1 box white cake mixed according to package instructions
Neon food coloring in pink, yellow, green, turquoise, and purple
3 one-pint canning jars (Wide mouth works well)
1 can vanilla frosting
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 cups of cake batter into five small bowls. It don’t have to be perfect. 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 in the baking dish. Place the baking dish in the oven and bake for 35-40 minutes. Inset toothpick, if comes out clean it is done, if not, bake another 5 minutes and recheck.
Remove jars and allow to cool completely before scooping a small portion from the top of your cake and adding a hefty dollop of vanilla frosting to the top. Sprinkle & serve, or cover with a lid and store in the fridge or pop into the mail & surprise someone you love!
