Preheat your oven to 350°F (175°C).

In a bowl, mix together the cookie butter, brown sugar, and granulated sugar until well combined.

Beat in the softened butter, then add the egg and vanilla extract, mixing until smooth.

In a separate bowl, whisk together the flour, baking soda, and salt.

Gradually add the dry ingredients to the wet mixture, stirring until just combined.

Scoop tablespoon-sized balls of dough onto a baking sheet lined with parchment paper, spacing them apart.

Bake for 10-12 minutes until the edges are golden and the centers are chewy.

Let cool on the baking sheet for a few minutes before transferring to a wire rack to cool completely.
