Preheat oven to 350
Mix the flour, baking powder, and salt together, set aside.
Cream the butter and sugar together. Add eggs, one at a time, then the espresso powder.
Incorporate the flour mixture, then fold in the chips.
Spoon the dough onto baking sheets lined with parchment paper.
Bake 10-12 minutes.
Baking time varies with thickness of cookie. I make then thick, with the large scoop.
You can add in 3/4 cup walnuts as well.
