Chocolate Peanut Butter Pie

"I really love this recipe, which I found on the web. It's so fast, simple and easy, with very few steps, and great for the summer or busy days because it's a no-bake pie (the ingredients are melted right in the microwave. It's also a bit different than most similar recipes, as it uses marshallows instead of heavy cream or whipped topping. I've often made it when I needed something last-minute, as it's ready to serve with just a few hours of chilling. It's great with some whipped topping or whipped cream, or even just on its own. One time I was short on chocolate chips and used 1/2 cup instead of a full cup, and added about a 1/3 cup of unsweetened cocoa powder, an extra tablespoon of sugar, and about 1/2 tablespoon of butter to make up the diffference, and it still came out great. Since then, even with the full cup of chips, I still add a little cocoa powder, butter and extra sugar for the extra bit of chocolate flavor, but that's compleely optional. It's wonderful without those additions. I hope you enjoy it as much as we have."
