1 c. firmly packed brown sugar
1 c. butter
1 c. chopped pecans
Graham crackers (enough to cover a cookie sheet)

Preheat oven to 350 degrees. Combine sugar and butter in a saucepan; bring to a boil; boil for 2 minutes. Remove from heat and stir in chopped pecans. Pour over graham crackers, which have been placed close together on a cookie sheet. (Crackers should be close enough to form a solid sheet.) Spread mixture evenly over graham crackers. Bake 10 minutes. Cool slightly and cut into squares.
