About this Peanut Butter Oatmeal Cookie Recipe, peanut butter cookies were the first cookie I made. My parents weren’t chocolate lovers (crazy, right?!) so chocolate chip cookies weren’t an option. It’s all good though, I love the simplicity of peanut butter cookies. There are some peanut butter cookies recipes that have only four ingredients. These have more than that, but they’re still easy to make. Basically, dump it in a bowl and combine it!

The addition of oatmeal gives these cookies a nice change from traditional peanut butter cookies. They’re rich and soft but the oatmeal lightens them so they’re not so heavy tasting.

If you eat just the inside of a peanut butter cup, that’s what these cookies taste like, especially the dough. So good!

When measuring flour you’ll want to first sift it, then use a scoop to fill your measuring cup. Lastly, level the cup with the back of a knife or something flat. This measures flour more accurately than the scoop and sweep method.

When you weigh a cup of flour that’s been measured the ‘scoop and sweep’ method, it’ll weigh about 5 ounces. A standard cup should weigh 4.25 ounces.

You’ll get a much more accurate measurement using the method I used above. If you want to be dead-on correct you should weigh all ingredients instead of using the cups. If you’ve ever had a heavy, dry cake or cookies the culprit may lie in incorrectly measuring the flour.

Store cookie dough in the fridge in an airtight container for 12 hours or in the freezer for up to 4 weeks.

  1. Hi Paula
    My name is Andre Thomas, I’m writing you from Atlanta, ga. I would like to ask for your advice on a meal plan for myself. My blood pressure and cholesterol are too high, the dr. says I should be on a diabetic diet, even though I’m not on any type of diabetic meds. What should I be eating and how should I eat, keep in mind that I work at night so my system is backwards. If you can advise me, I would greatly appreciate it. Thanks

  2. I’m a HUGE peanut butter fan and I could gobble down a whole plate of these cookies!! Lookin’ good! 🙂

  3. I love the combo of pb and oatmeal together, looks klike a great cookie! I want one 🙂 All month long I am featuring different holiday cookie creations for my cookie countdown to Christmas! I would love it if you stopped by to check it out! 🙂

  5. One of THE most popular cookie flavors ever—-even at Xmas. Always a winner.
