Another continuation of rainbow inspired eats and treats geared towards PRIDE month! This fun and vibrant rainbow cake is made with literally just a handful of ingredients and fairly little hands on time. This cake uses one of the oldest tricks in the book as far as cake mixes go, and that’s simply using sparkling soda with the mix and nothing more!

That’s right. You can make a cake with a box of mix and a can of soda. Pretty impressive, huh? It’s so super easy to do too! Outside of that, you divide the batter and color it accordingly. I went with the rainbow colors of the PRIDE flag, but you can use whatever colors you wish.

I used standard gel food colors here and they turned out beautiful and vibrant with the white cake mix. Which I definitely recommend using a white cake mix and not any other for this very reason. Anything vanilla or otherwise will have a slight yellow hue to it.

The frosting here is one that really is best right away. You can store this cake in the fridge, but it’s really ideal to eat it pretty straight away. Or at very least be sure it’s covered in the fridge as the frosting does thicken as it sits out.
