Preheat oven to 350°F (175°C) degrees, making sure the cooking racks are placed in the center of the oven.
Put parchment paper on a large cookie sheet and set aside. Taking out a medium-sized bowl, combine the dry ingredients (flour, baking soda, baking powder, ground coffee, and the salt), and then set the mixture aside.
In a large bowl, cream the softened butter and the white & brown sugars together until fluffy. Beat in each egg one at a time, and then add the vanilla.
Slowly add spoonfuls of your dry ingredients' mixture to the dough, beating well after each addition (10 to 15 seconds).
Finally, lightly mix in the chocolate chips and cacao nibs. The chocolate chips may sink to the bottom if you use an electric mixer, so scoop your dough from the bottom as you form large tablespoons and drop them onto the parchment-covered sheet.
Bake each sheet for 12 minutes, or until edges just start to brown. Don't bake the cookies for more than 14 minutes, or the bottoms may begin to burn.
Remove the cookies from the sheet immediately after taking them out of the over, transferring them to a cooling rack for at least 10 minutes before consuming.
