Vegan Brownie

4 ounces unsweetened chocolate, chopped
1/2 cup margarine, cut into pieces (like Earth Balance)
1 1/4 cups granulated sugar
2 teaspoons vanilla extract
1 1/2 bananas
1 cup flour
1/4 teaspoon salt

Melt the chocolate and Earth Balance in a double boiler. Set aside to cool.
Mash the bananas, sugar, and vanilla in a bowl until well blended and free of lumps. Add melted chocolate and Earth Balance, stir to combine. Add flour and salt until the batter resembles a loose dough (not liquidy, but not like bread dough--like the consistency of biscuit dough).
Fill a lined muffin tin with the batter until the cups are half to three-quarters full. Bake at 350 for approximately 20 minutes or until an inserted toothpick comes out clean.
