Rainbow Cake in a Mason Jar #recipe

Cakes in Mason Jars are all over Pinterest and I fell into the trap and got hooked on wanting to try this. After two attempts I mastered it!!  Aren't they beautiful!?  Oh and they are tasty too.  Nom!  

Ready to make your own Rainbow Cake in Mason Jars? These tasty treats are the perfect dessert for your upcoming St. Patrick's Day dinner but also this idea is something I would consider for a birthday celebration as well.

Rainbow Cake in Mason Jars

Boxed Cake mix of your choice, I used a white funfetti cake {prepared as directed}
Food Coloring: Red, Orange, Yellow, Green, Blue, and Purple
Mason Jars - pint size or smaller (at the bottom of this post you will understand why smaller is better!)


1.  Prepare cake mix as directed on box.  Preheat oven to 350.

2.  Clean/wash the mason jars and let them dry. 

3.  Separate the cake batter into six small bowls.

4.  Create your rainbow of cake batter!  Mix the food coloring well.  So pretty!!

5.  Fill your jars slowly.  I used about 3 tablespoons of each color.  Make your rainbow.  I did the traditional rainbow for two of my jars.  

6.  Fill to about 3/4 full if you want your cake to come to the top of your jar.  If you want your cake to be contained in the jar fill it to about 1/2 full.

7.  Put your jars in a baking pan that has about one inch of water in it.  The jars are ready to bake.  

8.  Bake at 350 for 35-45 minutes.  Really depends on your oven and how much batter was used.  

9.  Check the cake with a long skewer to make sure your cake is baked through.  

10.  Let cool for a couple hours and then frost your cakes and add sprinkles!  Serve and have fun!!

Cake in Jar Tips:

With the left over batter I made a smaller cake.  This allowed me to frost the cake and put the lid on top. I like this idea for gifts.  What a perfect way to transport cake to a friend or teacher on their birthday!  Yum!

Do not overfill your jars!  

Do not use a jar larger than a pint size!

I told you it took me two attempts to land this project and the picture above looks like a science project but I wanted to be honest with you!  

When I over filled my jars and used too large of jars the cake went every where.  Pretty but not good!  HA!  It was an experience and I am excited to try other designs for birthdays and gifts!  

Update!  On January 14, 2015, this amazing pinterest fail was featured on Good Morning America!  What an honor!!  I would have never thought my honest disclosure would get me on national TV!!  Check out the video here!
