Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper.
In a bowl, whisk together flour, baking soda, and salt.
In another bowl, cream together softened butter, granulated sugar, brown sugar, and peanut butter until fluffy. Add vanilla extract and mix until well combined.
Gradually add the dry ingredients to the wet mixture until just combined.
Fold in chopped chocolate peanut butter cups evenly into the dough.
Scoop tablespoon-sized balls onto prepared baking sheets and bake for 10-12 minutes until edges are lightly golden. Allow to cool before enjoying.
