CHOCOLATE PUDDING CAKE
In a small bowl, cream together
1 cup granulated sugar
3 Tablespoons powdered, unsweetened cocoa
3 Tablespoons flour (not self rising)
3 Tablespoons butter at room temp
In another bowl, beat well
3 egg yolks
1 cup milk
1 teaspoon vanilla extract
dash of cinnamon, optional
Mix the sugar/chocolate with the eggs and milk.
In yet another bowl, whip the egg whites until stiff peaks form. Gently fold into the chocolate mixture. Place in ovenproof bowl and set that bowl into another bowl of hot water. The water should rise almost to the level of the pudding.
Bake at 350 40-50 minutes until toothpick inserted in cake layer comes out clean.
I see no reason why you could not either warm the milk and add a couple tablspoons of instant coffee, or substitute strong coffee for half the milk.
