To ensure the success of your recipe, it’s advisable to keep your ingredients at room temperature. This helps them mix and combine better, resulting in a smoother texture and more even baking or cooking. Additionally, cold ingredients can alter the consistency of your batter or dough, affecting the end result of your dish.

These cookies are a treat for the senses, combining chewiness and crunchiness with a distinct peanut butter flavor that is sure to leave your taste buds tingling. Not only are they satisfying, but they are also filling, making them the perfect snack to enjoy any time of day. If you’re interested in trying your hand at making these delicious treats yourself, then let’s dive into the recipe. With simple ingredients and easy-to-follow instructions, you’ll have a batch of these scrumptious cookies in no time!


To make delicious keto cookies without flour, you will need a few key ingredients. Firstly, you will need a sugar substitute such as erythritol or stevia to sweeten the cookies while keeping them low-carb. Adding unsweetened cocoa powder can give your cookies a rich chocolatey taste, while vanilla extract can provide a subtle flavor. Finally, incorporating eggs, butter, and coconut flour into your mixture can help bind everything together and create a soft and chewy cookie.

Peanut Butter – I utilized a creamy peanut butter but feel free to use the crunchy variant. Select a brand that solely consists of one ingredient – peanuts. I use Kirkland creamy Organic. It is important to always verify the label! Many brands frequently include palm oil and sugar.

Sweetener – Sugar-free sweeteners are essential for making sugar free peanut butter cookies. One option is monk fruit, However, any sweetener, can be used.

Egg – When baking or cooking with eggs, it is important to use the right size and temperature. For this particular recipe, a large egg at room temperature is recommended. Room temperature eggs mix better with other ingredients and create a more uniform texture in baked goods. If you forget to take your eggs out ahead of time, simply place them in a bowl of warm water for a few minutes to bring them to room temperature before using.

Pure Vanilla – 1 teaspoon pure vanilla extract. I use Kirkland Signature Pure Vanilla, However you can use any you prefer.

Cinnamon and sea salt – are both optional ingredients for peanut butter cookies, adding a sprinkle of sea salt can enhance the flavor of the cookies if your peanut butter lacks salt. Incorporating it into the dough can also help create a more even distribution of salt throughout the batch.

Sea salt is also a healthier alternative to regular table salt as it contains trace minerals that are beneficial to the body. Cinnamon, on the other hand, adds a warm and comforting flavor to the cookies and has been associated with numerous health benefits such as reducing inflammation and lowering blood sugar levels. Ultimately, it depends on personal preference which ingredient you choose to add or omit from your peanut butter cookie recipe.


In this section, you will find a detailed set of instructions that will guide you through the process of making this recipe.

Allow me to demonstrate the process of creating the most exquisite keto-friendly peanut butter cookies.

To begin, it is important to preheat the oven and prepare a baking sheet by lining it with parchment paper.

Step 1

Combine all ingredients in a big mixing bowl, using a fork to stir them together.

Step 2

Create small dough balls by using your hands and place them on either a cookie sheet lined with parchment paper or a silicone baking mat.

Alternatively, you can utilize a cookie scoop to easily drop spoonful’s of the dough onto the baking sheet.

The combination results in 20 petite cookies weighing approximately 15 grams each.

Step 3

After mastering the recipe for these cookies, the only slightly challenging aspect is creating the beautiful criss-cross design on their surface. To achieve this effect, use a fork to press down on the dough once it’s been placed on the baking sheet.

Then, turn the fork 90 degrees and press down again to create a crosshatch pattern. This technique not only gives the cookies their signature look but also helps them bake evenly. If you’re feeling adventurous, try experimenting with different patterns or shapes to make your cookies stand out even more.

Step 4

To bake cookies to perfection, place them in the oven and allow them to cook until they achieve a golden brown hue. Ensure that the edges are firm, as this is an indicator that they have been properly baked through.

The baking time can vary depending on the type of cookie and the oven temperature, so keep a close eye on them while they bake to avoid overcooking or burning. Once they are ready, remove from the oven and let them cool before enjoying!


To create the cross-hatch design, I prefer moistening the fork before pressing it onto the dough. This technique helps in preventing the cookie dough from sticking to the fork. As I progress through each batch, I make sure to clean and dampen the fork as required.

When baking low-carb cookies, it is crucial to exercise patience and allow them to cool completely before handling them. Because gluten is absent from these cookies, they are initially soft and fragile once removed from the oven. However, as they cool down, they firm up, making them much easier to handle and less prone to breaking apart. Rushing this step can result in crumbly, unappetizing cookies that don’t hold together well.


Chocolate chips are a fantastic addition to any peanut butter cookie. There are two ways to incorporate them into the dough – either by using sugar-free chocolate chips or by chopping up a few squares of dark chocolate. For the best results, I will sometimes use Dark chocolate with at least 90% cocoa content. Additionally, you can also experiment with different types of flour to give your cookies a unique twist. For example, instead of traditional flour, you can try using almond flour (or almond meal), which is simply ground-up almonds blended into a fine texture resembling flour. This substitution can add a nutty flavor and a slightly different texture to your cookies. If you prefer to use pecan flour, sunflower flour, or cashew flour, I think these would be fine but haven’t tried, so be sure to report back if you do experiment.

Enhance the chocolate flavor by coating half of the cookie with melted dark chocolate (ensure it has at least 90% cocoa solids). However, ensure that the cookies are completely cooled prior to dipping.

Alter the consistency. In case you favor a crispy consistency, feel at liberty to utilize crunchy peanut butter as a substitute for creamy. You might even consider employing a cookie stamp with a pattern..

Achieve a higher rise by incorporating ½ teaspoon of baking powder into the cookie dough, which will give it a more airy and delicate consistency. I recently tested this method and was pleased with the outcome, as the cookies expanded beautifully during baking.

Change the flavor. Once in a while, I even tried out a delicious seasonal twist by adding a teaspoon of pumpkin spice (a mix of cinnamon, nutmeg, ginger, and cloves).

Frequently Asked Questions about Recipe

This specific recipe can be used with almond butter, cashew butter, or any other kind of nut or seed butter. In fact, I used it to create my delicious 3 ingredient Keto Almond Butter Cookies!

If you want a soft-centered cookie, bake for approximately 8 minutes.

If you prefer crunchy cookies, keep them in the oven for 10 minutes.

To make homemade peanut butter, you will need a food processor or a high-speed blender. Simply blend the peanuts on high speed for a few minutes until they release their natural oils and become smooth butter. For crunchy peanut butter, add some crushed peanuts.

The sweetener is not necessary for this recipe. If you want sugarless peanut butter cookies, just leave out any sugar substitute. However, remember to include sea salt and cinnamon for a flavorful taste.

Serving Suggestion

I enjoy indulging in one of these cookies while savoring a glass of Oat milk. Meanwhile, my husband prefers to submerge his cookie in a glass of chilled almond milk.

It’s comforting to be aware that they are also an excellent snack for when you’re on the move because they are durable and convenient to carry. During our long hikes, my husband, furbabies, and I pack these in our backpacks to maintain our energy levels.

If you’re a food lover, here’s a delicious suggestion: Take two cookies and spread sugar-free Nutella in the center. This combination is like a keto-friendly version of Oreos, with the delectable taste of peanut butter and chocolate. Besides being a tasty treat, sugar-free Nutella is an excellent alternative for those who want to cut down on their sugar intake. It is made with hazelnuts, cocoa powder, and sweeteners like erythritol or stevia, making it perfect for those following a low-carb or keto diet. Plus, hazelnuts are rich in healthy fats and antioxidants, providing numerous health benefits such as improved heart health and reduced inflammation.


To maintain the freshness of the cookies, place them in a sealed container and store at room temperature for a maximum of 2 weeks. Alternatively, if stored in the refrigerator, the cookies can stay fresh for a period of 3-4 weeks.

You also have the option of storing them in the freezer for a maximum of 3 months. It is recommended to freeze them on a baking tray lined with parchment paper and subsequently transfer them into a zip lock bag after they have frozen. By doing this, you can prevent the cookies from sticking together.

To thaw frozen cookies, you can either leave them on the kitchen counter or place them in the refrigerator overnight.

Contrary to popular belief, peanuts are not nuts, but rather legumes. Legumes are plants that bear fruit in the form of pods that split open to reveal their seeds. Peanuts grow underground and belong to the same family as beans, lentils, and peas.

Despite this classification, many people still consider peanuts to be nuts due to their similar taste and texture when roasted. However, scientifically speaking, they are not classified as tree nuts like almonds or pecans. Nonetheless, whether we group peanuts with true nuts or legumes is a matter of personal opinion.
