The perfect cake for any occasion Magic Custard Cake has three layers of deliciousness. The bottom layer is a silky smooth dense layer of cake topped with a layer of chocolate custard and a spongy cake.Magic Chocolate Custard Cake

L.J. recently returned from outdoor school and I wanted to surprise him with a special treat for dessert when he came home. So I made this Magic Chocolate Custard Cake I've been eyeballing on Pinterest for sometime from White On Rice Couple and new it was meant to be.

This cake is fairly simple to make and magically separates into 3 layers of deliciousness.

A silky smooth dense bottom layer followed by a chocolaty layer of custard topped with a light layer of cake.

If that's not magical I don't know what is.

Mix together flour, salt and cocoa powder until well blended.
I made this recipe for a 9x13 because with 5 people in our house a 8x8 never lasts long and it's a good thing too because Colt ate 3 pieces on the first night.
In a medium sauce pan over medium-low heat melt butter, remove from heat and add chocolate chips. Stir until chocolate chips are melted and remove from heat to cool for a minute.
Butter a 9x13 pan and line with parchment paper. Butter parchment paper well.
I use parchment paper because it makes it easy to remove the cake from the pan for slicing, its not mandatory but does make it much easier to remove.
Beat 8 egg whites with 1/4 teaspoon of vinegar until stiff peaks form.
Remove egg whites from bowl and set aside.
Clean mixing bowl and add melted butter mixture and powdered sugar. Beat on medium speed until well combined.
Heat milk over medium-low heat until lukewarm. Make sure milk isn't too hot or it will scramble the eggs.
Add eggs one at a time to the butter sugar mixture while mixing on medium speed.
Scrape sides of bowl and add strong coffee. Mix until well combined.
Your mixture should be smooth and creamy just like this!
Add flour/cocoa powder mixture and stir until well combined.Scrape sides of bowl well.
Slowly mix in milk on low. If milk is splattering you can hand stir in milk until well combined.
Batter should be smooth and creamy.
Fold in egg whites 1/4 at a time to the cake batter until well combined.
Batter won't be completely smooth, that's ok thats the light spongy cake layer on top once it bakes.
Bake that bad boy in a 325 degree oven for 55-65 minutes or until cake is still slightly loose in the center but set around edges when pan is moved.
Cool cake completely and dust cake with powdered sugar and cocoa powder.
Slice into desired size.

I strongly suggest whip cream and fresh berries for serving.

  1. It's like and upside down chocolate pudding! So nice!

  2. Goodness sakes, this looks beyond delicious! Those layers and richness are amazing - and it is such a simple recipe! Love it!

  3. I've seen custard cakes before but what makes this one outstanding is that it used parchment so you could later remove it from the pan to serve on a plate—much more elegant!

    2. Thanks Mia. I agree that was the big problem when I was looking at the original recipe is how we were going to have something easy to work with once it was baked, the parchment worked beautifully!

  5. Whoa! This would scratch my chocolate itch for sure!! Yummm!
