Peanut Butter Mug Cake

My peanut butter mug cake is an easy and tasty way to make yourself a little treat. Simply add all cake ingredients to a mug, stir to combine, and microwave for 60 seconds. Mix up the frosting ingredients and drizzle over your mug cake, all that’s left is to enjoy!

If you are low carb simply swap out the maple syrup for Lankanto Monkfruit. This mug cake is 12 carbs with the chocolate chips and only 4 if you leave out the chocolate chips!

I topped mine with the frosting included in the recipe and a few extra Enjoy Life chocolate chips, very yummy. My husband is not gluten or dairy-free and he liked it too!
