So yummy and so easy - did I mention FAST? You can make this up on the drop of a hat with things I usually have around anyway. I love the addition of the peanut butter to the chocolate since this prevents the chocolate from getting to hard when it is chilled. I scaled this recipe to be for a smaller pan and used chunky peanut butter. I used a bit less peanut butter in the topping and a bit more chocolate (personal preference). Delicious, definitely a keeper! Thanks for posting.
