1 Tbl Erithrytol

1 Tblspoon of sugar free vanilla syrup
1 Pat of butter (about 1.5 tsp)
Some bits of chocolate (off a dark, low sugar bar... probably .5 an oz)
1 egg

Put the dry ingredients in a microwaveable small bowl (sweetener, cocoa) and mix. Crack an egg on top. Carefully mix into the dry ingredients. The cocoa tends to go everywhere so mix carefully at first. I use a fork. Add syrup and mix in.

When everything is mixed, drop the butter in the center along with the chocolate.

Microwave carefully. You don't want to overcook. In my microwave, it is about 45 seconds. The center will be gooey, the butter melted, the chocolate melted, and it will be firmer towards the outsides.
