Ingredients

Scale

Base

2 cans (8-count each) cinnamon rolls, cut into quarters (reserve icing)
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

1 tsp lemon zest (optional, for a tangy twist)
2 oz cream cheese, cut into cubes (optional, adds creaminess)

Instructions

Preheat and Prepare Pan: Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish to prevent sticking.
Assemble Base: Spread the quartered cinnamon roll pieces evenly in the greased baking dish to form the casserole base. Sprinkle the blueberries over the top to distribute them evenly.
Mix Custard: In a bowl, whisk together the eggs, milk, granulated sugar, vanilla extract, and cinnamon until fully combined. For an optional tangy twist, you may add lemon zest or cube cream cheese and scatter it over the rolls before pouring the mixture.
Pour and Bake: Pour the custard mixture evenly over the cinnamon roll pieces and blueberries. Bake the casserole in the preheated oven for 35 to 40 minutes, or until the top is golden brown and the custard is fully set.
Finish with Icing: Warm the reserved cinnamon roll icing slightly until pourable, then drizzle generously over the baked casserole. Optionally, add extra powdered sugar or maple syrup to taste for added sweetness.

Notes

Use fresh or frozen blueberries depending on availability; no need to thaw if frozen.
To enhance flavor, let the casserole cool slightly before serving to allow the custard to fully set.
For a dairy-free version, substitute milk with almond or oat milk and use cinnamon rolls without dairy.
Adding lemon zest or cream cheese is optional but provides a nice contrast to the sweet cinnamon flavor.
Check for doneness by inserting a toothpick in the center – it should come out clean.
