Chop the butter into Tbs, approx, so it melts faster, put the pieces into a 1 qt sauce pan on med heat. Meanwhile, measure out the cocoa, crack your eggs and measure your dairy or milks. If you don't have whipping cream, use a half cup of whole milk.

When the butter is bubbling, use a 2" whisk to mix the sugar into it and add the cocoa. Mix completely. It's going to be very grainy! Keep mixing.

At this point you can begin preheating your oven to 350°F (180°C). Now take the pot off the heat and begin adding the milk in a bit at a time. The mass of chocolate will separate but DON'T stop mixing! Keep adding the milk, approximately a Tbs at a time until it's ALL mixed in. By the time the last of it goes in you'll see a smooth, silky sauce. If not, don't worry, begin adding an egg and keep mixing until it disappears, and so on until they're ALL gone.

Only grease an 8 x 8 (square) pan. You can also add parchment but it's not necessary. Pour the mixture into the prepared pan and use a spatula to make sure not a single drop gets left behind in the pot!

The original instructions said to bake for 25 minutes but it didn't indicate how big the pan was and I took mine out and it was STILL REALLY raw! After another 25 minutes it was perfect so I'll say 50 minutes cooking time and a clean skewer or tooth pick or whatever you use to check your cakes should come out clean.

Cut pieces in the pan. If you used parchment, remove with the paper to a cooling rack before cutting it on a plate.
