Break the chocolate into pieces and place in a large microwaveable bowl with the margarine. Microwave at 20-second intervals until margarine is melted. Stir until chocolate is completely melted and smooth.

Stir in the sugar, then add the eggs and vanilla. Add in flour and mix well. Cover bowl with aluminum foil and refrigerate for one hour.

Preheat oven to 350 degrees Fahrenheit (180 degrees Celsius). Line two baking sheets with Gefen Parchment Paper.

Scoop dough into one-inch balls (a small cookie scoop works great) and place two inches apart on the baking sheets. Bake for nine minutes on the center rack of the oven. Cool completely before removing from baking sheet.
