Before starting, measure and prepare all of your ingredients. This will ensure the process runs smoothly and efficiently.
In a large mixing bowl, combine the flour, cocoa powder, cinnamon, ginger, nutmeg, cloves, baking soda, and salt. Whisk the dry ingredients until fully combined and set the bowl aside.
In a separate bowl, whisk together the egg, molasses, and vanilla extract until smooth and fully combined.
In the bowl of your kitchen mixer, add the room-temperature unsalted butter and granulated sugar. Using the paddle attachment, cream them together on medium speed for about 2-3 minutes, until the mixture becomes light and fluffy.
Scrape the butter mixture from the sides of the bowl using a silicone spatula, then add the egg and maple molasses mixture. Mix on medium speed until fully combined.
Gradually add the dry ingredients to the wet mixture, about ⅓ at a time, mixing on low speed after each addition. Continue mixing until a smooth, slightly firm dough forms. The dough should hold together but not be sticky.
Divide the dough into two equal portions, flatten them into disks, and wrap them in food wrap. Place the dough in the refrigerator to chill for at least 1 hour. This helps firm the dough, making it easier to roll and cut.
