Peanut Butter Oatmeal Sandwich Cookies

I’m normally super organized about making the weekly menu, writing out the shopping list, and then doing a quick inventory check before we go shopping to make sure I don’t buy items we already have.  Apparently though, my eyes are blind to oatmeal when I do my inventory check.  We end up buying it only to come home and find we already have three (or more!) containers in the pantry.  So, I put myself on an oatmeal-buying ban and am making an effort to use up all these dang oats.  That was the main inspiration behind trying these cookies, but wow, am I glad I tried them!

The cookies are perfectly chewy peanut butter cookies with a lovely golden brown color, and the filling is a simple peanut butter frosting.  The oatmeal primarily provides the chewy texture of the cookie but the actual oatmeal flavor isn’t really noticeable.  As with a lot of sandwich cookies, I think the filling helps keep the cookies soft and tender.  Apparently these are similar to the Girl Scout DoSiDo cookie or to Nutter Butters, but due to my childhood dislike for peanut butter, I never ate enough of either to know whether this is an accurate comparison.  Either way, we love these cookies.  Andrew enjoyed one during his Easter egg hunt and I think he cared more about the cookie than the eggs 🙂

Peanut Butter Oatmeal Sandwich Cookies
Printer-Friendly Version

Yield: about 18 sandwich cookies
For the cookies:
¾ cup all-purpose flour
½ tsp. baking soda
¼ tsp. baking powder
½ tsp. salt
8 tbsp. unsalted butter, at room temperature
½ cup creamy peanut butter
½ cup granulated sugar
½ cup light brown sugar, packed
1 large egg
1 tsp. vanilla extract
1 cup quick-cooking oats

For the filling:
3 tbsp. unsalted butter, at room temperature
½ cup creamy peanut butter
1 cup confectioners’ sugar, sifted
3 tbsp. heavy cream

To make the cookies, preheat the oven to 350˚ F.  Line a baking sheet with parchment paper or a silicone baking mat.  In a small bowl, combine the flour, baking soda, baking powder, and salt.  Stir together with a fork to blend.  In the bowl of an electric mixer fitted with the paddle attachment, cream together the butter, peanut butter and sugars on medium-high speed until light and fluffy, about 2-3 minutes.  Blend in the egg and vanilla extract.  Add the dry ingredients and mix on low speed just until incorporated.  Stir in the oats until evenly blended.

Use a small cookie dough scoop to portion out the dough (about 2 teaspoons), rolling each portion into a ball, and place them on the prepared cookie sheet, a couple inches apart.  Bake about 10 minutes, rotating the sheet halfway through baking.  The cookies will be light golden brown and slightly puffed.  Let cool on the baking sheet 5 minutes, then transfer to a wire rack to cook completely.  Repeat with the remaining dough.

Once the cookies have cooled completely, pair them up by size.  To make the filling, combine the butter, peanut butter, confectioners’ sugar in the bowl of an electric mixer.  Cream together until well combined.  Mix in the heavy cream until smooth and fluffy.  Use a pastry bag fitted with a plain round tip to pipe a swirl of filling onto the flat side of one cookie of each pair.  Sandwich together with the remaining cookie and press down so that the filling reaches the edges.  (Note: This filling recipe makes *just* exactly enough to fill the cookies.  If you like a large amount of filling or just want to be sure you have enough,  you might consider increasing the amount of filling by 50%.)

  1. These look just like the Girl Scout cookies, though am sure they taste worlds better. What a neat idea! 🙂 I’d love to try them.

  2. Those look great! And I have to say, that picture of Andrew is super cute! He looks like such a big boy in his little jeans!

  3. My boys will be ready to run away with you when I make these for them. They look great, Annie!

  4. Oatmeal and peanut butter are two of my favorite foods, so I’m sure I’d LOVE these cookies.

    Adorable photo of Andrew! I’d have a huge grin on my face also if I had a handful of those cookies ;).

  5. These look so good and how cute is Andrew with his cookie and egg?! I don’t know how you manage to handle residency, a baby, AND this blog. I’m a third-year in medical school with no baby and I struggle to find the time (except when I’m on elective which is right now hence the comment). I’m so impressed by your obvious time management skills!

  6. I just love these. They look and sound amazingly good. and Andrew is such a little cutie 🙂

  7. I get so excited when I see an oatmeal cookie recipe that isn’t Oatmeal Raisin… THANK YOU!! These look amazing too and I think my husband will love them.

  8. Peanut butter and oatmeal are a combination I’ve never tried before but sounds fabulous.

    And I understand about “blindness” in your pantry. I have about 5 cans of hominy in there right now. Guess I want to make sure I have it for my favorite rice recipe.

  9. Those look “AWESOME” to quote my kids who are looking over my shoulder. I also love the ability to multi-task, looking for eggs with his cookie. That’s a smart kid 🙂

  10. How adorable is Andrew? I love, love, love seeing little boys in “man” clothes, rather than something with, say, an applique of a teddy bear on it. When my older son was little, my absolutely favorite shirt of his was a red and black buffalo-check flannel. I called it his lumberjack shirt. Oh, yeah. And the cookies look delish, too.

  11. drool! Annie, if you haven’t tried Dorie’s Chunky PB and Oatmeal Chocolate Chipsters, you must do so soon…after all, you can’t let all those oats go to waste! 😉

  12. these sound fabulous!

