Flourless Triple Peanut Butter Cookies


Flourless Triple Peanut Butter Cookies

Fireflies are another perk of summer.  As if fresh fruit and vegetables, longer days, sunshine, warmth, and flowers weren’t enough, there are those majestical little bugs literally lighting up the night sky.  I love seeing them fly around.  Even when I’m having a less than stellar day, one flash from a firefly and I can’t help but smile 🙂

When I was younger, I would sometimes go outside and catch them.  I was pretty terrified of bugs (who am I kidding – I still am!), so clasping my hands around one was accompanied by lots of shrieking and wincing, as though this harmless little bug could actually do any damage to me.  No jars were involved, no bugs harmed in the midst of my summer fun.  I wouldn’t have been able to live with myself.

The days of catching fireflies are long gone in my world, though it would probably do me some good to cut loose and head outside to recreate part of my childhood.  Regardless, I am no less fascinated by fireflies today than I was then.  This year there seem to be more than ever before.  Just a moment or two of looking out the window reveals at least a dozen of them making their presence known.  Some even come right up to the window to say hi!  I become a total dork and say hi right back, hoping they’ll flash again.  I love fireflies – they are truly amazing!

These Flourless Triple Peanut Butter Cookies are also pretty amazing.  Taking flourless peanut butter cookies to a whole new level, these are full of peanut butter chips and Reese’s Pieces – two of my favorite things.  Dangerously easy to make, I can’t tell you how much I love these cookies hot out of the oven.  I crave them constantly.  Give them a try and you’ll crave them all the time too!

Flourless Triple Peanut Butter Cookies

Flourless Triple Peanut Butter Cookies

Prep Time: 5 minutes

Cook Time: 15 minutes

Total Time: 20 minutes

Yield: 8 cookies


1 cup creamy peanut butter

1 cup packed light brown sugar

1 large egg

1 teaspoon baking soda

1 teaspoon pure vanilla extract

½ cup peanut butter chips

½ cup Reese’s Pieces


Preheat oven to 350 degrees F. Line a cookie sheet with parchment.

In a large bowl, stir together peanut butter, sugar, egg, baking soda, and vanilla until well combined. Add the chips and Reese’s Pieces and mix until incorporated.

Using a regular sized ice cream scoop, scoop the dough onto the prepared sheet pan. Cookies do not have to be spaced too far apart, as they will not spread much. Flatten cookies slightly with your hand, as they will not flatten much during baking.

Bake for about 15 minutes, until cookies have cracked and are almost set. Eat warm out of the oven or store in an airtight container at room temperature for up to 5 days. Cookies may also be frozen, wrapped in parchment and foil and placed in a zipper bag for up to 3 months. Thaw at room temperature for a couple hours.

  10. You had me at TRIPLE peanut butter!! Mmmm – I adore a rich, peanut buttery cookie!

  11. Dad says:

    These are outstanding!

  12. Deb says:

    Having a bit of firefly envy! I have never seen any here along the central coast of California. I imagine the summers are too foggy and cool? But I have had peanut butter cookies and often find them dry and without much peanut flavor. You flourless version magnificently cures those complaints, an irresistible cookie!

  13. Natalie says:

    PB mania, love these already and I haven’t even tried them lol

  14. Gahhh – are you serious??! I need these. I have all of the ingredients too, well besides the Reese’s but that could be easily solved!

    • Laura says:

      Or if you don’t want to buy the Reese’s, just double up on the pb chips – I’ve made them that way too and they are just as delicious!

  15. I love making these cookies. They were one of my kids stand bys growing up. and I love fireflies, but unfortunately Colorado does not have them Though my kids are now just about 23 I remember when they were 10 and we took them to Illinois. Up to that point they had only heard us describe fireflies. They were so excited to actually see them.

  16. I’m terrified of bugs so even though fireflies are pretty, I’m not brave enough to try to catch them! I seriously need these cookies in my life. I keep collecting flourless PB cookie recipes and I’ve yet to make any of them. I’m printing this out and I swear, I’m going to make these, lol.

    • Laura says:

      You have to try these, Nancy! You’ll love them and they are sooooo easy to make. You’ll wonder why you waited so long.

  17. Triple peanut butter? I’m in! Gotta make some of these – and eat them while watching the fire flies. We’ve been noticing more this year than in the last few years, although not nearly as many as when I was a kid. Of course I was a kid then, and you know how kids see the world. 😉

  18. Joanne says:

    I’ve recently developed a serious fear of fireflies though I loved them as a kid. It’s really weird!

    Peanut butter is the eternal love of my life though. These are speaking to my soul.

  19. mookies says:

    Perfect for the lovers of peanut butter!

  20. Tammela says:

    Wow, these look amazing. There can never be too much peanut butter.

  21. These cookies look like perfect afternoon snack territory. Or perfect crumble through ice cream territory. Either way, yum.

  22. Tara says:

    Mmmm Mmmm good!! I love peanut butter cookies, haven’t tried them without flour before, they look great!!

  23. Heather Beckler says:

    Ainsley is making these cookies right now! Aunt Debbie made these a few weeks ago when we visited; however, Alan and Ashley’s dogs ate them off the counter before we got to eat one:) So we are making our own batch now! Aunt Debbie raves about these cookies. We have never made flourless cookies and are super excited about your recipe! Thanks for the recipe and post!

    • Laura says:

      I’m sure your cookies will turn out just as good as Debbie’s! I hope you all enjoy them. Thanks for trying the recipe, Heather 🙂
