Ingredients

Scale

Cake Batter

  • 1 cup (220g) unsalted butter, room temperature
  • 2 cups (400g) granulated sugar
  • 1/2 cup (110ml) vegetable or canola oil
  • 4 large eggs, room temperature
  • 1 tbsp vanilla extract
  • 3 1/4 cups (435g) all-purpose flour
  • 2 1/2 tsp baking powder
  • 1/2 tsp baking soda
  • 1 tsp salt
  • 1/2 cup (125g) full fat sour cream, room temperature
  • 1 cup (225ml) buttermilk, room temperature
  • 3/4 cup (140g) rainbow jimmies sprinkles

Buttercream Frosting

  • 1 1/2 cups (330g) unsalted butter, room temperature
  • 5 cups (600g) powdered sugar
  • 1 tbsp vanilla extract
  • 2–3 tbsp milk
  • 1/2 cup (90g) sprinkles for decorating

Instructions

  1. Prep Oven and Pans: Preheat your oven to 350°F (177°C). Grease and line the bottoms of three 9-inch cake pans with parchment paper. Use cake strips on pans if available. If using 8-inch pans, reduce batter by about 1 cup to avoid overflow.
  2. Mix Dry Ingredients: Whisk together the all-purpose flour, baking powder, baking soda, and salt in a bowl; set aside for later use.
  3. Cream Butter and Sugar: Using a stand or hand mixer with a whisk attachment, beat the unsalted butter and granulated sugar on medium-high speed for 3-5 minutes until the mixture is light and fluffy.
  4. Add Oil: Turn the mixer to low speed and slowly pour in the vegetable or canola oil, then scrape down the sides and mix again briefly to combine.
  5. Add Eggs and Vanilla: Add eggs one at a time, mixing well after each addition, scraping down the bowl every two eggs. Then mix in the vanilla extract.
  6. Incorporate Sour Cream: Mix in the full fat sour cream to the batter until smoothly blended.
  7. Alternate Dry and Wet Ingredients: Add the dry ingredients and buttermilk alternately to the batter, starting and ending with the dry ingredients (dry, wet, dry, wet, dry). Mix until just combined.
  8. Fold in Sprinkles: Remove the bowl from the mixer and gently fold in the 3/4 cup of rainbow jimmies sprinkles using a rubber spatula to prevent the colors from bleeding.
  9. Fill and Bake: Pour the batter evenly into the prepared cake pans, filling them just over halfway. Bake 9-inch pans for 30-35 minutes or 8-inch pans for 35-40 minutes, until a toothpick inserted in the center comes out clean.
  10. Cool Cakes: Let the cakes cool in the pans for 30 minutes. Run a knife around the edges, invert the cakes onto a wire rack, and peel off the parchment paper. Chill in the refrigerator for about 1 hour before frosting or wrap and refrigerate overnight if preparing ahead.
  11. Make Buttercream: With a mixer and whisk attachment, beat the softened butter until smooth. Gradually add powdered sugar, one cup at a time, mixing well. Add vanilla extract and milk as needed to reach a smooth, spreadable consistency. Add extra milk if buttercream is too thick.
  12. Assemble Cake: Level the chilled cakes if necessary. Spread a thin layer of buttercream between layers. Apply a thin crumb coat around the entire cake and refrigerate for 20 minutes to set.
  13. Final Frosting and Decoration: Finish frosting the cake with the remaining buttercream, smoothing evenly. Decorate the top and sides with the remaining sprinkles. Serve and enjoy your festive Funfetti Cake!

Notes

  • Ensure all ingredients like eggs, sour cream, and buttermilk are at room temperature for best mixing results.
  • Use rainbow jimmies sprinkles rather than nonpareils to avoid color bleeding in the batter.
  • If you don’t have buttermilk, you can make a substitute by adding 1 tablespoon lemon juice or vinegar to 1 cup of milk and letting it sit for 5 minutes.
  • Filling the cake pans only halfway prevents the cakes from sinking in the middle.
  • Chilling the cakes thoroughly before assembling helps keep the buttercream from melting during application.
  • Store leftover cake covered in the refrigerator for up to 3 days.
