Ingredients

Scale

Dry Ingredients

  • 2 1/2 cups (300 grams) all-purpose flour
  • 1/4 cup (28 grams) cornstarch
  • 2 teaspoons baking powder
  • 1 1/2 teaspoons salt

Wet Ingredients

  • 16 tablespoons (8 ounces / 226 grams) unsalted butter, at room temperature
  • 1 1/2 cup (300 grams) granulated sugar
  • 1 tablespoon pure vanilla extract
  • 4 large eggs plus 1 large egg yolk, at room temperature
  • 1 1/2 cups (340 grams) buttermilk, at room temperature

Additional Ingredients

  • 1 cup rainbow sprinkles (jimmies)
  • Classic American Buttercream (for frosting)
  • Optional frostings: Italian Meringue Buttercream or White Chocolate Ganache Buttercream

Instructions

  1. Prep the pans: Preheat your oven to 350°F (176°C). Grease and flour three 8 or 9-inch round cake pans, then line the bottoms with parchment paper coated lightly with butter or shortening to ensure easy cake release. For cupcakes, line the pans with paper liners; this recipe yields about 30 cupcakes.
  2. Mix dry ingredients: In a medium bowl, whisk together the flour, cornstarch, baking powder, and salt until well combined, ensuring even distribution of the leavening agents.
  3. Cream butter and sugar: In the bowl of an electric mixer, beat the softened butter and granulated sugar on medium-high speed for about 5 minutes until fluffy and pale in color. Add the vanilla extract and mix until fully incorporated.
  4. Add eggs gradually: Scrape down the bowl sides. Add two eggs and beat on high until fully incorporated. Scrape down again, then add the remaining two eggs plus the egg yolk, beating on high until the batter is completely smooth and uniform.
  5. Alternate dry and wet additions: With the mixer on low speed, add the flour mixture and buttermilk alternately in this order: 1/4 of the flour, 1/3 of the buttermilk, 1/4 flour, 1/3 buttermilk, 1/4 flour, remaining buttermilk, then the last of the flour. Mix just until each addition is incorporated, stopping to scrape the sides as needed to avoid overmixing.
  6. Fold in sprinkles: Using a rubber spatula or wooden spoon, gently fold the rainbow sprinkles into the batter just until evenly distributed, taking care not to color the batter.
  7. Portion batter: Evenly divide the batter into the prepared cake pans or cupcake liners to ensure consistent baking. Smooth the tops lightly with a spatula if needed.
  8. Bake: Place in the preheated oven. Bake cake layers for 33 to 38 minutes, or cupcakes for 23 to 26 minutes. Test doneness by inserting a toothpick into the center; if it comes out with only moist crumbs, the cake is done.
  9. Cool: Remove pans from the oven and set on wire racks. Let cake layers cool for 5 minutes in the pans, then carefully invert them onto wire racks to cool completely. Remove cupcakes and place on racks. Once cooled, wrap layers tightly with plastic wrap or store cupcakes in airtight containers. Cakes can be kept at room temperature for one day or frozen up to two months.

Notes

  • For cupcakes, use paper liners and bake for 23-26 minutes, yielding about 30 cupcakes.
  • Ensure all ingredients, especially eggs, butter, and buttermilk, are at room temperature for optimal mixing and batter texture.
  • Do not overmix the batter once the flour and buttermilk are added to avoid a dense cake.
  • Gently fold sprinkles in to prevent the batter from turning color.
  • Store baked cake layers wrapped tightly or cupcakes in airtight containers to maintain freshness.
