How to Make 3-Ingredient Peanut Butter Cookies
- Preheat oven: Preheat to 350°F (175°C) and line a baking sheet with parchment paper or a silicone mat for easy cleanup and perfect cookie bottoms.

- Shape cookies: Gently flatten each mound with a fork in a crisscross pattern, creating classic cookie grooves and ensuring even, tender baking throughout.
- Bake cookies: Bake for 10–12 minutes until edges set and tops show light golden cracks—avoid overbaking to keep centers soft and chewy.
