How to Make Funfetti Layer Cake
Step 1: Prepare the Pans
Preheat your oven to 350°F (175°C). Grease and line three 8-inch cake pans with parchment paper.
Step 2: Mix the Dry Ingredients
- In a large bowl, whisk together:
- Flour
- Baking powder
- Baking soda
- Salt
- Set aside.
Step 3: Cream Butter and Sugar
In a stand mixer, beat butter and sugar for 3 to 4 minutes until pale and fluffy. This step creates a lighter cake texture and helps build volume.
Step 4: Add Egg Whites and Flavoring
- Mix in egg whites one at a time.
- Add:
- Vanilla extract
- Almond extract
- The almond extract gives that classic bakery-style birthday cake flavor.
Step 5: Combine Wet and Dry Ingredients
Add dry ingredients in three additions alternating with buttermilk. Fold in sour cream gently. Finally, fold in rainbow sprinkles carefully to avoid color streaks.
Baking the Cake Layers
Divide batter evenly between pans. Bake for 25 to 30 minutes or until a toothpick inserted in the center comes out clean. Allow cakes to cool completely before frosting. Professional bakers recommend cooling layers fully to prevent melting frosting and sliding layers.
How to Make Cake Batter Frosting
Step 1: Beat the Butter

Step 2: Add Sugar Gradually

Step 3: Add Flavor
