Storing Your Cake

Because of the fresh berries in the buttercream frosting, you will have to store your cake in the fridge. Make sure it is covered with a lid or foil to prevent the cake from drying out.

You can also freeze any cake you don’t plan to eat right away. Just place in a proper container and freeze for 2-3 months. Then thaw in the fridge overnight or on the counter for 30 minutes to an hour.

Change Up The Frosting

Now, you are not stuck with the raspberry frosting if you want something different. You can use store bought frosting or opt to make a different flavor of homemade frosting.

Vanilla, chocolate, or even a strawberry frosting would be delicious! Feel free to change it up to fit what you prefer.

Funfetti Sheet Cake FAQs

Here are some common questions asked when making this homemade cake recipe.

Can I make cupcakes instead of a cake with this recipe?

You can make cupcakes instead of a cake easily. Just whip up the cake mix the same way and spoon the mixture into the cupcake tin that is lined with liners. This will make around 24 cupcakes. Bake for 12-15 minutes or until the cupcakes are fully cooked.

Can I make this cake without a hand mixer?

You can make cake without a hand mixer. The biggest thing is making sure to take time to cream the softened butter and sugar together for a bit. You want it to become paler in color and really creamy. Make sure to take the time and use a whisk and work the butter and sugar together.

What type of sprinkles to use?

Jimmies are the classic sprinkle used when making a funfetti cake. You are welcome to change them out but know the texture could alter when baked depending on the type of sprinkle you use.
