Ingredients

  • 1 cup unsalted butter, softened to 68°F
  • 1 cup granulated sugar
  • 1 large egg
  • 1 large egg yolk
  • 1 teaspoon pure vanilla extract
  • 2 cups all-purpose flour
  • 1 teaspoon baking powder
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 tablespoon cornstarch
  • 1/2 cup rainbow sprinkles (jimmies)
  • 1/2 cup white chocolate chips
  • 1/2 cup butter, softened (for frosting)
  • 2 cups confectioners’ sugar
  • 2 tablespoons heavy cream
  • 1/2 teaspoon almond extract


Instructions

  1. Cream the butter. Using a stand mixer with a paddle attachment, beat the softened butter for 60 seconds until smooth, then add granulated sugar and cream for 3 minutes until light and fluffy.
  2. Mix in liquids. Add the egg, egg yolk, and vanilla extract, beating on medium speed until the mixture forms a glossy, stable emulsion.
  3. Combine dry ingredients. Whisk flour, salt, baking powder, baking soda, and cornstarch, then add to the wet ingredients in three additions on low speed until just incorporated.
  4. Fold in extras. Gently fold in white chocolate chips and rainbow sprinkles using a silicone spatula to avoid damaging the ingredients.
  5. Prepare and bake. Press the dough into a greased 9-inch round pan and bake at 350°F for 25 to 30 minutes, ensuring the edges are golden while the center remains slightly soft.
  6. Cool the cake. Allow the cake to cool completely in the pan for at least 90 minutes to let the crumb set properly.
  7. Frost and decorate. Whip the remaining butter, confectioners’ sugar, cream, vanilla, and almond extract, then pipe rosettes around the perimeter and top with extra sprinkles.

Notes

  • Use a kitchen scale for flour measurements to ensure the perfect chewy consistency.
  • Always select wax-coated jimmies for sprinkles to prevent the colors from bleeding into the dough.
  • Allow the cake to cool fully before decorating to ensure the buttercream maintains its structure.
  • For professional slices, chill the finished cake for 30 minutes and use a warm, dry knife.
