Oh my GOODNESS! This is a FABULOUS dessert!!!!! I only had dark brown sugar and light corn syrup, but I don't think it altered the taste much, if any. I didn't get a picture of the entire pan, because pieces were stolen before it ever even cooled! These are fabulous as is, but if you heat a bar in the microwave a few seconds, top with vanilla ice cream and a drizzle of chocolate syrup, you have a dessert tasty enough to be served in a restaurant! I never knew something so delicious could start with a mix. Thanks for posting a SURE WINNER Kitten!
