Aren’t mug cakes just the most brilliant invention ever? I think the ability to produce a healthy single serve cake in 3 minutes from start to finish is nothing short of a miracle.

I have a whole bunch of low carb keto mug cake recipes on my website already. But I have to say, this one is special.

I’ve made a peanut butter brownie in a mug, and it is egg free! This means it’s supremely fudgy, and totally delicious. It makes 1 single serving at just 5.6g net carbs.

Let’s take a look at the ingredients:

Peanut Butter – Make sure it’s runny and smooth. This is absolutely essential! Hard peanut butter will result in a dry brownie. I like to use brands that are 100% peanuts. You can also use almond butter or any other nut or seed butter.

Coconut Flour – Can be replaced with 3x the amount or almond flour.

Cocoa Powder – This should be 100% unsweetened cocoa.

Powdered Sweetener – I used a powdered erythritol monk fruit sweetener blend. Pure erythritol, allulose, Splenda or Bocha Sweet also work.

Milk – Any nut or seed milk of your choice. I used almond milk.

Baking Powder – To give the brownie a nice lift.

Optional: Pinch of Salt – Either stir it into the brownie batter or sprinkle a few flakes over the top.

Optional: Sugar Free Chocolate Chips – Lily’s is a popular brand in the US. Or simply chop up a square of 90% dark chocolate such as Lindt.

How to make a sugar free mug brownie

  1. Get a mug.

The “mug” can be a proper mug or any microwavable bowl such as a ramekin. My ramekin had a diameter of 3 inches. Option to lightly grease it to prevent sticking.

2. Mix the batter.

I a small bowl, stir together the coconut flour, cocoa powder, baking powder and sweetener with a fork. Break up any clumps.

In another small bowl, combine the nut milk and the peanut butter.

Then, add the dry ingredients to the wet and stir until a brownie batter forms.

Last, fold in the chocolate chips and fill the batter into the prepared mug or ramekin.

3. Microwave.

Microwave the sugar free mug brownie until it’s done. That’s it!

Microwave timings

Microwave timings will vary according to the wattage of your microwave. Mine operates at 900 Watt.

Below are suggested timings for different power strengths:

  • 600W = low power. 80 seconds
  • 800W = 70 seconds
  • 900W = 60 seconds. 
  • 1000W = 50 seconds
  • 1200W = 40 seconds 

I first tested the sugar free brownie after 45 seconds. For all of you who like their brownies super fudgy, this may already be enough.

Also, keep in mind that mug cakes continue to cook in the hot cup after microwaving. So, don’t be tempted to overcook! 

Oven instructions

To make this single serve brownie recipe in the oven, bake at 180C (160C fan) / 350F for around 7 minutes.


Caramel swirl brownie: Stir in a swirl of sugar free caramel sauce.

Raspberry brownie: Press a few fresh raspberries into the batter.

Almond flour brownie: Use 2 tablespoons of almond flour instead of the coconut flour.

Add an egg: This makes the brownie fluffier, with a cake-like texture.

As mentioned above, any seed or nut butter can be used in place of peanut butter.

And last but not least, this keto brownie tastes incredible with a scoop of sugar free ice cream!
