Preheat the oven to 350 degrees. Combine the flour, cocoa powder, baking soda, salt, shortening, sugar, vanilla, and egg in a mixer until well mixed. Add water slowly until it reaches a good cookie consistency -- this was about 2 TBSP for us, but might differ for you depending. You need to be able to roll the dough into balls, so don't let the dough get too sticky. Roll cookie dough into small balls, no larger than 1/2 inch in diameter. Bake on a cookie sheet at 350 degrees for about 7-9 minutes, but keep an eye on things so they don't get overcooked on the bottom. Place on cooling rack. When the cookies cool, find matches and put
cream cheese frosting between each pair of cookies. (Note to future self: half a batch of frosting should do.) Yum!
