Preheat oven to 350F. In a mini-food processor, pulse the dark chocolate pieces until they are crumbly. (For an even darker chocolate flavor, you could try using unsweetened baking chocolate instead of the dark chocolate!)
Next, add in the Stevia Baking Blend, molasses, cocoa powder and vanilla. Pulse together until you have a grainy, sand-like texture.
Now it's time to melt it all together! Add 1 Tablespoon of very hot water to the mixture, then process it again, until it's thick and melt-y. (I actually boiled some water in my teapot, to be sure it was HOT as possible.)
Finally, add the egg and chopped butter into the food processor, and blend until smooth and creamy!
Divide the batter evenly into two individual-sized ramekins, then place the ramekins in the middle of the oven, and bake for 15-20 minutes at 350F, until the tops begin to crack, and a toothpick poked in the center comes out clean-- perhaps with a crumb or two.
Allow the cakes to cool completely on a cooling rack, or place in the fridge to cool faster. Serve at room temperature.
