Ingredients

  • 1/2 cup fine yellow cornmeal
  • 1/2 cup cake flour
  • 1 teaspoon baking powder
  • 1/2 cup (1 stick) unsalted butter, at room temperature
  • 1/4 cup almond paste, cut into small pieces
  • 1/2 teaspoon pure vanilla extract
  • 1 1/4 cups confectioners sugar, plus more for dusting
  • 4 large egg yolks
  • 2 large eggs
  • 1/4 cup sour cream

Method

  • Position the rack in the center of the oven and preheat the oven to 350 degrees F. Butter and flour an 8-inch round cake pan.
  • In a medium bowl, whisk together the cornmeal, cake flour, and baking powder.
  • Using a stand mixer with a paddle attachment, beat the butter and almond paste on high speed until smooth, about 3 minutes.
  • Reduce the speed to low and beat in the vanilla extract.
  • Gradually add 1 1/4 cups of confectioners sugar, beating until the mixture is light and fluffy, about 3 minutes.
  • Increase the speed to high and beat in the egg yolks and whole eggs, one at a time.
  • Reduce the speed to medium and add the sour cream and dry ingredients and mix until just incorporated.
  • Pour the batter into the prepared cake pan and smooth the surface with a spatula.
  • Bake until the cake is golden and pulls away from the sides of the pan, about 35 minutes.
  • Transfer the pan to a wire rack and let cool.
  • Remove the cake from the pan and dust with more confectioners sugar.
  • (The cake can be made 1 day ahead.
  • Store airtight in a plastic container.)
  • Cut the cake into wedges and serve.
