Ingredients

  • 1 cup peanut butter (creamy or crunchy)
  • 1 cup sugar (see note)
  • 1 large egg

Instructions

  • Preheat oven to 350°F. Line a cookie sheet with parchment paper or silicone baking mats.
  • Stir together all three ingredients in a large bowl with a wooden spoon or spatula until smooth.
  • Scoop desired size dough balls onto cookie sheet. Press flat with the back of a fork. The dough is sticky, so either dip your fork in sugar or lightly wet it so the dough doesn't stick.
  • Bake 2 tablespoon size cookies for about 10-14 minutes (1 tablespoon size cookies 8-10 minutes), or until golden brown on the edges and no longer glossy in the center. Let them cool completely on the cookie sheet before removing.
  • Makes 12 (2-Tbsp) cookies or 24 (1-Tbsp) cookies. Store in an airtight container for up to 4 days or freeze for up to one month.
