Preheat the oven to 400 degrees F (200 degrees C). Line a baking sheet with parchment paper.
Mix shortening, brown sugar, white sugar, egg, vanilla extract, instant coffee, warm water, and cocoa powder together in a bowl until smooth. Add baking soda and 1/3 cup flour. Continue adding flour 1/3 cup at a time until fully incorporated. Mix in oats and chocolate chips.
Use a small cookie scoop to place 12 cookies on the prepared baking sheet.
Bake in the preheated oven for 10 minutes. Remove from the oven and let cookies sit 5 minutes. Transfer cookies to a wire rack to cool completely.
Repeat 2 more times with remaining dough to make 36 cookies.
