These Keto Peanut Butter Cookies taste super peanut-buttery with a slightly chewy texture. Only 2.04 net carbs per cookie!

Ingredients

  • 3/4 cup (192 grams) natural peanut butter (the kind with just peanuts and salt - no added fat or sugar)
  • 1/2 cup (96 grams) THM Gentle Sweet or the copycat listed below
  • 1 1/2 teaspoons vanilla extract
  • 1/4 teaspoon salt add more if your peanut butter is unsalted
  • 1/2 teaspoon baking soda
  • 1 large egg 50 grams, out of shell, cold

Instructions

  • Preheat the oven to 350 °F (170 °C) and line a baking sheet with a piece of parchment paper. Position the oven rack to the lower third of the oven.
  • In a medium mixing bowl, add all the ingredients. Use an electric mixer on low to combine it. At first, it will be very thin but after about 30 seconds of mixing, it should be firm enough to roll into balls. The dough may or may not feel oily.
  • Divide into twelve 28-gram balls and place about 4" apart on the prepared cookie sheet. Press down slightly with the palm of your hand.
  • Bake immediately (it seems as though letting them sit for a while affects how they bake up). Bake for 12-16 minutes or until they've crackled nicely. Let them cool completely on the baking sheet (where they'll continue to bake). If you don't let them cool on the baking sheet, the bottoms of the cookies likely won't be baked enough.
  • Refrigerate them for a better, chewier texture. They can be refrigerated for up to 1 week or kept at room temperature for up to 3 days.

Notes

  • If you want to make a big batch of the THM Gentle Sweet copycat, see the post for the amounts. If you want to make enough for just this recipe, then you need:
    • 54 grams xylitol
    • 42 grams erythritol
    • 1/4 teaspoon powdered stevia
