Preheat the oven to 350°F. Prepare a baking sheet by lining it with parchment paper. Set aside.
Combine all ingredients in a bowl, except for the chocolate.
Beat with an electric mixer until well combined.
Scrape the sides of the bowl with a spatula.
Fold in the chocolate chips or chunks.
Using a regular-sized ice cream scoop, scoop out the dough onto the prepared baking sheet. Flatten each cookie. (I made 12 cookies.)
Bake in the preheated oven for 14-20 minutes, rotating the pan halfway through baking. (See notes.)
Allow the cookies to cool completely on the pan before transferring them to a container.
