Then fold in the chocolate chips. Cover and chill in the fridge for 20 minutes. Meanwhile, preheat your oven to 325F and line 2 baking sheets with parchment paper.
1/2 cup chocolate chips
Using a medium cookie scoop or tablespoon, drop rounded cookie dough 2" apart onto the prepared baking sheets. Top each cookie dough with a few more chocolate chips if desired.
Bake for 9-11 minutes or until the edges are lightly browned and the center is almost set. Let cool on the baking sheet for 5-10 minutes before transferring to a cooling rack.
Notes
You can store these cookies in an airtight container at room temperature for 3-4 days.
Substitutions:
Unsalted butter - You can use salted butter and just skip the salt.
Brown sugar - You can use light or dark, or granulated sugar if that's all you have. Brown sugar is preferred because it's more flavorful.
Egg - Can be substituted with a flax egg (mix 1 tablespoon of ground flaxseed with 3 tablespoons of warm water and let the mixture stand for one minute before using) or a baking powder-oil solution (combine 2 tablespoons of water with 1 tablespoon vegetable oil and 2 teaspoons baking powder).
Chocolate chips - Can be substituted with M&M chocolates or chocolate chunks.
