Ingredients

- Vanilla pudding mix: Use regular pudding mix, not instant.
- Vanilla extract: Use pure vanilla extract rather than imitation.
- Eggs: Adds flavor and color and provides the structure for the funfetti cake.
- Butter: Use unsalted butter so the frosting doesn’t end up salty.
- Powdered sugar: The best sugar for making frosting. It easily dissolves into the butter and whipping cream making a silky smooth frosting.
- Whipping cream: Moistens the frosting and adds rich flavors.

How To Make A Box Cake Mix Better
- Beat the cake mix, mayo, pudding mix, vanilla extract, water, and eggs until combined.
- Pour the batter into the prepared cake pans. Bake the cakes in your preheated oven until a toothpick inserted into the center of the cake comes out clean.
- Cool the cakes on a wire rack for 10 minutes and then remove the cakes from the pans.
- Top the completely cooled cake with frosting. Enjoy!
Tips & Variations
- Allow the cake to fully cool before frosting. Otherwise, the frosting may melt off the cake.
- Add some food coloring to tint the frosting to customize your cake for a special occasion.
- Use the toothpick method to check for doneness. Insert it into the center of the cake and when it comes out mostly clean or with just a few crumbs it’s ready.
- Allow the cakes to cool first in the pan so they don’t break when you try to remove them. The cakes will be softer when fresh from the oven which makes them more fragile.
Recipe FAQ
Yes, you can! Use a 9 x 13 pan for the same cooking times. Cool the cake completely in the pan on a wire rack and then ice and decorate the top.
Yes, of course! Follow the instructions on your baking mix for the cooking time if you’re making cupcakes. I suggest using cupcake liners in your pan to prevent sticking.
Storing
- Store. A fully made unsliced cake in the fridge up to 24 hours in advance. If you plan to store it longer or storing after it’s cut I suggest placing it in a container for storage so it doesn’t dry out. You can also store sliced pieces in an airtight container. The cake will last up to five days stored in the fridge but it may dry out slightly the longer it sits.
- Freeze. Store the unfrosted baked cakes in the freezer for up to one month if well wrapped. Thaw them out and then add the frosting. If already frosted, you can store the cake in individual slices or intact for up to one month. It may last longer depending on how it’s wrapped but it may start to take on some flavors from the freezer. Use a freezer-safe container or double wrap in plastic wrap followed by aluminum foil.
