I've been making these cookies since I could reach the stovetop to stir the pot by standing on a chair. My Dad brought the recipe home from the Navy after the Korean War. No bake and easy to make!
1 stick butter (1/2 cup)
1/2 cup milk
1/4 cup cocoa powder
2 cups sugar
1/2 tsp vanilla
1/2 cup peanut butter
3 cups quick oats
In a medium size saucepan melt the butter, add milk, cocoa and sugar. Heat over med-high heat stirring constantly until mixture comes to a rapid boil, then continue to stir and boil one minute. (Timing at the point is important to the finished product. To much boiling will result in dry cookies; to little and they won't set up.)
Remove pan from the heat; stir in the vanilla and peanut butter until mixture is smooth. Add oatmeal and stir until well combined.
Immediately pour into a lightly greased 9X12 pan (or spoon onto wax paper in individual size cookies). Allow to cool completely. Cut into squares to serve.
