Ingredient Notes
Peanut Flour: My *secret* ingredient.
Peanut flour is PACKED with protein, as it’s made from partially defatted peanuts — essentially, peanuts are ground into a paste, then pressed to extract the oil — the end result is a keto flour with significantly less fat and more protein than most flour alternatives.
Each peanut flour is processed differently, I’ve only tested this recipe with Protein Plus.
BONUS: peanut flour makes baked goods extra fluffy!

Brown Swerve/Lakanto: Both of these keto sweeteners are made from erythritol, which doesn’t spike blood sugar levels and is a fave in the low carb community. Either of these brands can be used as a 1:1 swap with traditional sugar, so if you’re using a different brand of erythritol, you may want to increase the amount you add.
Peanut Butter: Be sure to grab a jar of no sugar added peanut butter.
Recipe Variations
These PB cookies are addictingly delicious on their own!! But if you’d like to mix things up a tad, here are some options:
- Add chocolate. Try mixing in sugar free chocolate chips, or dipping your baked/cooled cookies into melted keto chocolate.
- Add chopped keto nuts or unsweetened shredded coconut to the batter.

Lindsey's Tips
- Lakanto, Swerve, or Erythritol. I stick to Lakanto and Swerve which are a 1:1 swap with traditional sugar. If using a different brand of Erythritol, keep in mind it's 70% as sweet as sugar, so you may need to add more to taste.
- Peanut Butter often contains added sugar. Read labels carefully before purchasing -- I love Justin's or Trader Joe's brand.
- Peanut flour should only contain defatted peanuts and salt and is different than peanut butter powder (which is often sweetened with sugar). Each brand defats the peanuts in varying amounts, I prefer Protein Plus Peanut Flour!
- Nutritional information is for 1 cookie if you make 18 cookies using this recipe. Each contains .75g erythritol, which makes the NET carb count about 3g per cookie:
