1/2 cup packed brown sugar
1 tsp vanilla
1/2 cup all-purpose flour
1/2 cup quick cooking oats
1 cup semisweet chocolate chips
1/2 cup chopped pecans
Preheat oven to 375 degrees.
Lightly grease an 11x7-inch baking pan; set aside.
In a mixing bowl, cream the butter and brown sugar; beat in the egg and vanilla. Add the flour and oats, mixing well.
Pour into the prepared baking pan and bake at 375 degrees 15-20 minutes or until lightly browned. Remove from oven and cool on a wire rack for 3 to 5 minutes.
Sprinkle the chocolate chips over the warm bars; allow to melt then spread over the entire top. Sprinkle with the chopped pecans (or other nuts of your choice).
Cut into 18 bars.
