Ingredients

Scale
  • 2 1/2 cups all-purpose flour
  • 1 tablespoon baking powder
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon fine sea salt
  • 1 cup unsalted butter, softened
  • 1 1/2 cups granulated sugar
  • 4 large eggs, room temperature
  • 2 teaspoons pure vanilla extract
  • 1/2 cup sour cream
  • 1 cup whole milk, room temperature
  • 3/4 cup rainbow sprinkles (jimmies)
  • For the Sprinkle Frosting:
  • 1 cup unsalted butter, softened
  • 4 cups powdered sugar, sifted
  • 1/4 cup whole milk or heavy cream
  • 2 teaspoons pure vanilla extract
  • 1/4 teaspoon salt
  • 1/2 cup rainbow sprinkles (jimmies)
  • Optional Garnishes:
  • Extra rainbow sprinkles
  • Birthday candles or fun toppers

Instructions

  1. Preheat oven to 350°F (175°C). Grease two 9-inch round cake pans and line bottoms with parchment paper. Lightly dust sides with flour.
  2. In a medium bowl, whisk together flour, baking powder, baking soda, and salt. Set aside.
  3. In a large bowl, beat softened butter with sugar on medium-high until light and fluffy, about 3-4 minutes.
  4. Beat in eggs one at a time, mixing well after each. Add vanilla extract and mix until combined.
  5. In a small bowl, whisk together sour cream and milk until smooth.
  6. With mixer on low, add dry ingredients to butter mixture in three parts, alternating with sour cream mixture. Start and end with dry ingredients. Mix just until combined.
  7. Gently fold in rainbow sprinkles with a spatula.
  8. Divide batter evenly between prepared pans and smooth tops. Bake for 25-30 minutes, or until a toothpick inserted in center comes out clean.
  9. Let cakes cool in pans for 10 minutes, then turn out onto wire rack to cool completely.
  10. For the frosting: In a large bowl, beat butter on high until creamy, about 2 minutes. Gradually add powdered sugar, salt, and vanilla. Add milk or cream slowly, beating until light and spreadable. Fold in sprinkles at the end.
  11. Place one cake layer on serving plate. Spread about 1 cup frosting over top. Add second layer and cover cake with remaining frosting, swirling for decoration. Decorate with extra sprinkles and candles as desired.

Notes

Use jimmies for best sprinkle results; nonpareils may bleed. Room temperature ingredients yield a fluffier cake. For gluten-free or dairy-free, substitute flour and dairy as needed. Chill frosting if too soft before spreading. Cake layers can be made ahead and chilled for easier frosting.
