Preheat the oven to 350°F. Line two baking sheets with parchment paper and set them aside.
Whisk the flour, cornstarch, baking powder, baking soda, and salt in a medium bowl.
In a large bowl with an electric mixer, beat the butter and cookie butter until smooth and incorporated. Add the sugars and beat until the mixture is light and fluffy.
Mix in the egg and vanilla extract just until combined.
Pour the dry ingredients into the butter-sugar mixture and mix only until combined. Fold in the cookie pieces.
Scoop the cookie dough onto the prepared sheet trays using a medium cookie scoop, leaving about 1½ inches between the dough balls. Bake the cookies for 9-11 minutes until the edges are set.
Allow the cookies to cool on the sheet pan for a few minutes before transferring them to a wire rack to cool them completely.
