A Kit Kat Chocolatory opened up in Toronto for 3 weeks this month...except I don't live in Toronto anymore. Of course, I excitedly checked in with my cousin back home to see if she was going to endure the queues. And she said, "You were the first person I thought of when they announced the shop! But then I thought, 'She'll probably make her own anyway'." She has a good point!

So I set off on a mission to make my very own copycat Kit Kat molds, pawsitively intent on a kitty kat theme. Coincidentally, there's a Casting Contest here on Instructables, so I figured to take pictures of my every step to enter into the contest.

My cousin did check out the Kit Kat Chocolatory during its limited run. She couldn't even make it inside. The line-up was that long. And apparently, the Chocolatory ran out of supplies so they ended up closing the shop an entire week earlier than scheduled. That's okay though, because I told her next time I visit Toronto, I'll be bringing her my very own!

And now, you can make your own, too. As many copies as you want!

Step 1: Kit Kat Making Supplies

I picked up a box of Amazing Mold Putty at my big box crafts store (that would be Michaels) for $12.50 after 50% off coupon. One box makes exactly 3 Kit Kat molds. For $4 and change, you can get a mold that you can customize, that can't be beat!

Is it as amazing as marketed? Yes. It's as easy as playing with Play Doh with a reasonable 3 minute working time, super fast 30 minute cure time, and miraculously results in a product that is a flexible rubber mold. Most importantly, it is one of few available on the craft store shelves that's intended for food use and FDA approved.

So you'll need that putty and the following:

-Kit Kat bar

-10 pt to 12 pt heavy stock for the custom designs (it has to be thick enough to create an embossed effect on the chocolate bar)

-Pencil, scissors, ruler, glue stick

-Sharp/precise craft knife (I use a #12 surgical blade)

-Cutting mat

-Foam board

-Hot glue gun

-Small rolling pin

Excellent ~ible i must say. I once made treasure chest cake with kitkat. I should have made these aborable custom designs for it.

Thank you! You can still make another cake that's totally custom!

I love everything about this! Love Kit Kats. Love Cats. Now I love Cat-themed Kitty Kit Kats.

Happy to hear you enjoyed this Instructable!

My father was chief engineer at Rowntrees and was the one person in the factory who had the formula for the volume of a Kit Kat. It was quite complicated when he showed it to me - it was written in pencil on the back of an envelope (or perhaps that's just in my imagination).

He explained that as the price of chocolate increased he would re-design the moulds to be smaller and smaller until the biscuit started showing through. Then he would increase the size and Rowntrees would put up the price.

Interesting! I guess Kit Kats started off with the wafers being fully covered. That was something I never even noticed until I started doing these molds and realized the wafers barely have a coating of chocolate. I don't remember them being that way when I was young.

We had Rowntree back in Canada in the 1980's. The name brings back so much nostalgia!

Thanks for your story!

These are perfect in every way! Love the colors and the cat details :D

Thank you!

Truly brilliant. I clicked to check if there was a recipe for the kitkat and there was! You got my vote, great instructable.

Thank you so much for your vote! I hope you try out your very own custom Kit Kat flavors and designs, too!

I love the number of different flavours you've put in _one_ 'ible! Also, the freeze-dried strawberry idea is amazing and solves a long-standing problem. Thank you so much for this :-)

Thank you!

The powdered freeze dried strawberries are as natural as flavoring gets and I really love it, but they do impart a speckled look and that might matter to some people. I've in the past gotten Lor-Ann flavoring oils specifically for candy/chocolate making so there's no seizing. I never got a strawberry flavor, but I bought their mango and pistachio and I felt they didn't taste natural enough...or maybe I was just heavy-handed!

These are simply awesome! Every little thing about these I love from the personalized Kit Kat molds with the cat face to the different flavor combinations! Thanks for sharing this so much. I feel bad for the Kit Kat that was sacrificed to make the mold, but it was for the greater good :D

LOL!! I'm actually still hanging onto my sacrificial Kit Kats in the fridge with a post-it: DO NOT EAT, HAS GLUE. I wanna make another batch of molds.

Thanks so much!! I'm glad you enjoyed the Instructable!
