Prepare Dry Ingredients: In a medium bowl, whisk together the all-purpose flour, baking soda, baking powder, ground ginger, ground cinnamon, ground cloves, and salt. Set aside.
Cream the Sugars and Butter: In a large mixing bowl, beat together unsalted butter, brown sugar, and granulated sugar until light and fluffy.
Incorporate Wet Ingredients: Add egg, molasses, and vanilla extract to the butter-sugar mixture and beat until smooth.
Combine Dry and Wet Mixtures: Gradually fold the dry ingredients into the wet mixture until a soft dough forms.
Chill the Dough: Wrap the dough in plastic wrap and refrigerate for at least 2 hours.
Preheat the Oven: Preheat your oven to 350°F (175°C) and prepare your baking sheets with parchment paper.
Roll Out the Dough: On a floured surface, roll out the chilled dough to ¼-inch thickness.
Cut and Arrange Cookies: Use cookie cutters to cut out shapes and place them on the baking sheets.
Bake the Cookies: Bake in the preheated oven for 8-10 minutes until edges are firm but centers are soft.
Cool and Fill Cookies: Allow cookies to cool before spreading Nutella on half and sandwiching with another cookie half.
Decorate Your Treats: Sprinkle decorations on top of each Nutella-filled gingerbread man.
Notes
