No birthday is complete without a sprinkle filled FUNFETTI CAKE! This recipe is super moist and loaded with sprinkles and real vanilla extract. The entire cake is smothered in a simple vanilla buttercream and loaded up with even more sprinkles. It’s so hard to look at this cake and not smile!
What flavor is Funfetti Cake?
Funfetti cake is may more than your average vanilla cake! Not only is it loaded with sprinkles, but its texture is much richer than regular cake. It’s buttery, moist, and extra sweet.
Funfetti cake is also typically made with whole eggs rather than egg whites to give it that dense and rich texture. For my recipe, I also added oil to the batter to create a super duper moist cake. It also has a little extra vanilla extract for that bold vanilla flavor.
How to make Funfetti Cake from scratch
This cake is so rewarding to make from scratch. Not only is it impressive, but it’s way better than box mix funfetti cake. It has that homemade flare and flavor you just can’t get from a box.
To make sure yours turns out perfect, here’s a few tips to follow:
- Room temperature ingredients – It’s important to make sure your butter, eggs, buttermilk, and sour cream are all at room temperature before starting. Not only does it create an extra smooth batter, but it also allows the cake to bake evenly. Think of it this way, if you’re putting cold batter into a hot oven, it will take a few extra minutes to warm it all the way through which can lead to an uneven bake. Room temp is the way to go!
- Aerate – Since the batter uses whole eggs and oil, the cake can easily turn too dense and heavy. The first step in the recipe is crucial to get an airy cake by whipping the butter and sugar together. Whip for 3-4 minutes on high speed, or until it sticks to the sides of the bowl and reaches a fluffy consistency.
- Leaveners – Another key ingredient is the leaveners (baking powder and baking soda). Make sure yours aren’t expired before baking! Both should have an expiration date on the package. They last between 6-9 months unopened.
- Cake strips – This is optional, but if you reeeallly want a deliciously moist texture all throughout use cake strips. These strips are specifically designed to be wrapped around cake pans in order to keep the edges of the pan cool while the cakes bake. They’re damped before baking which prevents the outside of the cake from baking faster than the inside.
- Cake pans – This recipe is best for 3 – 9″ round cake pans. If you have 8″ cake pans, those will also work. Just make sure to leave out about 1 1/2 cups of batter. The amount of batter in this recipe is just a hair too much for 8″ pans and if they’re filled too high, the centers will sink when baked. This isn’t a HUGE issue as the centers will still be done, it will just be a bit more dense in the middle.
What can I use instead of buttermilk?
Buttermilk is used in this recipe due to its high acidity. Combined with baking soda, the two work together to break down gluten and create a light and tender texture.
If you don’t have buttermilk, you can make your own! Measure out one cup of milk, minus a tablespoon. Then add one tablespoon of white vinegar or lemon juice. Give it a stir and let the mixture sit for about 10 minutes to curdle.
Can I subtitute the sour cream?
Yes! A great sub for sour cream is 2% plain Greek yogurt. You could also sub the 1/2 cup of sour cream for an extra 1/2 cup of buttermilk if you’re really in a pinch.
What are the best sprinkles to use?
When it comes to adding sprinkles to cake batter, the type of sprinkles you use is very important. To mix into the batter, always use jimmies (these are the long and skinny sprinkles) because they won’t bleed into the batter. Don’t use nonpareils (the tiny balls) inside the cake because they bleed very easily and will muddy up the color of the cake.
As far as the outside of the cake, use whatever sprinkles you like! I chose a combo of both jimmies and nonpareils.
Can I bake this as a sheet cake?
Yes! Pour the batter into a well greased 9×13 baking pan. Bake at 350F for 40-45 minutes or until a toothpick in the center comes out clean.
How do you decorate a funfetti cake?
Now for the fun part! There are many ways you can decorate a funfetti cake. You can cover the entire cake in sprinkles, add buttercream swirls and a light dusting of sprinkles on top, or add sprinkle splatters like I did here.
To make the sprinkle splatters, add the sprinkles right when you’re done frosting to ensure they stick. If your buttercream is too thick or dry, the sprinkles will just bounce right off so make sure you have the texture just right!
First, mix together 2 parts jimmies and 1 part nonpareils. Then, place your cake over a large baking sheet to minimize the mess. I had tons of sprinkles fall into the baking sheet, and the rest were licked up by my dog sitting at my feet. Minimal clean up!
While the buttercream is still fresh, add a cluster of sprinkles to the top center of the cake. Then, randomly add smaller clusters of sprinkles all around the cake. To get the sprinkles on the side, grab a pinch of sprinkles and toss it against the sides of the cake in short and rapid motions. Go back round and gently press the sprinkles into the cake to make sure they stay there.
How to store your cake
If you are storing the whole cake pre-sliced, you can keep it in the fridge uncovered for a day. If you’re keeping it longer than that, I recommend using a cake container to ensure it doesn’t dry out. It will keep in the fridge untouched for 3 days for maximum freshness.
If it’s already sliced, you can either slice the entire cake and store the slices in a container, or place the entire cake in a cake container and press plastic wrap up against the sliced openings (this prevents it from drying out too quickly). Both stored in the fridge and will keep for up to 5 days.
