Instructions

Preheat oven to 350°F. Grease and flour a 9×13-inch baking pan.
Whisk together flour, baking powder, and salt in a medium bowl. Set aside.
In a large bowl, mix melted butter and granulated sugar on medium speed until smooth. Gradually mix in the eggs, one at a time, then add the vanilla extract.
Alternately add the buttermilk and dry ingredients to the mixture, starting and ending with buttermilk. Mix just until combined, scraping the bowl as needed. Stir in the rainbow sprinkles.
Pour the batter into the prepared baking pan. Bake for 30-40 minutes or until a toothpick inserted comes out clean. Let it cool completely before frosting.
For the frosting: Beat softened butter until creamy. Gradually add powdered sugar, mixing until crumbly. Add vanilla and salt, then mix in 2 tablespoons of heavy cream until smooth, adding more cream as desired. Stir in additional sprinkles.
Frost the cooled cake and top with more sprinkles. Use an offset spatula for easy frosting. Store loosely covered for up to 2 days.
This recipe can also be used to make 24 cupcakes, two 9-inch round cakes, or three 8-inch round cakes.

Notes

Ensure the butter is at the right consistency for the frosting by beating until creamy but not overly melted.
For a fun twist, use themed sprinkles to match events or holidays.
Make ahead by baking the cake and freezing it before frosting; thaw before serving.
