Description
There’s nothing quite as joyful as a Funfetti cake recipe. Originating in the 1980s as a boxed mix, this iconic dessert has become a symbol of celebration. Our homemade version skips the preservatives and delivers a richer flavor and texture. The secret? Real butter, buttermilk for moisture, and jimmies (long shaped sprinkles) that won’t bleed color into the batter.
Why This Recipe Works
- Moist crumb: Buttermilk and butter ensure a tender, fluffy cake.
- Sprinkle perfection: Jimmies stay vibrant and don’t dissolve.
- Easy frosting: A simple vanilla buttercream holds its shape and pairs perfectly with the cake.
Key Ingredients & Substitutions
- Buttermilk: Substitute with 1 cup milk + 1 tbsp lemon juice or vinegar.
- Sprinkles: Use jimmies, not nonpareils (tiny round sprinkles), to prevent color bleeding.
- Vanilla extract: Opt for pure vanilla for the best flavor.
Customization Ideas
- Cupcakes: Bake for 18–20 minutes for Funfetti cupcakes.
- Layers: Double the recipe for a 4 layer cake.
- Flavor twists: Add almond extract or lemon zest to the batter.

FAQs
- Can I freeze this cake? Yes! Wrap unfrosted layers tightly for up to 3 months.
- Why did my sprinkles sink? Toss them in flour before folding into the batter.
