Rolo Cookies

This recipe is from my friend (and a great cook) Judith.

2 1/2 cups flour
3/4 cup unsweetened cocoa
1 teaspoon baking soda
1 cup sugar
1 cup brown sugar
1 cup butter
2 eggs
2 teaspoons vanilla
48 Rolos
2 tablespoons sugar

Combine flour, cocoa and soda and set aside. Beat sugars and butter until well-blended; add eggs and vanilla. Add dry mixture and blend well. Shape cookies into small balls. Press Rolo into center of ball and cover with dough. Roll cookie in sugar. Bake on ungreased cookie sheets at 350 degrees F. for 8 to 10 minutes, until tops of cookies are slightly cracked. Cool on racks.
