Forget the potholder and cakes from the oven—grab a spoon and dig into the slow cooker for a gooey, fudgy, peanut buttery treat, tempting you right from your kitchen counter! All you need to make this is some flour, brown sugar, baking powder and soda, chunky peanut butter, sour cream and butter! Then you should add plenty of chocolate chips and dump it into your slow cooker.
