I have worked in a child abuse prevention center for 15 years and have served 75 children running the kitchen by myself-shopping, ordering, menu planning, cooking dishes, etc. Having this freedom has allowed me to create yummy and unique meals for kids of all ages. I have been making these delicious cookie bars for 20 years for work and my family.....at work the recipe is quadrupled but this is the home version. It has come by many names but one child did refer to them as "Chocolate covered hash browns" and that name stuck at the center.
Butter a 9 by 13 inch pan. In a large bowl, mix the oatmeal, brown sugar, butter, vanilla and corn syrup. Spread the mixture into the prepared pan and bake 15 minutes. Cool for 10 minutes. Cut into bars.
For the Frosting: Combine chocolate chips and peanut butter in a double boiler and melt. Mix well. Spread on baked and cooled cookie bars. Refrigerate until frosting hardens.
