Instructions

  • Mix the dough. In a bowl, combine 1 cup (270 g) creamy peanut butter, 1 cup (200 g) brown sugar, and 1 (50 g) large egg. Stir with a spoon until thoroughly mixed and no streaks remain.
  • Chill the dough. Cover the bowl and refrigerate for 30 minutes. Don't skip this step or the cookies will spread too much.
  • Preheat and prepare. Preheat oven to 350°F (175°C). Line a baking sheet with parchment paper.
  • Shape the cookies. Divide dough into 8 equal portions and roll into balls. Place on prepared baking sheet with at least 2 inches between each cookie.
  • Make crosshatch pattern. Dip a fork in sugar, then gently press down on each dough ball to make a crosshatch pattern. Press just enough to flatten to about 1/2-inch thick.
  • Bake. Bake at 350℉ for 10-12 minutes, until edges are set and tops no longer look glossy. Don't overbake.
  • Cool completely. Let cookies sit on the baking sheet for at least 10 minutes before moving to a cooling rack. They're fragile when hot and will fall apart if moved too soon.

Notes

  • Peanut Butter: Use regular creamy peanut butter like Skippy or Jif, not natural peanut butter. Natural peanut butter will make the cookies spread too much.
  • Don't Overbake: Take cookies out when edges are set and tops no longer look glossy, even if centers seem slightly underdone. They firm up as they cool.
  • Storage: Store in an airtight container at room temperature for up to 1 week.
