard Cake with Chocolate letters by my girl

Recipe adapted from Taste-E 

½ cup (113g)  unsalted butter
2 cups milk
4 eggs separated, brought to room temperature
1/8 teaspoon cream of tartar
150g icing sugar
1 Tablespoon water
1 teaspoon vanilla bean paste (or good quality vanilla extract)
1/8 teaspoon salt
115g flour


1) Line an 8x8 inch baking pan with parchment paper.  Preheat oven to 160C.

2) Melt butter in the microwave, and leave to cool.

3) Warm milk in a saucepan to lukewarm. Set aside.

4) Beat egg whites until a bit frothy.  Add cream of tartar and beat until stiff.  Set aside. 

5) Beat egg yolk and sugar until light.  Add vanilla and salt and beat until mixed.

6) Add butter and water and beat for 2 minutes. Add flour and mix until incorporated.

7) Pour in milk and whisk until smooth and incorporated.

8) Fold in egg whites 1/3 at a time, using a whisk.  It will have some small lumps of whites.

9) Pour in prepared baking pan – it will be very runny.  Bake for 45-60 minutes or until the top is golden and the middle is still a bit jiggly. Cool, then refrigerate until cold. Store in the fridge.


  1. hi Sandy, i saw a few of this magic cake before but yours look best so far! Can I know when u say sprinkle toffee and chocolate on top u mean before baking?? What kind of chocolate r u referring too? Chocolate powder? WIll it affect the cake texture if we don't put toffee and chocolate? Thanks!

    1. Hi Eely, thanks for your compliment! Oh, sorry, the part about the toffee and chocolate bits on top is actually optional. I didn't put them when I baked my cake. No, it doesn't affect the cake at all if you don't put them. Thanks for your highlight. Guess I'll remove the instruction from my recipe to avoid confusion. One important thing to note is to make sure you beat the egg white till stiff.
