Start by melting the butter in your medium mixing bowl in the microwave for about 30 seconds, until just softened and fragrant.
Add the light brown sugar to the melted butter and stir with the spatula until the mixture is glossy and the sugar begins to dissolve, creating a caramel color.
Stir in the vanilla extract, letting its warm aroma brighten the mixture as you combine it thoroughly.
Next, sift in the all-purpose flour and fold it into the wet ingredients until the dough comes together and no dry streaks remain. It will be thick and slightly crumbly but cohesive.
Gently fold in the semi-sweet chocolate chips, distributing them evenly throughout the dough. It will look studded and inviting.
Using a tablespoon or small cookie scoop, portion out the dough onto your prepared parchment-lined baking sheet, shaping each into a small round or flattening gently with your fingers.
Sprinkle a tiny pinch of sea salt flakes on top of each bite for that perfect sweet-salty contrast.
Place the baking sheet in the fridge and chill for at least 30 minutes to firm up the bites and allow the flavors to meld.
Once chilled, they are ready to serve—soft, chewy, and packed with nostalgic cookie dough flavor. Keep leftovers in an airtight container in the fridge for up to 5 days.
