Ingredients
3 large eggs
1 large egg yolk
1 cup sugar
1 tablespoon pure vanilla extract
1/4 teaspoon ground cinnamon
2 cups half-and-half
1 cup whole milk
4 or 5 day-old plain bagels, crusts removed and cut into 1/2-inch cubes (8 cups)
Unsalted butter, for baking dish
1 1/4 cups halved pitted prunes (8 1/2 ounces)
3/4 cup seedless raisins (3 1/2 ounces)
Vanilla ice cream, for serving
Preparation
Whisk together eggs, egg yolk, sugar, vanilla, and cinnamon in a large bowl until smooth. Whisk in half-and-half and milk. Add bagel cubes, and toss to coat. Let mixture sit, stirring occasionally, until bread absorbs some of the liquid, about 1 hour.
Preheat oven to 325 degrees. Butter an 8-inch square baking dish (2 inches deep). Stir prunes and raisins into bagel mixture, and transfer to dish. Bake until top is golden brown and a toothpick inserted in center comes out clean, about 1 hour (if top browns too quickly, tent with foil). Let cool completely on a wire rack. Cut into squares, and serve with ice cream.
