  • 2½ cups (500 g) sugar
  • 1 tbsp baking powder
  • ½ tsp baking soda
  • 1 tsp salt
  • 1½ cups (340 g) unsalted butter, softened
  • 6 large egg whites
    (or 3 whole eggs + 3 egg whites)
  • 1½ cups (360 ml) milk, room temperature
  • ½ cup (120 ml) vegetable oil
  • 2 tbsp vanilla extract
  • ⅔ cup (120 g) rainbow sprinkles (jimmies type, not nonpareils)

Whipped Vanilla Buttercream

  • 2 cups (452 g) unsalted butter, softened
  • 6 cups (720 g) powdered sugar
  • 6 tbsp (90 ml) milk or heavy cream
  • 2 tsp vanilla extract
  • A pinch of salt

Instructions

Make the Funfetti Cake

  • Preheat the oven to 170°C (340°F).
  • Grease and line six 6-inch cake pans with parchment paper circles.
  • In a large bowl, whisk together flour, sugar, baking powder, baking soda, and salt.
  • Add softened butter and mix until the texture resembles soft crumbs.
  • In another bowl, combine milk, vegetable oil, egg whites, and vanilla extract.
  • Pour the wet ingredients into the dry ingredients and beat until smooth and creamy.
  • Gently fold in the rainbow sprinkles to avoid color bleeding.
  • Divide the batter evenly among the prepared cake pans.
  • Bake for 18–22 minutes or until the cakes spring back lightly when touched.
  • Let the cake layers cool completely before assembling.

Make the Whipped Vanilla Buttercream

  • Beat the softened butter until pale, fluffy, and creamy.
  • Gradually add powdered sugar while mixing continuously.
  • Pour in milk or heavy cream and vanilla extract.
  • Whip until the buttercream becomes light, smooth, and airy.
  • Add a pinch of salt to balance the sweetness.

Assemble the 6 Layers

  • Level the tops of the cake layers if needed.
  • Place the first cake layer onto a cake board or stand.
  • Spread a thin layer of buttercream evenly over the top.
  • Repeat with all remaining layers until all six are stacked.
  • Apply a thin crumb coat over the entire cake and chill for 20 minutes.
  • Finish with a final smooth layer of buttercream frosting.
  • Decorate with rainbow sprinkles around the base and top for a fun party look.

Tips for the Perfect Funfetti Cake

  • Use jimmies-style sprinkles because nonpareils can bleed color into the batter.
  • Room temperature ingredients create a smoother batter and softer cake texture.
  • Chill the cake before final frosting for cleaner layers.
  • Avoid overmixing once the sprinkles are added.

This colorful Funfetti Cake is soft, buttery, and perfect for birthdays, parties, and special celebrations.
