Rainbow Cake in a JarBrooke McLay
I’ve always had a penchant for sunshine in a jar. Doesn’t the very phrase itself, “sunshine in a jar,” roll off your tongue and fill your mouth with magic? While I’ve never yet found myself a sunshine in a jar, I think we may have just concocted it in our kitchen tonight. In this simple recipe, a basic white cake is turned into a slew of bright colors, baked to perfection, then topped with a creamy white frosting.
Cakes baked in jars can be topped with traditional metal canning lids and stored in the fridge for up to five days. They make a great treat to ship to someone, so long as you can ensure delivery to it’s final destination within 3 days. Of course, you don’t have to do anything special with your cake-in-a-jar. There’s something lively & different about serving personal-sized batched of cake in glass mason jars. They make for great dinner party conversations and ever better after-school suprises for your kiddos. Especially this one. Because, who doesn’t love sunshine in a jar?
Rainbow Cake in 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
- 1 can vanilla frosting
- Rainbow sprinkles
1. 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.
2. Scoop about 1/2 cups of cake batter into five small bowls. It doesn’t have to be perfect, don’t panic if you get a little more of less of one color than another. Tint each bowl of cake batter with the food coloring until very vibrant.
3. 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 40-45 minutes.
4. 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 buttercream to the top. Sprinkle & serve, or cover with a lid and store in the fridge or pop into the mail & surprise someone you love!
