Add eggs, one at a time, mixing for one minute after each addition. Add vanilla.

Reduce mixer to low speed and slowly add flour mixture in 3 additions, alternating with buttermilk in two additions (flour, buttermilk, flour, buttermilk, flour).

8 ounces chopped semisweet chocolate
Use a 2-tablespoon sized (standard) cookie scoop and place on cookie sheet, about 2 inches apart. Bake for 10-12 minutes, or until edges are lightly browned.
Immediately slide parchment onto cooling rack and let cookies cool for 5 minutes. Transfer cookies from parchment directly to cooling rack to cool completely.
I highly recommend using a kitchen scale when you are baking. It truly makes a huge difference using weights instead of scooping, especially when it comes to flour, as it's easy to under or over measure.
Insulated baking sheets are best when making cookies. They help protect the bottom of the cookies from browning too fast. If you don’t have one, you can simply stack two baking pans instead.
We use baking chocolate and chop it ourselves. However, you can certainly use chocolate chips instead.
