2/3 c. butter
1 c. brown sugar
3 tsp. vanilla
4 c. quick-cooking rolled oats
1 (6 oz.) pkg. chocolate chips
2/3 c. peanut butter

Preheat oven to 350 degrees. Cream butter; blend in sugar, corn syrup and vanilla. Stir in oats. Spread into greased 9x13 inch pan. Bake 15 minutes. DO NOT BAKE ANY LONGER, EVEN THOUGH BARS MAY NOT LOOK COOKED.

Let cool. Melt chocolate chips and peanut butter over low heat and spread over oat mixture. Refrigerate until quite chilled. Cut into bars.
