Does Gluten Free Mean Keto?
For those that are new to the peanut butter cookie realm there is a few things you should know. While most 3 ingredient peanut butter cookies are gluten free, they certainly are not sugar free! Standard three ingredient peanut butter cookies will use a 1/2 cup of sugar to make just 12 cookies. That’s 100 grams of carbs total, or 8 grams of pure sugar per cookie. Low carb peanut butter cookies use sugar free sweeteners like erythritol to sub all the carbs that come from sugar in most peanut butter cookies. Just because a recipe you find is gluten free, that does not make it keto. Sugar is one of the biggest enemies on a keto diet, so do yourself a favor and just stick to these 100% keto approved low carb peanut butter cookies.

Is Peanut Butter Keto?
Natural peanut butter is normally made of just peanuts, or peanuts and salt. Despite what some people say, naturally made peanut butter does fit in a keto diet. Peanuts are technically legumes and not nuts, meaning they are grown underground and are higher in omegas 6’s. This is normally why keto dieters avoid them. High levels of omega 6’s in the body can cause excess inflammation. However a little bit of peanut butter from time to time is 100% okay on keto.
Peanut butter is a great source of fat and protein, all while being low in carbs if you choose a sugar free variety. The most important part is that you buy straight peanut butter and not any added sugars or oils in it. A good rule of thumb is if a peanut butter says “no stir”, it’s not keto. To make a peanut butter no stir you need to add: bad oils like palm or vegetable oils, refined white sugar, and extra emulsifiers. These are bad carbs and ingredients that will cause inflammation and more harm than good.
What Brand of Peanut Butter is Keto?
Now that you know natural unsweetened peanut butter CAN fit in a keto diet, let’s talk the best peanut butter brands on the market. Our favorite keto peanut butter is Crazy Richards or Kirkland Signature Organic Peanut Butter. They both have only one or two ingredients: peanuts and salt. Crazy Richards peanut butter can be purchased at Walmart and is only 4 net carbs per two tablespoons. Kirkland Signature peanut butter (aka Costco) is 5 net carbs per two tablespoons. The great thing about Kirkland Signature is that the price is amazing for the amount you get. They also have organic peanut butter which is important because peanuts are legumes that can absorb pesticides through the ground as they grow.
Peanut butter CAN be keto and these keto peanut butter cookies take your favorite treat to a whole new level.
How Many Carbs are in Peanut Butter Cookies?
This recipe makes 12-15 cookies (usually about 13 medium sized cookies).
Per Serving, 1 cookie: Calories 132, 11 grams of fat, 6 grams of protein, 3 net carbs.
These keto peanut butter cookies have a total of 4 carbs and 1 fiber (3net), which makes these the perfect keto treat for anytime of day. The number of carbs will be very dependent on what peanut butter you choose though, so shop wisely.
What Sweetener to Use
The sugar free sweetener you use really depends on preference. The most important things for this recipe is that your sweetener is sugar free and in powdered form. I’ll breakdown some of most common sweeteners so you can decide which one works best for you.
Erythritol is a common keto cookie ingredient. More often than not you will see a cookie recipe with erythritol because it is one of the most affordable keto sweeteners for a low net carb count. If you are looking for the most affordable option out of the three, this is it.
Monk fruit is a highly concentrated plant based sweetener like stevia. It is a bit more expensive, but well worth the cost. It has a slight vanilla flavor which is lovely in a dessert recipe. The only issue is that monk fruit being a liquid originally has to be combined with something else cheaper to become a powder. This can cause a blood sugar spike depending on what you purchase it with.
You can purchase allulose most commonly off of amazon. Most brands only sell it granular though so you will need to pulse it a few times in a coffee grinder. It is reasonably priced, but still a rare sweetener that makes it more expensive per pound than erythritol.
Making Powdered Sweetener
If you only have granular sweetener that’s okay. When using granular sweetener you’ll want to pulse it in a coffee grinder a few times to get that powdery consistency.
Any of these keto sweeteners will work, it really just comes down to price and preference. Erythritol, while cheaper than the other two, works just fine in this keto peanut butter cookies recipe for someone on a budget. If you are looking to try something new, allulose and monk fruit are great fancy ingredients to try out.
How to Make Keto Peanut Butter Cookies
If you’ve been looking for a super easy recipe to make peanut butter cookies keto, try making this peanut butter cookies recipe. They are some of these easiest cookies you’ll ever make, with such a short total time you’ll be eating cookies in minutes. Keto peanut butter cookies have a prep time of 5 minutes, cook time of 15 minutes, and a total time of only 20 minutes. That means it’s only 20 minutes before you can demolish some delicious goodies!
- Baking Sheets– Like any cookie recipe you will need a baking sheet. For this cookie recipe we’ll often prepare and line a cookie sheet or two so that we can make tons of cookies at once and freeze them.
- Parchment Paper– We always have parchment paper on hand for easy cleanup. Plus if you’re anything like us, parchment paper can be a pain to fit in your baking sheets. That’s why we linked an option for pre-cut papers!
Since these keto peanut butter cookies only have 3 ingredients we really like to stress quality. The simpler a recipe, the more you need to focus on tasty ingredients. Each ingredient will have its own place to shine.
- 1 cup Peanut Butter (sugar free)- This is the main ingredient because you can’t make some keto peanut butter cookies without peanut butter! If you aren’t sure what peanut butter is keto approved checkout the information above. The runnier your peanut butter the better for this recipe.
- 1 large Egg- We love pasture raised eggs because they have a super golden yolk and quality fat content. The egg will also help to bind the keto peanut butter cookies so they are still slightly fluffy inside. We recommend a room temperature egg so that the peanut butter doesn’t go stiff.
- 1/3 cup Confectioner Swerve or ½ cup powdered monk fruit/allulose– This cookie recipe is gluten free and flourless. Instead of using something like coconut flour, the only real bulking agent is this peanut butter sweetener. You will use the powdered sweetener to bring that delicious peanut butter cookie together, so the cookie dough is not too runny. If you like it less sweet try 1/4 cup instead. Want them sweeter? Use a 1/2 cup.
Note: Natural peanut butters are very runny and will work well for this recipe. If you choose to use a peanut butter that’s on the thicker side, you may want to melt it in the microwave for 15-20 seconds first.
- 1 Tbsp Almond flour– Almond Flour will make a bit of a denser cookie, but is not required. These keto peanut butter cookies are just as good gluten free and flour free!
- 1 tsp vanilla extract– Vanilla Extract is a great way to add a bit of extra flavor. Plus vanilla extract brings out the nutty-ness of peanut butter.
- Flakey Salt- A sprinkle of flakey salt on top of the cookies before baking adds a lovely touch! Just make sure if your peanut butter already has salt that you don’t add too much on top.
1. Preheat oven to 350 F and line a baking sheet with parchment paper.
2. In a medium mixing bowl combine the peanut butter and room temperature egg. Once you have a smooth batter mix in the sugar free monk fruit or erythritol sweetener making sure there are no clumps. – If your egg is not room temperature you can place it in a mixing bowl with warm water for 2-3 minutes first. If you want vanilla or almond flour add that in now too.
3. Scoop heaping one tablespoon-sized pieces of dough into 12-15 balls (To make it easier try a cookie scoop! . Place the balls 2 inches apart on the parchment paper lined baking sheet. Then flatten the cookie dough in a criss-cross pattern with a fork. – Now would be the time to add a sprinkle of salt if you’d like.
4. Place the cookie sheet into the oven and bake for 12-15 minutes until edges of cookies are golden brown
5. Let cool completely before eating.
