These were a great addition to our cookie tray! I will use small mrshmllws next time as I wound up cutting the big ones into 1/4 size so it was easier to ice over. The icing was very dry & did not come together with the msrments listed so I just added more cream to get the right consistency. It turned out great! I used Hershey's cocoa and a 1in scoop and cooked at times listed. They came out soft but firm enough to hold up. The kids & I agree that the batter tastes like brownies and the finished cookie was a huge hit!
