These are simple to make and such a surprise when you bite into them. I made them the first time for my son's 5th birthday party. That was 25 years ago! They are always a huge hit and the best part...no frosting required.
Combine second set of ingredients: flour, cocoa, salt, oil, vanilla, sugar, baking soda, water and vinegar in a separate bowl. Fill paper lined muffin tins 2/3 full with cocoa mixture. Top each with a spoonful of cream cheese mixture.
Bake @ 350 degrees for 30-35 minutes. DO NOT FROST
