Rolo Cookies

I have made these several times and they are so so so good. Great surprise in the middle and so easy to make.
2 1/4 c. flour

3/4 c. cocoa
1 tsp. soda
1 c. sugar
1 c. packed brown sugar
1 c. butter, softened
2 tsp. vanilla
2 eggs
1 c. chopped nuts (your choice)
60 Rolo candies
4 tbsp. sugar

Preheat oven to 375 degrees. In small bowl, combine flour, cocoa, and soda; blend well. In large bowl, beat sugars and butter until fluffy. Add vanilla and eggs; beat well. Slowly add flour mixture; blend well. Stir in 1/2 cup nuts. For each cookie with floured hands, shape about 1 tablespoon dough around caramel candy, covering completely. In small bowl, combine 1/2 cup nuts and 4 tablespoons sugar. Press one side of each ball into pecan mixture. Place, nut side up, on ungreased sheet. Bake at 375 degrees for 7 to 9 minutes. Cool slightly and remove from sheets. 60 cookies.
