German Pancakes

Or if you prefer, Magic pancakes . . . I've heard it both ways!

6 eggs
1 cup milk
1 cup flour
1/2 cup sugar
1 tsp vanilla
1/2 tsp salt
1 cube butter

Melt the butter in an 11x13 pan in the oven at 350 degrees
Mix everything else for 1 minute with an electric mixer
Pour the mixture over the melted butter and bake for 15 minutes
