Rainbow Cake in a Jar
Remember you can change the colors to match any holiday, Halloween, Valentine's Day, Christmas and more. You can even make then for wedding guests with the wedding colors and more!
- 1 box cake mix (white) Made as the box says.
- Neon food coloring in the colors pink, orange, yellow, green, blue, & purple
- 3 one-pint canning jars
- 1 can white frosting (vanilla)
- Sprinkles (I used rainbow)
Preheat oven to 350 degrees. Clean each jar then spray with cooking spray. Set to the side.
Divide the cake batter evenly into 5 small bowls.
Tint each bowl of cake batter with the food coloring until you have a very strong color.
Spoon 3 tablespoons of the purple cake batter into the bottom of the jars. Spoon the same amount of blue, then green, yellow, orange and pink.
Place the jars in a shallow baking dish, and add about 1/4 inch of water in the baking dish. Place dish in the oven for about 30 minutes until cooked through.
Remove jars from the baking dish to allow to cool completely. Then scoop a small portion from the top of your cake and add a dollop of vanilla frosting to the top. You can tint the frosting or use any flavor I think the white looks best!
Sprinkle & serve, or cover with a lid and store in the fridge.
