Use a small saucepan (2 quart is a good size) for this recipe. In that saucepan, whisk together the sugar alternative, butter, evaporate milk, and egg yolks. Then place the saucepan on low to medium heat. Whisk or stir constantly while this mixture heats up. When it begins to thicken and turn brown, about 10-12 minutes.
Remove the frosting from the heat and stir in the remaining ingredients. Allow this to cool before using. This should be enough frosting for a two layered German Chocolate Cake. Please refrigerate the frosting and the frosted cake.
