Preheat your oven to 350 F/ 180 C and line a baking sheet with parchment paper. Add the peanut butter to a bowl and microwave for 20-40 seconds until slightly softened. You don’t want it too warm, or else it will cook the egg.
Step 2
Add the erythritol, egg, almond flour, and vanilla extract to the bowl. Whisk until a dough forms. Cover with plastic wrap and freeze for 15 minutes.
Step 3
Take the bowl out of the freezer and scoop the cookie dough into 12 small balls. Place on the baking sheet and press to flatten slightly. Using a fork, make a crisscross pattern.
Step 4
Bake for 10-12 minutes until slightly golden. Take the baking sheet out of the oven and let the cookies cool for 10 minutes. Serve immediately or store in an airtight container.
