Preheat your oven to 350°F. Line a baking sheet with parchment paper.

In a medium bowl, whisk together the flour, baking soda, and salt. Set aside.

In a large mixing bowl, cream together the softened butter, granulated sugar, brown sugar, and vanilla extract until smooth and fluffy.

Add the eggs one at a time, mixing well after each addition.

Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Fold in the chocolate chips.

In a separate bowl, prepare the cheesecake filling by mixing the softened cream cheese, granulated sugar, vanilla extract, and egg yolk until smooth and creamy.

To assemble the cookies, take a tablespoon of cookie dough and flatten it in your hand. Place a teaspoon of cheesecake filling in the center, then wrap the cookie dough around the filling, sealing it completely. Roll into a ball and place on the prepared baking sheet.

Repeat with the remaining dough and filling.

Bake for 10-12 minutes, or until the edges are golden brown.

Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
