Preheat your oven to 350°F (175°C) and line your baking sheet with parchment paper.
In a large mixing bowl, combine the softened unsalted butter, creamy peanut butter, granulated sugar, and light brown sugar. Beat on medium speed until light and fluffy.
Add the large egg and teaspoon of vanilla extract to the creamed mixture. Beat until well combined.
In a separate bowl, whisk together the all-purpose flour, baking soda, and a pinch of salt. Gradually add this to the wet ingredients, mixing until just combined.
Using a cookie scoop, portion out the dough onto the prepared baking sheet, leaving space between each cookie for spreading. Roll each ball of dough in granulated sugar.
Bake for about 10-12 minutes or until the edges are lightly golden and the tops have a crinkled appearance.
Allow the cookies to cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely.
