Combine first three ingredients: chocolate, margarine and brown sugar into bowl and microwave at 50% for 2-4 min, blend well.

Then add all other ingredients to the bowl, beat until well blended.

Spread into a 9x9 baking dish.

Place an inverted plate, on top of baking dish in microwave oven.

Microwave at high for 4-7 min or until done, rotating 1/4 turn after 2, 4, and 5 minutes (for microwaves without the rotating circular plate that the food cooks on).

Let cool and enjoy!
