Keto Peanut Butter Mug Cake Recipe! This low carb mug cake is so easy to make. Literally this mug cake takes ONLY 1 MINUTE to make, requires ONLY 4 INGREDIENTS, and has ONLY 6 NET CARBS. Seriously, this is the BEST cake you will ever make in the microwave, AND not only is it flourless, but it's keto friendly too!

  4. Add the batter to the ramekin 
  5. Microwave for 30 seconds to 1 minute

Mug cake cook times will vary. My microwave is 700 watts, and turns out perfect at a 1 minute cook time. Make sure you adjust the cook time depending on the power of your microwave.
