Peanut Butter Keto Mug Cake (Easy Keto Dessert & Snack)
Yields2 Servings
Prep Time5 minsCook Time2 minsTotal Time7 mins
 2 tbsp (28g) erythritol
 1 tbsp (15ml) unsweetened almond milk
 1 egg
 ½ tsp (gluten-free) baking powder
(Optional) Topping:
 chopped peanuts
1

Mix all of the ingredients except for the melted chocolate and chopped peanuts in a small mug or bowl that's oven- or microwave safe.
Whisk until you get a smooth and chunk-free dough.

2

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

3

Add your cake batter into a mug (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!

5

Serve with bit of melted sugar-free chocolate & chopped peanuts (optional) and enjoy while it's still warm or later when it's already cold. Both options taste good!

Instructions: Oven
6

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