Pre-heat your oven to 350° and line a baking sheet with parchment paper.
Add your butter to a large glass bowl and melt in the microwave. (Mine takes about 1 minutes to partially melt and then I stir to fully melt the rest)
Once melted, add in the white and brown sugars, coffee powder, and cocoa powder. Stir with a whisk to combine.
Next, add in the egg, and the vanilla extract and whisk until the egg is fully incorporated.
Sprinkle in the flour, baking powder, and chocolate chips. Use a sturdy spatula to combine just until you no longer see white flour. Do not over-mix.
Use a cookie scoop to place cookies onto the baking sheet. These don't spread much so you only need to place them about 1 and ½ inches apart. (If you don't have a scoop, these are about 2 tablespoons or about the size of a golf ball.)
Once on the baking sheet, you can sprinkle a pinch of the sea salt on each cookie. I also like to add a few extra chocolate chips on top.
Bake for 10-11 minutes then remove from the oven and let cool for about 15 on the baking sheet.
