My keto peanut butter cookies need just 3 ingredients and taste like classic peanut butter cookies! No flour and no grains needed; they take less than 10 minutes to make!

keto peanut butter cookies that taste like the classic

Peanut butter cookies are a household classic, and these low-carb peanut butter cookies look and taste like the real thing- packed with rich peanut butter flavor.
I didn’t reinvent the wheel. I simply took the famous 3-ingredient cookie from the back of the peanut butter jar and swapped the sugar for allulose (my favorite keto sweetener) because it’s the only one that keeps the cookies soft the next day. Here’s why I love them:
- No flour. Unlike traditional cookies, these have no flour or grains, but you’d never know it.
- Ready in 10 minutes. From mixing the dough to pulling it out of the oven, I love that the whole process takes ten minutes.
- Perfect texture. Crisp around the edges and soft, chewy in the center, they practically melt in your mouth.

Key Ingredients
- Peanut butter. Smooth, drippy peanut butter is best. Aim for the all-natural kind with no added sugar. I really like Whole Foods 365 or Trader Joe’s smooth peanut butter.
- Keto sweetener. I’ve tested every mainstream low-carb sweetener, and allulose is the only one that yields soft and chewy cookies. Monk fruit and erythritol left things super grainy, and sometimes with an aftertaste.
- Egg. Room-temperature eggs mix more easily into the batter.
- Optional add-ons. Sugar-free chocolate chips are my go-to, but I also like vanilla and/or sea salt.

How to make keto peanut butter cookies
Step 1- Make the batter. Start by adding the peanut butter, sweetener, and egg into a large bowl and mixing until combined.
Step 2- Prep the cookies. Next, use a 2-inch cookie scoop to drop dough portions onto a lined baking sheet or silicone baking mat. Cross each ball of dough with a fork to form a criss-cross shape.
Step 3- Bake. Bake the cookies for 10-12 minutes or until just firm around the edges. Let the cookies cool in the pan or on a cooling rack completely.
Arman’s recipe tips
- Don’t overbake them. The cookies will look slightly underdone when you take them out of the oven, but they’ll continue to firm up as they cool. If you wait until they look fully baked, they’ll end up dry.
- Use smooth, drippy peanut butter. I’ve found that crunchy or extra-thick peanut butter makes the dough too stiff and the cookies don’t spread well.
- Try a different nut or seed butter. I’ve also made these with almond butter, cashew butter, and tahini, and they all work well.
- Want a thicker cookie? Stir in 1/2 cup of almond flour or coconut flour. The cookies bake up a little sturdier with a cakier center.
Storage instructions
To store: Place peanut butter cookies in an airtight container at room temperature. They will keep fresh for up to 2 weeks. Alternatively, you can refrigerate them, and those will keep for up to 1 month.
To freeze: Place cookies in a Ziploc bag and store in the freezer for up to 6 months.

OMG these are so good- just like the classic ones!
So great to hear that, Karine!
Thrilled to have stumbled upon your website. My husband is a type 1 diabetic and misses eating sweets. I made these and they are fantastic! I have the keto cheesecake in the fridge using the peanut butter cookies for the crust and cannot wait to try it! Thank you for creating/sharing wonderful tasting lower carb dessert options!
These were so easy to make and they taste so good! I shared them with my friends, and they all loved them also.
Pretty good. I’ve burnt it at least 3 times though.
These peanut butter cookies were so good! I am pre-diabetic so there’s a lot of desserts I can’t eat This was so easy. Even my husband and my friends love them.
The best keto peanut butter cookies I’ve ever made.
I like to throw a little cinnamon in the batter and press a half pecan or a few chocolate chips in each before baking, awesome
Yum!!!
Omg, so easy to make and ridiculously delicious! If you love peanut butter cookies, you owe it to yourself to try these cookies. You’ll realize keto can indeed be a healthy lifestyle and not a ‘diet.’
Absolutely DELICIOUS!!! Quick and easy – although it took me considerably longer than 1 minute to dig out one cup of peanut butter since I cleaned out two open jars (one creamy and one chunky). I used 1/3 Cup of Erythritol and 1/3 Cup of stevia and a cookie scoop which managed to produce 15 cookies on a single 11 x 17 pan. Only baked them for 10 minutes, but I think they probably should have had another minute or two. My husband and I are feasting on these. We decided to have two each. A batch of 15 cookies only have 64 calories each, so we had 128 calories for dessert!!
Love all of your recipes. My daughter and I agree you have the best KETO recipes on the web. Thanks so much for your love of food, and sharing your talents with the common folk. We are going to feast this next week on your “Will you marry me” chicken. Can’t wait to try it.
These are delicious and so very easy to make! I used half chunky and half plain peanut butter because that’s what I had on hand. Then, when cooled, I melted some chocolate chips to spread over the tops. I trust that every recipe I find on this site will be outstanding!
These are delicious, simple and they never last at my house. I like to add sugar-free chocolate chips which makes them doubly delicious!
Best homemade peanut butter cookies. A huge hit in my family
These are delicious. I may use less sugar next time.
These are so good! I sprinkled a little sea salt on top before baking them and drizzled melted semi sweet chocolate on half of them and white chocolate on the other half. Yum!! Thanks so much for this recipe, Arman!
Love, love, love these cookies! Thank you so much for sharing your recipes:)
Wow…to the individual who said the cookies were nasty. Had to be something on your end. I have people paying me to make them so they can have them for parties. These cookies are phenomenal.
