I can't believe I am the first to review these! After converting the ingredients and coming as close as I could to the correct measurements these were so tasty! Instead of using the muffin tins though I decided to use a 9x13 baking pan and do it that way. Muffin tins and I don't usually do well together. :) For the candy bars I used Reeses Peanut Butter cups and I couldn't stop licking the batter! I think a chocolate base would be very tasty as well. Made for the Aussie/NZ recipe swap.
