📖 Instructions

1. Prepare the Dry Ingredients: In a large bowl, whisk together 3 cups of all-purpose flour, 1 tablespoon of ground ginger, 1 teaspoon of ground cinnamon, 1/2 teaspoon of ground cloves, 1/2 teaspoon of ground nutmeg, 1/2 teaspoon of baking soda, and 1/4 teaspoon of salt. Make sure everything is well combined and there are no clumps of spice. Set this aside.
2. Cream Butter and Sugar: In the bowl of a stand mixer fitted with the paddle attachment (or using a hand mixer), cream together 1/2 cup (1 stick or 113g) unsalted butter, softened to room temperature, and 1/2 cup (100g) packed light brown sugar. Beat on medium speed until the mixture is light and fluffy, about 2-3 minutes. Scrape down the sides of the bowl as needed.
3. Add Egg and Molasses: Beat in 1 large egg until fully incorporated. Then, add 1/2 cup (120ml) unsulphured molasses (not blackstrap molasses, it's too strong!) and 1 teaspoon of vanilla extract. Mix on low speed until everything is just combined. The mixture might look a little curdled at this point, but don't worry, it'll come together.
4. Combine Wet and Dry Ingredients: Gradually add the dry ingredient mixture to the wet ingredients, mixing on low speed until just combined. Be careful not to overmix! The dough will be thick and may seem a little crumbly, but it should hold together when pressed.
5. Chill the Dough: Divide the dough into two equal portions. Flatten each portion into a disk, wrap tightly in plastic wrap, and refrigerate for at least 2 hours, or preferably overnight. Chilling is crucial for easy rolling and to prevent the cookies from spreading too much during baking.
6. Preheat Oven and Prepare Baking Sheets: When you're ready to bake, preheat your oven to 350°F (175°C). Line several baking sheets with parchment paper or silicone baking mats.
7. Roll Out the Dough: Take one chilled dough disk out of the refrigerator. On a lightly floured surface, roll the dough to about 1/4-inch thickness. If the dough is too cold and hard to roll, let it sit at room temperature for 5-10 minutes. If it gets too sticky while rolling, dust lightly with more flour.
8. Cut Out Cookies: Use your favorite cookie cutters (gingerbread men, stars, trees, etc.) to cut out shapes. Carefully transfer the cut-out cookies to the prepared baking sheets, leaving about 1 inch between them. Gather any dough scraps, gently press them together, re-wrap, and chill again briefly before re-rolling. Do not overwork the scraps.
9. Bake the Cookies: Bake for 8-12 minutes, depending on the size and thickness of your cookies. Smaller, thinner cookies will bake faster. The cookies are done when the edges are lightly set and the centers still look a tiny bit soft. They will firm up as they cool. For chewier cookies, bake for less time; for crispier cookies, bake a minute or two longer.
10. Cool: Let the cookies cool on the baking sheets for 5 minutes before carefully transferring them to a wire rack to cool completely. They must be completely cool before icing.
11. Prepare Royal Icing: In a medium bowl, combine 3 cups (360g) powdered sugar, 2 tablespoons (30ml) meringue powder, and 4-6 tablespoons (60-90ml) warm water. Beat on medium-high speed with an electric mixer until very stiff peaks form, about 5-7 minutes. This is your stiff icing.
12. Thin Icing for Flooding (Optional): If you want to "flood" cookies (fill in areas with smooth icing), take a portion of the stiff icing and add water a tiny bit at a time (1/4 teaspoon at a time), mixing until it reaches a consistency where a ribbon of icing dropped from a spoon disappears back into the icing within 10-15 seconds. This is often called 10-second icing.
13. Color the Icing: Divide the icing into separate small bowls for different colors. Use gel food coloring for vibrant hues without adding too much liquid. Mix thoroughly.
14. Decorate: Transfer icing to piping bags fitted with small round tips (like PME #1.5 or Wilton #2) or use Ziploc bags with a tiny corner snipped off. Outline your cookies with the stiffer icing, then, if desired, flood with the thinner icing. Allow the outlines to dry for 10-15 minutes before flooding. Let decorated cookies dry completely, preferably overnight (6-8 hours), before stacking or storing. This is important to prevent smudges and to allow the icing to harden properly.
