Ingredients
For the Cake:
- 2 ½ cups all-purpose flour
- 2 ½ tsp baking powder
- ½ tsp baking soda
- ½ tsp salt
- 1 cup unsalted butter, softened
- 1 ¾ cups granulated sugar
- 4 large eggs
- 2 tsp vanilla extract
- 1 cup whole milk
- ½ cup rainbow sprinkles
For the Frosting:
- 1 cup unsalted butter, softened
- 4 cups powdered sugar
- 2–4 tbsp heavy cream
- 1 tsp vanilla extract
- Additional sprinkles for decoration

Preparation Steps
- Preheat Oven: Preheat your oven to 350°F (175°C). Grease and flour two 8-inch round cake pans or line them with parchment paper.
- Mix Dry Ingredients: In a bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.
- Cream Butter and Sugar: In a large mixing bowl, beat the softened butter and granulated sugar until light and fluffy (about 3 minutes).
- Add Eggs and Vanilla: Beat in the eggs, one at a time, followed by the vanilla extract.
- Combine Wet and Dry: Gradually mix the dry ingredients into the wet mixture, alternating with the milk, beginning and ending with the dry ingredients. Do not overmix.
- Fold in Sprinkles: Gently fold in the sprinkles, being careful not to overmix to prevent colors from bleeding.
- Bake: Divide the batter evenly between the prepared pans. Bake for 30-35 minutes or until a toothpick inserted in the center comes out clean. Let the cakes cool in the pans for 10 minutes before transferring to a wire rack to cool completely.
- Prepare Frosting: Beat butter until creamy. Gradually add powdered sugar, heavy cream, and vanilla extract. Mix until smooth and fluffy.
- Assemble the Cake: Spread a layer of frosting on top of one cake layer, place the second layer on top, and frost the entire cake. Decorate with additional sprinkles.
- Serve and Celebrate: Slice, serve, and enjoy!
