Just Add Water Cake in a Jar — 32 Comments

  1. Um….I have a few questions:
    1. Where do I buy frosting chips? I’ve never seen them.
    2. Frosting from a can?
    3. Where are the baking directions?


    • Hi, They aren’t frosting chips they are chocolate chips that you sprinkle on top of the hot cake. They melt and can be spread like frosting. Yes, if frosting is listed it is the store bought frosting. The baking directions are on the directions print out that goes on the lid. If you scroll down past the recipe you will come to several labels one of those is the directions label.

  2. Sheryl, I am a leader of a Girl Scout troop and we are making these for an assisted living home in the area. I have a question as to your ingredients and directions. Under “for all cakes” is the cake mix of any flavor the same as the “5 level tablespoons Funfetti cake mix” or are they different? As in, is one a base and then you add the tablespoons to the base then distribute? I apologize but when working with 9-12 yr old girls I find that its better to ask the odd questions before they throw them at me. Thank you!

    • Hi Victoria, What a great activity for the girls. Yes, you will need to add the extra ingredients to whatever flavor of cake mix you decide to use and then serve up the 5 tablespoons into the pouches.

  3. Thank you! I am making these to go in a care package going to my son and his friends at college. So much cheaper than the mug in a cake boxes they sell and many more flavors!

  4. I also wanted to say THANK YOU!! this is by far the nicest site I have ever seen you are so generous to post this! Happy Holidays!

  5. How long can these be stored? I am making them in bulk for others to give to customers at work and I’m needing to know how to store them.

  6. Hi – These are great! I was wondering if you have directions for baking in a conventional oven instead of a microwave? Thanks!

    • Hi Tracey, The first section of the recipe card titled “For all Cake mixes” is for a whole cake.
      1 (15.25 ounce) cake mix
      2 teaspoons baking powder
      ¼ cup plus 2 tablespoons dry milk
      1/8 teaspoon salt
