I know not all of these spices are pantry staples (and can be quite expensive). You can either omit them completely for more simple brown sugar cookies or replace all of the spices with 1/2 tablespoon of a chai tea bag or a pre-made chai spice mix. Or, if you do not have all of the chai spices, just use the spices you do have! Nutmeg, allspice, cloves and a pinch of black pepper would be a great compromise.
