1/2 cup butter; softened
1 cup sugar
3 cups eggnog
2 eggs
1 teaspoon vanilla
1 teaspoon ground cinnamon
1/2 teaspoon ground nutmeg
1/2 teaspoon salt
1/4 teaspoon cream of tartar
10 slices French bread (preferably stale); toasted

Cut bread into 1-inch pieces and place onto large baking sheet. Toast at 325 degrees F until lightly browned. Set aside. Place the butter and sugar in a large bowl and beat on medium speed until well creamed, about 5 minutes. Add the eggnog, eggs, vanilla, cinnamon, nutmeg, salt, and cream of tartar. Beat on low speed until batter is thoroughly blended. Place toasted bread in the bottom of an ungreased 8 x 8-inch baking pan. Pour the mixture over the bread and allow to soak for about 1 hour. Bake at 450 degrees F for 20-25 minutes, until very well browned and the mixture shakes slightly (like a bowl of jelly) when the pan is gently shaken. Remove from oven and let cool 10-15 minutes before serving. Delicious warm or cold!
