Keto Mug Brownie

This decadent, chocolatey keto mug brownie is the best and easiest way to satisfy a sweet craving. Warm, indulgent chocolate brownie goodness, made with keto pantry staples and ready to eat in just a few minutes!

What We Love About This Recipe

1. This keto mug brownie is rich and chocolatey and the perfect single-serving sweet treat.
2. It’s super easy to make and it comes together so fast. A couple of minutes to melt the butter, a couple of minutes to mix the ingredients together, and then another minute or two to “bake” the brownie.
3. If you’re following a keto way of eating, odds are good you’ve got all of these ingredients on hand already. They’re keto pantry staples! Of course, you’re welcome to substitute a different sweetener if you like another one better than Swerve.

Chef’s Tips

• Don’t over-microwave the brownie. Did you ever have those Kid Cuisine TV dinners? The ones with the chocolate brownie for dessert? Do you remember the texture of those brownies if the tray was microwaved too long? Rock hard. No saving it. The most disappointing brownie ever. Yeah, that’ll happen here, too, so watch your keto mug brownie closely.
• It’s a totally optional step, but greasing the inside of the coffee mug with a little butter or cooking spray can help make clean-up a little easier. If you don’t want to do that, or if your mug is too small to make it possible, just soak the mug in hot, soapy water and any left-behind brownie will wipe off easily.

Instructions

• Place coffee mug in microwave. Microwave batter at 100% power 60 seconds or until batter is "baked" into fluffy brownie.
• Once brownie batter is fully baked, remove mug from microwave. Top with keto whipped cream or keto ice cream if desired and serve warm.

Notes

• Greasing the inside of the coffee mug is totally optional but can make clean-up a little easier.

 

“How is This Recipe Keto?!”

Keto is based off of net carbs, not total carbs. To calculate net carbs, use this formula:

(Total Carbs) – (Fiber) – (Erythritol) = (Net Carbs)

So for this brownie, using our approximate nutrition information, the numbers would come out to:

31g – 8g – 18g = 5g net carbs
