I made these to take to my in laws today for Christmas. They were GREAT, although very rich! I ended up with about 38 sandwiches, so I made my filling for the sandwiches a little large, and it would have been better if the filling was smaller. They taste a bit like Reese's cups in pretzels. I had a question prior to making them, what SIZE bag of chocolate chips. It was the small size bag and I actually only used about 2/3 of that bag. I would definitely make them again, very good, very easy and very rich!! ...but I would make the balls for the filling a little smaller. I was worried about getting the SQUARE pretzels, but was able to find them at Publix. So if you want to make these, make sure you can find the square pretzels, although possibly you could do them with the real small knotted ones, although there wouldn't be much space for the chocolate to cling to.. BTW, I used milk chocolate, although a dark chocolate sounds kinda good to me!
