Ingredients

For the Funfetti Cake

  • 2 ½ cups (315g) all-purpose flour
  • 2 ½ teaspoons baking powder
  • ½ teaspoon salt
  • 1 cup (225g) unsalted butter, softened
  • 1 ¾ cups (350g) granulated sugar
  • 4 large eggs
  • 1 tablespoon vanilla extract
  • 1 cup (240ml) milk
  • ¾ cup rainbow sprinkles (jimmies work best)

For the Chocolate Frosting

  • 1 cup (225g) unsalted butter, softened
  • 3 ½ cups (420g) powdered sugar
  • ½ cup (50g) unsweetened cocoa powder
  • ½ cup (120ml) heavy cream or milk
  • 1 teaspoon vanilla extract
  • Pinch of salt

How to Make Funfetti Layer Cake

Step 1: Prepare the Oven and Cake Pans

Preheat your oven to 350°F (175°C). Grease and line three round cake pans with parchment paper to prevent sticking and ensure easy removal after baking.

Step 2: Make the Cake Batter

In a medium bowl, whisk together the flour, baking powder, and salt.

In a separate large mixing bowl, beat the softened butter and sugar until the mixture becomes light and fluffy. Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.

Gradually add the dry ingredients and milk to the batter, alternating between the two and mixing until just combined. Gently fold in the rainbow sprinkles, being careful not to overmix, as the colors may bleed into the batter.

Step 3: Bake the Cake Layers

Divide the batter evenly among the prepared cake pans.

Bake for 25–30 minutes, or until a toothpick inserted into the center comes out clean. Remove the cakes from the oven and allow them to cool in the pans for several minutes before transferring them to a wire rack to cool completely.

Step 4: Prepare the Chocolate Frosting

In a large bowl, beat the softened butter until smooth and creamy.

Gradually add the cocoa powder and powdered sugar, mixing well after each addition. Pour in the heavy cream (or milk), add the vanilla extract and a pinch of salt, then continue beating until the frosting becomes light, fluffy, and easy to spread.

Step 5: Assemble the Cake

Place one cake layer on a serving plate or cake stand. Spread a generous layer of chocolate frosting over the top. Repeat with the remaining cake layers.

Once stacked, frost the top and sides of the cake. Smooth the frosting for a clean finish or create decorative swirls for a more festive look. Add extra rainbow sprinkles on top if desired.

Tips for the Best Funfetti Cake

  • Use jimmies-style sprinkles instead of nonpareils to prevent color bleeding.
  • Make sure all ingredients are at room temperature for a smoother batter.
  • Allow the cake layers to cool completely before frosting to avoid melting the frosting.
  • Store leftovers in an airtight container at room temperature for up to 2 days or refrigerate for up to 5 days.
