# How to Make It:
01 - Preheat the oven to 350°F. Grease and line two 8-inch round cake pans with parchment paper and set aside.
02 - Whisk the all-purpose flour, baking powder, and salt together in a medium bowl until evenly distributed.
03 - In a large bowl, beat the softened butter and granulated sugar with an electric mixer until light and fluffy, about 3–4 minutes. Add the eggs one at a time, beating well after each addition, then mix in the vanilla.
04 - Alternately add the flour mixture and the milk to the butter mixture in three additions, beginning and ending with the flour. Mix gently until just combined; avoid overmixing.
05 - Fold the rainbow sprinkles into the batter with a spatula until evenly distributed. Divide the batter evenly between the prepared pans, smoothing the tops.
06 - Bake for 28–32 minutes, or until a toothpick inserted into the center comes out clean. Let the layers cool in the pans for 10 minutes, then invert onto a wire rack and cool completely.
07 - Beat the softened cream cheese and butter together until smooth. Gradually add the powdered sugar and continue beating until incorporated. Stir in the vanilla, then add 2 to 3 tablespoons of milk as needed to reach a spreadable consistency. Fold in the sprinkles and chill briefly to firm if necessary.
08 - Place one cake layer on a serving platter and spread a thick layer of the funfetti filling over it. Top with the second layer and use the remaining filling to frost the top and sides, smoothing with an offset spatula or knife.
09 - Press additional sprinkles and optional edible candies onto the frosted cake. Chill the assembled cake for at least 30 minutes to set before slicing.
