With only 4 basic ingredients, these Keto Flourless Peanut Butter Cookies are the easiest (and tastiest!) Keto treats around! They're slightly crisp on the outside with a melt-in-your-mouth center that will have you swooning.
If you love peanut butter (or any nut butter) as I do, these Keto Flouless Peanut Butter Cookies are a must! They're slightly crisp on the outside with a soft and chewy center that will have you swooning.
And with only 2 net carbs a pop, they're a treat you don't have to feel guilty about.
Plus, they're super fast and easy to whip up! They're perfect for a last-minute treat or if you have unexpected guests. They also freeze well if you would like to make a big batch to keep in the freezer.
The sweetener
For the sweetener, you need to use an erythritol-based sweetener for the cookies to have their crunch and hold together well.
However, I’ve noticed that the cooling-like aftertaste erythritol sometimes lends is more noticeable in these cookies. This why I recommend a Monk Fruit Erythritol Blend.
The erythritol will cause them to bake up perfectly, while the monk fruit drastically reduces the aftertaste – it’s a win-win!
Or if you're Paleo, coconut palm sugar works well.
The nut butter
Nut butter can vary - a lot! Whatever kind you use - be it peanut, almond, sunbutter, etc.. - it needs to be smooth and creamy.
If you use a nut butter that is dry or hard, the cookies will not turn out well.
If the nut butter has oil sitting on top, be sure to stir it in really well before measuring. I suggest using a salted, unsweetened variety.
Easy instructions
Start by beating an egg and some sweetener in a large bowl with an electric mixer until well combined and fluffy, around 2 to 3 minutes.
As with most flourless peanut butter cookies, these have a 1:1 ratio of peanut butter to sugar. If you've been Keto for a while though, this may be way too sweet for you.
Feel free to reduce it down to ½ cup if you prefer less sweet desserts.
Then, add 1 cup of nut butter of choice, baking soda, and pure vanilla. The batter with thick and a bit crumbly, but this is OK.
Roll the batter into Tablespoon-sized balls and place them on a lined baking sheet. The batter should make around 15 to 16 cookies.
Then, use a fork to slightly press them down and make a criss-cross pattern. The criss-cross pattern is a must when making peanut butter cookies, you just hafta do it, lol!
After that, preheat the oven to 350 degrees and place the cookies in the freezer for at least 20 minutes while the oven preheats.
Why freeze cookies before baking
I freeze these before baking because this causes them to spread less and have a better texture. This is because the chilled fat in the cookies takes longer to melt than room-temperature fat.
The longer it takes the fat to melt, the less the cookies spread. They also turn out softer and chewier making for a much better texture.
Bake for 11-15 minutes, or until the edges are lightly browned and set. Do not over-bake or they'll lose their soft, melt-in-your-mouth texture!
If you're a fan of sea salt and would like them to be more savory, feel free to sprinkle some flaky sea salt on them halfway through baking. I personally love desserts with sea salt (like these truffles!) so this is a step I never miss!
Top tips
- Be careful not to over-bake. Bake until lightly golden and set. If they're over-baked, they will be crumbly instead of soft and tender.
- These work with any nut butter, not just peanut butter! Just be sure the texture is soft and smooth. If the nut butter is dry or hard, the cookies will not turn out well.
- If there's oil sitting on top of the nut butter, stir it in really well before measuring. Sometimes nut butter can be hard to stir after it has separated. If this happens I process my peanut or almond butter in a food processor until it's well blended and creamy. Then, it should be easy to measure and stay soft and smooth until the jar is empty.
- I have never tried these with crunchy nut butter or homemade peanut butter or almond butter. If you give either of them a shot let me know how they turn out.
- You have to make a criss-cross pattern on top of the cookies. It's an unspoken rule when making peanut cookies, lol!
- Feel free to sprinkle these with flaky sea salt halfway through baking to make them a bit more savory.

📖 Recipe
(The Easiest!) Flourless, Keto Peanut Butter Cookies
Ingredients
- 1 Cup Unsweetened, Salted Creamy Peanut Butter Or Nut Butter Of Choice - be sure it's soft and creamy, not dry or hard
- 1 Cup Monk Fruit Erythritol Blend Sweetener - (see notes) or coconut palm sugar for Paleo. This makes a very sweet cookie, reduce down to ½ cup if you prefer less-sweet desserts
- 1 Large Egg
- 1 tsp. Baking Soda
- 1 tsp. Pure Vanilla
- Flaky Sea Salt - optional
Instructions
- Preheat oven to 350 degrees and line a baking sheet with parchment paper or baking mat.
- Add sweetener and egg to a large mixing bowl and beat with an electric mixer until light and fluffy, around 3 minutes. Add the baking soda, peanut butter, and vanilla. Beat until well combined and fluffy.
- Form dough into 1-inch sized balls, place on prepared baking sheet, and slightly press down on each one with a fork creating a criss-cross pattern and patch up the edges as needed. Freeze for 15 minutes before baking.
- Bake 11-14 minutes or until lightly golden and set. Do not over-bake as this will make the cookies crumbly instead of soft. Sprinkle with flaky sea salt half-way through baking to make them a bit more savory.
- Cool completely. Store covered in the fridge for 3 to 4 days, or in the freezer up to 3 months.
Notes
- Be careful not to over-bake. Bake until lightly golden and set. If they're over-baked, they will be crumbly instead of soft and tender.
- These work with any nut butter, not just peanut butter! Just be sure the texture is soft and smooth. If the nut butter is dry or hard, the cookies will not turn out well.
