Rainbow Cake-in-a-Jar

1 box white cake mix made according to package instructions

Neon food coloring in pink, yellow, green, turquoise, and purple

3 one-pint canning jars

Fluffy White Frosting (see recipe below)

Rainbow sprinkles

Preheat oven to 350 degrees. Thoroughly wash and dry the inside of each canning jar. Spray the inside of each jar thoroughly with nonstick cooking spray. Set aside.

Scoop about 1/2 cup of cake batter into five small bowls. It doesn’t have to be perfect, don’t panic if you get a little more or less of one color than another.  Tint each bowl of cake batter with the food coloring until very vibrant.

Spoon about 3 tablespoons of the purple batter into the bottom of each jar.  Spoon equal amounts of turquoise batter, then green, yellow, and pink.  Place the jars in a shallow baking dish, add about 1/4″ in water to bottom of the pan. Place baking dish in the oven and bake for 35-40 minutes or until toothpick placed in center comes out clean.

Remove jars and allow to cool completely before scooping a small portion from the top of your cake, cleaning the edge of the jar, and adding a hefty dollop of Fluffy White Frosting to the top. Sprinkle & serve!

These cakes can also be covered with the jar lid and saved in the refrigerator for up to 3 days!
