Preheat the oven to 350°F (175°C).
In a medium bowl, whisk together the flour, baking soda, and salt.
In a large bowl, cream together the softened butter, brown sugar, and granulated sugar until light and fluffy.
Beat in the eggs one at a time, then stir in the vanilla.
Gradually blend in the dry ingredients until just combined.
Fold in the chocolate chips gently.
Chill the dough in the refrigerator for at least 30 minutes.
Roll out the chilled dough and cut into heart shapes.
Place the cookies on a baking sheet lined with parchment paper.
Bake for 10-12 minutes or until the edges are golden brown.
Allow cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack.
