1/2 c. butter
1/2 c. sugar
1/2 c. brown sugar
1 egg
1/3 c. peanut butter
1/2 tsp. vanilla
1 c. flour
1/2 tsp. baking soda
1/4 tsp. salt
1 c. chocolate chips
1 c. oats

Cream butter, sugar, and brown sugar until light and fluffy. Add egg and beat well. Beat in peanut butter and vanilla. Sift dry ingredients together and add to creamed mixture. Thoroughly mix in oats. Spread into a greased 9x13 inch pan. Bake in a 350 degree oven for 20-25 minutes.

Remove from oven and sprinkle with chocolate chips. When they have melted, about 5 minutes, spread over bars. Top with the following:

Combine 1/2 cup powdered sugar, 1/4 cup peanut butter and about 2-4 tablespoons of milk (enough to make a thin icing). Drizzle over chocolate and let bars cool. Cut in 3x1 inch bars. Makes about 3 dozen.
