In a mixing bowl, cream together softened butter and sugar in a bowl until light and fluffy. (I recommend using a stand mixer with paddle attachment, but you can use a wooden spoon and some elbow grease instead.) Then, add the eggs one at a time, mixing well after each addition.
In another bowl, whisk together the dry ingredients (cocoa, flour, coffee, baking powder and salt.)
Add the dry ingredients to wet ingredients and combine just until the dough comes together.
Fold in dark chocolate chips.
Drop scoops of dough onto parchment lined sheet trays. (I used a small cookie dough scoop.) Use your fingers to smash the cookies down a bit so they flatten out more easily when baking.
Bake for 11-13 minutes. Let cool completely.
Freezer Instructions
Freeze for Later: Scoop or shape the dough, place on a baking sheet to flash freeze, then transfer to an airtight container or freezer bag. Freeze for up to 3 months.Prepare from Frozen: Bake straight from frozen—just add 1–2 minutes to the baking time.
Notes/Tips
Optional Topping: Melt white chocolate chips in the microwave (stirring after each 30-second interval) and scoop into a small plastic bag. Snip off end and drizzle cooled cookies with white chocolate.
