Instructions

1. Combine the dry ingredients (almond flour, cocoa, sweetener, baking powder) in a small bowl to ensure no clumps remain.
2. Add the wet ingredients (melted butter, egg or flax egg, vanilla extract) and whisk until a smooth batter forms.
3. Pour the mixture into a standard 12-ounce microwave-safe mug.
4. Microwave on high for exactly 90 seconds, though this may vary slightly depending on your microwave wattage.
5. Let the cake rest for one minute to set, which prevents it from collapsing or being too hot to eat.
