Recipe Summary
Nothing says "it's time to party" quite like confetti cake. This rainbow-speckled cake was a staple of our childhood birthday celebrations, and this grown-up, layered version is made to celebrate any occasion, big or small.
Our Confetti Cake with Vanilla-Sour Cream Frosting puts a grown-up twist on the whimsical classic. This confetti layer cake boasts three layers of festive sponge cake—learn our top tip for upgrading your boxed cake mix here—sealed in with a sophisticated Vanilla-Sour Cream Frosting. Dress up your favorite confetti cake mix with an icing that's pleasantly tangy, thanks to the addition of sour cream. Salted butter also makes a difference here and balances out the sweetness of the cake.
Of course, it's practically a requirement to decorate this fun cake with rainbow sprinkles. Recruit the kids to help and let their imaginations run wild. You can even add sprinkles right into the frosting for a stained-glass effect.
