🍴 Ingredients
- The “Dough” Foundation:
- 2 cans (12.4 oz each) Refrigerated Cinnamon Rolls (cut into 1-inch cubes)
- Keep the icing from the cans for the finish!
- The “French Toast” Custard:
- 1 cup Whole milk or Half-and-half
- 3 Large eggs (beaten)
- 1 tsp Vanilla extract & ½ tsp Ground nutmeg
- 2 tbsp Melted butter
- The “Streusel” Topping:
- ½ cup Pecans or Walnuts (chopped)
- ¼ cup Maple syrup (drizzled over the top before baking)
👩🍳 Instructions
1. The Cube & Dry
- Cut each raw cinnamon roll into 6–8 small cubes.
- Spread them out on a baking sheet and let them sit for 20 minutes. This “skin” prevents the dough from melting into the milk later.
2. The Custard Whisk
- In a large bowl, whisk together the milk, eggs, vanilla, nutmeg, and melted butter.
- The Pro Move: Do not add extra sugar! The cinnamon rolls and the icing already provide all the sweetness necessary.
3. The Overnight Soak
- Grease a 9×13 inch baking dish. Layer the dough cubes evenly in the dish.
- Pour the custard mixture over the dough, ensuring every cube is touched by the liquid.
- Cover tightly with plastic wrap and refrigerate for at least 8 hours (or up to 24).
4. The Maple Bake
- Preheat your oven to 175°C (350°F).
- Remove the plastic wrap and drizzle the maple syrup and chopped nuts over the top.
- Bake for 25–30 minutes.
- The Visual Cue: The casserole should be puffed up high and the edges should be a dark, “cinnamon-stick” brown.
5. The Icing Drizzle
- Warm the reserved icing from the cans for 10 seconds in the microwave.
- Drizzle the icing over the hot casserole immediately. Let it sit for 5 minutes to “set” before serving.
The “Apple-Pie” Hack: Before the overnight soak, stir in 1 cup of finely diced apples (tossed in cinnamon). They will soften beautifully in the custard, turning this into an “Apple Fritter” style breakfast bake.
