DIY Rainbow Cake


{insert happy dance}

We are going to wrap up the week with something that is bound to rock your socks… This DIY rainbow cake.  I told you when I posted  Monster’s Color Splash Birthday Bash, that I’d show you how to make this beautiful piece of culinary goodness!  I saved my favorite colored party detail for last.  So here it is…

THE CAKE! This rainbow cake was a bit tricky and time-consuming but was worth every second spent. As soon as the first piece was sliced I heard Oohs, Aahs and even saw a few jaws drop. I recommend this show stopper for any event, rainbow themed or not.  ANY party would be lucky to have this cake grace its plates. And the good news… you could make this gorgeous layered cake ANY colors you want. YES I KNOW, AH-MAZING! You can thank me later!

  • white cake – 3 boxes
  • food coloring – amt. depends on desired colors
  • icing – 3 containers

You will also need:

  • eggs, oil & water – cake ingredients
  • mixing bowl

  • spoons
  • spatula
  • containers to separate batter
  • cake pans


Make cake batter according to directions.

Separate into containers evenly. (I measured 1 cup of batter at a time)

The FUN part:

Dye each container the color you’d like.

**warning… If you’re anything like me and get a little carried away in the kitchen, wear an apron and gloves. When I was finished, my shirt and hands looked as if they were assaulted by a Crayola box!!

Bake your cakes normally but cut the time.

Check frequently so you don’t overcook.

Mine were perfect after 17 minutes

Allow cakes to cool.

Admire your awesomeness.

Call anyone around into the kitchen to admire your awesomeness.

Insist they tell you how awesome you are!

Once cakes are cool, slice the tops off to make each layer flat and even.

Eat the cut offs.

Check out your now colored tongue!

ON YOUR CAKE PLATE, place your first colored layer.

Ice the sides AND top.

Place next layer on top and repeat steps for all colors.

After all layers are stacked and iced, because you are not Betty Crocker, your cake may need a little straightening.

Get your hands messy, start at the bottom, grip your cake with both hands and CAREFULLY work the layers into place.

DON’T worry about the icing, you can fix that once your cake stands up nice and straight.

When your cake looks less like the Tower of Pisa and more like a layered cake, pretty up the icing and decorate how you’d like.

Refrigerate if not serving promptly.

Cut slices carefully.

When EVERYONE asks about your masterpiece -aka- “The Most Amazing Cake They’ve Ever Seen” smile and pretend it’s just something you “whipped” up!

Bask in your glory.

Take tons of pictures.

KNOW that you ROCK and your cake will be talked about until the end of time!!
