Preheat your oven to 350°F (175°C).
In a large mixing bowl, cream together the softened butter, granulated sugar, brown sugar, and Biscoff spread until smooth and fluffy.
Beat in the eggs, one at a time, ensuring each is fully incorporated before adding the next.
In a separate bowl, whisk together the flour, baking soda, and salt.
Gradually add the dry ingredients to the wet mixture, mixing until just combined.
Fold in the chocolate chips gently with a spatula, ensuring they're evenly distributed throughout the dough.
Cover the dough and let it chill in the refrigerator for at least 30 minutes.
Scoop tablespoon-sized portions of dough onto a parchment-lined baking sheet, spacing them about 2 inches apart.
Bake in the preheated oven for 10-12 minutes, or until the edges are golden brown, but the centers are still soft.
Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
