Chocolate Fluffernutter Mug Cake

Chocolate Fluffernutter Mug Cake
Ingredients
4 tablespoons white sugar
4 tablespoons self-rising flour
3 tablespoons cocoa powder
3 tablespoons melted butter
3 tablespoons peanut butter
3 tablespoons milk
1 egg
marshmallow fluff for topping
Method
1. Add all ingredients into a LARGE MUG. Mix very well with a fork. Microwave on high for 1 1/2 to 3 minutes. Cooking time will vary depending on your microwave wattage.
2. The way I can tell if mine is done is because it rises alot then settles a bit. Right after it starts to settle, I know it’s done. Check with a toothpick for doneness. Cake is suppose to be ooey and gooey, just not runny.
3. Top with a heaping tablespoon of marshmallow fluff.
