Cream Mixture
- 1 cup whole milk
- 1 cup heavy cream
- 2 large eggs
- 1 cup granulated sugar
- 1 tablespoon vanilla extract
- 1 tablespoon banana extract
- 1/4 teaspoon salt
Casserole Components
- 1 ripe but not overripe banana, sliced
- 6 day-old croissants, cut or torn into 1–2 inch pieces
- Maple syrup, for serving
- Preheat Oven and Prepare Dish: Preheat your oven to 350°F (175°C). Spray an 8 x 8-inch baking dish with cooking spray to prevent sticking and set it aside.
- Make Custard Mixture: In a large bowl, whisk together whole milk, heavy cream, eggs, granulated sugar, vanilla extract, banana extract, and salt until well combined and smooth.
- Soak the Croissants: Add the croissant pieces to the custard mixture, stirring gently to ensure all pieces are fully coated. Allow the mixture to sit for 25 to 30 minutes, stirring about halfway through (around 15 minutes) to help the croissants absorb the custard evenly.
- Assemble the Casserole: Pour the soaked croissant mixture into the prepared baking dish. Arrange the banana slices evenly on top, gently pressing them into the custard-soaked croissants.
- Bake: Bake the casserole in the preheated oven for 45 to 50 minutes, or until the custard is set and the top is lightly browned and golden.
- Rest and Serve: Remove the casserole from the oven and let it rest for 10 minutes to allow it to firm up slightly. Serve warm with maple syrup drizzled on top if desired.
Notes
- Using day-old croissants ensures they soak up the custard well without becoming too mushy.
- You can substitute banana extract with additional vanilla extract and a bit more ripe banana if preferred.
- Letting the mixture sit before baking allows for better absorption and results in a custardy texture.
- Allow the casserole to rest before serving; this makes it easier to cut and serve.
- For added texture, sprinkle chopped nuts or chocolate chips on top before baking.
