Melt 1/2 lb. of the cheese with 2 sticks of butter on medium heat.
In a large bowl, mix together 32 oz of powdered sugar (yes, please weigh this for accuracy) with 1/2 cup of the cocoa powder. Stir to get out any lumps.
Mix the melted butter and cheese into the sugar/cocoa blend. It'll get really stiff really quick. Add one teaspoon of vanilla as you are stirring.
Place the candy mixture into a greased 9x13 pan and press down with your hands. Let "set" for at least an hour before cutting...if you can.
