In a medium bowl, whisk together the flour, baking powder, baking soda, salt, ginger, cinnamon, cloves and nutmeg.
2 cups (240g) all-purpose flour, ½ teaspoon baking powder, ¼ teaspoon baking soda, ½ teaspoon salt, 1 teaspoon ground ginger, 1 teaspoon ground cinnamon, ½ teaspoon ground cloves, ½ teaspoon ground nutmeg
In the bowl of a stand mixer fitted with the paddle attachment, beat butter and brown sugar for 2-3 minutes at medium speed, until light and creamy. Add the molasses, egg yolk and vanilla and beat until combined. Scrape down the sides of the bowl as needed.
½ cup (113g) unsalted butter, ⅓ cup (67g) packed light brown sugar, ½ cup (120mL) molasses, 1 egg yolk, 1 teaspoon vanilla extract
Reduce mixer speed to low and mix in the flour mixture.
Form the dough into a disk and wrap in plastic wrap. Chill in the refrigerator for at least 2 hours and up to 2 days.
When you’re ready to bake the cookies, preheat oven to 350° F.
Using a floured rolling pin, roll out the dough (it will be somewhat sticky) on a floured work surface to ¼-inch thickness. Use cookie cutters to cut cookies into desired shapes. Place on a parchment-lined baking sheet, about an inch apart. Re-roll scraps of dough until all dough has been used.
Baking time will vary depending on the size of your cookies. Medium (3-inch) gingerbread cookies bake for 7-9 minutes, and mini cookies bake for about 5-7 minutes. Larger cookies will take longer to bake. Let cookies cool for a few minutes on the baking sheet and then transfer to a wire rack to cool completely.
To Decorate: Once cookies are cool, pipe icing onto cookies to decorate as desired. I use a piping bag and Wilton #2 piping tip to decorate these cookies. To make the icing, add the powdered sugar and vanilla to a medium bowl. Then stir in the water, 1 teaspoon at a time, until the icing reaches your desired consistency. It should be fairly thick for piping onto the cookies. If it's too thin, stir in a little more powdered sugar. If it's too thick, stir in a little more water.
