Whatchamacallit Popcorn

So it’s the second installment in Candy Bar Week!

Did you guys like round one?  In case you missed it I made these, and Bridget made theeeeeeeese!

Right? I knew when we decided to do candy bars, that I wanted to do something with Whatchamacallits.  Do you guys remember those?

They aren’t super easy to find these days, and I’m not sure why.  They are ridiculously good…it’s a peanut butter krispie bar, topped with caramel and coated in chocolate.

First I thought about making a homemade version, which I think would be pretty simple…I think I’ll do that soon…but then I thought that the textures would really work well in a popcorn snack mix.

I wish I could say that being right so often is exhausting…alas, it’s not.

The great thing about this, is if you can find the candy bars, chopping them up and adding them is a fun addition, but if you can’t find them, the popcorn mix itself has all the flavors and textures right in there, so it really IS Whatchamacallit Popcorn..Not just caramel corn with candy bars in it.

Here are the details:  Peanut Butter Caramel Popcorn with Krispy cereal mixed in for extra crunch drizzled with chocolate.

Just pop your corn…

Then make your quick caramel sauce…at the end add peanut butter.

It will be amazing looking…

Just pour it over your popcorn.

If you’re lucky enough to be able to find the Whatchamacallit bars, chop them up…I used about 5.  You don’t have to be exact.

And yeah…it’s basically the perfect snack.  Crunchy, not at all chewy…peanut buttery, caramelly and salty/sweet.

You should make it.

I’m getting on the bandwagon much later than all the other posts, but for all my fellow Canadian friends, the Special Crisp bar (by Hershey’s) is the Canadian equivalent to the Whatchamacallit, apparently! I’m going to give it a try today! Yumminess!!

In summary, you have pretty much created my perfect food here. Holy moly!
