I use to make these all the time with my step-gramma when i was a kid. We would make tons and tons of cookies all year long and they are so tastey! I got this recipe out of the Delaware County Historical Society Cookbook, From my hometown, in Iowa.
1C Brown Sugar
1C Peanut butter
2t baking soda
4 1/2 C Oatmeal
1C M&M (i love using peanut M&M's)
1C chocolate Chips (I never use these)
Mix ingrediants in order given. Drop by teaspoon on ungreased cookie sheet. Bake 12 minutes on 350 oven. Don't overbake! This recipe takes NO FLOUR!
