  • 3/4 cup (1 1/2 sticks) unsalted butter (softened to room temperature)
  • 1 cup granulated sugar
  • 2 eggs (room temperature)
  • 1 egg white (room temperature)
  • 1 1/2 tsp vanilla extract
  • 1/4 tsp almond extract
  • 1 1/2 cup cake flour
  • 1/2 cup all purpose flour
  • 1/2 tsp baking powder
  • 1/2 tsp baking soda
  • 1/2 tsp kosher sea salt
  • 3/4 cup +2 tbsp buttermilk (room temperature)
  • 1/2 cup rainbow jimmy sprinkles
  • 1 cup (2 sticks) butter (room temperature)
  • 1 1/2 tsp vanilla extract
  • pinch salt
  • 3 tbsp heavy cream
  • 3 1/2-4 cup powdered sugar
  • sprinkles for garnish

Instruction

  • Preheat oven to 350 degrees. Lightly butter and flour (or spray) a 9x13-inch pan.
  • Using a handheld or stand mixer fitted with a paddle attachment, beat the butter, sugar and extracts light and creamy, about 3-4 minutes. With mixing speed on low, add the eggs and egg white, beating after each addition.
  • In a medium mixing bowl, sift together the flours, baking powder, baking soda, and salt.
  • With mixing speed on low, alternate adding the dry ingredients with the buttermilk, taking care not to overmix. Using a rubber spatula, fold the sprinkles.
  • Pour the batter into the prepared cake pan, spreading into an even, smooth layer. Place in the oven and bake for 25-30 minutes or until the cake is golden brown on top and a cake tester inserted into the center comes out clean. Remove from the oven and allow to cool before frosting.
  • To prepare the frosting, in a large bowl using a hand-held mixer or stand mixer fitted with a whisk attachment, beat the butter until light and creamy, about 2 minutes. Add the vanilla, salt and powdered sugar, mix until large crumbs form, then slowly pour in the heavy cream. Gradually turn speed up to medium-high and beat for 2-3 minutes or until fluffy.
  • Scoop the frosting into the center of the cake, then using a offset spatula, spread over the cake into an even layer. Garnish with sprinkles if desired. Cut and serve, enjoy for up to 3 days at room temperature.
