The only change I made in the recipe was I used Wilton Christmas Sprinkles and Holiday M&Ms instead of the peppermint candies. Don't add the M&Ms in too quickly or they will melt. I also added...
It is easy to make only I put my popcorn in a brown bag after popping and pour the chocolate and nuts over the popcorn then shake until coated. It makes for a lot less mess.
We left out the peppermint, because we were just looking for the right amounts of almond bark to use. It's sweet, it's salty - what more could you ask for? :D
