THE BEST KETO PEANUT BUTTER COOKIES

This low-carb peanut butter cookie recipe is one of my favorite keto desserts. I modified my mom’s recipe and made a keto cookie recipe with the flavor and consistency of classic peanut butter cookies. A little chewy, a little crunchy, a lot of tasty!

When I first started my keto journey, I struggled with giving up some of my favorite treats, especially my mom’s classic peanut butter cookies. One of the keys to success on the keto diet is finding great substitutes for the foods you crave. So, I decided to experiment in the kitchen and create a low-carb version of her recipe.

After a few trial batches, I finally nailed it! These keto peanut butter cookies remind me of the amazing flavors of my childhood while keeping me on track with my health journey.

Prepare yourself for the best keto peanut butter cookie recipe EVER! The recipe reminds me so much of my childhood in Georgia. I can almost smell my mom’s warm peanut butter cookies cooling off on the kitchen island.

These cookies are irresistible, nutty, slightly salty, and just a little sweet, with a soft and crumbly texture. Best of all, with the reduced carb content and ease of preparation, this low-carb recipe will let you indulge in a delicious sweet treat while sticking to your keto or low-carb lifestyle.

ARE SUGAR-FREE PEANUT BUTTER COOKIES ACTUALLY TASTY?

Absolutely! These low-carb peanut butter cookies are known for their rich, nutty flavor and satisfying sweetness. I can’t speak for all sugar-free peanut butter cookie recipes, but these are delicious.

HOW TO MAKE PEANUT BUTTER COOKIES LOW-CARB AND KETO-FRIENDLY

To make this recipe suitable for the keto diet, I made a few changes. Instead of using regular flour, I switched to coconut flour. It’s important to note that coconut flour isn’t a direct replacement for all-purpose flour, so I adjusted the quantity accordingly with a few other tweaks. I swapped out regular sugar for Wholesome Yum Monk Fruit Allulose Blend. This is my favorite sugar substitute to bake with.

While these low-carb peanut butter cookies might not exactly mimic the fantastic taste of my mom’s cookies, they’re a great option that won’t fill you up with lots of carbs and sugar. They offer an excellent way to enjoy some dessert goodness without kicking yourself out of ketosis.

Having a collection of keto-friendly dessert treats like these on hand simplifies the journey of following a keto lifestyle. It’s a great reminder that we can savor sweets and stay on track!

INGREDIENTS FOR PEANUT BUTTER COOKIES

  • Natural Peanut Butter: Gives the cookie its nutty flavor and helps hold everything together. I used Smucker’s Natural Crunchy Peanut Butter for this recipe, but feel free to use your preferred brand.
  • Egg: Binds the ingredients and makes the cookie soft and yummy
  • Wholesome Yum Monk Fruit Allulose Blend: Adds sweetness without regular sugar.
  • Coconut Flour: Adds texture and a bit of fluffiness to the cookies. If you prefer, you can use almond flour, but remember, it’s a 1:4 ratio, and it isn’t a perfect science. (¼ cup coconut flour = 1 cup almond flour).
  • Coconut Oil: Makes the cookies moist and brings a hint of tropical taste. You can choose refined coconut oil if you want to avoid the coconut taste.
  • Xanthan Gum: Helps the cookies to stay together without being too crumbly.
  • Vanilla Extract: An essential for most of my baking recipes. It’s a subtle flavor that makes a big difference – you’ll notice if it’s missing.

INSTRUCTIONS FOR MAKING NO-SUGAR PEANUT BUTTER COOKIES

Step 1: Preheat and Prepare:

  • Begin by preheating your oven to 375°F (190°C)
  • Line a cookie sheet with parchment paper. If you don’t have parchment paper, no worries – simply grease your baking sheet.

Step 2: Mix the Dough:

  •  Combine sugar-free peanut butter, egg, and keto-friendly sweetener in a medium mixing bowl.
  • Add coconut oil, stir, then add the rest of the ingredients. Mix thoroughly using a mixer at medium speed. You can use a stand mixer, handheld mixer, or even mix by hand if you prefer.

Step 3: Shape the Cookies:

  • Scoop the dough and roll it into a ball between your palms. Place each ball onto a baking sheet lined with parchment paper, leaving space for the cookies to expand. Shape the dough into small dough balls using an ice cream scooper or cookie scoop and place them on a parchment paper-covered or greased cookie sheet.

Step 4: Add Criss Cross:

  • Grab a fork and make a kiss-cross pattern on top of each cookie. This gives your cookies that classic homemade look and amazing texture.
  • Sprinkle about 1 teaspoon of sugar substitute (set aside in step 2) on the tops of your cookies to give them that touch of sweetness.

Step 5: Bake and Enjoy:

  • Time to bake! Let your cookies bake in the oven for about 7-9 minutes. Keep an eye out – when they’re just starting to turn a nice shade of brown, they’re ready.
  • Once they’re out of the oven, let them cool right on the cookie sheet before transferring them onto a wire cooling rack for complete cooling. Enjoy your delicious low-carb peanut butter cookies!

Tips for the BEST Keto Peanut Butter Cookie Recipe

Get Precise with Measurements: Using measuring cups and spoons ensures you add the correct amounts of each ingredient for the perfect cookies.
Room temperature eggs work best: Let your egg sit out for a bit before using it; it’ll mix in better and make your dough smoother.
Coconut Oil Trick: If your coconut oil is hard, gently warm it up for easy mixing.
Mix, but Not Too Much: Stir until everything’s combined, but don’t go overboard; overly mixed dough can lead to tough cookies.
Cool in the Fridge: If your dough is sticky, pop it in the fridge for 10-15 minutes – it’ll be easier to work with.
Scoop the Same Size: Use a cookie scoop or ice cream scoop to get cookies that are all the same size and bake evenly.
Fork Flattening Made Easy: Dip your fork in a little water or oil to prevent sticking when flattening your cookies.
Watch Closely: Check your cookies a minute or two before the minimum time – they should be lightly golden around the edges.
Cool on the Sheet First: Let your cookies cool on the baking sheet before transferring them; it helps them not break apart. The texture of keto cookies is more delicate than regular cookies.

  1. Love love love this recipe! Have made many batches and eaten way too many of them in one sitting.

    You never let me down, Kasey! Thank you!

    For others making these: I pull them out JUST before they start really changing color. Probably a minute before Kasey would take them out. They’re not as dry and crumbly that way but still set up when cooled.

  2. 4 stars
    These cookies are so easy to make! They are a little dry but overall, I really enjoy the taste! Thank you so much for sharing this easy cookie recipe! It definitely helps when I have a sweet tooth!

  3. 5 stars
    Taste good but had to freeze as they crumbled alot. I used peanut butter with nuts as I did not have creamy peanut butter. Could that be why they fall apart/

    1. I swap regular serve and brown sugar swerve all the time with little to no issue. Definitely done it with these cookies and they’re still mighty tasty! 🙂
