Recipe Information
Ingredients
- 3 cups all-purpose flour
- 2.5 teaspoons baking powder
- 0.5 teaspoons salt
- 1 cup unsalted butter (room temperature)
- 2 cups granulated sugar
- 4 pieces large eggs
- 1.5 tablespoons vanilla extract
- 1 cup whole milk
- 0.75 cup rainbow sprinkles
- 4 cups powdered sugar
- 1.5 cups unsalted butter (softened, for frosting)
- 1 teaspoon vanilla extract (for frosting)
- 4 tablespoons heavy cream or milk (for frosting)
- as needed gel food coloring (optional)
- 8 pieces birthday candles (8 candles)
Instructions
Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans and set them aside.
In a medium bowl, whisk together the all-purpose flour, baking powder, and salt. Set aside.
In a large mixing bowl, beat the room-temperature unsalted butter and granulated sugar together using an electric mixer until light and fluffy, about 3-4 minutes.
Add the eggs one at a time to the butter and sugar mixture, mixing well after each addition. Stir in the vanilla extract.
Alternately add the flour mixture and the milk into the wet ingredients, beginning and ending with the flour mixture (3 additions of flour, 2 additions of milk). Mix at low speed until just combined.
Gently fold in the rainbow sprinkles with a spatula, being careful not to overmix to avoid the colors bleeding into the batter.
Divide the batter evenly between the prepared cake pans. Smooth the tops with a spatula.
Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean. Remove the cakes from the oven and let them cool in the pans for 10 minutes before transferring them to wire racks to cool completely.
While the cakes cool, prepare the frosting. In a large bowl, beat the softened butter until creamy. Gradually add the powdered sugar, one cup at a time, mixing well after each addition.
Stir in the vanilla extract and 2 tablespoons of heavy cream or milk. Beat on high speed for about 2-3 minutes until the frosting is fluffy. If needed, adjust the consistency with additional heavy cream/milk or powdered sugar.
If desired, divide the frosting into separate bowls and mix in gel food coloring to create different colors for decorating.
Once the cakes are completely cooled, level the tops if necessary using a serrated knife. Place one cake layer on a serving plate or cake board and spread a layer of frosting on top.
Place the second cake layer on top and frost the outside and sides of the cake evenly. Decorate with additional sprinkles and pipe decorative frosting if desired.
Top the cake with 8 birthday candles. Light the candles just before serving and enjoy the celebration!
