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

In a medium bowl, whisk together the flour, baking soda, and salt until well combined.

Use an electric mixer to cream the unsalted butter, granulated sugar, and light brown sugar until light and fluffy, about 2-3 minutes.

Beat in the eggs and vanilla extract until just combined.

Gradually add the dry mixture to the wet ingredients, stirring gently until blended.

Fold in the semisweet chocolate chips until evenly distributed.

Drop approximately 2 tablespoons of dough onto the prepared baking sheet, leaving 3-4 inches between each scoop.

Optionally, press additional chocolate pieces or sprinkles onto the top of each cookie.

Bake in the preheated oven for 9-11 minutes, or until edges are golden brown.

Immediately cut cookies into heart shapes while warm using a heart-shaped cookie cutter.

Allow cookies to cool on the baking sheet for 5-7 minutes before transferring to a wire rack.

Once cooled completely, arrange cookies on a plate for sharing or store in an airtight container.
