Preheat your oven to 350°F (175°C) and prepare a baking sheet with parchment paper.

In a stand mixer, combine peanut butter and softened butter until creamy. Add sugars, mixing until fluffy. Incorporate egg and vanilla extract.

In another bowl, whisk together flour, baking soda, and salt. Gradually add to wet ingredients, mixing on low until combined.

Roll dough into 1-inch balls and place on baking sheet, spacing them about 2 inches apart. Press with a fork for a crisscross pattern and top with sugar.

Bake for approximately 10 minutes until the edges are lightly golden. Do not overbake to keep centers soft.

Allow cookies to cool on the baking sheet for about 10 minutes, then transfer to a wire rack to cool completely.
