Blueberry Cream Cheese Croissant Casserole (Printable)

Buttery croissants baked with creamy cheese filling and juicy blueberries in a rich vanilla custard.

# What You'll Need:

→ Pastry and Filling

01 - 6 large croissants, preferably day-old
02 - 1 cup fresh blueberries
03 - 8 oz cream cheese, softened
04 - 1/2 cup granulated sugar
05 - 2 tsp vanilla extract

→ Custard

06 - 4 large eggs
07 - 1 1/2 cups whole milk
08 - 1/2 cup heavy cream
09 - 1/3 cup granulated sugar

→ Topping

10 - 2 tbsp unsalted butter, melted
11 - Powdered sugar for dusting

# How to Make It:

01 - Preheat oven to 350°F. Grease a 9x13-inch baking dish with butter or cooking spray.
02 - Slice croissants into 1–2 inch pieces. Arrange half in the bottom of the prepared dish and scatter half of the blueberries on top.
03 - Beat together cream cheese, 1/2 cup sugar, and vanilla extract until smooth and creamy. Spread the mixture over the croissants and berries.
04 - Layer the remaining croissants and blueberries on top of the cream cheese mixture.
05 - Whisk together eggs, milk, heavy cream, and 1/3 cup sugar until well combined and smooth.
06 - Pour the custard evenly over the casserole. Press the croissants gently to ensure they absorb the liquid. Drizzle melted butter over the top and let stand for 10 minutes.
07 - Bake uncovered for 35–40 minutes until golden brown and set. Cover loosely with foil during the last 10 minutes if the top browns too quickly.
08 - Let cool for 10 minutes before dusting with powdered sugar. Serve warm.
