Wait to preheat the oven until the cookies are done chilling. Line two large baking sheets with parchment paper or silicone baking mats and set aside. If you don't plan to chill the cookies (not recommended, but I get that sometimes you can't wait), preheat the oven to 350 F/175 C at this point.
Add 1/2 cup (1 stick) room temperature butter, 2/3 cup packed light brown sugar, and 1/4 cup granulated sugar into a large bowl. Beat on a medium speed for about 30 seconds until the mixture is smooth and no lumps remain (we don't need to cream the mixture as much as we do when making cakes). If you notice any stubborn brown sugar chunks, use the back of a fork to break them up.
Mix in 1 large egg, 2 tsp vanilla extract, and 1 tsp honey (gives the cookies a softer texture and helps create golden brown edges! Learned this trick from Scientifically Sweet) on a medium speed until incorporated. Scrape around the sides and bottom of the bowl with a rubber spatula as needed. Then add 1 2/3 cups flour (make sure it's properly measured by using a scale or fluff the flour in the bag, then spoon it into your measuring cup), 1/2 tsp baking soda, and 3/4 tsp fine salt, and mix on a low speed until no visible streaks of flour remain. Scrape the sides and bottom of the bowl with a rubber spatula (hidden pockets of butter will cause the cookies to overspread!). Fold in 1 cup of chocolate chips or chunks of your choice (I prefer half milk/half dark chocolate chips).
Use a measuring spoon or cookie scoop to shape 3 Tbsp cookie dough balls. You should end up with 13 cookie dough balls. These cookies can be baked without being chilled (skip to the next step if you must), but they turn out best when they're chilled. They're thicker, chewier, more flavorful, and just all around better! If you're able to chill them, place them close together on one of the prepared pans and chill them uncovered in the fridge for 1-2 hours. If you plan to chill them overnight or longer (they can be chilled in the fridge for up to 3 days), store them in an airtight container. Note: You get bonus points if you chill them overnight!!
While the cookies chill/about 20 minutes before you plan to bake the cookies, preheat the oven to 350°F/175°C. Space the cookies 2-3 inches apart on the prepared baking sheets. They need some space because they will spread a bit while they bake!
Bake the cookies one tray at a time for 12-13 minutes (the sweet spot in my oven is 12.5 minutes, but every oven bakes differently), and rotate the pan halfway through to help them bake evenly. The cookies are ready when the edges just start to brown, but the centers still look puffy and slightly under-baked. The cookies will continue to bake on the sheet and firm up once removed from the oven, so it's always best to err on the side of under-baked!
Place the cookie sheet on a wire rack and let the cookies cool fully on the pan. I like to press a few extra chocolate chips on top of each cookie while they're still warm and add a garnish of flaky sea salt.
Enjoy warm with a glass of milk, or store fully cooled cookies in an airtight container at room temperature for up to 3 days.
