Ingredients

Scale
  • 2 1/2 cups all-purpose flour
  • 2 1/2 tsp baking powder
  • 1/2 tsp baking soda
  • 1/2 tsp salt
  • 1 cup unsalted butter, softened
  • 1 3/4 cups granulated sugar
  • 4 large eggs
  • 1 tbsp vanilla extract
  • 1 cup whole milk
  • 1/2 cup sour cream
  • 3/4 cup rainbow sprinkles (jimmies type)
  • For Frosting: 1 cup unsalted butter, softened
  • 4 cups powdered sugar
  • 23 tbsp heavy cream or milk
  • 1 tsp vanilla extract
  • Pinch of salt
  • Extra sprinkles for decoration

Instructions

  1. Preheat the oven to 350°F (175°C). Grease and flour two 9-inch round cake pans or line with parchment paper.
  2. In a medium bowl, whisk together flour, baking powder, baking soda, and salt. Set aside.
  3. In a large bowl, beat butter and sugar until light and fluffy, about 3-4 minutes.
  4. Add eggs one at a time, mixing well after each addition. Stir in vanilla extract.
  5. Mix in sour cream, then alternate adding the flour mixture and milk, starting and ending with the flour mixture. Mix until just combined.
  6. Gently fold in the sprinkles using a spatula.
  7. Divide the batter evenly between the prepared pans and smooth the tops.
  8. Bake for 25-30 minutes or until a toothpick inserted into the center comes out clean.
  9. Cool cakes in pans for 10 minutes, then turn out onto wire racks to cool completely.
  10. For the frosting, beat butter until creamy. Gradually add powdered sugar, then mix in vanilla and heavy cream until desired consistency is reached. Add a pinch of salt to balance sweetness.
  11. Frost the cooled cakes, stack them, and decorate the top and sides with extra sprinkles.

Notes

  • Use jimmies-type sprinkles to prevent color bleeding in the batter.
  • Make sure ingredients are at room temperature for even mixing.
  • Do not overmix after adding the sprinkles to avoid streaks of color.
