Layer one was super easy! I put down parchment paper (so I wouldn't slice up my pan when I cut the candy), but it ended up being quite a pain! If you decide to make this, definitely go with 1) a pan you don't mind cutting up or 2) something glass or scratch-proof.
Making layer two was pretty easy, but spreading it was a bit of a pain. Because the mixture was so warm, it began melting the bottom layer! I definitely suggest letting it cool a bit before spreading.
Layer three was BY FAR the most difficult just because it took a lot longer than I thought it would. I had to melt down the caramels on low heat so they wouldn't overcook (= become brittle), which took about a half an hour! My suggestion: melt them a bit in the microwave first.
Anyway, it looked really nice once it was spread out. I wish I would have added in a bit of extra cream in order to thin it out a bit (= easier to spread by the edges), but I think it should be okay.
The top layer was the same as the bottom layer, which made it easy and predictable! I let it cool for several hours, and then I tried to cut it! It was really tough to cut through, so I ended up making lines across the top (to make sure it would be enough pieces) and let my husband cut through it for me ;)
They candy turned out great! The recipe said it would taste like Snickers, but I wasn't actually expecting it to. It did! I think I liked them more than Snickers because they were a bit creamier ;)
