Preheat the oven to 350°F (175°C) and line a baking sheet with parchment paper.

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

Beat in the eggs one at a time, then stir in the vanilla extract.

In a separate bowl, whisk together the flour, baking soda, and salt.

Gradually add the dry ingredients to the wet ingredients, mixing until just combined.

Using a cookie scoop, take a portion of dough and flatten it in your hand.

Place a spoonful of the filling in the center, then fold the dough over to seal it.

Place the stuffed cookie on the prepared baking sheet.

Repeat with the remaining dough and filling.

Bake in the preheated oven for 10-12 minutes, or until the edges are lightly golden.

Allow to cool on the baking sheet for a few minutes before transferring to a wire rack to cool completely.
