Funfetti Cake – homemade funfetti layer cake recipe made from scratch with sprinkles, fluffy frosting, more sprinkles and a drippy chocolate ganache. By our contributor, Olivia Bogacki.
Today’s cake delivers a bold pop of color, mostly because it has been a dreary winter here in Vancouver and I’m literally watching a torrential rain storm outside my window as I type this. I am in dire need of something bright and cheery, and this cake is the perfect ray of sunshine!
Don’t let the candy coated exterior fool you – this Funfetti Cake is the perfect balance of sweet and tart. A buttermilk cake paired perfectly with a cream cheese frosting. The sprinkles in the cake add a fun burst of color, and the drippy chocolate ganache gives it a little bit of elegance.
Funfetti cake is typically made using a white cake recipe, mixing rainbow jimmie sprinkles into the cake batter before baking. The sprinkles melt when the batter is baked, leaving behind a small fleck of color in the finished cake that sort of resembles confetti. While you could certainly just add rainbow sprinkles to a box cake mix and get a similar result, this homemade version is definitely a worthy upgrade. I kept the egg yolks in this recipe, essentially creating a yellow cake that’s rich, moist and buttery with a touch of sweetness both from the vanilla and the sprinkles. With sprinkles on the inside and sprinkles on the outside, it’s the ultimate birthday cake!
If you’re more of a purist, insisting that it must be white cake to be a classic funfetti cake, give this funfetti cupcake recipe a try. Just bake it as a two layer 8″ round cake instead of cupcakes.
This cake is really simple to decorate, but I do have a few tips for you to ensure it all goes smoothly.
To add the sprinkles to the sides of the cake, I first placed the cake on an upside-down bowl so that the sides of the cake would be floating and I could easily spread the sprinkles to the very bottom of the sides. I rotated the cake as I pressed the sprinkles in, starting from the top and working my way down. You could also try this sprinkle cake technique, but since the frosting was a bit on the softer side due to the cream cheese, I opted to press the sprinkles into the sides manually. Either way you choose, be sure to smooth the sprinkles out to ensure the ganache drips down nicely.
For the drippy ganache, I used a teaspoon to drip the ganache along the sides and then filled in the top. You can follow this tutorial here to see how I did it. Simple, straightforward, and works like a charm!
If you’re looking for a colorful cake for any celebration, or want to surprise someone special with a fun birthday cake, this is the funfetti cake for you!

For the Assembly:
Make the Funfetti Cake:
- Preheat oven to 350F. Grease and flour three 6″ cake rounds and line with parchment.
- In a medium bowl, whisk flour, baking powder, and salt until well combined.
- Using a stand mixer fitted with the paddle attachment, beat butter until smooth.
- Add sugar and beat on med-high until pale and fluffy (2-3 minutes).
- Reduce speed and add eggs one at a time, fully incorporating after each addition. Add vanilla extract.
- Alternate adding flour mixture and buttermilk, beginning and ending with flour (3 additions of flour and 2 of milk). Fully incorporating after each addition. Do not overmix. Fold in sprinkles.
- Spread batter evenly into prepared pans. Smooth the top with a spatula.
- Bake for approximately 30 minutes or until a toothpick inserted into the center comes out mostly clean.
- Place cakes on wire rack to cool for 10 minutes then turn out onto wire rack to cool completely.
Make the Cream Cheese Frosting:
- Beat butter and cream cheese on med-high until pale and smooth (approx. 2mins).
- Reduce speed to low and add sugar 1 cup at a time. Add vanilla and pinch of salt. Increase speed to high and beat for 2-3 minutes until pale and smooth.
Make the Chocolate Ganache:
- Place chopped chocolate and cream into a microwave safe bowl. Stir to combine. Microwave for 20 seconds, stir. Microwave in 10 second intervals, stirring in between, until ganache is smooth and silky.
- Set aside to cool completely before using on cake.
Assemble the Cake:
- Place one layer of cake onto a cake stand or serving plate. Top with approximately 2/3 cup of buttercream. Repeat with remaining layers and crumb coat the cake.
- Place cake in freezer and frosting in the fridge for 30 minutes.
- Frost the cake and smooth the sides and top. Place back in the fridge for 1-2 hours for frosting to set.
- Place a bowl upside down on a baking sheet to catch excess sprinkles. Place cake on inverted bowl. Gently, but firmly, press sprinkles into the sides and top of the cake. Letting excess fall onto the baking sheet.
- Chill in fridge for 30 minutes.
- Using a teaspoon, apply ganache near edges like so to create the drips. Pour some ganache on the top of the cake and spread with an offset spatula. (detailed tutorial here)
- This cake was baked in three 6-inch round pans, which are smaller than a traditional cake pan. Be sure to check the size of your pan! Alternatively, you could bake it in two 8-inch round pans.
- Frosting may be very soft. If so, place in fridge for 30 minutes to firm up.
- I ran my hands over the entire cake after adding the sprinkles to ensure a smooth surface for the drippy ganache. If using a firmer frosting, you can try using this technique to cover the sides with sprinkles.
