All you need is a trusty mixer, oven, ~Oreo baking pan~, and the proper baking ingredients.
To get started, coat your cookie pans with vegetable oil and pre-heat your oven to 350ºF.
Sift 530 grams of cake flour, 16 grams of baking powder, 100 grams of black cocoa powder, and 70 grams of cocoa powder in a mixing bowl.
Beat 14 eggs in a larger mixing bowl, and then add 350 grams of sugar, a dab of salt, and 210 grams of vegetable oil to the eggs.
Now, dump in you bowl of dry ingredients into the egg mix and MIX AWAY. Then, add 140 grams of milk to your batter.
Pour that BEAUTIFUL, CHOCOLATELY concoction into your pans, and PLEASE don't forget to lick the spoon.
After baking for 40 minutes, slice the tops of the cake off to form a flat surface, and remove the "cookies" from the molds.
Now, while the cakes are cooking, GET INTO THAT ICING. Beat 400 milliliters of heavy whipping cream and 15 grams of sugar until it forms peaks.
Fold in 18 crushed Oreos (or as many as you want, TBH), and try not to drool.
Gently spread it between the "cookies" and die of happiness.
