Berry Custard Cake

I’m seriously loving the deep purple color of this custard cake. A custard cake that started off with every intention of being a blueberry magic custard cake—I failed.

The layers aren’t distinct like with a traditional magic custard cake, but that’s because I screwed up the order of when to mix the liquids in—twice. And the second time around I ran out of blueberries, so I topped the custard cake with blackberries—even though the cake is colored and flavored with dehydrated blueberries.

I”m totally blaming my prego brain for all the missteps. Grrr!

On a positive note, this is custard cake is still awesome tasting.

  • 4 eggs, separated, at room temperature
  • ½ cup + 2 tablespoons  sugar
  • 1 tablespoon water
  • 2 tsp vanilla extract
  • 1 stick butter, melted

  2. Place egg yolks, remaining sugar, water and vanilla into stand mixer bowl fitted with a whisk attachment until mixture is pale, fluffy and ribbons on itself when whisk attachment is gently lifted, about 5-7 minutes. With the mixer running, gradually add the melted butter down the side wall of the bowl , continue beating for another minute.  Sift pulverized dehydrated blueberry and flour into egg yolk mixture and gently fold until incorporated. Add lukewarm milk (do not use cold milk or the butter harden) and beat until well incorporated. Gently fold in beaten egg whites mixture.

    Let’s be honest, blackberries are pretty rockin. Have no doubt this cake was just bursting with flavors. And blame your prego brain all you want. You can tell the kiddo what a mess their mom was and how she kept screwing up her recipes. 😉
