A recipe from fatfree.com:

Fat-free Chewy Chocolate Cookies
1 1/2 c. flour
1/2 c. sugar
1/2 c. unsweetened cocoa
1/2 tsp. baking soda
1/2 tsp. salt
1/2 c. Karo (light or dark)
3 egg whites

Spray cookie sheets with cooking spray. In large bowl, combine flour, sugar, cocoa, baking soda and salt. Stir in corn syrup and egg white until blended (dough will be thick and slightly sticky). Drop by rounded teaspoon onto prepared cookie sheets. Bake at 350 degrees for 7 to 9 minutes or just until set (cookies will be soft when pressed). Do not overbake. Cool on rack.

I add less than 1 tsp vanilla extract for flavor. If you really want the 'pure chocolate' taste, omit using vanilla extract!
