Flourless Peanut Butter Cookies Recipe from

Peanut butter cookies are one of those classic cookie recipes that I just never get tired of making – or eating! My regular peanut butter cookie recipe is full of peanut butter while being rich and buttery. They are a bite of heaven in my book! But, with a nephew who can’t have grain or dairy in his diet and hasn’t been able to since he was born, I’m often fiddling with recipes to try and make something that I think would work for him, as well as for anyone who isn’t able to have grain and dairy in their diets or is just living a grain-free, dairy-free lifestyle.

That’s where these flourless peanut butter cookies come into play.

Full of delicious peanut butter without any grain or dairy to be found in them. But you know what? You don’t miss either of those things in these cookies! Even if you aren’t in need of leaving out the grain or dairy in your diet, you will love them! 

I recommend using smooth peanut butter and not a natural peanut butter in these cookies as the natural peanut butter tends to make these cookies a bit too dry for my preference. And let’s be real, who likes dry, crumbly cookies? Not me! I’m all about a soft, tender cookie instead!

This cookie dough comes together easily without the use of a mixer – just a bowl and a spoon are all that is needed to mix these ingredients together and in less than 20 minutes, you have these delicious peanut butter cookies ready to feed that craving!

Here’s my Flourless Peanut Butter Cookies recipe. I think you’ll love them!

    I’m 71 and I’ve made flourless pnut butter cookies for years BUT they are even more simple….1 cup pnut butter, 1 cup sugar, 1 egg…..mix and roll into balls, put on baking sheet, criss cross with fork dipped in sugar (may try sea salt), bake 10 min or so at 350….don’t let them get too brown. Let sit. on pan as they cool or they will fall apart. I’ve used Splenda too in place of or as half of sugar as I’m a new diabetic. M.A.

    I have found that using natural peanut butter does not make the cookies at all dry if you use no stir all-natural peanut butter or even honey roasted no stir all-natural peanut butter. But I love the recipe. Thank You!!! ^.^

    My family can eat flour and has no allergies but this recipe seemed easy and sounded good. I made them tonight and the recipe did not disappoint. They are very good and I love the texture. Will make them again.

  9. I made these today and they were a hit! I only buy chunky peanut butter. No problem. The chunky was actually nice with a peanut bite within the cookie. Thank you for an easy as well as yummy recipe!

    1. Nadine, I’ll have to try these with chunky peanut butter sometime. So glad you liked them.
