Preheat the oven to 350 degrees. Line a baking sheet with parchment paper and set aside.

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

In a large bowl, use an electric mixer to cream the butter, granulated sugar, and brown sugar together until light and fluffy, about 1-2 minutes. Mix in the eggs and vanilla until just combined.

Gradually add in dry ingredients. Mix just until no streaks of flour remain. Fold in chocolate chips.

Scoop about 2 tablespoons of dough onto the baking sheet, spacing them 2-3 inches apart. If desired, press chocolate chunks and sprinkles into the tops of each cookie.

Bake for about 9-11 minutes until edges are slightly golden and centers are underdone. Remove from oven and use a heart-shaped cookie cutter to cut cookies into hearts. Cool on the sheet for 5-7 minutes, then transfer to a wire rack to cool completely.
