Pre-heat oven to 450 F degrees. Grease three 6 oz ramekins very well with oil or butter. I like to use a non-stick spray with flour that you can find at grocery stores in the baking aisle and grease the ramekins really well. Set them aside.In a large bowl sift together flour, cocoa powder, baking powder, baking soda, instant coffee powder (if using) and salt. Mix until it's all well combined and set it aside.