  13. i’m not that big on peanut butter, but i know hubby would die over these. oatmeal and PB sandwich cookies? heaven sent. 🙂 i’ll have to give these a try!

  14. i haven’t made these in ages. i just love that first photo!

  15. That’s so funny – you’re on an oats ban, while we’re on a peanut butter ban due to an overbuying situation created by my husband 🙂 Either way it puts both of us in a good situation to bake these lovely cookies.

  16. These look insanely delicious! I want some!

  17. A fabulous treat!

  18. omg those were my favorite type of girlscout cookies growing up. I bookmarked this one to make for sure! Yum!

  19. Awww, what a cute pic of Andrew! These remind me of the Girl Scout DoSiDos – yum!

  20. Oooh I love both peanut butter and oatmeal so I definitely have to make these soon!

    By the way, Andrew is so adorable!

  21. What a cutie pie!! These look delicious!!

  22. These are amazing! I would say they are similar to DoSiDos or Nutter Butters in flavor, but they’re chewy instead of crunchy (which is a good thing in my book). I had all of the ingredients in my pantry so I had to try them right away. I made them in just over thirty minutes from start to finish. I can’t wait for my family and friends to try them tonight (if there are any left).

  23. Oh, I love that there is peanut butter in the cookie too. Yum! I love oatmeal cookies and I love peanut butter. Must make these!

  24. How yummy – I’ve never heard of the girl scout cookie but these look yummy. I love using oats in baking.

  25. I have a slight oatmeal obsession so these cookies are right up my alley! Funny about your oat ban. I tend to do that with carrots for some reason…at least oats last a long time!

  26. I love the do-si-dos. But these look so much better than the girl scout cookies I had as a kid. Great job, I can’t wait to try these myself.

  27. They look so yummy ! When isn’t peanut and oatmeal combined good ?!

  28. I don’t blame him…I would have been more into the cookies, too!

  29. I made these this afternoon for my husband’s work meeting and the three attendees demolished the entire batch 🙂 Great cookies!!!

  30. Awww, such a gorgeous picture of the baby!! No better advertisement for this recipe, either. The cookies look delicious. 🙂


  31. I think I need to ban myself from your blog! I’m trying to be a bit healthier and instead I come and drool at all the photos on here!

    I would be making these in an instant, but my boyfriend is allergic to nuts! Argh! Oh well, they’re in my recipe box now to make as soon as I can!

  32. These are great. Made them last night. They do remind me of Nutter Butters only softer and creamier! So tasty! Keep the great recipes coming.

  33. I made these last night. They’re fantastic!!

  34. You have made me a hero with my family. These cookies were amazing. They took to dairy-free living with ease. Thank so much!!!

  35. Those look awesome! I love oatmeal cookies. Adding peanut butter just makes them better 🙂


    they look awesome!

  37. I love sandwich cookies! And that is such a cute pic of Andrew.

  38. I made these last week for a potluck and they were a big hit — *but* I have to admit, I enjoyed eating the leftover icing on its own much better than the cookies. Seriously. Next time I’m skipping the cookies and just taking a spoon to the icing…mmm…

  39. Annie thank you so much for a wonderful, easy and scrumptious recipe. I’ve been drooling over these since you posted them. I was finally able to make them tonight and my kids and husband (who doesn’t like sweets) loved them!! Thank you so much.

  40. Just made these cookies because my husband was begging for dessert 🙂 I made your Shrimp, Feta, & Herb Mac & Cheese for dinner and it was delicious! I told my husband that you had a good recipe for peanut butter oatmeal cookies on your blog and he insisted that we try them out! So far, your recipes have been no-fail!! Thanks so much! Btw, the cookies are INCREDIBLE!!

  41. Wow these look so delicious and way too tempting. You have so many yummy looking baked goods! I think my daughter will like these.

  42. These cookies were AMAZING. I made them for the 3rd time this weekend and they were a hit. Everyone loved the soft chewy texture. Thanks again for ANOTHER great recipe.

  43. Hiya. New to your blog, love it! This recipe looks amazing! Do you think it would work if I subbed almond butter for the peanut butter? Obviously, the taste would be different, but I just wonder how different (or similar) almond butter is to peanut butter in terms of texture, consistency. Hmm. Might have to try it to find out!

  44. These are AMAZING! I just made them, partly because Do-Si-Do’s are my mom’s favorite Girl Scout cookie, and partly because I wanted something good to bring to my grandparent’s tomorrow, and I am so so so happy I chose these. My mom said they are the BEST cookies she’s ever had- way better than the Girl Scout cookies. I will be making these again and again. Thank you!

  45. OMG! These are amazing. I doubled the recipe for the cookies, so because of the warning I tripled the frosting recipe and have a bunch left – not sure if I didn’t put enough in the cookies, but they still turned out DELISH! I always worry when making a new cookie recipe that they won’t be soft enough – but these turned out PERFECT! Thank you so much for sharing this one!

  46. These look really yummy! My boyfriend has developed a peanut allergy as an adult, so I will have to replace the peanut butter with homemade almond butter (so I don’t kill Him lol) I look forward to seeing how tasty they come out with the substitution ^_^
