It’s not a real celebration without sprinkles. This homemade funfetti cake is soft, fluffy, buttery, and packed with colorful confetti in every bite. It tastes even better than the classic box mix — but still delivers all the nostalgia you remember.
Layered with silky vanilla buttercream and bursting with rainbow sprinkles, this cake is pure birthday magic. Whether you’re celebrating a milestone or just want an excuse to bake something joyful, this is the cake that turns any day into a party.
What Is Funfetti Cake?
Funfetti cake is essentially a vanilla cake with sprinkles folded into the batter. That’s it — but somehow, it feels like so much more.
The sprinkles melt slightly as the cake bakes, creating colorful bursts throughout a tender vanilla crumb. A touch of almond extract enhances the flavor, giving it that classic bakery-style birthday cake taste.
It’s simple. It’s nostalgic. It’s pure happiness in cake form.
Why This Funfetti Cake Is So Good
This isn’t just a vanilla cake with sprinkles tossed in. It’s been carefully balanced to be:
Moist and tender
Using both butter and oil gives you the best of both worlds: rich flavor from butter and unbeatable moisture from oil.
Perfectly sweet
Not overly sugary, just balanced and fluffy.
Full of real vanilla flavor
A generous amount of vanilla (plus a hint of almond extract) makes this cake taste like a bakery classic.
Easy to make
No complicated techniques — just straightforward mixing and baking.

How to Make Homemade Funfetti Cake
1. Prep Your Pans
Preheat the oven to 350°F. Line two 8-inch cake pans with parchment paper and grease the sides.
2. Cream the Butter, Oil & Sugar
Beat the butter and oil together until smooth. Gradually add sugar and beat until light, fluffy, and pale.
3. Add Eggs & Flavoring
Mix in the eggs, vanilla extract, and almond extract until airy and well combined.
4. Alternate Dry Ingredients & Buttermilk
Whisk together the flour, baking powder, and salt. With the mixer on low, alternate adding dry ingredients and buttermilk in stages. Mix just until combined — do not overmix.
5. Fold in Sprinkles
Gently fold in the sprinkles until evenly distributed.
6. Bake
Divide the batter evenly between pans and bake for 30–40 minutes, until the tops spring back and a knife inserted in the center comes out clean.
Cool completely before frosting.
The Dreamiest Vanilla Buttercream
No funfetti cake is complete without classic vanilla buttercream.
Beat softened butter until pale and fluffy. Gradually add powdered sugar and mix until smooth. Add vanilla and salt, then slowly mix in milk until you reach a creamy, spreadable consistency. Beat on high until light and airy.
If frosting feels too thick, add a splash more milk.
If too soft, add more powdered sugar.
Pro Tips for the Best Cake
Use room temperature ingredients.
Cold ingredients can cause uneven mixing.
Use high-quality sprinkles.
Jimmies hold their shape and won’t bleed into the batter.
Don’t overmix.
Overmixing leads to dense cake and broken sprinkles.
Cool completely before frosting.
Warm cake will melt buttercream instantly.
