Preparation Steps

• Preheat oven to 375°F (190°C). Line baking sheets with parchment paper.
• In a medium bowl, whisk together flour, baking soda, baking powder, and salt.
• In a large bowl, cream together butter, granulated sugar, and brown sugar until light and fluffy. Beat in peanut butter, egg, and vanilla extract.
• Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Do not overmix.
• Roll dough into 1-inch balls and place on prepared baking sheets. Flatten slightly with a fork, making a crosshatch pattern.
• Bake for 8-10 minutes, or until edges are lightly golden. Let cool on baking sheets for a few minutes before transferring to a wire rack to cool completely.
