Easy Peanut Butter 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!

Tips for Making Peanut Butter Oatmeal Cookies

  • 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 substituted ground oats for the flour due to a wheat allergy and these are great cookies. Wonderful flavor with the cinnamon.

    1. Mine also crumbles and did not flatten.. lol , I am a professional chef in the industry 35 years.

      I tried recipe again because ingredients are wonderful.. The second time I followed recipe as instructed, The only change for me was flatten ball to thick disc ” We loved these cookies yum”.. indeed the cookies are crispy but chewy so good.. Well done recipe bravo.

    3. Mine too. Only change I made was using honey instead of sugar, but I didn’t use nearly enough honey maybe? The dough seemed so gooie I thought I was going to have the opposite effect.

  2. Tried these today and LOVE them! My batch came out just as pictured and taste amazing.
    I use a gas oven and followed the recipe exactly including letting the cookies rest on the pans until they came off clean.
    Fantastic cookie outside light crisp with the even texture of moist chewy yumminess throughout the entire cookie. Thank you so much for this recipe I will make these again!

  3. These cookies are fabulous, I had to repeat them several times. I did however tweak the recipe a bit: whole spelt flour instead of all-purpose, flavorless coconut oil instead of butter (just because the butter was hard and I would have needed to wait for it to soften, but it works great!), and just some xylitol instead of so much sugar (we went off sugar and use very little sweeteners at all). They come out really yummy and almost guilt-free!

  4. Added 1/4 c chia seeds, 4oz butterscotch chips, substituted stevia for white sugar, added walnuts. Yummy!

  5. I just made the Peanut Butter Oatmeal cookies today. I followed the recipe exactly and they turned out perfect and tasty! I will make this again.

  6. I made these cookies last night and followed the recipe exactly. They were amazing! My husband and son nearly ate them all!

    I need these to be firm and crunchy. I want to fill them with marshmallow whip and dip in chocolate. What do I need to do different to get them cruncy?

    1. you’ll most likely need to cook them a minute longer. baking cookies for a shorter amount of time and letting them rest on the pan to finish cooking allows the cookie to have a softer texture. I would cook them for 13 minutes and let them finish cooking on the pan outside of the oven. a minute really can change the texture of the end result.

    I used GF flour 1/3 cup turbinado sugar and raisins to make them healthy. They were still plenty sweet because of the sugar in the raisins and the PB. Yummy! Thank you!

  9. These are fantastic. I use organic whole wheat pastry flour for an even healthier cookie treat. Everyone loves them. Just made them for the fourth time. Thanks.

    Delicious cookies! I made them as directed except I eyeballed the peanut butter and cinnamon and added a little extra of each. Also, I prefer my cookies a little bit more one the golden brown side, so 12 mins was right where I wanted to be 🙂 Will definitely be making again!

    I made these this morning and doubled the recipe… they came out perfect I would post a picture but I can’t see a place to do that.

  12. I doubled the recipe, added currants and used a 1 tbsp scoop to drop the cookies. Then i reduced the baking time to 10 minutes. I got 86 cookies, worth 3 WW Smart Points each. The cookies are about 1.5 inches across and makes 4 bites, just right for a low point treat.

    I’m in trouble! I don’t like peanut butter cookies, so I often make them for my husband because they’re a dessert I know I won’t be tempted by. On a whim, I decided to make these instead…and I ate one. Then, I ate another. They’re absolutely delicious, and I feel that the oatmeal lessens the intensity of the peanut butter. One word of warning, do not overcook these cookies. They taste much better soft and chewy, than dry and crumbly (which is how I usually prefer my cookies). Great recipe, thanks!

    Delicious. Followed the recipe- didn’t flatten the centers -andThe cookies were soft and chewy. I made a double batch to start with. The cookies started disappearing so I made another double batch. Yummy!

  16. I have a question more than a review. How many make a serving? One of my sisters is type 1 diabetic and I wanted to plan ahead for when I make this recipe, so I can tell everything she needs to know. The recipe sounds delicious!

  17. 4 stars
    Delicious. But I’m still trying to figure out how to stop them from crumbling. I have added more flour and another egg and it seems to help. Maybe next time I will double the flour and egg and baking soda.

    Cookies cooked up fine. Soft inside and nice gentle crisp on sides. Make sure to leave them on the trays a few minutes. It does help.
    My only issue was the implication that the recipe made 18 cookies. I doubled the recipe and got 68 3” cookies! Oh they’ll all get eaten but the box score has to be a misprint.

    I’ve made this recipe countless times exactly as written. They always come out perfect. They are a family favorite. The best peanut butter oatmeal cookie recipe I have found.

    I have baked these cookies twice and they are so good. They are slightly chewy and the flavors of peanut butter and oatmeal combination are rich and delicious.

    Firstly, I am a complete beginner, I’ve attempted cookies before but they were a disaster. I’m thankful to say that I have made successful tasty cookies for the first time in my entire life!!!! Really thankful for the recipe! My cookies did flatten and did not crumble at all, look like the subway cookies but smaller and a littttle bit thicker, taste even better and have chewy inside, biscuity outside!!!!! Thank you so much for this recipe, really. I misread the ingredients and used 2 eggs instead of 1 large but my eggs were medium sized. Also I only had brown sugar available in the house, so I added little less than 2/3 cup of brown sugar. I also put Hershey’s hugs and kisses in the middle after baking for 8-9 minutes and let them baked for a little more to let the chocolate melt inside. I used the same ingredients, and ended up with 35 medium sized cookies.

    Thank you again!

    I made these with vegan protein powder because I didn’t have any flour or reasonable substitute and they turned out amazing. I plan on using this recipe again and again. Thank you so much for sharing.

    Okay, so I’m highly confused by how anyone can mess this up. I’ve made them multiple times now, per my husband who is obsessed with them. I even put the butter in the microwave to soften. I do put them in the fridge for an hour or so to chill, but I don’t even have to do that. I just use a cookie scoop and put them on a greased pan. They don’t spread out which is nice and are so yummy. I’m going to throw some chocolate chips in some for me. Great recipe!
