Flourless Peanut Butter Mug Cake

This mug cake is the perfect solution for when you want just a little something sweet.  Chocolate and peanut butter, gluten-free, and ready in less than 5 minutes, this mug cake could be your new dirty little secret.

Okay, I’ll be the one to say it.  Working at home, kids at home, no getting out for those brief times that are just for you  (like hair, nail appointments, going to the gym) is hard, challenging, and exhausting.  

We’re told that this is a special time to reconnect as a family, slow down, and enjoy these moments.  It’s a beautiful sentiment and I think most of us feel that way to a point.

But, when you spend the whole day caring for your family, being teacher, coach, dance/sports instructor on top of trying to work, keep the house pristine, and worrying about finances, uncertainty, etc., you need to take a moment and nurture YOU – even if it’s just for 10 blissful moments.

That’s where this ridiculously simple and delicious mug cake comes in!  You can literally make this for yourself while the kids are outside for the ten minutes before their attention span shifts to the next activity.  And it’s probably better than drinking at 10 am.  

TIPS FOR MAKING MUG CAKES

  • Since this recipe has no flour, it is crucial to the final product that you thoroughly mix the egg into the other ingredients.  You don’t want streaks of scrambled egg. You also want to beat some of the air into the mixture, so that it rises well.
  • You can use granulated sugar, but the brown sugar adds another bit of moisture.  
  • If you use regular chocolate chips, they may not get soft and gooey.  It will still taste amazing, but you won’t get the little pockets of chocolate.
  • By adding water to the top of the cake before microwaving, you will keep the top from becoming overdone and rubbery.  The water will evaporate while cooking but leave a luscious, moist top.

VARIATIONS ON THIS RECIPE

  • You don’t have to use peanut butter.  Try Nutella, cookie butter, or any nut butter.
  • Try adding toffee chips in place of some or all of the chocolate chips.
  • White chocolate chips or even cinnamon chips would work well in this mug cake.
  • Want to cut a bit more calories?  Swerve sweetener works very well in this recipe.
  • Feeling the need to splurge?  While the cake is still hot, unwrap and push a round chocolate, filled truffle candy into the center.  Boom! Molten lava cake for one.

The only equipment this recipe uses, besides a microwave, is:
