You’ve probably tried the ever popular 3-ingredient low carb cookies. Made with only your choice of nut butter, egg, and your favorite low carb sweetener, they are gluten free and low carb.

Unfortunately, the texture of flourless cookies just isn’t the same as those made with flour. And using almond butter or sun butter doesn’t give you that peanut butter taste in quite the same way.

That’s how these keto friendly coconut flour peanut butter cookies came to be...there needed to be a classic peanut butter cookie that worked on the keto diet.

Ingredients In Keto Peanut Butter Cookies

So what do you need to make these delightful low carb peanut butter cookies?

• Coconut flour
• Natural peanut butter (unsweetened)
• Stevia concentrated powder
• Low carb sugar substitute
• Butter
• Eggs
• Salt
• Vanilla extract

While there are more than 3 ingredients here, it’s still a very simple recipe to make. 

And the result? 

Not only do you have gluten free keto cookies you can eat without guilt, their taste and texture are like the ones you remember from childhood.

When I first made the cookies, I used all Swerve. However, the cooling taste was definitely present.

I recommend reducing the Swerve and adding in stevia concentrate. The sweetener blend makes the cooling effect of erythritol unnoticeable.

Depending on how sweet you want these low carb peanut butter cookies, you can add anywhere from ½ to ¾ cup sugar equivalent. The amount of sweetener I used in the recipe is closer to ½ cup of sugar.

Although I thought the coconut flour amount was just right, you may want to adjust it slightly to get the texture you prefer. I like the cookie crisp on the outside and a bit softer in the middle.

Coconut Flour

The inclusion of coconut flour is what makes these cookies have the texture they do. Coconut flour is incredibly absorbent and can’t be exchanged with other low carb fours equally, so if you don’t have it on hand you’ll need to pick some up on your next trip!

Coconut flour does vary by brand. So, you may need more or less of it. 

These cookies will come out just a bit crisp on the outside and perfectly gooey in the middle. If you make your dough, however, and the texture seems off to you don’t be afraid to make a test batch and then add a sprinkle or two more flour to get the texture that’s pleasing to your palate.

If you’re worried about having an overwhelming coconut taste, don’t be. There’s more than enough peanut butter to make sure that doesn’t happen!

Butter

Butter is the traditional peanut butter cookie ingredient, so that’s what this recipe calls for (we want to keep the flavor as authentic as possible, after all).

However if you wanted gluten free, dairy free peanut butter cookies all you would need to do is substitute coconut oil.

You could use any kind you have on hand, but refined is better if you don’t want coconut undertones in your finished cookies.

The Best Sweetener For Sugar Free Peanut Butter Cookies

Low carb sweeteners are interesting. 

The first batch of keto peanut butter cookies had all Swerve in them. They were good, but that notorious cooling taste was definitely present.

That’s why the final recipe actually calls for a mix of sweeteners. When you combine the Swerve or another erythritol blend with concentrated stevia powder, the cooler effect becomes unnoticeable.

Keto baking tip: Don’t cut the salt out of your low carb sweets recipes! It also helps reduce any aftertaste you might notice from sugar free sweeteners. If you’re peanut butter is salted, however, you can leave it out.

If you’ve got a real sweet tooth, you can absolutely increase the sweetener blend quantity. The amount of sweetener used in this is comparable ½ cup of sugar, but if you’d like more you can add another teaspoon or two.

If you need to switch out the granulated sweetener for a different option because of what you have on hand, you can refer to this low carb sweetener chart.

To modify this recipe into a flourless cookie, you'd need to omit the coconut flour, butter, and egg. And, the sweetener would likely need to be reduced to accommodate.

But, I was looking for low carb peanut butter cookies that had the texture of flour based ones. The coconut flour is needed to achieve that.

It’s best to tweak the sweetener and coconut flour until you get something that works best for your ingredients.

Baking Your Coconut Flour Peanut Butter Cookies

When you make up your cookie dough, you’ll roll it into a ball and place it on your baking sheet. Before you use a fork to make that nostalgic criss cross pattern, flatten the balls just a little bit.

Unlike regular peanut butter cookie dough, this batter doesn’t spread much in the oven. Because of this, you’ll need to flatten them very thin before baking if you like them that way.

Once they are all done cooking, gently remove them to a cooling rack and allow them to cool completely.

If you’d like to make a peanut butter blossom cookie, take a peek at this recipe that tops a peanut butter flavored cookie with homemade chocolate kisses.

You can also make thumbprint cookies filled with sugar free chocolate chips to satisfy your sweet tooth. All of these cookie recipes would be perfect for holiday treats!

Making Ahead & Storing Your Peanut Butter Cookies

You can make the dough up ahead of time and freeze it to bake them fresh, if you'd like. The easiest way to do this is to roll the balls and flash freeze them on a cookie sheet before putting them in a freezer bag.

Before cooking, lay the balls on the baking sheet and let them come to room temperature so that they cook well.

Alternately, you can cook up a large batch and store them in an airtight container. They should keep well for 2-3 days at room temperature and longer in the fridge.
