I found a Molten Chocolate Cake recipe and made it low carb. I can't believe it has so few ingredients and yet is so delicious. You could even serve this to company. I converted this into one easy to make serving.

1 tsp. butter
3 squares Lindt Chocolate bar (75% cocoa)
1 egg
1 1/2 tsp. Davinci vanilla sugarfree syrup

Melt butter and chocolate in a large mug for approx. one minute in the microwave. Add one egg and vanilla syrup. Stir vigorously with a fork. Microwave the mixture for one minute. I like to eat this straight out of the mug, but if you want to serve this to company you could run a knife around the edge and turn it upside down, lifting it out onto a plate. Dust with powdered Stevia if desired.
