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).

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.

Remove from oven and let them cool completely.

Ah, what a good way to present the colorful cakes
shilicious3 years ago
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.

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.

Did you do anything fun with the sliced-off bits of cake top?
mommyknows1 (author)  canida3 years ago
My five year old ate them before all of the other kids came home from school. She absolutely had fun :)

Why use the colored frosting in the batter instead of food coloring? What does that do for you?
mommyknows1 (author)  gijoebob3 years ago
The icing colours are food-colouring ... I think Wilton markets them for colouring frosting but they can be used to dye other food products.

HTH
Ah, that makes more sense. Thanks!

As the grandsons would say "You ROCK!"

Thanks.

Did you grease the jars first?
mommyknows1 (author)  Audreyvgs3 years ago
I didn't grease the jars. I thought about it, but seeing as they don't need to come out of the mold easily (using a spoon to scoop and eat), and you want the rainbow effect to be visible with no barrier, I decided not to.

They didn't stick much at all.
I never knew you could get so many colors. Pretty to look at.
mommyknows1 (author)  NaturalCrafter3 years ago
Thank you NaturalCrafter :) I only used five colours but they combine to make even more.
With all this talk of food I made cookies today...lol So many projects, so little time..but its all fun sharing it too.

I've been doing rainbow cupcakes with food coloring for a while now, but putting them in glass jars is both clever and gorgeous! Thanks for the post.
mommyknows1 (author)  poepadoe3 years ago
Thank you :)
Looks excellent. is the idea to use a fork or spoon to eat the cup cake?
mommyknows1 (author)  porcupinemamma3 years ago
Thank you. Yes, you'lll need to use a spoon or fork.
All rightie then. Thanks so much!! :0)
