This keto mug cake is one of my favourite easy treats. It is like a single serve vanilla pound cake. Perfect for a spontaneous sugar free dessert straight out of the mug - or turn it out onto a plate!
Stir together the dry ingredients in a bowl - almond flour, coconut flour, baking powder, sweetener. Take care to break up any lumps.
In a second bowl, whisk the egg using a fork. Then add the melted and cooled butter plus the vanilla extract and whisk until combined.
Add the dry ingredients to the wet and stir until a smooth batter forms.
Grease a mug or ramekin with butter and fill in the batter. Microwave for 80 seconds @ 900W. (Baking times for different power levels are included in the notes below).
Enjoy straight from the mug or invert onto a plate.

Notes
2.5g net carbs per serving. Makes 1 serving. My microwave operates at 900W and my cake took 80 seconds to cook. Here's a quick overview of recommended baking times for this cake recipe:
600W = low power. 100 seconds.
800W = 90 seconds.
900W = 80 seconds.
1000W = 70 seconds.
After these times, check whether the cake is done. If it's still undercooked, add increments of 10 seconds. Choose a cup or ramekin that holds a minimum of 200ml. Otherwise the dough will overflow as it rises.
