In a wide mouthed coffee mug, combine your coconut flour, almond meal, protein powder, sugar replacement, baking powder and salt. (or other microwaveable safe mold, of some kind. (I like to grease my mug first, but I don't think it's necessary )) Mix in your egg, melted butter and vanilla. Microwave on high for 60 seconds, (90 seconds if using a weaker microwave, or if you've added lots of other ingredients, like nuts, frozen berries, etc.) Eat and enjoy !
