# Method steps:
01 - Preheat oven to 350°F. Line a baking sheet with parchment paper.
02 - In a medium mixing bowl, stir together peanut butter, sugar, and egg until the mixture is smooth and well blended.
03 - Scoop tablespoon-sized portions of dough and roll into balls. Arrange them on the baking sheet spacing about 2 inches apart.
04 - Gently flatten each dough ball with a fork, making a crisscross design on top.
05 - Bake for 9 to 11 minutes, or until edges are set and tops start to crack.
06 - Remove from oven and let cool on the baking sheet for 5 minutes. Transfer to a wire rack to cool completely.
