In a large bowl combine the eggs, half and half, sugar, and vanilla extract. Whisk until all the eggs are fully broken down and the mixture is smooth. It might be helpful to use a handheld mixer, but it isn't necessary.
4 large eggs, 2 cups half and half, 1 cup sugar, 2 teaspoons vanilla extract
Add the dried bread and toss to combine. Let the bread sit, soaking in the custard, for 20 minutes.
10 ounces brioche bread
Preheat your oven to 350 degrees Fahrenheit. Spray a 2 quart inch baking dish with cooking spray and set aside.
Pour the bread and custard mixture into the prepared baking dish.
Bake for 35 to 45 minutes uncovered or until the edges of the bread pudding begin to pull away from the sides of the baking dish and the center looks set. Remove from the oven and allow to cool for 10 minutes before cutting into squares.
