Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

2 ½ cups all-purpose flour
2 tsp baking powder
½ tsp salt
¾ cup butter, softened
1 ¾ cups granulated sugar
4 large eggs
1 tbsp vanilla extract
1 cup milk
½ cup rainbow sprinkles

For the chocolate frosting:
1 cup butter, softened
¾ cup cocoa powder
3 ½ cups powdered sugar
¼ cup milk
1 tsp vanilla extract

Directions

Preheat your oven to 350°F (175°C) and grease two round cake pans.

In a medium bowl, whisk together the flour, baking powder, and salt until evenly combined.

In a large bowl, beat the softened butter and sugar until the mixture becomes light and fluffy. Add the eggs one at a time, mixing well after each addition, then stir in the vanilla extract.

Gradually add the dry ingredients to the wet mixture, alternating with the milk. Begin and end with the dry ingredients, mixing just until combined. Gently fold in the rainbow sprinkles.

Divide the batter evenly between the prepared pans and smooth the tops. Bake for 28 to 32 minutes, or until a toothpick inserted in the center comes out clean. Allow the cakes to cool completely before frosting.

For the frosting, beat the butter until creamy. Add cocoa powder and mix until smooth. Gradually add powdered sugar, alternating with milk, and continue beating until the frosting is light and spreadable. Stir in the vanilla extract.

Assemble the cake by spreading frosting between the layers, then cover the top and sides. Finish by decorating with additional sprinkles.

Variations

Cupcake versions can also be made by adjusting the baking time to around 18–22 minutes.
