In a large bowl, whisk together 6 large eggs, 1 cup milk, 1 cup (or less) sugar, and 1 teaspoon vanilla. Place 8 thick slices of bread in the egg mixture to coat both sides of the bread. While the bread soaks, heat vegetable oil in a large skillet. Fry bread in oil on both sides until golden brown. Serve immediately with warm maple syrup and a sprinkling of powdered sugar.
Sautéed apples or fresh berries would be a nice addition. This dish makes a great dessert or a nice brunch with crispy bacon, sausage or kielbasa and a fresh fruit salad.
