Instructions

Preheat Oven. Preheat your oven to 350 degrees Fahrenheit to ensure it’s at the perfect temperature for baking the cookies evenly.
Mix Ingredients. In a large mixing bowl, combine the peanut butter, egg, and brown sugar (or brown sugar substitute for keto) and whisk until well blended into a smooth dough.
Shape Dough. Scoop tablespoon-sized portions of dough and roll each into a ball using your hands to keep the size consistent.
Place on Baking Sheet. Arrange the dough balls spaced about 2 inches apart on a parchment-lined baking sheet to allow room for spreading.
Flatten and Pattern. Using the back of a fork, gently press down on each ball in a crisscross pattern to flatten them and give that classic peanut butter cookie look.
Bake. Bake the cookies for 8 minutes at 350 degrees. This short baking time helps retain a chewy texture.
Cool and Store. Remove cookies from oven and let them cool completely on a wire rack before transferring to an airtight container for storage.

Notes

Nutrition values provided cover the entire recipe, not split by version.
For softer dough issues, pack brown sugar firmly or consider increasing sugar quantity (up to 1 cup) to absorb extra moisture.
Using granulated sugar instead of brown sugar can help create a thicker dough.
Chilling the peanut butter before mixing may make the dough easier to handle by thickening it.
The choice of peanut butter brand affects dough consistency due to oil content.
Use a large egg as smaller eggs may cause softer dough.
