Ingredients

Scale
  • 2 cups (240g) all-purpose flour
  • 2 ½ teaspoons baking powder
  • ½ teaspoon baking soda
  • ½ teaspoon salt
  • ½ cup (115g) unsalted butter, softened
  • 1 ½ cups (300g) granulated sugar
  • 3 large eggs, room temperature
  • 2 teaspoons pure vanilla extract
  • 1 cup (240ml) whole milk, room temperature (can substitute almond or oat milk)
  • ¾ cup (about 120g) rainbow sprinkles, frozen
  • 8 oz (225g) cream cheese, softened
  • 3 cups (360g) powdered sugar
  • ½ cup (115g) unsalted butter for frosting, softened
  • 1 teaspoon pure vanilla extract for frosting

Instructions

  1. Preheat your oven to 350°F (175°C). Grease a 9×13-inch sheet pan lightly with butter or non-stick spray, then line it with parchment paper.
  2. In a medium bowl, whisk together flour, baking powder, baking soda, and salt.
  3. In a large bowl, beat softened butter and granulated sugar until light and fluffy, about 3–4 minutes on medium speed.
  4. Beat in eggs one at a time, mixing well after each addition, then stir in vanilla extract.
  5. With mixer on low, add dry ingredients in three parts alternating with milk, beginning and ending with flour mixture. Mix just until combined.
  6. Gently fold frozen sprinkles into the batter using a rubber spatula.
  7. Pour batter into the prepared pan and spread evenly.
  8. Bake for 30–35 minutes, checking at 30 minutes with a toothpick; it should come out clean or with a few moist crumbs.
  9. Cool cake in pan on wire rack for 20 minutes, then lift out using parchment paper and cool completely before frosting.
  10. Beat cream cheese and softened butter together until smooth and creamy, about 2–3 minutes.
  11. Gradually add powdered sugar and vanilla extract, beating on low until combined, then whip on medium speed until light and fluffy.
  12. Spread frosting evenly over cooled cake and optionally sprinkle additional rainbow sprinkles on top.
  13. Slice into squares and serve.

Notes

Freeze sprinkles before folding into batter to prevent color bleeding. Use room temperature ingredients for best texture. Frost only when cake is completely cool to avoid melting. If frosting is too soft, chill for 10 minutes before spreading. Use a sharp knife warmed under hot water for clean slicing.
