Tips and Tricks for Baking the Perfect Funfetti Fun Time Cake

Soft & Moist Funfetti Cake | Butternut Bakery

  • Quality Sprinkles: Use high-quality rainbow sprinkles that are vibrant and won’t bleed their colors into the batter while baking.
  • Even Distribution: Toss the sprinkles with a bit of flour before folding them into the batter. This helps prevent them from sinking to the bottom.
  • Room Temperature Ingredients: Ensure all dairy, eggs, and butter are at room temperature. This promotes even mixing and a smoother batter.
  • Gentle Mixing: When incorporating the sprinkles, fold them into the batter gently to avoid overmixing and maintaining the vibrant colors.
  • Cake Strips: Use cake strips around the cake pans to ensure even baking and to prevent doming.
  • Cooling Time: Allow the cake layers to cool in the pans for about 10 minutes before transferring them to a wire rack. This prevents them from sticking.
  • Leveling the Layers: To ensure your cake stacks evenly, level the tops of the cooled cake layers using a serrated knife or a cake leveler.
  • Crumb Coat: Apply a thin layer of frosting, known as a crumb coat, before the final layer. This helps to lock in any loose crumbs and create a smooth finish.
  • Chilling Time: After applying the crumb coat, chill the cake in the refrigerator for about 20-30 minutes. This makes it easier to apply the final layer of frosting.
  • Frosting Techniques: Use an offset spatula for a smooth finish or experiment with piping techniques for a more decorative look.
  • Sprinkle Garnish: Decorate the frosted cake with an extra sprinkle of rainbow goodness for a pop of color and whimsy.
  • Sharp Slices: For clean and neat slices, use a sharp knife dipped in warm water. Wipe the knife between each cut for a polished presentation.
  • Room Temperature Serving: Before serving, allow the cake to come to room temperature for the best flavor and texture.
  • Storing Leftovers: Store any leftover cake in an airtight container in the refrigerator. For longer storage, consider freezing individual slices wrapped tightly in plastic wrap and then placed in an airtight container.
