Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper because scrubbing baked-on peanut butter is not a personality trait.
Mix everything in a bowl. Peanut butter, sugar, egg. Stir until smooth and thick. It’ll look like cookie dough’s minimalist cousin.
Scoop the dough into tablespoon-sized balls and place them on the baking sheet, leaving space between each one. They spread a little—like introverts warming up.
Flatten with a fork, making that classic crisscross pattern. It’s not just cute; it helps them bake evenly.
Bake for 10–12 minutes until the edges look set but the centers still look slightly soft. Trust the process.
Cool for 5 minutes on the pan, then move to a rack. They firm up as they cool, so don’t panic-bake them into sadness.
