Great Tools for the Best Keto Peanut Butter Cookies

• Low Carb Granulated Sweetener: my go-to low carb, keto “sugar”. Great for baking, but not a 1:1 sub for sugar in any regular recipe. Trust me. 😉 This is the key ingredient to making the very best keto pb cookies.
• Medium Cookie Scoop: my #1 recommended & reader-purchased cookie scoop. For 10+ years, I used all sorts of cookie scoops that failed (even the name brands we all know), these are the absolute best. They’re so sturdy, used for 100s and 100s of batches of scooping firm and sometimes frozen cookie dough and they last through it all. My recommendation: buy more than one. You won’t regret it.
• Rose Gold Chef Cookie Sheet & Parchment Paper Sheets: I’ve been on the hunt for high-quality cookie sheets since 2012, when I used dollar store cookie sheets that warped, $10-12 big brand cookie sheets that also warped and everything else in between. This cookie sheet is not only beautiful, but functional, durable and does not warp one bit. It ensures even heating & baking throughout the sheet. Bonus: I found pre-cut parchment sheets that actually fit this cookie sheet!

Description

Keto Peanut Butter Cookies: this low carb peanut butter cookies recipe is made with only 4 ingredients. The best peanut butter keto cookies—only 2 net carbs and keto-friendly.

---

Ingredients

Scale 1x2x3x

• 1 cup unsalted, creamy natural peanut butter
• 1 flax egg (1 tablespoon golden ground flaxseed + 3 tablespoons water, whisked together, set for 15 minutes)
• ½ cup low carb granulated sweetener
• ¾ teaspoon baking soda
• ½ teaspoon pure vanilla extract (optional)
• ¼ teaspoon salt (optional)

---

Instructions

1. Preheat oven to 350°F. Line a baking sheet with parchment paper or greased foil. Set aside.
2. In a medium bowl, add all ingredients. Using a rubber spatula, fold until very thoroughly mixed. This batter is very thick—if you prefer, use a stand mixer or hand mixer to whisk together ingredients.
3. Using a medium scoop, scoop and drop cookie dough balls onto the prepared baking sheet, spaced evenly apart. Using a fork, press down on cookie to flatten. Repeat in the opposite direction, creating crisscross marks. Make sure to leave space between cookies, as they will spread while baking.
4. Bake for 10-14 minutes. Mine took 12 minutes. Transfer cookie sheet to cooling rack and allow to cool for 20 minutes—do not remove from sheet for 20 minutes, as cookies are a bit soft. Then, if desired, transfer cookies directly onto the cooling rack to cool until completely cooled. Enjoy! Storing notes below.
