This homemade funfetti cake recipe is so simple to make, only requires pantry staples and rainbow sprinkles! Its a buttery vanilla cake, with flakes of color throughout and topped with a from scratch vanilla buttercream frosting.
Preheat the oven to 325°F. Spray three 7” round cake pans with non-stick baking spray and line the bottoms with parchment paper.
In a large mixing bowl, beat butter and sugar until light and creamy. Add one egg at a time, beating well after each addition.
Add vanilla extract, almond extract, and vegetable oil and beat well.
In a separate bowl, mix together the flour, baking powder, and salt.
Add half of the flour mixture to the butter mixture and begin to beat. Add half of the milk, then the remaining flour mixture, then the rest of the milk. Beat just until fully combined.
Fold in ½ cup of rainbow Jimmies.
Divide the batter between the three prepared cake pans.
Bake for 35-40 minutes, until a toothpick inserted into the center comes out with just a few crumbs.
Cool cakes on a cooling rack for 10-15 minutes, then turn out from the pans and cool the rest of the way.
To make the frosting in a standing mixer, beat the butter on high speed until lightened and fluffy. Add powdered sugar gradually.
Beat in the extracts. With the mixer running, pour in the heavy cream until the frosting is light and fluffy and desired spreading consistency.
If you’d like to fill the cake layers with funfetti frosting, set aside about 1 cup of frosting. Mix in 2 tablespoons of sprinkles.
Place the first cake layer on a cake stand or platter. Add about ½ cup of frosting to the top and spread to the edges. Stack the second layer on top and add a layer of frosting on top of this one also. Top with the third cake layer.
Frost the cake with the remaining frosting and decorate as desired. We piped a few swirls on the top of the cake and added sprinkles to the tops and around the bottom perimeter.

Notes
Storage:Keep the leftover cake that has been cut in a container or covered with plastic wrap for up to 5 days in the fridge. Uncut cake can be stored without covering. Notes:Cake layers can be frozen for 1-2 hours (or up to 3 days) for easier frosting and assembly. It also makes them moister. You will have more than enough frosting for the entire cake and a thick filling. If desired, halve the frosting recipe for a simpler cake. The extracts give the cake the classic funfetti flavor that you think of with the box mixes. The vanilla and butter in the frosting will yield a cream color. For a whiter look, use clear vanilla extract. White shortening can be substituted for some or all of the butter, but the flavor will be compromised. Adjust the cook time if you want to make a 2 layer cake using 8 or 9 inch pans.
