We all loved this recipe from TOH! I came here to post but it was already posted. I cheated and used a box brownie mix (bkz I didn't have unsweetened choc), then the icing (which we really enjoyed) and the pecans and M&M's. My son doesn't like coconut so we used crused oreos. We are planning on serving this for one of our Christmas desserts. Thanks for posting!
I made this for a kids' party and it was devoured! I received lots of compliments on it. My only problem with the recipe was the amount of icing. It was extremely thin so I made a second batch. I used the toasted coconut the recipe originally called for and mini chocolate chips in place of the M&M's. Very easy to put together with impressive visual and flavor results. Thanks!
