Ingredients

Cake

  • 2 & 1/2 cups (250g) cake flour, sifted
  • 1 & 1/2 tsp baking powder
  • 1/2 tsp baking soda
  • 1/4 tsp salt
  • 3/4 cup (170g) unsalted butter, room temperature
  • 1 & 1/2 cups (300g) granulated sugar
  • 2 large whole eggs, room temperature
  • 2 large egg whites, room temperature
  • 2 tsp vanilla extract
  • 1/4 cup (60g) sour cream, room temperature
  • 3/4 cup (188ml) milk, room temperature

Buttercream

  • 1 cup (227g) unsalted butter, room temperature
  • seeds of 1 vanilla bean or 2 tsp vanilla extract
  • 1/4 tsp salt
  • 4 cups (500g) powdered sugar
  • Sprinkles for decorating
  • 46 tbsp milk or cream

Instructions

Cake

  1. Preheat the oven to 350F degrees. Line a 9×13″ metal baking pan with parchment paper or grease and flour if using a glass or ceramic baking dish. Set aside.
  2. In a medium-sized bowl whisk together the flour, baking powder, baking soda, and salt. Set aside.
  3. Using an electric mixer or stand mixer with paddle attachment, beat the butter and sugar together until fluffy (about 2 minutes).
  4. Slowly beat in the eggs, one at a time, followed by the vanilla and sour cream.
  5. Stir in half of the flour mixture and mix in the milk.
  6. Then stir in the remaining flour mixture until just combined. Pour the batter into the prepared pan.
  7. Bake for 25-30 minutes or until an inserted toothpick comes out clean. Allow the cake to cool fully before frosting.

Frosting

  1. Beat the butter, salt, and vanilla until light and fluffy.
  2. Add in the powdered sugar, 1 cup at a time, mixing well in between. Add in the cream or milk, 1 tablespoon at a time as needed.
  3. Beat on high speed for about 1 minute after the last addition of powdered sugar for a fluffy and airy texture. Spread on cooled cake and decorate with sprinkles if desired.

Notes

Leftover cake can be covered and stored in the refrigerator for up to 5 days. Bring to room temperature by letting it sit out on the counter for 1 hour before serving.
