Start by preheating the oven to 350 degrees Fahrenheit and line 2 cookie sheets with parchment paper.
Then in a small bowl add chocolate chips and butter. Place in the microwave for 30 seconds. Remove and mix. Then place back into the microwave for 30 more seconds if not fully melted. Remove, mix and set aside for later.
In another bowl add coconut sugar and 1 room temperature egg. With a whisk beat the two together for 3 minutes until thick and light in color.
Pour the slightly cooled chocolate into the sugar and egg mixture and stir until just combined.
Add the flour, protein powder, salt and freshly ground coffee (if using) to the batter. Gently fold the ingredients into each other until just combined. Stop Mixing the moment the last bit of flour disappears.
With a small to medium cookie scoop, scoop 6-8 brownie cookies onto a cookie sheet lined with parchment. Evenly space for even baking.
Bake the cookies for 8-10 minutes at 350 F. Be careful not to over bake. The cookies are done when the tops are shiny and centers are slightly underbaked.
Let the cookies cool and enjoy!
