This Homemade Funfetti Cake is a delicious cake for all ages! Using my homemade confetti cake mix, it tastes infinitely better than any prepackaged cake mix and is just as easy to prepare. Yields a 9×13 or a 2-layer (9-inch) cake or 24 cupcakes.

Ironically it’s almost been 7 years (to the day) that I last shared my funfetti cupcake recipe. Haileigh turned 10 and I remember struggling with her becoming double digits. That year, she had a special request for funfetti cupcakes. I remember it like it was yesterday. Wasn’t it?

Today she turns 17 and I’m not struggling as much this year as I did when she turned 10. But catch me in about 12 months when she graduates from high school and heads to college. I’ll probably be sitting on the couch with this homemade funfetti cake or a tub of ice cream (maybe both) in my lap and a fork or spoon in my hand eating my feelings. That’s just how I do.

Homemade Funfetti Cake

Every year it’s been my personal mission to give you an alternative to buying prepackaged, store-bought cake mixes. So far my little collection consists of yellow, white, chocolate and now funfetti cake mix! I decided to take my funfetti cupcake recipe and break it down to a mix (to be made in advance if needed) and then make the cake so I can get accurate baking times.

I’m pretty excited about this most recent one because it’s just as easy and tastes BETTER than any store-bought funfetti cake mix I’ve ever made in the past.

Homemade Funfetti Cake ingredients

To Make this Homemade Funfetti Cake You Will Need:

  • homemade funfetti cake mix
  • whites
  • whole milk
  • vanilla extract
  • colorful sprinkles – I prefer to use the long slender sprinkles as to the round ones

cake mix in bowl of stand mixer

Preheat your oven to 350℉ (or 180℃).

Throw 1 recipe for homemade cake mix into the bowl of your stand mixer that’s fitted with the paddle attachment.

combined wet ingredients

Then in a large, liquid measuring cup add 4 egg whites and 2 teaspoons pure vanilla extract to 1-1/4 cups of whole milk. Use a whisk to combine well.

add wet into mixer bowl

cake batter in bowl

With the mixer on low-speed, slowly pour in the wet ingredients. Mix until just combined.

add sprinkles

Lastly, pour in the 1/2 cup of sprinkles before stirring by hand to combine thoroughly.

pour batter into prepared pan

Pour the cake batter into a buttered, lightly floured and parchment paper lined 9x13x2 baking pan.

spread batter evenly

Tap the pan on the counter a few times, doing this will allow any trapped bubble to escape.

Then slide the cake pan or pans onto the middle racks of your preheated oven and bake for 30 to 35 minutes or until a cake tester comes out clean or with just a few crumbs attached.

cake inverted onto wire rack

Allow the cake to cool in the pan for 15 minutes before running a knife around the edge and inverting the cake onto a wire cooling rack. Remove the parchment paper and leave the cake upside down while it cools. By doing this, you can easily invert the back, this is if you plan to serve it from the pan. Doing it this way allows the cake to cool faster. It will also give you peace of mind when you’re serving the cake, knowing that it won’t be sticking to the pan.

Once cooled I add back into a clean 9x13 pan

Once the cake has cooled I transferred it back to a cleaned 9×13 pan. If making a 2-layer cake you can skip this step.

If you’re looking for the perfect frosting to go with homemade funfetti cake, my go-to vanilla buttercream frosting is superb!

Spread the frosting evenly over the cooled cake. Any extra frosting can be saved, refrigerated and enjoyed with graham crackers later. 😉

And of course, top with more sprinkles.
