These Gingerbread Whoopie Pies combine the warm, spiced flavors of gingerbread with the airy, cakey texture of whoopie pies, creating a delicious treat.
Combine flour, ground ginger, ground cinnamon, ground nutmeg, baking soda and baking powder in a bowl. Sift flour if necessary to remove any lumps. Set bowl aside.
Place molasses and hot water in a large bowl. Whisk together until smooth. Add brown sugar and vegetable oil. Whisk well.
Add egg and whisk well.
Add flour mixture and stir with a spatula until fully combined.
Place plastic wrap or foil over bowl and place in refrigerator for at least 1 ½ hours.
Baking
Preheat oven to 350℉ (177℃)
Prepare two baking sheet pans by lining with parchment paper or silicone baking mats.
Scoop approximately 1 ½ tablespoon-sized mounds onto the prepared baking pans. Leave at least 2 inches between each cookie. Lightly press down on cookie to flatten.
Bake for 8 - 10 minutes. The cookies will be well risen and starting to brown a bit around the edges.
Remove from oven and allow to cool for 10 minutes. Transfer to a wire rack and allow to cool completely.
Filling and assembly
Using a hand-mixer or stand-mixer with the paddle attachment, mix together the cream cheese and butter until well combined and no lumps remain (approximately 2 minutes).
Add the confectioners' sugar, milk and ground cinnamon to the mixing bowl. Mix on low speed and gradually increase the speed to medium. Continue to mix until creamy.
Spread approximately tablespoons of filling on the flat side of half of the cookies (use a spoon or piping bag). Place another cookie on top of the filling and press lightly to seal.
Notes
After scooping dough onto baking pans, remember to slightly flatten dough. This dough does not spread a lot - flattening will create a better looking cookie.
The filling in this gingerbread whoopie pie recipe is perishable. To store, place in an airtight container and place in refrigerator for up to 3 days. If stacking, place layers of wax paper between the cookies to prevent from sticking together.
