Ingredients

  • 1 1/3 cups 150 grams cake flour (not all purpose!)
  • 1 1/2 teaspoons baking powder
  • 3/8 teaspoon salt
  • 1/2 cup buttermilk room temperature
  • 1 teaspoon vanilla extract or a combo of vanilla and almond extract
  • 1 stick 114 grams unsalted butter softened
  • 3/4 cup plus 2 tablespoons 175 grams granulated sugar
  • 2 1/2 large egg whites 82 grams room temperature from 3 large eggs (SEE NOTE)
  • 1 tablespoon heaping colored sprinkles

American Style Buttercream

  • 1 1/2 sticks unsalted butter softened (168 grams)
  • 2 1/4 cups confectioners’ sugar 270 grams
  • 3 tablespoons heavy cream plus more cream (or milk) as needed
  • 1 teaspoon vanilla or vanilla bean paste

Instructions

  • Preheat oven to 350 degrees F. Grease and flour two 6-inch round cake pans.
  • First, weigh your flour then sift it with the baking powder. Stir in the salt (it tends to get clogged in the sifter, so it’s best to just stir it in after. Set aside.
  • With an electric mixer, beat the butter and sugar until light and fluffy, scraping sides of bowl often. Beat in the vanilla and almond extract.
  • Using a rubber scraper to stir, add the milk and flour mixture to the batter in thirds, alternating (milk, flour, milk, flour, milk, flour) and stirring until blended. It will be very thick at this point. I
  • With the electric mixer, beat on medium high speed for 20 seconds or until batter is free of lumps and all flour is incorporated.
  • In a clean bowl using clean beaters, beat the egg whites until stiff peaks start to form. Discard 1/3 cup (17 grams) of the beaten egg white and fold the remainder (about 82 grams) into the batter.
  • Stir sprinkles into the cake batter (if using), then divide between the two pans. You should get somewhere around 10 oz/280 grams per pan.
  • Bake at 350 for 28 to 30 minutes. Let cool on a baking rack for 10 minutes, then carefully turn from pans. Let cool completely.
  • To make the frosting, beat the butter with an electric mixer until fluffy, then gradually beat in the confectioners’ sugar. Beat in the cream and vanilla, using more cream (or adding a little milk) to thin if needed.

Notes

The original egg white measure was 5 egg whites, so rather than halve one raw egg white to make 2 ½ egg whites, it’s better to just whip 3 egg whites until stiff peaks form, then discard about 17 grams of whipped egg whites (1/3 cup) before folding into the batter.
