Ingredients

Scale
  • 2 ยฝ cups (315g) all-purpose flour
  • 2 ยฝ teaspoons baking powder
  • ยฝ teaspoon salt
  • 1 cup (227g) unsalted butter, softened
  • 1 ยพ cups (350g) granulated sugar
  • 4 large eggs, room temperature
  • 1 tablespoon pure vanilla extract
  • 1 cup (240ml) whole milk, room temperature
  • ยพ cup (130g) rainbow sprinkles
  • 8 oz (225g) cream cheese, softened
  • ยฝ cup (113g) unsalted butter, softened
  • 4 cups (480g) powdered sugar, sifted
  • 1 teaspoon pure vanilla extract
  • Pinch of salt

Instructions

  1. Preheat oven to 350ยฐF (175ยฐC). Lightly grease a 9×13 inch sheet cake pan and line with parchment paper.
  2. In a medium bowl, whisk together flour, baking powder, and salt. Set aside.
  3. In a large bowl, beat softened butter and sugar until light and fluffy, about 4-5 minutes on medium speed.
  4. Beat in eggs one at a time, mixing well after each addition. Stir in vanilla extract.
  5. Reduce mixer speed to low. Add dry ingredients in three parts, alternating with milk in two parts, beginning and ending with dry ingredients. Mix each addition just until combined.
  6. Gently fold in rainbow sprinkles using a rubber spatula, being careful not to overmix.
  7. Pour batter evenly into prepared pan and smooth the top. Bake for 35-40 minutes or until a toothpick inserted in the center comes out clean.
  8. Let cake cool in pan for 15 minutes, then transfer to a wire rack to cool completely.
  9. Beat cream cheese and softened butter until smooth. Gradually add powdered sugar, vanilla extract, and salt. Beat until fluffy and spreadable.
  10. Spread cream cheese frosting evenly over cooled cake. Optionally, sprinkle additional rainbow sprinkles on top. Chill briefly if needed for easier slicing.

Notes

Use room temperature ingredients for best results. Use high-quality non-melting sprinkles to prevent color bleeding. Chill frosting if too soft before spreading. Store frosted cake covered in the fridge for up to 4 days. For dairy-free or gluten-free versions, substitute ingredients accordingly.
