Best Peanut Butter Cookies (Keto | Low Carb | Gluten-Free)

This is simply the best peanut butter cookies recipe ever. They melt-in-your-mouth, are insanely to easy to make, and only have 0.4g net carbs per cookie!

Cookie Jar Favorite…

I know everyone has a favorite peanut butter cookie recipe, but this one is the BEST! I have made hundreds of peanut butter cookies, and adjusted my recipe each and every time…until this one.

I love the idea of 3-ingredient peanut butter cookies (peanut butter, egg and sweetener) but every time I made them, they always fell short of perfect (for me!). So, I realized they needed other ingredients to make them better suited to my taste buds.

These delicious cookies come out with the perfect crisp edges and have the ultimate soft texture, that literally make them melt-in-your-mouth. They also are perfectly sweet & salt AND are dead easy to make!

Tips & Tricks…

  1. Room Temperature – These cookies require room temperature ingredients. This is important to result in those perfect cookies. If the egg is the only ingredient that is cold and you want to make this recipe now, simply place it in a bowl of warm water for 3 minutes, to increase its internal temperature before incorporating it to the batter.
  2. Mix up the batter – Make sure to beat the butter, peanut butter, sweetener and egg together, for a good minute or so, to make it really creamy.
  3. Use a cookie scoop– I love my cookie scoops, I have them in all different sizes, as they form the perfect cookies with little effort.
  4. Flatten & Fork ’em – Flatten the cookies with the palm of your hand, then use a fork to make those signature marks and ensure they bake evenly.
  5. Cool Down – Be sure to let them cool down on the baking sheet before tucking in, or they will fall apart.
  6. ENJOY – The most important step of the whole process is to enjoy them! With only 0.4g net carbs per cookie, they are a great cookie to indulge in and go a little nuts for.

Add Something Extra…

  • Chocolate Chips – Fold in 80g (1/2 cup) sugar-free chocolate chips to the batter, before baking them.
  • Cinnamon Spice – Add 5ml (1 tsp) of cinnamon or pumpkin pie spice, to the batter in step 3, to give the cookies some extra depth.
  • CrunchFancy a crunch? Fold in 40g (1/4 cup) chopped peanuts to the batter, before baking them.

Freezer Friendly…

These yummy delights will store beautifully in an air-tight container, at room temperature, for 3-4 days.

Alternatively, before you bake them, you can freeze the dough for up to 2 months. Just remember to take them out of the freezer and thaw them completely, before forming the cookies and baking them.

Lastly, if you make several batches of these gorgeous cookies (I don’t blame you in the slightest), and want to freeze them, just note that if you lay a piece of parchment paper between the cookies, they won’t stick together!
