1
Preheat your oven to 350 degrees/F.
-
2
Mix your cake mix, egg whites, and vegetable oil.
-
3
If you can't separate an egg, crack the egg into a slotted spoon and the whites will run out while you're left with the yolk.
-
4
(NOTE: The ingredients you need for the cake mix vary by brand.
-
5
I'm using Betty Crocker).
-
6
Separate your cake batter evenly among 6 plastic bowls/cups.
-
7
Dye each bowl with one color.
-
8
You can add Indigo into the rainbow if you have a dark blue dye, or you can add some black to blue.
-
9
Place a small amount of violet (purple) batter into the bottom of the liner.
-
10
Now add the same amount of blue.
-
11
This is where it gets tricky.
-
12
If you want even layers of colors, pour them while moving the spoon across the liner and smooth it out.
-
13
Add your green, then yellow, then orange, then red should be your top color.
-
14
Bake these for about 18-23 minutes (21 minutes worked well) or until a toothpick comes out clean.
-
15
Let these cool completely in the fridge or freezer before frosting/decorating!
-
16
TIP: If you plan on piping your frosting, keep the tub in the fridge until you need to use it.
-
17
Avoid using the whipped/light frosting.
-
18
Decorate with assorted sprinkles, candies, and colors!
-

It's up to you!
