Peanut butter mug cake is a soft, moist and fudgy peanut butter cake made in a mug. This peanut butter microwave cake can be made in about 3 minutes using a handful of ingredients.
If you would like to add chocolate chips or mini peanut butter cups or any other mix in, do so now. I like to mix a few in and also top the peanut butter cake batter with a few more.
