Preheat oven to 350 degrees. Line two large cookie sheets with parchment or Silpat liners. Set aside.
In a large bowl, mix the flour, baking powder, cinnamon, cloves and salt together and set aside. In the bowl of a stand mixer, cream the butter and sugar until light in color, fluffy and airy, about 3 minutes. Add the eggs, one at a time, mixing until fully incorporated and then add the vanilla.
Slowly add the dry ingredients and mix just until combined, and until no white streaks remain. Stir in the coffee grounds and mixed until fully distributed throughout the dough. Place the dough, in 1-inch balls, about 2-inches apart on the cookie sheets.
Bake for 12-14 minutes until lightly browned on the edges but soft in the middle. Cook for a few minutes on the cookie sheet, and then cool completely on a wire rack.
