Ingredients

1 cup unsalted butter, room temperature
1/3 cup vegetable oil
1-3/4 cups sugar
3 large eggs, room temperature
3 large egg whites, room temperature
1 tablespoon vanilla extract
3 cups cake flour
2 teaspoons baking powder
1 teaspoon salt
1 cup buttermilk, room temperature
1/4 cup rainbow sprinkles
1-1/2 cups unsalted butter, softened
4-1/2 cups confectioners' sugar, sifted
3 tablespoons heavy whipping cream
2 teaspoons clear vanilla extract

Directions

Preheat oven to 350°. In a large bowl, cream butter, oil and sugar until light and fluffy, about 5 minutes. Add eggs, then egg whites, 1 at a time, beating well after each addition. Beat in vanilla. In another bowl, whisk flour, baking powder and salt; add to creamed mixture alternately with buttermilk, beating well after each addition. Fold in sprinkles.
Transfer to a lightly greased 13x9-in. baking pan. Bake until a toothpick inserted in center comes out clean, 35-40 minutes. Cool completely on wire racks.
For buttercream, in a large bowl, beat butter until creamy. Gradually beat in confectioners’ sugar until smooth. Add cream, vanilla and food coloring. Beat until light and fluffy, 5-7 minutes. Frost top of cake with frosting and top with additional sprinkles if desired.
