Why you’ll love this cake
If you loved funfetti cake growing up you’ll love this homemade birthday cake version! You’ll love it even more if you’re unable to eat Pillsbury Funfetti Cake due to a dairy allergy, as you can easily use dairy free options for this cake.
Thankfully we can still enjoy our favorite Pillsbury frosting and Pillsbury cookies!

Confetti Cake ingredients
- Whole Milk – For a dairy free option, we use Silk Nextmilk, whole fat.
- Vinegar – Vinegar helps curdle the milk.
- All Purpose Flour – If you’re gluten-free, our go-to is Bob’s Red Mill for gluten-free flour.
- Granulated Sugar – We haven’t tested this with sugar alternatives.
- Baking Powder – Not baking soda!
- Salt – To balance the sweetness.
- Oil – You could also use safflower oil, vegetable oil, or melted butter.
- Vanilla Extract – Use a good quality vanilla.
- Egg – If you can’t have eggs, you can use 1/4 cup applesauce, unsweetened.
- Sprinkles – We use Cake Mate brand.
- Butter – We use Country Crock plant butter to make dairy-free buttercream.
- Powdered Sugar
How to make Confetti Cake
Preheat the oven to 350 degrees F and grease 2 – 8×8 round nonstick cake pans with butter.
Combine the milk and vinegar in a bowl to make a DIY buttermilk.
In a stand mixer bowl, mix the flour, sugar, baking powder, and salt.
Pour the oil, vanilla, and eggs into the buttermilk mixture.
Next, mix the wet with the dry ingredients. Once combined fold in the sprinkles.
Evenly divide the cake batter into the two prepared cake pans. Bake for 30-35 minutes or until a toothpick inserted comes out with minimal crumbs.
Once removed, allow the cake to cool before removing from the pans.
Once cooled, place the cake onto a cake plate. We like to place some parchment paper underneath or use a cake board.
Even the cake out using a long knife or a cake leveler.
Next, use an offset spatula to add the frosting. You can use our homemade buttercream or store-bought frosting.
After frosting the top, add the second layer and spread the buttercream on the cake.
Decorate as desired.
