# What You'll Need:
→ Bread & Custard
01 - 1 loaf (16 oz) brioche or challah, cut into 1-inch cubes
02 - 6 large eggs
03 - 2 cups whole milk
04 - 1/2 cup heavy cream
05 - 1/2 cup granulated sugar
06 - 2 teaspoons vanilla extract
07 - 1/2 teaspoon ground cinnamon
08 - 1/4 teaspoon ground nutmeg
09 - 1/4 teaspoon salt
→ Apple Pie Filling
10 - 3 medium apples (e.g., Granny Smith), peeled, cored, and diced
11 - 2 tablespoons butter
12 - 1/3 cup brown sugar
13 - 1 teaspoon ground cinnamon
14 - 1/4 teaspoon ground allspice
15 - 1/2 teaspoon lemon juice
→ Streusel Topping
16 - 1/2 cup old-fashioned oats
17 - 1/3 cup all-purpose flour
18 - 1/3 cup brown sugar
19 - 1/2 teaspoon ground cinnamon
20 - 1/4 cup cold butter, cubed
# How To Make It:
01 - In a medium skillet over medium heat, melt 2 tablespoons butter. Add diced apples, brown sugar, cinnamon, allspice, and lemon juice. Cook, stirring frequently, for 5 to 7 minutes until apples are tender. Remove from heat and allow to cool slightly.
02 - Grease a 9x13-inch baking dish. Evenly spread the brioche or challah cubes across the dish. Spoon the cooked apple mixture evenly over the bread cubes.
03 - In a mixing bowl, whisk together eggs, whole milk, heavy cream, granulated sugar, vanilla extract, ground cinnamon, nutmeg, and salt until smooth.
04 - Pour the custard mixture evenly over the bread and apple layers, pressing gently to ensure all bread cubes are fully soaked.
05 - Cover the dish tightly with plastic wrap and refrigerate for at least 6 hours or overnight to allow flavors to meld and bread to absorb custard.
06 - Remove the dish from the refrigerator and preheat the oven to 350°F (175°C).
07 - In a bowl, combine oats, all-purpose flour, brown sugar, and cinnamon. Cut in cold butter using a fork or fingers until mixture resembles coarse crumbs. Evenly sprinkle the streusel over the soaked casserole.
08 - Bake uncovered for 40 to 45 minutes until the custard is set, the top is puffed, and streusel is golden brown.
09 - Allow to stand for 10 minutes before slicing and serving to enhance texture and flavor.
