Preheat oven to 350 degrees F and line a half sheet pan (13x18 inches) with parchment paper. Lightly grease parchment paper and up the sides of the pan with cookie spray or cooking oil.
In the bowl of a stand mixer with paddle attachment or in a large bowl with a hand mixer, beat together butter and shortening until smooth. Add both sugars and beat until light and fluffy, 2-3 minutes.
Mix in molasses, corn syrup, egg, and vanilla until combined.
In a separate large bowl, whisk together flour, baking soda, baking powder, ginger, cinnamon, nutmeg, cloves, and salt.
Add dry ingredients to wet ingredients and mix on low until dough is soft, thick, spreadable.
Transfer dough to prepared baking sheet. I recommend dropping the dough in several large scoops placed around the pan rather than piling it all in the center. This will make it easier to spread.
Using an oiled offset spatula or wet hands, spread dough into a ¼" thick layer, going to the edges of pan. Keep thickness as even as possible.
Bake 10-12 minutes, until edges of cookie are just set and the center springs back softly. Take care not to over-bake as Little Debbie cookies are soft and chewy and not crispy.
Let cookie cool completely in pan.
Once cooled, lift cookie out of pan and onto a large cutting board. Using a gingerbread man cookie cutter, cut cookies out. You'll have some cookie scraps leftover. Save to eat!
Using a small offset spatula, frost cookies with vanilla icing. Sprinkle red and green sanding sugar over them.
