Flourless Peanut Butter Walnut Brownie Cookies

Flourless peanut butter walnut brownie cookies are the perfect combination of chocolate, peanut butter, and crunchy walnuts.  It’s all tucked into a gluten free, fudgy, brownie cookie. I made them especially for you, and to celebrate National Grab Some Nuts Day!

I can’t remember the last time I had a down and dirty, sugar laden, loaded with fat brownie. *moan*

Treats like caramel bacon brownies, my best ever brownies, and mint cheesecake swirl brownies used to make regular appearances on my hips dessert plate. Then I started my quest to lose 50 pounds by my 50th birthday. When that failed, my #FitAt50 plan kicked into gear. I’m sure it was at least a year ago that I sank my teeth into a fudgy, chewy brownie that made my eyes roll into the back of my head, and I miss them. A lot.

Or rather, I did miss them a lot, but then I created these flourless peanut butter brownie cookies. After that, my craving for a chewy, chocolaty brownie was quenched.

I adapted the recipe from this one that I found on Sally’s Baking Addiction.  Sally’s version doesn’t include nuts, but it would be downright nutty of me not to include nuts. After all, this is a grab some nuts day recipe, right?  Right!  So, I added walnuts. And I used a sugar substitute instead of refined, granulated sugar. If I’m making a sweet treat that doesn’t require wearing stretchy pants afterward, I need to reduce the calories and fat a bit.

A note about these nutty, flourless peanut butter brownie cookies:

The peanut butter I used in them is lower in sugar and fat than most, but that doesn’t mean you can eat twice as many. It’s real peanut butter and it does have sugar in it. These cookies are not calorie free by any stretch, my friend. They’re just a lightened up version of their former self.

Speaking of lightened up, that’s what I hope to become after I’ve finished the group exercise challenge at the gym in town.  I want to be the same me, but in a lighter, more flexible, healthier body.

I started taking Zumba classes 3 days a week instead of the core training that I had been doing. Oddly, it seems to be easier on my bad joints, and it’s crazy fun, I tell ya!

When I wear my yoga pants, I look like a whale with sausage casings over my legs, but it’s okay. When Dear Future Husband comes on, I have fun and dance like nobody’s watching me! I’m burning calories with a small group of four to eight women rather than fifty of them.  It’s much less embarrassing that way.

Okay, let’s have some flourless peanut butter brownie cookies!

Flourless Peanut Butter Walnut Brownie Cookies

Prep Time 5 min Cook Time 10 min Serves 12

These thick, fudgy flourless peanut butter walnut brownie cookies are made in less than 15 minutes! Chewy, melt-in-your-mouth good, and gluten free, too (check ingredient labels for gluten!)


  • 1 large egg
  • 1 cup (250g) peanut butter, at room temperature (I used Simply Jif)
  • 1 teaspoon honey
  • 1/3 cup (67g) Erythritol, Rapadura, or brown sugar, lightly packed
  • 1 teaspoon baking soda
  • 3 Tablespoons unsweetened cocoa powder (Dutch-process may be used)
  • 1/2 teaspoon vanilla bean paste or vanilla extract
  • 3/4 cup chopped walnuts


  1. Preheat oven to 350 degrees Farenheit and line two large baking sheets with parchment paper or silicone baking mats.
  2. In a medium bowl, beat the egg. Add the peanut butter, sugar, baking soda, cocoa powder, and vanilla. Mix everything together very well, then fold in the walnuts until combined.
  3. Scoop the dough, about 1 ounce (2 Tablespoons) each, onto prepared baking sheet. Place 6-7 cookies onto each baking sheet, leaving space for spreading. Gently press down on the dough mounds with the back of a spoon to slightly flatten.
  4. Bake for 8 to 10 minutes for chewy, brownie-like cookies and up to 12 minutes for crispy cookies. Allow the cookies to cool for 10 minutes on the baking sheet before transferring to a wire rack to cool completely.
  5. Cookies stay fresh when well-covered at room temperature for up to 7 days, and freeze well, up to 3 months.

    Whenever brownies and cookies are in the same place, I can never decide which I want. With this recipe, I don’t have to!

      Indecision is the worst, isn’t it, Erin? I’m so glad that these cookies take the pressure off for you 😉

    I am totally in love with these cookies. Anything with the word brownie in it is going to catch my eye. Add nuts and it’s even better. Must try. Immediately.

    Love the photo of you working out. Kudos man, it’s not hard getting in shape at our age. Right there with you. I’m doing mini-me’s boot camp soon. So scared.

    Thanks so much for joining us for the event. And for all the help. Thank goodness for nutty friends. xx

      Thanks, for having me, girlyfriend. Oh, and I can’t even tell you how badly I’m regretting the decision to post that photo. I feel like I’m gonna give all of my readers nightmares. Ha!
      The thing is, I think seeing myself on the “big screen” is giving me some accountability to follow through until the end this time. Besides, it’s freaking inspiration to sweat my a$$ off when I see those thunder thighs of mine 😉
      I hope K doesn’t beat you up too badly, but I’m proud of you for going for the challenge. Yay us!

    Oh Becca, you are talking my language with these cookies! Chocolate, peanut butter AND flourless. Only thing better would be making an ice cream sandwich out of them. Oh wait, oops, supposed to be healthier. Umm, frozen yogurt!
