Sharing is caring!

Nothing like celebrating with some fireworks on the Fourth of July! How about making a firework cake for the festivities! This Firework Sheet Cake is an easy way to bring a great dish to your patriotic bbq.

We’re making this super easy and using a boxed cake mix! If you want to stick to the red, white, and blue theme, I recommend going with a red velvet cake.

But of course, you can always mix up this cake and do whatever colors you’d like. It’s just time for Red, White & Blue here. Plus, the frosting on top makes it look like a fun firework display!

Pair this with these delicious 4th of July Frozen Yogurt Popsicles for an extra special treat.
