"I have made these several times now, co-workers can't get enough! I used a can of Dulce de Leche instead of the sweetened condensed milk and only used a stick and a half of butter. Wrapped each one in wax paper like salt water taffy, worked great. I have put them in the freezer, bring to room temperature before eating. Toppings: Gold Fish crackers in 'brownie' flavor, also in 'french toast' flavor. Put them in a food processor for crumbs. I've also used graham crackers with some coconut thrown in and a few mini chocolate chips. These are especially good roasted over an open flame :) Today I ran out of crumbs to finish off the caramel so I used some 'Great Grains' cereal with oatmeal/raisins and pecans......seriously, you could use anything to dip these in. They're just too much fun and good!"
