In a large bowl, mix the flour, cinnamon, baking powder, ginger, allspice, cardamom, cloves, baking soda, salt and pepper. Set aside.
With a mixer on medium high, beat the butter, granulated sugar and brown sugar until the mixture looks light and fluffy. Add the eggs, egg white, corn syrup and vanilla. Switch to medium speed and beat until everything is combined.
Turn the mixer to low and add the flour mixture a little at a time until a dough forms. Wrap the dough in plastic wrap and refrigerate for at least 1 hour or overnight.
Heat the oven to 375°F and line baking sheets with parchment paper. Unwrap the dough and drop it by 2-teaspoon portions onto the sheets, leaving about an inch between each.
Bake for 7 to 8 minutes, or until the edges look golden. Let the cookies cool on the sheet for 5 minutes, then move them to a rack to cool completely.
