Rainbow Cake in a Jar

Cake in a jar

I love how mason jars are so popular right now!  I teamed up with a cute bunch of girls and we each shared a creative a idea with things to do with mason jars. I chose to make rainbow cake in a jar!  They turned out so cute and were a huge hit with the neighbor kids! I hope you enjoy them!

Rainbow Cake in Jar (plus 10 other mason jar ideas!)


1 box white cake mix (made according to package instructions)
Food coloring
4 one pint canning jars
1 can vanilla frosting
Colored sprinkles


Preheat your oven to 350 degrees.  Make sure you  wash and dry the inside of each canning jar. Spray the inside of each jar  with nonstick cooking spray then set aside.

Scoop  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 bright. (I used a lot of food coloring!) The colors I did were red, blue, purple, yellow and green. But you can use any colors you want!

Spoon about 3 tablespoons of the red batter into the bottom of each jar. Spoon equal amounts of purple batter, then blue, green, and yellow. Place the 4 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 30-35 minutes. Make sure you watch them! You don’t want them to turn too brown because you want to be able to see the colors from the outside.

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!

    Hello, thank you for sharing your tutorial. I love the idea. I found a box full of mason jars last weekend at a yard sale and I was looking for some ideas to use them for crafts. And I stumbled upon your blog. I have included a link to your page from mine. I do hope that is ok. If not please let me know I will have it removed.
