Ingredients:
- 1 cup (2 sticks or 226g) unsalted butter, room temperature
- 1/2 cup shortening
- 3 cups (600g) granulated sugar
- 5 large eggs, room temperature
- 2 teaspoons vanilla
- 3 cups (375g) all-purpose flour
- 2 teaspoons baking powder
- 1/4 teaspoon kosher salt
- 1 cup (245g) whole milk
- 1 1/2 cups rainbow jimmies (sprinkles)
Instructions:
- Preheat oven to 350º F. Prepare three 8-inch round cake pans with nonstick baking spray and line the pan with a parchment paper round. (Don’t skip this step)
- In the bowl of a stand mixer fitted with the paddle attachment, cream together butter and shortening until light and fluffy, about 2 minutes. Stop and scrape sides as needed.
- Slowly add sugar and make sure ingredients are fully incorporated.
- Add eggs one at a time, making sure to fully incorporate each egg before adding another. Add in vanilla.
- In a medium bowl, sift together flour, baking powder, and salt.
- Add flour mixture to butter and shortening mixture alternately with milk mixture, beginning and ending with dry ingredients.
- Remove bowl from stand mixer and stir in the rainbow jimmies by hand.
- Evenly distribute cake batter between cake pans (roughly 2 1/4 cups per pan) and place pans into oven. Bake for 25-30 minutes, or until a toothpick or cake tester inserted in the center comes out mostly clean.
- Cool in cake pans for about 10 minutes, then invert and cool completely on a wire rack.
