In a 4 oz ramekin, add the egg, cocoa powder, and sweetener. Stir to incorporate all the ingredients together fully. The mixture should be smooth with no lumps.
Step 2
Transfer the ramekin to the microwave and cook for 45 seconds. The soufflé should rise slightly and not be fully cooked through the bottom. Slightly undercooking will result in a thin layer of sauce at the bottom of the ramekin, almost like hot fudge. Serve immediately.
