They’re perfect if you don’t have a ton of ingredients on hand, and they take very little preparation at all to make.

We love serving these around the holidays but they’re also delicious to be served year-round!

The Secret to Flourless Cookies

So, if you’re wondering how can cookies work without using any flour? It’s quite simple – lots of peanut butter. 😉

It helps give the cookies shape, structure, and chewy texture without needing any flour at all! One cup is used per batch, so if you aren’t a huge peanut butter fan, then these cookies might not be for you. But you might be surprised once you try one! They are that delish.

Ingredients – What You Need

Below you’ll find the full list of ingredients needed to make these cookies!

Ingredients for flourless peanut butter cookies arranged on a wooden board.

  • Peanut butter: use creamy peanut butter or almond butter!
  • Coconut sugar: This sugar is my favorite healthier swap for brown sugar. You can swap it one to one for brown if desired! 
  • Vanilla extract: to add the perfect flavor! 
  • Egg: to bind the ingredients.  
  • Chocolate: use dark chocolate for dairy-free or semi-sweet if preferred. 

How to Make Flourless Peanut Butter Cookies – Step by Step

(1) First, add all of the ingredients (minus the chocolate) into a mixing bowl.

(2) Mix with a rubber spatula until the dough forms and the ingredients are combined.

(3) Form the dough into 2-inch dough balls (use your hands to roll them). Then use a fork to press down on the cookie and make a cross pattern.

(4) Then bake the cookies for 8 minutes at 350F. Let cool, then dip or drizzle with melted chocolate!

Tips for Success

Avoid using “stiff” or dry peanut butter! This recipe really relies on peanut butter to support a chewy and soft texture. It’s important that the peanut butter is creamy and smooth (think spreadable!), if it’s stiff and dry it will not work for the recipe.

My favorite sugar to use for these cookies – I recommend coconut sugar as a healthier alternative to processed sugar. But you can also use brown sugar instead – I do not recommend white sugar as a substitute for this specific recipe. White sugar does not have molasses in it (like brown sugar does) so it will not add the moisture that’s needed for soft and chewy cookies. I have not tested this recipe with maple syrup or honey.

Add some spices! If you’d like to switch up the flavor, you can add 1/4 teaspoon of either cinnamon, pumpkin pie spice, ginger, or some nutmeg.

Change up the chocolate – I personally love using dark chocolate for these cookies because it pairs so well with the peanut butter! But you can also try milk chocolate, semi-sweet, or even white chocolate! Or a combination. Mix it up and let me know what flavor you like best in the comments!

How to store cookies: place cooled cookies in an airtight container or ziplock bag and store them in the refrigerator for up to 5-7 days. 

Frequently Asked Questions

Can I use crunchy peanut butter? I personally have never tested it, but if it’s easy to spread and not dry, it should work fine. If you do try it with crunchy peanut butter, let me know in the comments how they turned out!

Can I freeze these cookies? Yes! They freeze great. Store the baked cookies in a freezer-friendly bag and freeze them for up to 1 month! You can also freeze the dough balls for up to 1-2 months, then remove them and bake them according to instructions when you want cookies right away.

Can I make them vegan? You can! Swap 3 Tablespoons of pumpkin puree (not pumpkin pie puree) for 1 egg. I’ve not tested this recipe with a flax egg, but it should work!

Instructions

  • Preheat oven to 350F.
  • Mix the ingredients: In a large mixing bowl, use a rubber spatula or large spoon to mix together the peanut butter, sugar, vanilla, and egg.
  • Roll the dough: Use a cookie scoop or eyeball to measure the dough and use your hands to roll them into 2-inch dough balls. Arrange the dough balls onto a sheet pan lined with parchment paper.
  • Press with a fork: Then use the back of a fork to press a criss-cross design onto each dough ball. This should flatten the cookies quite a bit.
  • Bake: then bake the cookies for 8 minutes.
  • Melt dark chocolate: either in a double-boiler or in a microwave – melt the dark chocolate. If using a microwave, do 30 seconds at a time (stirring in between each 30 seconds) to prevent the chocolate from burning.
  • Decorate: Then drizzle melted chocolate over the baked cookies! Let cool and allow the chocolate to solidify before enjoying! You can also pop the cookies in the fridge to speed this process up. Enjoy!
