- Preheat your oven to 350°F (175°C) and line an 8x11 inch baking pan with parchment paper.
- In a large mixing bowl, beat together 1 cup of softened butter and 1 cup of packed brown sugar until light and fluffy.
- Add in 1 egg, 1 cup of peanut butter, and 1 teaspoon of vanilla, mixing until fully combined.
- Gradually incorporate 2 cups of all-purpose flour and fold in 1 cup of chocolate chips.
- Press two-thirds of the cookie dough into the bottom of the prepared baking pan.
- Sprinkle 1 cup of chopped peanut butter cups over the cookie layer.
- Spread marshmallow fluff over the peanut butter cups to form a creamy layer.
- Top with remaining dough, pressing it down gently for even coverage.
- Bake for about 25 minutes until golden brown. Allow to cool for 1 hour.
- Lift the bars out of the pan and cool completely before slicing into squares.

Notes
Store leftovers in an airtight container; refrigeration extends freshness but may alter texture. Chill before slicing for cleaner cuts.
