The peanut butter cookies are flourless. That’s right, no flour is needed. They are gluten-free and SO easy to make. Once the cookies are baked and cooled, the real fun begins.

I take a cookie and spread silky chocolate ganache on the bottom. Next, I add a layer of creamy, dreamy peanut butter frosting. Put another peanut butter cookie on top, slightly press together, and VOILA…cookie heaven!

For the Cookies:

For the Chocolate Ganache:

For the Peanut Butter Filling:


  • Preheat the oven to 350 degrees. Line a large baking sheet with a Silpat baking mat. Set aside.
  • In the bowl of a stand mixer, mix the peanut butter and sugars together until creamy and smooth, about 2-3 minutes. Add the egg, vanilla, and mix until combined. Add the baking soda and salt and mix until combined.
  • Spoon dough into balls, about 1 tablespoon of dough for each cookie. Place them on the prepared baking sheets, about 2 inches apart. Smash dough balls with a fork, creating a criss cross. Bake for 8-10 minutes. Don't overbake. Remove cookies from oven and let them sit on the baking sheet for 2 minutes. Move to a wire rack and cool completely.
  • While the cookies are cooling, make the chocolate ganache. Place the chocolate chips in a medium bowl. Heat the cream in the microwave, in an microwave safe bowl, for 30-60 seconds, or until cream is hot, but not bubbling. Pour hot cream over chocolate chips and let sit for 1 minute. Stir until the chocolate melts and you have a smooth and silky ganache. Set aside.
  • Next, make the peanut butter frosting. In the bowl of a stand mixer, beat the butter and peanut butter together until smooth. Slowly add in the powdered sugar. Mix until smooth. Add the milk and vanilla and mix until the frosting is creamy and smooth. If you need to add a little more powdered sugar or milk to reach your desired consistency, you can. You want the frosting to be thick.
  • To assemble the sandwich cookies, take one cookie and spread ganache on the inside of the cookie, about 1 ½ teaspoons. Next, either spread on the peanut butter frosting with a spoon or put the frosting in a pastry bag and pipe the frosting onto the ganache. I like to pipe the frosting. I use about 1 tablespoon of frosting. Top with another cookie and gently squeeze so the ganache and frosting meet the edge of the cookies. Continue until all of your cookies are sandwiched!
  • Note-these cookies will keep in an airtight container on the counter for 2-3 days.

  1. I’ve got my glass of cold milk, now I NEED these cookies!! They look so good I might need more than just one glass of milk 😉 love love love

  2. I agree – National Peanut Butter Day is the best! And these cookies look like a perfect way to celebrate! For the ganache, would using almond or coconut milk work instead of the heavy cream? 

    1. 5 stars
      Such a good recipe and so easy. The ganache is great but I usually just do the cookie and peanut butter filling. Thank you for the great gluten free cookie!

  3. Does it matter if you use natural peanut butter or the creamy peanut butter that has been emulsified?

  4. So many of my favorite words together: flourless, peanut butter, chocolate, ganache, cookies? Total yum!! These just look divine!

  5. If i wanted to make some of these ahead of time and freeze – do you think it’d work? Or freeze pieces separately?

    1. I would probably make and freeze the cookies and then make the ganache and frosting the day I want to serve them!

  6. Maria! I think I’m going to have to celebrate Peanut Butter Lovers Day a little bit late! But I think Peanut Butter will understand, he’s like that 😉
    Seriously, these cookies look amazing! And as someone who has to stick to a GF diet, I love that they are already gluten free and I can just make, bake, and eat! Can’t wait to make these and share them with the other PB lovers at work 🙂

  7. Did you use natural peanut butter or “regular” peanut butter for your recipe? I see you said you could use either….but when I use natural, the only kind I buy, the cookies tend to be crumbly 🙁 My GF daughter who is no longer DF will LOVE these!!! Thank you!

    1. I tried them today with the natural peanut butter and the same crumbly thing happened! 🙁 

    1. It is a silicone baking mat. If you don’t have one, you can still make the cookies. Use parchment paper!

  8. Please be aware, not all powered sugar is GF. Check the lable to make sure it does not contain wheat starch.

  9. I just threw together a batch of these and they are EVERYTHING!!!!! Peanut butter cookies were born for this. THANK YOU!!! P.S. my wife is allergic to egg yolks, so I subbed two egg whites + 1T ground flax seed. It’s fantastic!

