How to: Rainbow Cupcakes in a Jar

Published by on

My rainbow cupcakes in a jar were inspired by this babble post, however, I just thought one pint jars were just way to BIG. My kids don’t need that much cake. So … using 4oz (125ml) jars … I present cupcakes in a jar!

Make sure you have a helper.

{preheat oven to 350f}

You’ll need:

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

My creation

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).

My creation

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.

Tip: Only fill the jars about 1/2 full. I think mine were too full and many ended up way to big!

Remove from oven and let them cool completely.

My creation

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

Cool idea! We bought that exact size mason jar yesterday for some jam we were making, but ended up using the next size up instead. Thanks for the idea.

Ashton · June 1, 2011 at 3:35 am

That will seems to be excessively neat. I’ll surely check it out for this specific end of the week.

Wow, what an ideal. Here I am building a website on cupcake packaging and that thought of using canning jars never entered my mind.

Amy · September 16, 2011 at 4:45 pm

I’ve always to know how to make this cute rainbow cupcakes. I always see this on Tumblr. And finally, I found it here. Thanks so much for sharing this. :)))

Vi · January 25, 2012 at 6:40 pm

hi! these cupcakes are awesome, I really want to try them out but I have a doubt. The jars that you use, are they made of special material for the oven? or you use regular ones?

pest control · February 18, 2012 at 12:14 pm

Good initiative.

Paizley · February 19, 2013 at 11:55 am

I checked my 4 oz jars but they were only 113ml :-/

    Kim Becker · February 19, 2013 at 9:07 pm

    Close enough :) Just maybe take a couple minutes off of the cooking time.
    Thank you for stopping by.

candi · April 21, 2013 at 9:49 pm

Can you use any ol jars or does it have to be canning jars? Im thinking reusing baby food jars (the larger ones) Hope someone can let me know if that’ll work!!
Thanks

jane · April 28, 2013 at 7:33 pm

i needed something rainbow to bake for some friends and this looks perfect

Darlene · August 8, 2013 at 5:26 am

Love this idea for my grand children thanks a lot

Lisa · September 8, 2013 at 8:59 pm

Way cool. I am going to do this as a way to send cupcakes to my nephew in college.

Bryanna · May 2, 2014 at 9:01 am

So you put 1/4″ of the water in the jars with the cake mix when you bake them? I just misunderstood that part…I want to make these for my daughter’s birthday at the end of the month, and I obviously dont want to screw them up! Lol

Mandy · July 8, 2014 at 11:56 pm

I am planning to make these for my grandmas 75th bday I fell in love with them when I saw them

terristeffes · January 19, 2016 at 9:45 pm
