Favorite Cookies

I could eat an entire batch of these cookies because they are so delicious and they are kind of healthy because of the peanut butter and oats, right? I will keep telling myself that:)

I love these cookies because I always have the ingredients on hand. You don’t need any special ingredients, but that doesn’t mean the cookies aren’t special, they are VERY special. Every tine I make these cookies they get rave reviews by family and friends. They are just a REALLY good cookie, a classic!


Here are a few tips that will guarantee cookie success every single time!

  • Use old fashioned oats, not quick oats for this recipe.
  • Don’t skip the cinnamon, it gives the cookies an extra hint of deliciousness.
  • For this recipe, I don’t use natural peanut butter. JIF or Skippy or a similar brand works best. I use creamy peanut butter, but chunky would be good too.
  • I love the simplicity of these cookies but feel free to add in chocolate chips if you wish.
  • Don’t over bake the cookies. Remove from the oven when the edges are set but the middles are still soft. They will finish baking on the baking sheet. You want them to be soft and chewy.
  • These cookies will keep in an airtight container on the counter for up to 4 days. These cookies also freeze well. Place cooled cookies in a freezer bag or container and freezer for up to one month. They are good frozen or you can thaw them before eating.

The next time you need a cookie fix, make a batch of Peanut Butter Oatmeal Cookies. These simple cookies are always a winner!

    I’m eating these warm and fresh out of the oven right now and wow so yummy!! I used Costco organic creamy peanut butter cold out of the fridge and it worked very well just in case anyone else uses their pb 🙂 Thanks so much!

    These are amazing it will call for a lot of ingredients that you have laying around in you house some are unusual._.) But I can deal with that I do recommend this recipe:)

    1. They have a finer texture and aren’t as hearty. If that is all you have, you can try it, but I always use old fashioned oats.

    2. Did you bake them with quick oats? It’s all I have and am curious how they turned out? Thank you!

  3. These cookies are so amazingly good! And because I’m such a peanut butter freak I doubled the recipe and added a cup of peanut butter chips

  4. 5 stars
    Great cookies, not too dense and nice texture. I added more cinnamon than called for, used coconut oil instead of butter, and used about 1/4 cup less of total sugar. They came out great and would make them again 🙂

  5. I would like to add raisins to this – a friend requested oatmeal peanut butter raisin cookies and I want to make your recipe it looks amazing. How much raisins should I add. I don’t want to mess them up.

    1. I would start with a 1/2 cup. Stir them in and if you want to add more you can. Enjoy!

    Delicious! I was pleasantly surprised with this recipe. I was trying something new, oatmeal cookies aren’t my first choice, but these are definitely high ranking now! The texture is very soft. I actually used less brown and white sugar ( about 1/3 instead of 1/2 ) and they tasted not too overly sweet but noticeable!

    I made these today! I ran out of butter so I used mayonnaise; followed your recipe but used a little more brown sugar than white; my peanut butter was skippy honey blend. These cookies are superb son gobbled them up and my wife loves them. (Next time I’ll use butter to see the difference. Thanks for the recipe.

    I made these cookies last night (I’m an insomniac) and sent some to my friends work place. They are freaking awesome. Thank you so much for such a tasty recipe!

    My family & I absolutely LOVE these cookies! I’ve made them several times already. I now use Bob’s Red Mill Gluten Free 1 to 1 flour & they are just as good as with regular flour. I also add Mini Semi-Sweet Chocolate Chips. SO GOOD! Cant wait to try more of your recipes!

    Thank You

    10/10, crazy good. I like using 1/4 cup butter, 1/4 cup coconut butter for the flavor, aaaaand…. adding in a little cardamom and coriander. This is probably the first time my cookies haven’t turned out rock hard, the texture is absolutely perfect. Thanks!

    These were a scrumptious and necessary baked good in my home during school shutdown!!! Kept grandma and kiddos happy. We got A LOT of peanut butter and oatmeal from the school lunches and food bank, so this recipe was perfect! I dub thee Pandemic Peanut Butter Oatmeal Cookies!!

    Literally my favorite cookies ever. I am making a half batch right now. Easy to halve, just beat an egg and add half of it to recipe! (Otherwise I’d eat too many.) Thanks!

    I made a batch today. Cut the sugars in half and they were still plenty sweet. Very nice cakey texture and lovely flavor. I will make them again.

  14. 4 stars
    Pretty good, a bit too sweet for me – you can feel the sugar crunch when you bite them. Kids loved them of course. If I made them again I’d probably half the white sugar.

  15. These are undisputably the best family all raves about them. Sometimes I change it up with large raw suger(the Indian kind that doesn’t melt). Makes them a bit crunching on the outside and chewy on the inside…

    This recipe is amazing! I kicked it up a notch by browning the butter. Also tossed in a tablespoon of chia seeds to make them extra healthy and finished them off with a drizzle of fudge. Muy bien!

  17. I followed the instructions and they end up balls and don’t spread out at all. Lumpy little things. Taste just fine, they just don’t flatten out. Second batch I pre-flattened them before putting into the oven and they came out okay, a bit dry but great with a glass of chocolate milk or a cup of tea.

    Awesome cookies! My family loves them! I used quick oats and natural peanut butter and also added walnuts! I’m very pleased and will definitely use this recipe over and over again! Thank you!

  19. 5 stars
    These are great! I used crunchy pbutter because my inlaws keep buying it for the kids but they don’t like crunch on PB&J sandwiches. haha. So I had a lot to use up! I also used quick oats and added dried cranberries. YUM! Thank you!