  10. Cookies were very flat and crisp even after playing with the time and temperature. I get the no flour and gluten aspect, but cookies without even a touch of flour are flat as a tire. Such a waste of ingredients and peanut butter is my favorite food. 🙁

  11. I’m making these for a baby shower and did a test run. The cookies spread to what appears to be twice the size of yours from the pictures. I want to go for the smaller cookie, like yours. Do you think chilling the dough would help this? Thanks for the great recipe — they tasted amazing!

  12. I made these tonight. They were so good that I had to make another batch. Delicious!! I do think that a double batch of cookies and a single batch of ganache and filling would work well. My cookies were not flat at all and I did not refrigerate them. Thanks for your terrific recipes!

  13. These look phenomenal! Can’t wait to make them with the kiddos as a Happy Mother’s Day to me treat!

  14. Hi Maria,
    I made your recipe and the cookies taste so yummy but they crumble to pieces. Can you suggest what I may  do next time? 

  15. These are the BEST peanut butter cookies EVER! Everyone who eats them- loves them. Not only are they gluten free but I tweekwd them with Earth Balance butter for the filling and almond milk to make the ganache- making them lactose and gluten free- but most of all DELICIOUS!

  16. I made these for a friend and she loved them! My official taste tester (my husband) also approved of them. I personally don’t eat peanut butter in desserts, but I strongly considered it with these cookies. Thanks for the recipe!

  17. Just made these cookies. They turned out beautifully, even with the substitute of 2% milk for the cream in the ganache (all I had). My two kids and I all declared them the very best cookies we’ve ever had:). Thanks for a great recipe! 

  18. I have made these in the past for a family member who suffers from celiac disease and they were great! He tolerated them just fine. I will be making them again this weekend.

    I make these often as my daughter is gf..  I make them for bake sales so people have a choice. I have been told to quit my day job and bake these full time!! They are so delicious! And surprisingly easy to make 

  20. 4 stars
    I just made these as I love finding a good thick chewy PB cookie recipe. They are amazingly delicious as I expected. My question is that my cookies seemed to spread more than yours and are thinner with less definition in the fork markings. I would prefer thicker and more definition and wondered if you had any suggestions? Not sure how flat you actually made them when you put the imprints in with the forks? Not sure if that makes a difference? Just wondering if you had any ideas or had any similar issues when testing these. Thanks so much!

  21. These look INCREDIBLE! Super excited to make them! I saw your comment about leaving them on the counter for 2-3 days. If I was to keep them in the fridge after a few days, do you think they’d last through the week?

  22. 5 stars
    This was a great recipe!! No changes made and it was perfect. Cookies by themselves are great if you just want the cookie.

  23. 5 stars
    Crazy good – so yummy & easy to make too!
    Caution: I used a large scoop which made seven complete sets. Way too big for portion control but wow, what an amazing cookie – definitely a keeper in my cookie stash. Thank you.

  24. I just made these cookies and they came out perfect. The cookies would be great in their own but the ganache and peanut butter filling make them really special. This recipe is a keeper!

  25. 5 stars
    These cookies are amazing! We call them “One Night Stands,” because they’re so decadent and delicious. Also you can only eat one at a time, because they’re so rich! I love that I can share them with gluten-intolerant friends. Thank you so much for this recipe!

    Yesterday we celebrated July birthdays in the art studio, I am gluten-free the only one in the studio, however one of the ladies said she was going to make a cake one that even I could eat (although I was very hesitant, because people always say that, but it, indeed turns out to have some type of gluten in it).

    Anyway, the young lady making the cake an ounce after everyone had a slice eating, saying how delicious it was looked at me and said I made this with you especially in mine. You can have a piece.

    She announced she made a flourless gluten-free cake with me and mind and so I had a piece it was the most decadent piece of gluten-free (first time ever flourless cake) I’ve tried everyone in the studio was raving about it.

    Thank you for sharing this recipe.
