This is an rich and delicious peanut butter-chocolate pie. It was relatively simple to make, but the results are outstanding. My family absolutely loved it. I did freeze the pie for a couple hours, but then I refrigerated it. Even with refrigeration, I think it is best to let the pie sit at room temperature for about 15 minutes for easier slicing. I did not use any additional chocolate topping - the amounts listed are sufficient. Covered, the pie seems to keep well for a couple days. I will definitely be making this one again.
