In a medium bowl, whisk together flour, baking powder, baking soda and salt; set aside.
In the bowl of a stand mixer, combine butter, sugar, ginger, cinnamon, cloves and nutmeg; process on speed 4 until well mixed.
Stir in molasses and egg.
Reducing the speed to low and add the dry ingredients; mix until it resembles “Play-Doh” and the dough is pliable.
Separate the dough into two disks and wrap them in double cling film; chill overnight.
Preheat oven to 350ºF.
Take out one disk of dough and leave the other in the fridge until needed.
Flour the work surface and place a sheet of parchment or wax paper over the dough. Roll it out to ¼ inch thickness.
Cut into desired shapes with cookie cutters - if sticky, add more flour. Use a pastry brush to get all excess flour off the cookies (this step makes them prettier and tastier).
Place shaped cookies on cookie sheets, leaving about 1-inch in between.
Transfer to the preheated oven and bake for 8-10 minutes until firm, turning the baking sheets halfway through cooking.
Remove from the heat and let them sit for 5 minutes on the cookie sheets before transferring to a wire rack.
Frost or decorate them when completely cool (*see footnote #2).
