Easy Sugar Free Keto Lemon Mug Cake

Ingredients:
 2 tbsp (0.5oz/16g) finely ground almond flour
 2 tbsp (0.5oz/16g) finely ground coconut flour
 2 tbsp (1oz/28g) granulated erythritol
 1 egg
 1 tbsp (15ml) unsweetened almond milk
 1 tbsp (15ml) melted butter or coconut oil
 1 tbsp (15ml) lemon juice
 1 drop lemon flavoring (optional)
 ½ tsp (gluten-free) baking powder
Optional: Lemon Icing
 2 tbsp (0.3oz/12g) powdered erythritol
 1 tbsp (15ml) heavy cream
 1 tsp (5ml) lemon juice
Instructions:
1

Add all of the ingredients except for the ingredients for the optional lemon icing into a middle-sized bowl.
Whisk until you get a smooth and chunk-free dough.
 

2

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).
 

3

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

Instructions: Microwave
4

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
5

Preheat your oven to 350 degrees Fahrenheit (180°C).
Follow the same steps as above.
Bake your mug cake for about 10-15 minutes.

(Optional) Prepare the Lemon Icing:
6

Mix the powdered erythritol, lemon juice, and heavy cream and pour it over the finished keto lemon mug cake.
 

7

Enjoy warm or cold, both options taste great!
 
 

8

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