Ingredients Method Notes

Ingredients
  

  • 2 ½ cups all-purpose flour
  • 2 ½ tsp baking powder
  • ½ tsp fine sea salt
  • 1 cup unsalted butter, softened
  • 2 cups granulated sugar
  • 4 large eggs, room temperature
  • 1 tbsp pure vanilla extract
  • 1 cup buttermilk, room temperature
  • ½ cup rainbow sprinkles (jimmies)
  • 1 ½ cups powdered sugar
  • 2 to 3 tbsp milk
  • ½ tsp vanilla extract
  • Extra sprinkles for topping

Method
 

  1. Cream the butter and sugar until fluffy, then beat in eggs and vanilla. Alternate adding the dry ingredients and buttermilk, mixing just until smooth.
  2. Gently fold in the sprinkles with a spatula, being careful not to overmix.
  3. Pour the batter into a greased 10-cup Bundt pan and bake at 350°F for 40 to 45 minutes, until a toothpick comes out clean. Cool in the pan for 10 minutes, then invert onto a rack to cool completely.
  4. Whisk together the glaze ingredients until smooth. Drizzle over the fully cooled cake and top with additional sprinkles.

Notes

Room temperature ingredients really do make a difference here, cold eggs or buttermilk can lead to a dense cake. If the sprinkles start to bleed color while folding, stop immediately and pour the batter into the pan. Cool the cake all the way before glazing or the sugar will melt into a puddle.
