Chocolate Flourless Cupcakes

20 oz. (3½ cups) semi-sweet chocolate
9 oz. (2 sticks and 2 tbsp.) butter, softened
½ cup water
¾ cup white sugar
1 pinch salt
2 large eggs
3 large egg whites

Preheat oven to 300 degrees. Melt chocolate, and put it into a mixing bowl while warm (not hot!) fitted with paddle attachment. Add the softened butter to the melted chocolate on low speed, piece by piece until incorporated. Heat the water, sugar and salt until the sugar and salt are dissolved. Add the warm (not hot!) water mixture to the chocolate mix once the butter is incorporated. 

Add eggs and egg whites to the mixture slowly on the first speed. Mix until incorporated, and then scrape down the sides of the bowl. Mix again to make sure batter is combined. Fill the cupcake cups to a ¼ inch from the top. Bake mini cupcakes at 300 degrees for 30 minutes. Bake standard cupcakes at 300 degrees for 60 minutes.
