No-Flour Peanut Butter Cookies
You can never have too many peanut butter cookie recipes, and these flourless cookies are some of the best!
One bowl, no mixer, and just four main ingredients: peanut butter, sugar, egg, and vanilla.
What sets this recipe apart from many other peanut butter cookie recipes is that there’s no flour and no butter, making them naturally gluten-free and dairy-free. Since there’s no butter and no flour what you’re left with is a cookie that’s full of bold, robust peanut butter flavor.
These simple peanut butter cookies have a lovely chewiness around the edges and are perfectly soft and tender in the middle. Don’t be tempted to overbake them, because they won’t taste nearly as good.
“Oh my!! These are the BEST peanut butter cookies ever!! I will literally need a whole jar of peanut butter just for these cookies! They are so delicious and easy to make! Thanks for this recipe!” — Brenda M.
Ingredients in Flourless Peanut Butter Cookies
To make these peanut butter cookies with no flour, you’ll need:
- Egg – I haven’t tested substituting the egg in this recipe and don’t recommend it.
- Creamy peanut butter – to switch up the flavor of this recipe, use honey roasted peanut butter instead of regular. You want to use Jif, Skippy, or similar rather than natural or homemade peanut butter. Sometimes natural versions work fine but not always; classic peanut butter is more trustworthy
- Light brown sugar
- Granulated sugar
- Vanilla extract
- Baking soda
- Salt

How to Make Flourless Peanut Butter Cookies
Never made flourless cookies before? They’re easy!
Here’s how these flourless, butterless peanut butter cookies are made:
- Whisk all the ingredients in a large mixing bowl until smooth. There’s not need for a stand mixer!
- Use a 2-inch cookie scoop to shape the dough into mounds, place the dough balls on a large plate, cover them with plastic wrap, and chill in the fridge.
- Arrange the peanut butter cookie dough balls on a baking sheet liked with Silpat mats or greased with cooking spray, leaving space between each piece. Flatten the cookies slightly, and use a fork to make a criss-cross pattern if desired.
- Bake at 350F until the edges are set and the tops are barely set. Be careful not to overbake!
- Allow the cookies to cool completely on the baking sheet, and enjoy!

Recipe FAQs
No, a no-stir “traditional” peanut butter like Jif or Skippy is best in this flourless peanut butter cookie recipe. Homemade or natural peanut butters don’t always work in baked goods.
I personally prefer using creamy peanut butter in my baked goods, but I bet crunchy would work just fine here. If you try this out, leave me a comment letting me know what you thought!
If you wanted to take these PB cookies to the next level, feel free to add chocolate chips, peanut butter chips, butterscotch chips, or chopped nuts. You may add up to 1 cup of mix-ins.
I’ve only made this recipe as written, so I can’t speak to what sugar substitutes you could use. However, a few readers have reported success using Splenda, but having never tested it myself I don’t know if it will yield the same results.
Most likely, but just keep in mind that natural nut butters such as almond butter and cashew butter only sometimes work for me in baked goods. So use your best judgment, and definitely chill the dough still!
The nice thing about this recipe is that it doesn’t make too many cookies, just 11 or 12, which for me is a good thing. The more I have around, the more I’m tempted to devour! However, you can easily double or triple the recipe depending on how many people you need to feed.
Baked flourless, gluten free peanut butter cookies will stay fresh in an airtight container at room temperature for up to 1 week.
Yes, both the flourless cookie dough and the baked cookies freeze extremely well. If baking frozen cookie dough, add a minute or two to the total bake time.
Yes! You can store unbaked cookie dough in an airtight container in the refrigerator for up to 5 days. Then, just pull it out, and bake as normal whenever a craving strikes.

The Best Flourless Peanut Butter Cookies
Equipment
- 1 Large Mixing Bowl
- 1 Baking Sheet
Ingredients
- 1 large egg
- 1 cup creamy classic-style peanut butter or honey-roasted peanut butter*
- ¾ cup light brown sugar, packed
- ¼ cup granulated sugar
- 2 teaspoons vanilla extract
- ½ teaspoon baking soda
- ½ teaspoon salt
Instructions
- To a large mixing bowl, add all ingredients and stir to combine using a spoon. It takes some elbow grease and it’s okay for the dough to be slightly granular because the sugar absorbs into the dough over time as the dough chills.
- Using a medium 2-inch cookie scoop, form two-tablespoon mounds, place mounds on a large plate, cover with plasticwrap, and refrigerate for at least 3 hours, or up to 5 days, before baking. Do not bake with warm dough because cookies will spread and bake thinner and flatter.
- Preheat oven to 350F, line a baking sheet with a Silpat or spray with cooking spray. Place mounds on baking sheet, spaced at least 2 inches apart (I bake 8 cookies per sheet), flatten slightly using a fork to make a criss-cross pattern if desired.
- Bake for 8 minutes, or until edges are set and tops are barely set, even if slightly underbaked and glossy in the center. Cookies firm up as they cool; don’t overbake.
- Allow cookies to cool on baking sheet for about 10 minutes before serving. I let them cool on the baking sheet and don’t use a rack.
Notes
- *You want to use Jif, Skippy, or similar rather than natural or homemade peanut butter. Sometimes natural versions work fine but not always; classic peanut butter is more trustworthy. I use honey-roasted.
- Cookies will keep airtight at room temperature for up to 1 week or in the freezer for up to 6 months.
- Alternatively, unbaked cookie dough can be stored in an airtight container in the refrigerator for up to 5 days, so consider baking only as many cookies as desired and save the remaining dough to be baked in the future when desired.

Thanks for the 5 star review, Danielle, and I’m glad this will be your forever-recipe for peanut butter cookies!
1st time I made them followed recipe exactly, well maybe a touch more salt cause I like PB cookies on the salty side. and OMG! So good!!! Got rave reviews from many people.
2nd time I made them was for a vegan friend so replaced the egg with a flax egg and it works perfectly! I also added a little chocolate drizzle on top made from coconut oil, cacao powder and powdered sugar…that was amazing too.
Thanks so much for your great recipe…it’s probably going to be used way too often in my home 😬
Thanks for the 5 star review, Patty, and I am glad that you have tried this a couple times and even were able to use a flax egg so they’re vegan! Great to hear and that you will use this recipe often! 😉
