Ingredients

For the Funfetti 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
• 1 tbsp vanilla extract
• 1 cup buttermilk
• ½ cup sour cream
• ¾ cup rainbow sprinkles (jimmies, not nonpareils)

For the Buttercream Frosting:

• 1 cup unsalted butter, softened
• 4 cups powdered sugar
• 2 tsp vanilla extract
• 3 tbsp heavy cream or milk
• Pinch of salt
• Extra rainbow sprinkles for decoration

Instructions

Step 1: Preheat and Prepare Pans

Preheat the oven to 350°F (175°C). Grease and line two 9-inch round cake pans with parchment paper for easy removal.

Step 2: Mix Dry Ingredients

In a medium bowl, whisk together flour, baking powder, baking soda, and salt. Set aside.

Step 3: Cream Butter and Sugar

In a large mixing bowl, beat the butter and sugar with an electric mixer on medium speed until light and fluffy, about 2-3 minutes.

Step 4: Add Eggs and Vanilla

Add the eggs one at a time, beating well after each addition. Mix in the vanilla extract.

Step 5: Incorporate Wet and Dry Ingredients

Reduce the mixer speed to low. Alternate adding the dry ingredients and buttermilk, starting and ending with the dry ingredients. Mix until just combined. Stir in the sour cream to add extra moisture.

Step 6: Fold in Sprinkles

Gently fold in the rainbow sprinkles using a spatula, being careful not to overmix to prevent color bleeding.

Step 7: Bake the Cake

Divide the batter evenly between the prepared cake pans. Smooth the tops and bake for 30-35 minutes or until a toothpick inserted in the center comes out clean.

Step 8: Cool the Cake

Let the cakes cool in the pans for 10 minutes, then transfer them to a cooling rack to cool completely before frosting.

Step 9: Prepare the Buttercream Frosting

In a large mixing bowl, beat the butter until smooth and creamy. Gradually add powdered sugar, vanilla extract, and heavy cream, beating until fluffy.

Step 10: Assemble the Cake

Place one cake layer on a serving plate. Spread a layer of buttercream frosting on top. Place the second layer on top and frost the entire cake.

Step 11: Decorate and Serve

Decorate with extra sprinkles and smooth out the frosting with an offset spatula. Slice and serve!

Tips for Best Results

• Use Room Temperature Ingredients – This ensures a smooth batter and even baking.
• Don’t Overmix the Batter – Gently fold in the sprinkles to prevent color bleeding.
• Let the Cake Cool Completely – Frosting a warm cake can cause it to melt.
• Use Jimmies Sprinkles – Avoid nonpareils, as they can bleed color into the batter.

Pairing Suggestions

• Serve with a scoop of vanilla or strawberry ice cream.
• Pair with a glass of cold milk or a cup of coffee for adults.
