A simple and indulgent breakfast casserole made by soaking store-bought cinnamon rolls in a rich custard overnight and baking to golden perfection. Perfect for busy mornings or special occasions.

Ingredients

Scale
  • 8 large store-bought cinnamon rolls (about 12 ounces/340 grams), cut into quarters
  • 6 large eggs, room temperature
  • 2 ½ cups (600 ml) whole milk
  • ½ cup (120 ml) heavy cream
  • ⅓ cup (65 grams) granulated sugar
  • 2 teaspoons vanilla extract
  • 1 teaspoon ground cinnamon
  • Pinch of salt
  • 2 tablespoons unsalted butter, melted, for brushing on top
  • Optional: Maple syrup or cream cheese glaze for drizzling
  • Optional: Chopped pecans or walnuts for sprinkling before baking

Instructions

  1. Cut each cinnamon roll into quarters to create about 32 pieces.
  2. Spread the cinnamon roll pieces evenly in a 9×13-inch casserole dish, layering loosely.
  3. In a large bowl, whisk together 6 eggs, 2 ½ cups whole milk, ½ cup heavy cream, ⅓ cup granulated sugar, 2 teaspoons vanilla extract, 1 teaspoon ground cinnamon, and a pinch of salt until smooth and frothy.
  4. Pour the custard mixture evenly over the cinnamon roll pieces, pressing down lightly to help absorption.
  5. Brush the melted butter over the top of the casserole for a golden crust.
  6. Cover tightly with aluminum foil or plastic wrap and refrigerate for at least 6 hours, ideally overnight.
  7. Preheat oven to 350°F (175°C). Remove foil and bake uncovered for 45-50 minutes until puffed and golden brown. A knife inserted should come out clean.
  8. Let rest 5-10 minutes before serving. Optionally drizzle with maple syrup or cream cheese glaze.

Notes

Cut cinnamon rolls into quarters for better custard absorption. Let soak overnight for best texture. Brush melted butter on top before baking for a golden crust. Tent with foil if edges brown too quickly. Can add nuts or fruit layers for variation. Use gluten-free or vegan substitutes as needed.
