Easy Rainbow Birthday Cake Using Skittles and Mini Marshmallows

When it comes to making birthday cakes for kids, the standard keeps getting higher and higher. The cost of birthday cakes is insane and the elaborate lengths people go to takes so much time and effort. I have no problem with people making these amazing birthday cakes - I'm just not skilled enough to do it myself!

After going to many kids birthday parties I can tell you that most cakes don't even get eaten. This is why I love this easy rainbow birthday cake. Yes, it uses a store bought cake (save yourself some time!) but you can always make your own using your favorite cake recipe.

Grab a packet of skittles and some marshmallows and impress everyone with this super easy rainbow cake!
