Ingredients

Scale

Base

2 cans (8-count) cinnamon rolls, cut into quarters (icing reserved)
1 cup fresh or frozen blueberries

Custard Mixture

4 large eggs
1/2 cup (120ml) milk
1/4 cup (50g) granulated sugar
1 tsp vanilla extract
1/2 tsp cinnamon

Optional Twist

1 tsp lemon zest
2 oz cream cheese, cut into cubes

Instructions

Preheat the Oven: Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish thoroughly to ensure the casserole doesn’t stick.
Prepare the Base Layer: Cut the cinnamon rolls into quarters, reserving the icing. Spread these pieces evenly across the bottom of the prepared baking dish, creating a base layer.
Add Blueberries: Sprinkle a cup of fresh or frozen blueberries evenly over the cinnamon roll pieces to distribute their sweetness and tartness throughout the casserole.
Make the Custard: In a mixing bowl, whisk together the eggs, milk, granulated sugar, vanilla extract, and cinnamon until the mixture is smooth and well combined. For a tangy flavor, optionally whisk in lemon zest or add cream cheese cubes on top before baking.
Pour Custard Over Rolls: Carefully pour the custard mixture evenly over the cinnamon roll quarters and blueberries in the baking dish, allowing it to soak into the pieces.
Bake: Place the dish in the preheated oven and bake for 35 to 40 minutes until the casserole is golden brown on top and fully set in the middle.
Finish with Icing: While warm, slightly warm the reserved cinnamon roll icing and drizzle it generously over the top of the casserole. For additional sweetness, you can also sprinkle powdered sugar or drizzle maple syrup if desired.

Notes

Using frozen blueberries is fine; just thaw slightly before adding or add them directly if you prefer.
If you opt for the cream cheese addition, dot small cubes evenly over the cinnamon rolls before pouring custard for pockets of creamy tang.
Make sure to grease the baking dish well to prevent sticking.
Leftovers can be refrigerated for up to 3 days and reheated gently in the microwave or oven.
This casserole can be assembled in advance and baked just before serving.
