Allrecipes: David's Yellow Cake

My nephew doesn't like sweets.  Not really.  I know!  We must not really be related.  It's a shocking turn of events.  So when it comes time for his birthday, I'm a bit at a loss for what to do about a cake.  What birthday cake do you make for someone who doesn't really like cake?  So my sister suggested a plain yellow cake with some chocolate frosting.  Just use a box mix, she says.  Nice and simple.  So what did I do?  I found the best danged from-scratch cake recipe I could and made a beautiful yellow cake.  What did the kids at the party do?  Licked the frosting right off the top.  They don't know what they're missing.

David's Yellow Cake
From Allrecipes

1 cup unsalted butter
1½ cups granulated sugar
8 large egg yolks
¾ cup whole milk
1½ teaspoons vanilla extract
2 cups cake flour
2 teaspoons baking powder
½ teaspoon sea salt

Chocolate Frosting

Preheat oven to 350°F. Grease and flour 2 8-inch round pans. Sift together the flour, baking powder, and salt. Set aside.

In a large bowl, cream together the butter and sugar until light and fluffy. Beat in the egg yolks one at a time, then stir in the vanilla. Beat in the flour mixture alternately with the milk, beginning and end with flour, mixing just until incorporated. Pour batter into prepared pans.

Bake in the preheated oven for 25 to 30 minutes, or until a toothpick inserted in the center comes out clean. Cool 15 minutes before turning out onto cooling racks.

Chocolate Frosting
9 tablespoons unsalted butter
4 cups powdered sugar
2 teaspoons vanilla extract
6 to 9 tablespoons milk
½ cup cocoa powder

Mix together the butter, sugar, vanilla extract, and 6 tablespoons of milk until smooth. Add cocoa powder and enough additional milk to make the frosting spreadable.
