The oatmeal makes all the difference. These are the VERY BEST! They vanish quickly.


  1. In large bowl mix the butter, shortning, sugars and peanut butter.
  2. Add eggs one at a time.
  3. Blend flour, soda and salt then add to sugar mixture.
  4. Then add oats.
  5. Form into 1 1/2 inch balls (no need to press with fork like usual) These come out perfectly round Bake 350 degrees for 12 minutes.

Yummy! Yummy! Yummy! We made this recipe with many modifications and it was still delicious! We did all butter, no shortening, decreased white sugar to 1/4 cup, used a combo of whole wheat and regular flour, added vanilla, chocolate chips and pecans. Beautiful cookies and most delicious. Also, very easy recipe. We'll be making this one often!

I have to agree, these are The Best Peanut Butter Oatmeal Cookies! I chose this recipe based on its high rating, and that it seemed to stand up to other's modifications with good results. After researching tips on substituting Coconut Oil for other fats (because I don't have any shortening), and oatmeal for flour in baking (it was suggested that 1/3 of the flour can be substituted with oatmeal). I used 1/2 c unsalted butter and 1/2 cup Coconut Oil, creaming that with the sugars before mixing in the Peanut Butter. I decreased the amount of flour to 1 cup, and only used a pinch of Kosher Salt (I don't have any regular table salt), and increased the oatmeal to 1 1/2 c. Using a measuring TBSP to scoop the dough, I baked the rolled balls on a foil lined sheet at 350 for 12 minutes, then allowed them to set for a couple minutes before playing. While the recipe suggests it makes 24 cookies, I made 5 Dozen, yes SIXTY cookies! With that being said, I think this would be a terrific recipe for any large function, holiday gifting, or bake sales. So simple and delicious!!

These are the best cookies. They disappear very quickly. I reduced the sugar by a quarter cup and added 1/2 cup more oatmeal because they were too sweet for me. All I can say is YUMMY!!!
