Healthy & Sugar-Free Keto Mug Brownie (Low Carb)

What You'll Need:
 2 tbsp finely ground almond flour
 2 tbsp baking cacao powder/ dutch processed cacoa powder
 3 tbsp granulated erythritol
 1 egg
 1 tbsp almond milk
 1 tbsp melted butter or coconut oil
 ½ tsp (gluten-free) baking powder
 (optional) flaky sea salt or chocolate chips
How To Make This Keto Mug Brownie:

Add all of the ingredients except for the flaky sea salt/ chocolate chips into a middle-sized bowl.
Whisk until you get a smooth and chunk-free dough.


Grease your microwave-safe mug or ramekin with cooking oil that doesn't have a strong taste (I like to use coconut oil, butter or avocado oil).


Add your cake batter into your mug or ramekin (the mug should be at least double the size of the mixed ingredients).

Instructions: Microwave

Microwave for about 1-3 minutes.
(The cooking time in your microwave may vary heavily depending on what microwave and what settings you're using.

A broad rule of thumb: Approx. 1 Minute at 1200 Watt and more like 2-3 minutes at <600 Watt.

If you don't know the Wattage power of your microwave I'd recommend baking your mug cake for a shorter time period (60 seconds) first and continue baking for a few more seconds if needed.
This will avoid that the mug cake dries out.
You can test if your mug cake is completely cooked by pricking the center with a toothpick - if it comes out "clean" it's ready!

Instructions: Oven

Preheat your oven to 350 degrees Fahrenheit (180°C).
Follow the same steps as above.
Bake your mug cake for about 10-15 minutes.
You can test if your mug cake is completely cooked by pricking the center with a toothpick - if it comes out "clean" it's ready!


(Optional) Sprinkle a bit of flaky sea salt or chocolate chips (or both!) on top of the mug cake for the final touch!


Enjoy warm or cold, both options taste great!


Cover with plastic wrap and store for up to 2 days in your fridge.
