This easy overnight cinnamon roll casserole is a cozy, indulgent brunch recipe that requires minimal morning effort. Store-bought cinnamon rolls soak overnight in a vanilla-spiced custard, then bake into a soft, gooey, cinnamon-scented delight.

Ingredients

Scale
  • 1 (12 count) package store-bought cinnamon rolls (e.g., Pillsbury)
  • 4 large eggs, room temperature
  • 2 cups whole milk (480 ml / 16 fl oz)
  • 1/2 cup heavy cream (120 ml / 4 fl oz), optional
  • 1/3 cup granulated sugar (65 g)
  • 2 tsp vanilla extract
  • 1 tsp ground cinnamon
  • Pinch of salt
  • Optional toppings: additional cinnamon sugar sprinkle before baking, chopped pecans or walnuts, fresh fruit like sliced apples or berries

Instructions

  1. Lightly grease a 9×13-inch casserole dish with butter or non-stick spray.
  2. Cut each cinnamon roll into quarters using a sharp knife.
  3. Spread the cinnamon roll pieces evenly in the prepared casserole dish without overcrowding.
  4. In a medium mixing bowl, whisk together eggs, whole milk, heavy cream (if using), granulated sugar, vanilla extract, ground cinnamon, and salt until smooth.
  5. Pour the custard mixture slowly over the cinnamon rolls, pressing gently with a spatula to encourage soaking.
  6. Cover the casserole dish tightly with plastic wrap or foil and refrigerate for at least 6 hours or overnight.
  7. Preheat oven to 350°F (175°C).
  8. Remove casserole from fridge, uncover, and bake for 40-50 minutes. Cover loosely with foil if the top browns too quickly. The casserole is done when custard is set and top is golden brown.
  9. Drizzle the included cinnamon roll glaze over the warm casserole before serving. If glaze is not included, mix 1 cup powdered sugar with 2-3 tbsp milk and a splash of vanilla for a quick homemade glaze.

Notes

Do not skip the overnight soak for best custard absorption and tenderness. Cover casserole loosely with foil during last 15 minutes if top browns too quickly. For dairy-free, substitute milk and cream with plant-based alternatives. For gluten-free, use gluten-free cinnamon rolls. Assemble casserole night before but add glaze fresh in the morning for best flavor.
