In a mixing bowl, combine the softened butter, brown sugar, and vanilla extract. Use a spatula to mix until the mixture is smooth and creamy, with a fragrant aroma of butter and vanilla filling the air.
Add the all-purpose flour and sea salt to the bowl. Stir thoroughly until the dough comes together, feeling slightly tacky but manageable, with no dry flour visible.
Gently fold in the chocolate chips, distributing them evenly throughout the dough. This step creates little pockets of melty chocolate that make each bite irresistible.
Using a tablespoon or small scoop, portion out the dough into bite-sized balls. Roll each between your palms to form smooth, round bites, feeling their slightly sticky texture.
Place the shaped bites onto a parchment-lined baking sheet, spacing them about an inch apart. Flatten each slightly if you prefer a more uniform shape.
Chill the tray in the refrigerator for at least 30 minutes. This helps the fats firm up, making the bites hold their shape and intensify the flavors.
Once chilled, remove the bites from the fridge. Optional: sprinkle a tiny pinch of sea salt on top of each for a flavor contrast that enhances sweetness.
Serve the cookie dough bites straight from the fridge for a firm, chewy texture, or let them sit at room temperature for 10 minutes for a softer, gooey experience.
