A quick and easy cinnamon roll casserole that soaks overnight for a custardy, gooey breakfast treat. Perfect for busy mornings and crowd-pleasing brunches.

Ingredients

Scale
  • 1 package store-bought cinnamon rolls (about 8 rolls; classic or with cream cheese icing included)
  • 1 cup (240 ml) milk (whole or 2%; almond milk as substitute)
  • 2 large eggs, room temperature
  • 1 teaspoon vanilla extract
  • 1 teaspoon ground cinnamon
  • Pinch of salt
  • 1/2 cup (120 ml) cream cheese icing (included with rolls or separate, for drizzling)
  • Optional: 1/4 cup (30 g) chopped nuts (pecans or walnuts)
  • Optional: 1/2 cup (75 g) fresh or frozen berries

Instructions

  1. Preheat your oven to 350°F (175°C). If making the night before, skip to step 3 for prepping to refrigerate overnight.
  2. In a medium bowl, whisk together 2 large eggs, 1 cup (240 ml) milk, 1 teaspoon vanilla extract, 1 teaspoon ground cinnamon, and a pinch of salt until smooth and combined.
  3. Slice each cinnamon roll into quarters using a sharp knife.
  4. Lightly grease a 9×13-inch casserole dish. Spread the cinnamon roll pieces evenly across the bottom. If using nuts or berries, sprinkle them on top now.
  5. Pour the custard mixture over the cinnamon rolls, making sure it seeps through all layers. Press gently with a spatula to submerge pieces slightly.
  6. Cover the dish tightly with plastic wrap and refrigerate overnight or at least 4 hours.
  7. Remove the casserole from the fridge and let it sit at room temperature for about 15 minutes while the oven heats.
  8. Bake uncovered for 35–40 minutes until the top is golden brown and custard is set (a knife inserted should come out mostly clean).
  9. While still warm, drizzle cream cheese icing over the top to melt into the casserole.
  10. Let cool for about 10 minutes before serving to help it settle and make slicing easier.

Notes

Do not skip the overnight soak for best custard texture. Use room temperature eggs and milk to avoid clumps. Grease the dish well to prevent sticking. Tent with foil if top browns too quickly. For quicker results, a 1-hour soak at room temperature works but yields less custardy texture. Customize icing thickness with powdered sugar or milk.
