Line a baking sheet with parchment paper.
In a bowl, whisk together the flour, cinnamon, ginger, cardamom, baking soda, and salt.
In a stand mixer fitted with the paddle attachment, cream together the butter, sugar, and molasses on medium speed until light and fluffy, about 2 minutes. Scrape down the sides of the bowl with a rubber spatula. Mix in the eggs, one at a time, until well incorporated, scraping down the bowl with a rubber spatula as needed. Mix in the fresh ginger and black pepper. Add the flour mixture all at once and mix on low speed just until it all comes together.
Scoop the cookie dough using a #40 (1 1/2-tablespoon) portion scoop, roll the dough balls in sparkling sugar, place onto the prepared baking sheet, leaving about 1 1/2 inches of space between them to spread and flatten the balls slightly. Refrigerate the cookie dough balls for at least 30 minutes. The dough can also be made the day before or frozen for a few weeks. You can make the cook- ies larger or smaller, but it will affect the baking time.
Preheat the oven to 375°F / 190°C.
Bake, one sheet at a time, in the middle of the oven for 10 to 12 minutes, until the cookies are puffed, look slightly dry, and are golden brown just on the bottom. Don’t overbake or they lose their soft texture.
Cool completely on the baking sheets.
