In a small bowl, mix cream cheese, powdered sugar, and vanilla extract until smooth. Scoop small dollops onto a parchment-lined baking sheet and freeze for at least 1 hour to set.
In a large bowl, beat softened butter, brown sugar, and granulated sugar until light and fluffy.
In another bowl, whisk together flour, baking soda, and salt thoroughly to ensure even distribution in your cookie dough.
Gradually add dry ingredients to wet ingredients, stirring until just combined. Then fold in chocolate chips and Reese’s Pieces.
Take 2 tablespoons of cookie dough, flatten it slightly, then place a frozen cheesecake filling piece in the center before covering it with more dough. Seal the edges well.
Place cookie dough balls on a parchment-lined baking sheet and bake at 350°F (175°C) for 12-14 minutes until edges are golden but centers remain soft. Let cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack; drizzle with melted chocolate if desired.
