Measure and prepare all of your ingredients before starting. This ensures an organized and smooth baking process.I’m making a double portion here, so feel free to adjust if you’re making a smaller batch.
In a glass mixing bowl, whisk together the flour, cinnamon, ginger, baking soda, cloves, nutmeg, and salt until fully combined. Set this bowl aside.
In a medium-sized bowl, whisk together the egg, molasses, and vanilla extract until smooth and well combined. Set aside.
In the bowl of your kitchen mixer, add the room-temperature unsalted butter and packed brown sugar. Using the paddle attachment, cream them together on medium speed for about 2-3 minutes, until the mixture becomes light and fluffy.
Scrape down the sides of the bowl with a spatula, then add the wet ingredients (egg, molasses, and vanilla mixture) to the creamed butter and sugar. Mix on medium speed until fully combined and smooth.
Gradually add the dry ingredients to the wet mixture, about 1/3 at a time, mixing on low speed after each addition. Continue mixing until a smooth dough forms. The dough should hold together but not be sticky.
Divide the dough into two portions, flatten each into a disk, and wrap in food wrap.
Place the dough in the refrigerator to chill for at least 1 hour. For longer storage, you can freeze the dough for up to 3 months. Just thaw in the refrigerator overnight before using.
