How to Make Peanut Butter and Chocolate Keto Mug Brownies

Making these mug brownies is quick and easy. It should only take about one minute to prep your batter and then an extra minute to microwave your brownie.

  • Whisk the egg and Stevia. Add a single large egg and a low carb sweetener like Stevia into a small bowl and whisk together.
  • Add the peanut butter. Add the creamy natural peanut butter (ensure you’re using a brand with no salt, sugar, or palm oil added) and mix to combine. Add the cocoa powder after.
  • Fold. Fold in the sugar free dark chocolate chips.
  • Microwave. Divide the mixture between 2 microwave-safe ramekins and microwave on high for 50-60 seconds or until a toothpick inserted into the center comes out clean.
  • Serve. Serve warm.

How to Keep Your Mug Brownies Moist and Gooey

Since you’re making these mug brownies in the microwave, here are some tips to make sure that your mug brownies are always turning out perfectly moist and gooey:

  • If your mug brownies are constantly turning out dry, then you may want to consider adding a single tablespoon of water on top of the mug cake mixture before microwaving. It will evaporate while cooking, adding a bit of extra moisture to the brownie.
  • If your mug brownies are coming out of the microwave and they’re still wet, then keep microwaving them in 5-10 second intervals until the brownie is only slightly sticky. It should also still look a little bit wet in the center.
