Reese's Peanut Butter Cups: Peanut Brittle
These are pretty great, but the flavor is pretty hard to describe. The center is simple enough - it's a crunchy peanut butter cream, but the outer shell has a smoked vanilla caramel flavor. They don't really remind me of peanut brittle, but they're very tasty.
I was only able to find them in a miniatures bag, but this is the kind of product that could sell year round if they came up with a non-seasonal way to market them. If you don't mind the fact that they're not made of chocolate and you find a bag while your out Christmas shopping, give them a try. Just don't go into it expecting anything that resembles peanut brittle.
