Ingredients

For the Cake

• 2½ cups (315 g) all-purpose flour
• 2½ teaspoons baking powder
• ½ teaspoon salt
• ¾ cup (170 g) unsalted butter, softened
• 1½ cups (300 g) granulated sugar
• 4 large eggs, room temperature
• 1 tablespoon vanilla extract
• 1 cup (240 ml) whole milk
• ½ cup (90 g) rainbow jimmies sprinkles (avoid nonpareils)

Vanilla Buttercream Frosting

• 1 cup (225 g) unsalted butter, softened
• 4 cups (480 g) powdered sugar
• 2–3 tablespoons heavy cream or milk
• 2 teaspoons vanilla extract
• Pinch of salt

Decoration

• Extra rainbow sprinkles
• Whipped cream (optional)

Instructions

1. Preheat the oven to 350°F (175°C). Grease and line two 8-inch (20 cm) round cake pans with parchment paper.
2. In a medium bowl, whisk together the flour, baking powder, and salt.
3. In a large bowl, beat the butter and sugar until light and fluffy, about 3–4 minutes.
4. Add the eggs one at a time, beating well after each addition. Mix in the vanilla.
5. Add the dry ingredients in three additions, alternating with the milk, beginning and ending with the flour mixture. Mix just until combined.
6. Gently fold in the rainbow sprinkles with a spatula.
7. Divide the batter evenly between the prepared pans.
8. Bake for 28–32 minutes, or until a toothpick inserted into the center comes out clean.
9. Let the cakes cool in the pans for 10 minutes, then transfer to a wire rack to cool completely.
10. For the frosting, beat the butter until creamy. Gradually add the powdered sugar, then mix in the vanilla, salt, and enough cream to achieve a smooth, spreadable consistency.
11. Frost the cooled cakes and decorate generously with extra sprinkles.

Tips

• Use rainbow jimmies sprinkles rather than nonpareils, as they hold their color better during baking.
• Avoid overmixing the batter after adding the sprinkles to prevent color bleeding.
• Bring all refrigerated ingredients to room temperature for a lighter, more even-textured cake.
• Store the frosted cake covered at room temperature for up to 2 days or refrigerate for up to 5 days. Let it come to room temperature before serving for the best flavor and texture.
