Instructions

Preheat the oven to 350°F. Grease and flour a 9×13-inch baking pan.
In a medium bowl, whisk together the flour, baking powder, and salt. Set aside.
In a large bowl, beat the melted butter and sugar on medium speed until smooth. Add the eggs one at a time, then mix in the vanilla extract.
Alternately add the buttermilk and dry ingredients to the butter mixture, mixing on medium-high speed. Start and end with the buttermilk, scraping the bowl as needed. Stir in the rainbow sprinkles.
Pour the batter into the prepared pan. Bake for 30-40 minutes, or until a toothpick inserted into the center comes out clean. Let the cake cool completely before frosting.
For the frosting, beat the softened butter until creamy. Gradually add the powdered sugar, one cup at a time, until a crumbly mixture forms. Mix in the vanilla and salt, then add 2 tablespoons of heavy cream, mixing until smooth. Adjust the consistency by adding more cream if needed. Stir in sprinkles.
Frost the cooled cake and sprinkle more decorations on top. Frost using an offset spatula for best results. Store the cake loosely covered for up to 2 days.

Notes

Ensure all ingredients are at room temperature for best mixing results.
