Melt a stick of butter, then let it cool slightly in the pan.
8 tbsp butter
Whisk together flour, ground ginger, cinnamon, cloves, nutmeg, baking soda, and salt in a medium mixing bowl. Set aside.
2 cups all-purpose flour, 2 tsp ground cinnamon, ½ tsp ground ginger, ½ tsp ground nutmeg, ½ tsp salt, ¼ tsp ground cloves, ¾ tsp baking soda
In a separate mixing bowl, whisk together melted butter, brown sugar, crystallized ginger, and molasses.
¾ cup brown sugar, ¼ cup molasses or sorghum, 3 tbsp crystallized ginger
Add egg, buttermilk, and vanilla to the mixture and whisk it until combined.
1 large egg, ¼ cup buttermilk, 1 tsp vanilla extract
Add the flour mixture to the wet ingredients.
Stir everything together using a rubber spatula until dough forms.
Cover the bowl with plastic wrap and refrigerate for at least 1 hour, or up to 48 hours.
Once ready to bake, preheat the oven to 350° F, then line 2 baking sheets with parchment paper.
Roll the gingerbread dough into 24 small balls, roughly one tablespoon each. Each ball should be around 35 grams (you can measure them using a kitchen scale.) Space the gingerbread balls evenly on the baking sheet, about 2 inches apart.
Bake them until they’re just set, taking about 12-14 minutes. Watch the cookies closely; they should puff and start to brown around the edges.
Then, transfer them to the cooling rack and allow them to cool completely.
Using a hand mixer (or stand mixer) with a paddle attachment, beat butter for about 2 minutes or until it turns fluffy. Cut the softened cream cheese into 6-8 cubes and add 1 cube at a time, blending completely after each addition. Beat in vanilla and a pinch of salt (if using unsalted butter).
6 tbsp butter, 6 ounces cream cheese, ½ tsp vanilla extract, Pinch of salt
Spoon or pipe a generous amount of filling on the flat side of 12 cookies, then top with the remaining 12 cookies until they form a sandwich.
Dust the whoopie pies with powdered sugar.
1 ½ cups powdered sugar
Serve and enjoy!
