Calories: 4kcal

192 grams granulated monkfruit sweetener or other granulated sweetener (about 1 cup) adjust to taste
1 tsp vanilla extract (optional)
264 grams peanut butter (about 1 cup) nut-free option: use seed butter or coconut butter with peanut flavoring
1 large egg, room temperature
2 TBS cocoa powder optional — for chocolate version

Preheat the oven to 350°F (175°C). Line a large baking sheet with parchment paper and set aside.
In a large bowl, combine the sweetener, peanut butter, egg, and vanilla (if using). Stir until the mixture forms a smooth, uniform dough. If making the chocolate version, add the cocoa powder and mix until incorporated.
Scoop the dough by tablespoonfuls onto the prepared baking sheet, spacing each about 2 inches apart.
Roll each scoop into a smooth ball, then flatten and shape the cookies to your preferred thickness. Bake for about 12 minutes, or until the edges are lightly golden.
Remove the baking sheet from the oven and let the cookies cool on the pan for about 15 minutes, or until firm. Transfer to a wire rack to cool completely before adding any frosting. Store leftovers in an airtight container in the refrigerator for up to one week.
