Step 1: Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
Step 2: In a large mixing bowl, combine the creamy peanut butter, 1 cup granulated sugar, and brown sugar. Mix until smooth and creamy.
Step 3: Beat in the eggs one at a time, followed by the vanilla extract, mixing until well combined.
Step 4: In a separate bowl, whisk together the baking soda, salt, and all-purpose flour.
Step 5: Gradually add the dry mixture to the wet ingredients, stirring until just combined. Be careful not to overmix.
Step 6: Using a tablespoon or cookie scoop, portion out the dough and roll it into balls. If desired, roll the balls in additional granulated sugar for added sweetness and texture.
Step 7: Arrange the cookie dough balls on the prepared baking sheet, leaving space between each one.
Step 8: Using a fork, gently press down on each cookie ball to flatten it and create a crisscross pattern on top.
Step 9: Bake in the preheated oven for 10-12 minutes, or until the edges are lightly golden. The centers may look slightly underbaked, but they will firm up as they cool.
Step 10: Allow the cookies to cool on the baking sheet for about 5 minutes before transferring them to a wire rack to cool completely.
