I've made other desserts like this that turned out with a hard crust, but this turned out soooo soft. Be careful when pouring the topping mixture over the marshmallows, or you might cave in the middle. I had marshmallows coming up the sides of the pan, so next time when I pour on the topping, I'll do it slowly and in spoonfuls along the edges first then work my way in. Also! The bag of peanut butter chips wasn't enough, so I added peanut butter to that mixture and a little more corn syrup too.



This dessert is super rich and has great flavor! I've made it many times and my best advice is to LIBERALLY spray the sides of your baking pan to prevent the marshmallow from becoming a permanent fixture. I also spray my knife before attempting to cut this dish. Also, I've found I'm too cheap to buy the necessary 2 cups of peanut butter chips and just use a standard 12 oz. bag (which is about 1.5 cups. It works just fine. Enjoy!

What a fun recipe! This is definitely a bar recipe and not a cake. I used 1/2 cup more marshmallows than it called for (personal preference). Awesome taste, much better than a Payday candy bar. I highly recommend this recipe, it is rich and chewy and yummy!
