Make easy, gluten-free peanut butter cookies with just three pantry staples: peanut butter, sugar, and egg. These cookies are quick to prepare and have a classic fork-marked texture.

Ingredients

Scale
  • 1 cup peanut butter
  • 1 cup granulated sugar
  • 1 large egg

Instructions

  1. Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper.
  2. In a medium bowl, combine the peanut butter, sugar, and egg. Mix until just combined. Do not overmix.
  3. Roll the dough into 1-inch balls and place them on the prepared baking sheet, about 2 inches apart.
  4. Use a fork to gently press down on each cookie, creating a crisscross pattern. This helps them spread and gives them their signature look.
  5. Bake for 10-12 minutes, or until the edges are lightly golden brown. The centers will still look soft.
  6. Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.

Notes

  • For best results, use creamy, regular peanut butter. Natural peanut butter, which is oilier, may cause the cookies to spread more.
  • If you want to make a smaller batch, you can halve the recipe.
  • Store cookies in an airtight container at room temperature for up to 3 days.
  • You can freeze baked cookies for up to 3 months. Thaw at room temperature.
