Very tastey! I followed some ideas of the others and added some of the walnuts to the mixture. I only found a 12 oz. box of Nilla Wafers so that's all I used. Chopped the Nilla Wafers and the nuts in a grinder for my own sanity. I also made sure to refrigerate the chocolate mix before forming the balls. I used a "tiny ice cream scoop" with the release handle and it formed perfect shapes. I dropped the balls into a bowl of confectioners sugar and nuts and swirled them around for a good coating. I fit about 4 into the bowl. Worked great and not too messy. I will make these again!!!!
