# Zutaten:
→ Croissants
01 - 6 large all-butter croissants, preferably day-old
→ Custard Mixture
02 - 6 large eggs
03 - 2 cups whole milk
04 - 1 cup heavy cream
05 - 1/2 cup granulated sugar
06 - 2 teaspoons pure vanilla extract
07 - 1/2 teaspoon ground cinnamon
08 - 1/4 teaspoon fine sea salt
→ Berries
09 - 1.5 cups mixed fresh berries (blueberries, raspberries, strawberries, blackberries)
→ Topping
10 - 2 tablespoons unsalted butter, melted
11 - 2 tablespoons turbinado or demerara sugar
12 - Powdered sugar for dusting, optional
13 - Maple syrup for serving, optional
# Zubereitung:
01 - Preheat oven to 350°F. Grease a 9x13-inch baking dish with butter.
02 - Slice croissants horizontally and layer half of the pieces in the bottom of the baking dish. Sprinkle half of the mixed berries evenly over the croissants. Layer remaining croissant pieces on top and scatter remaining berries over them.
03 - In a large mixing bowl, whisk together eggs, milk, cream, granulated sugar, vanilla extract, cinnamon, and salt until smooth and well combined.
04 - Slowly pour the custard mixture evenly over the croissants, pressing gently to help the croissants absorb the liquid. Let the casserole sit at room temperature for 15 minutes, or cover and refrigerate overnight for deeper flavor.
05 - Drizzle melted butter over the top and sprinkle with turbinado sugar.
06 - Bake uncovered for 40–45 minutes, or until the top is golden and the custard is set but still slightly wobbly in the center.
07 - Remove from oven and let rest for 10 minutes before serving. Dust with powdered sugar and serve with maple syrup if desired.
