Rainbow Cupcakes in a Jar





Introduction: Rainbow Cupcakes in a Jar

About: I love to recycle and upcycle.

Step 1: What You'll Need

Preheat oven to 350f

What you'll need:

1 boxed white cake mix
1 can of white frosting
variety of Wilton icing colours
12 125ml (4oz) canning jars

Step 2: Step 1:

Make the white cake as per the instructions on the box. Then divide the cake mix up into portions (you don’t have to be exact). Add colouring to the cake mix. I used: No Taste Red, Lemon Yellow, Teal, Royal Blue and Violet (most of the colours of the rainbow).

Step 3: Step 2:

Add about 1 tsp of each colour into the canning jars. Place the canning jars on a cooking sheet with about 1/4″ of water on it. Bake in the oven at 350f for 25-30 minutes.

Step 4: Step 3

Remove from oven and let them cool completely.

Once cooled remove the tops of the cupcakes to make room for frosting. Ice the cakes with the frosting and top with sprinkles.

Step 5: Enjoy!

    OMG im totally going to make this!

    All I can think is Fairy Cakes! I'm saving this!

    Ah, what a good way to present the colorful cakes

    First off, thank you for the beautiful idea!

    About how many of the 4oz jars would you say a box of batter would make? I plan on making these for a friend's going-away party in the colors of his new college, but I don't want to end up with too much left-over batter.

    wait... can you use like baby food jars?

    where can you get canning jars?(:

    FANTASTIC! i love these. way to make a simple treat extraordinary!

    I made them too! I added a TON of dye and they came out super bright and pretty!

    The only problem was, I couldn't find glass jars, so I had to make them the traditional way. This was nice, though, because it dyed the white wrapper the colors of the cupcake! Brought them to school and everyone adored them!

    These look great. In the past, i have put too much dye in stuff and you can actually taste a bitterness. I will have to retry. How did you fill the center with icing like that?

    These look fabulous cvale! Great colour :) Thanks for taking the time to comment and post photos.


    to enjoy can you get the cupcakes out or do you have to eats them with a spoon?
