Preheat your oven to 350°F (175°C).

Cream together the softened unsalted butter and sugar until light and fluffy.

Add in the egg and vanilla extract, mixing until combined.

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

Gradually blend the dry ingredients into the wet mixture until a smooth dough forms.

Fold in the chopped dates, ensuring they are evenly distributed throughout the dough.

Drop rounded tablespoons of cookie dough onto a baking sheet lined with parchment paper.

Bake in the preheated oven for 8-10 minutes or until the edges are lightly golden.

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