Sift the flour, cocoa , corn starch, cinnamon, chili powder, cayenne, nutmeg, and salt in a bowl and set aside.
Cream the room temperature butter and sugar until combined, about a minute, then add in egg, vanilla, and coffee and combine well (about another minute).
Add flour in two batches. Mix until it comes together. Don't over mix.
Cut two sheets of parchment paper and plop the dough onto one and press down to a semi-rectangle then top with second piece of parchment.
Roll out the dough that is in between the parchment to 1/4 inch thickness and then stick in the refrigerator for at least an hour, to firm up.
Take out and release the parchment from one side so it is not sticking and then lay it back onto the cookies and turn the dough around and release the other side and leave it off so you can cut the cookies.
Cut the cookies into any shape you like and lay them on a parchment lined cookie sheet (use the parchment you already have cut).
Bake cookies for about 9-12 minutes (plus or minus depending on how large/thick you make the cutouts) in a preheated 350 degree Fahrenheit oven, remove and completely cool before icing.
