Preheat your oven to 180°C (350°F) and line a baking sheet with parchment paper.
In a medium-sized mixing bowl, whisk together the flour, baking soda, and salt. Set this dry mixture aside.
In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until it becomes light and fluffy. You can use a hand mixer or do this by hand with a wooden spoon.
Add the egg and vanilla extract to the butter-sugar mixture and mix until well combined.
Gradually add the dry mixture (flour, baking soda, and salt) to the wet mixture (butter, sugars, egg, and vanilla), mixing until a dough forms.
Stir in the chocolate chips until they are evenly distributed throughout the dough.
Using a spoon or cookie scoop, drop rounded tablespoons of dough onto the prepared baking sheet, spacing them about 5 centimeters (2 inches) apart.
Bake in the preheated oven for about 12 minutes or until the edges of the cookies are golden brown, but the centers are still soft.
Remove the cookies from the oven and let them cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely.
Enjoy your delicious homemade chocolate chip cookies!These measurements should help you make approximately 24 cookies. Adjust the baking time if you prefer your cookies more or less crispy, and feel free to customize with nuts or other mix-ins if you like.
