These Microwave S’mores Mug Cakes are so easy even Kenya and Chloe made them on their own. You just mix the batter in a bowl and layer the marshmallows and chocolate in a good sized mug. Press one minute on your microwave and you’ll enjoy one of the most delectable desserts you’ve ever tried. It’s sweet, gooey with a deep chocolate brownie inside sandwiched between a graham cracker crust and gooey marshmallows you won’t be able to resist.
