4 c. oatmeal
1 c. brown sugar
1/4 c. corn syrup
2/3 c. melted butter
1/4 c. chunk peanut butter
1 tsp. vanilla

Mix and pat into a 9x13 inch pan. Bake at 400 degrees for 12 minutes, just until edges are brown. The middle will not be set but the bars will firm up as they cool. Do not over cook. Cut the bars while warm; let cool in the pan.
