Do you ever get the craving for some cookies but look in your pantry and you don’t have most of the ingredients needed? That was me today. I had the biggest hankering for something sweet but didn’t really want to venture out to the store.

I’m talking, no butter, no gluten-free flour, no baking soda, no vanilla extract kind of day. Wow, do I need to get to that store. But first, in grocery desperation beautiful things are born.

Like these 3-ingredient flourless peanut butter cookies. The good thing is we ALWAYS have peanut butter in our house!

We’re kind of peanut butter lovers in this house. The dog, too. We don’t give her peanut butter too often, but once in awhile as a treat. And yes, we have made sure there is no xylitol in the peanut butter we purchase. Which… doggie parent PSA: if you give your dog peanut butter make sure that xylitol is not the sweetener in there.. it is super harmful to dogs! Okay, okay. Back to these 3-ingredient flourless peanut butter cookies.

A quick chill in the refrigerator makes sure these cookies set up really nicely without spreading too much. Criss cross with a fork and bake! Dessert does not get much easier than this.

The first time I tried this recipe out of sweet tooth desperation I didn’t think it was going to work, but I was so pleasantly surprised. Now these flourless peanut butter cookies are a staple in our house!

They’re naturally gluten-free, too which is great for me since I have celiac disease. But, my boyfriend loves them too! Though… I don’t think he’s ever turned down a gluten-free cookie I’ve ever given him.

One bite of these flourless peanut butter cookies and you’ll be hooked. You won’t believe they were made with just THREE ingredients. They’re crisp on the edges, chewy in the center and full of peanut buttery goodness.

Tips and Tricks for Making 3-Ingredient Flourless Peanut Butter Cookies

  • I used a creamy peanut butter, rather than the natural kind. That’s just typically what we have on hand in our house. If you use a natural peanut butter, you may want to chill the cookie dough for a longer period of time so that they don’t spread like crazy in the oven. I haven’t tested it this way, however.
  • Bake these cookies for 10-12 minutes at 350F until the edges are set and the cookie no longer looks glossy. You’ll want to make sure to let them cool completely before picking up otherwise they’ll fall apart.
  • This recipe makes 8 large cookies, if you’d like to make smaller cookies you definitely can, just reduce the baking time accordingly.
  • If you don’t have brown sugar on hand, you can use the same amount of granulated sugar in this recipe. I just think brown sugar gives these cookies a deeper molasses-like flavor which I love.
  • If you don’t want your fork to stick to the dough which you make the cross-hatch pattern, dip the fork in sugar first!

  1. These sound delicious! I’m always looking for quick and easy cookie recipes to try. Can’t wait to try them!

    1. Thanks Lauren! They’re my favorite for when I’m looking for something sweet and fast!

  2. Peggy, will this recipe work with sunflower seed butter or soy butter?

    1. I’ve never used soy butter before, so I can’t say for sure on that one. But it does work with sunflower seed butter! Enjoy!

    I’ve made it with regular sugar and added chocolate chips. I used all natural chunky peanut butter because it was all I had. I baked them (not prechilled) on a stone. Halfway thru baking time I flattened. Delicious. just don’t overbake. My friend Liz gave me her recipe. Surprisingly satisfying.
