Combine the self rising flour, salt, cocoa powder, sugar, and cream of tartar, in a large bowl.

Sift or mix the ingredients until well combined.

Add all of the dry ingredients into the stand mixer bowl.

Add in the butter, the shortening, buttermilk, and food coloring.

Turn on the stand mixer, and let the ingredients mix on a medium speed, until it turns into red dough.

Once the dough has formed, flatten in out on a lightly floured flat surface using a roll pin ( make sure that you flour the roll pin, so that it does not stick to it).

Cut the biscuits out using a canning lid , biscuit cutter, or cookie cutter.

Place the biscuits into a bake dish ( I used a 9 x 13).

Bake the biscuits on 400 F ( make sure you preheat the oven prior to baking), for 12-15 minutes.

Once done, brush or rub butter on top of the biscuits while they are still warm.

Serve & Enjoy!
