I found these cute mummy cookies on this site, and I had to make them (even though I think it is totally blasphemous to cover something so delicious as an Oreo cookie with (*cringe*) white chocolate). You need to see the ones she made though, they are much, much cuter!
The other cookies are just 2 Ritz crackers with peanut butter in the middle, then dipped in chocolate and drizzled with melted butterscotch chips. There is nothing really Halloweeny about these ones except that I thought that the chocolate and butterscotch looked like orange and black.
In all honesty, I couldn't even eat the mummy ones, I pawned them off on Luke. They are cute, but I just can't eat that white chocolate. But the other ones are pretty tasty, and they look cute together! =)
