This Rainbow Layer Cake is packed with a different flavor in every layer!

My husband made this Rainbow Layer Cake for Easter. I would suggest you may want to enjoy this cake at least once. It’s perfect for any celebration when you want to Wow the crowd. It’s huge so be sure to invite friends and family to enjoy it with you.

This Rainbow Layer Cake is rather majestic with four layers! Slice those layers thin and you should be able to get about 20 slices so it will feed a crowd. One slice covers a full size dinner plate.

It’s what I lovingly refer to as a ‘cheating cake,’ because it’s a box mix but trust me when I say, the flavors are amazing! There are many, many box mix recipes out there which will make you think you are eating a cake made from scratch. This is one of those. Don’t you just love Tricks with Cake Mix recipes! We do.

It’s pretty tall, don’t you think. We made this disappearing flavor packed cake for Easter and everyone loved it.

We didn’t use the cool whip frosting in the magazine recipe. Instead, Stacy made the basic buttercream frosting which is a family favorite. We also stacked the layers in a different color pattern than Kraft just for the fun of it! We were very happy with this recipe and will likely make it again for a special occasion.

INSPIRATION

This cake was inspired by the Rainbow Layer Cake found in a magazine put out by Kraft a few years ago. They used a whipped cream frosting which doesn’t appeal to anyone in our family so we went with a Buttercream frosting. You can find our Buttercream frosting recipe as you scroll down.

THE SECRET

The secret to the flavors is using dry gelatin mix. We used; Raspberry, Orange, Lime and Berry Blue gelatin. It’s a pretty cool trick which we have used again. You could easily make a cake in team colors using the gelatin trick.
