EASY RAINBOW CAKE

Ryder asked for a Rainbow Cake for his last two birthdays. Honestly, I didn’t want to take the time to make it.

Initially, I said no but reconsidered and surprised him. Making it as easy as I could, I started with cake mix. This is how I did it.

After mixing the batter, you will need to divide it into bowls to add the food color. (You can make as many different layers as you want. I have made this cake from four colors to seven colors.)

Easy Rainbow

I used a cake mix for the cake. And, instead of regular food coloring, I used food coloring by Wilton that’s designed to go in cake icing. These icing colors gave the layers intense colors that didn’t fade with baking.

Use a white cake mix and only use the whites of the eggs or the yolk will alter the color.

ADDING THE COLOR

To add this gel icing coloring, I use the end of a clean knife and dip it in only once.
You’ll need to separate the cake batter into 4 (or however many different colors you’re using) small bowls of equal portions.
Run that knife through the batter, then mix together with a spoon.
Wash knife or use a new one each time in order to not contaminate the colors.

I used four 8 inch cake pans for the layers: yellow, orange, red, and purple.

Previously, I baked cakes and sold them to the public, so I have plenty of cake pans. If you don’t have four pans, bake them in different batches. These layers only took 12 to 15 minutes to bake.

It doesn’t take much of the coloring, less than 1/8 tsp, ย for the results I got.

Red (it’s more hot pink) – it doesn’t show well in photos.

After the layers cooled, I frosted them with Cream Cheese frosting.

  1. Wow you’re right that does look easy! Super cool cake.. Pinned ๐Ÿ™‚

    1. You know, I’m really glad I did the cake for him and it really wasn’t as much ‘trouble’ as I thought.

    1. I got really quick at making them when I made them for a restaurant, but am really out of practice now. They make a pretty presentation, but I usually like to do a sheet cake.

      Are you coming to MS this summer?

  2. Oh Paula, this looks like so much fun! I’m such a fan of bright colors. I would even want my own birthday cake to look like that!! So. FUN! Thanks for the idea and posting on Sweet and Savory Saturdays.

  3. Oh wow, Paula, that looks AWESOME! I have never made a rainbow cake either because I’m way too lazy for that. You make it look so easy that maybe I’ll give it a try. Beautiful job!
