  • Total Time: 2 hours 55 minutes
  • Yield: 15 servings

Ingredients

Dry Ingredients

  • 2 1/3 cups unbleached cake flour
  • 1 1/2 cups granulated sugar
  • 1 tablespoon baking powder
  • 1 tablespoon vanilla powder
  • 1 teaspoon fine sea salt

Wet Ingredients for Cake Batter

  • 12 tablespoons cubed unsalted butter (room temperature)
  • 3 large eggs (room temperature)
  • 1/2 cup whole milk (room temperature)
  • 1/2 cup heavy cream (room temperature)
  • 1/2 cup sour cream (room temperature)
  • 1/4 cup vegetable oil
  • 1 tablespoon imitation vanilla (or real vanilla)
  • 1/3 cup rainbow jimmies sprinkles

Buttercream Frosting

  • 1 cup salted butter (room temperature)
  • 1 1/2 cups unsalted butter (room temperature)
  • 4 cups powdered sugar
  • 3 tablespoons heavy cream
  • 2 teaspoons pure vanilla bean paste or extract

Instructions

  1. Prepare the Cake Pans: Preheat your oven to 325°F (160°C). Grease and flour the sides of three 8-inch cake pans and line the bottoms with parchment paper to prevent sticking. Set them aside.
  2. Mix Dry Ingredients: In a stand mixer bowl, whisk together the cake flour, granulated sugar, baking powder, vanilla powder, and fine sea salt until well combined.
  3. Cream Butter into Dry Mix: On low speed, incorporate the cubed unsalted butter into the dry ingredients until the mixture reaches a sandy texture, about 2 to 3 minutes. This helps distribute the fat evenly.
  4. Combine Wet Ingredients: In a separate bowl, whisk together eggs, whole milk, heavy cream, sour cream, vegetable oil, and imitation vanilla until smooth and homogeneous.
  5. Add Wet Ingredients to Dry: Add half of the wet mixture into the dry mixture and mix until all the flour is moistened. Scrape down the sides of the bowl to ensure even mixing.
  6. Finish Mixing Batter: Add the remaining wet ingredients plus the rainbow sprinkles on low speed and mix just until combined. Avoid overmixing to keep the batter light.
  7. Distribute Batter and Bake: Evenly divide the batter into the prepared pans (approximately 475 grams each). Bake for 25 to 30 minutes, or until the edges turn golden brown and a toothpick inserted in the center comes out with a few moist crumbs.
  8. Cool Cakes: Allow the cakes to cool in the pans on wire racks for 20 to 30 minutes. Then remove from pans and let them cool completely on the racks.
  9. Prepare Frosting Butter: Using a stand mixer or hand mixer, beat the salted and unsalted butter together on medium speed for 2 to 3 minutes until the mixture is light and fluffy.
  10. Add Sugar to Frosting: Gradually add the powdered sugar, pulsing at first to avoid a sugar cloud, then mix at medium speed for 4 to 5 minutes until the frosting is light, white, and fluffy.
  11. Add Cream and Vanilla: Mix in the heavy cream and vanilla bean paste or extract until just combined, resulting in a smooth and creamy frosting.
  12. Assemble Cake Layers: Place the first cooled cake layer onto your serving platter or cake stand. Apply an even layer of frosting on top. Repeat with the second layer and then place the final layer upside down to keep the top flat.
  13. Crumb Coat and Chill: Spread a thin layer of frosting over the entire assembled cake to seal in crumbs and refrigerate for 20 to 30 minutes to set the crumb coat.
  14. Final Frosting and Decoration: Apply the remaining frosting evenly over the cake. Use any leftover frosting to decorate as desired and garnish with additional rainbow sprinkles for a festive finish.
  15. Serve and Enjoy: Slice the cake and enjoy the colorful, flavorful funfetti layers with creamy buttercream.

Notes

  • Use unbleached cake flour for the lightest texture; if unavailable, you can make a substitute by replacing 2 tablespoons of all-purpose flour per cup with cornstarch.
  • Room temperature ingredients help create a smoother batter and better rise.
  • Imitation vanilla gives a classic box cake flavor, but real vanilla extract or bean paste will provide a more authentic taste.
  • Be careful not to overmix once sprinkles are added to prevent streaking colors.
  • Ensure the cake layers are completely cooled before frosting to prevent melting.
  • The cake layers bake very flat, so trimming is usually unnecessary.
  • For best results, refrigerate the frosted cake before the final decoration to achieve a smooth finish.
