Measure out your powdered sugar in a medium sized bowl, set asided. On Medium heat melt the butter and the peanut butter. DO NOT LET IT BOIL! When totally melted pour it into a medium sized bowl. Using a hand mixer add your powdered sugar A LITTLE AT A TME. You have to eye ball it to call it done. You are looking for a cookie dough texture. You want it to stick together but not break into small clumps. I generally take some and roll it into a ball, you don't want it to stick to your hands, but you don't want it to crumble either. When you have it the right consistency you pour it into a 13"x9" in pan and pat it out evenly. You don't have to let it set up, it is ready to enjoy!
You have to play around with this receipe a little bit to get it to come out right. Once you do you will find that it tastes just as good as the marshmellow cream receipe but with half the time and effort! This is the perfect last minute something something to take to a party or make for those mornings when your child says "Mom I need something for my school party today"! I make this for my husband to take to work for when they have clients come in. I never have any that makes it's way back home. The clients usually end up taking some for the road!
