Preheat oven to 325 degrees F. Spray a 9x9-inch baking pan or a mini-muffin pan with non-stick baking spray; dust with granulated sugar on all sides.
In a double boiler or in a bowl set over a pan of hot water, melt the chocolate; set aside to cool. Learn different techniques for How To Melt Chocolate.
In a small bowl, sift together the flour and the salt. Fold in the flour mixture into the melted chocolate until well blended. Add vanilla extract and chopped nuts (if desired). Spread or pour batter into prepared baking pan or min-muffin pan.
Bake 20 minutes or until edges are firm (center will be soft). Remove from oven and cool 30 to 60 minutes on a cooling rack before removing from muffin pan or cutting into 1-inch square pieces.
To serve, place each chocolate brownie into a candy cup.
Yields 24 bite-size pieces.
