📖 Instructions

1. Preheat the oven to 350°F (175°C). Grease a 9x13 inch baking dish. Really get in there with the grease, so nothing sticks! I speak from bitter experience.
2. Open both cans of cinnamon rolls and set the icing aside. Cut each cinnamon roll into 6-8 pieces. This is the best part – who doesn't love tearing into a cinnamon roll, right?
3. In a large bowl, whisk together the eggs, milk, heavy cream, sugar, vanilla extract, ground cinnamon, and pinch of salt until well combined. Make sure everything is fully incorporated for the best flavor.
4. Arrange the cut cinnamon roll pieces evenly in the prepared baking dish. Spread them out so they all get a good soak in the custard later.
5. Pour the egg mixture over the cinnamon rolls, making sure all pieces are evenly coated. Gently press down on the cinnamon rolls to help them soak up the liquid. Don't be shy, get those rolls nice and saturated!
6. Cover the baking dish with plastic wrap and refrigerate for at least 30 minutes, or preferably overnight. The longer it sits, the more the cinnamon rolls will absorb the custard, resulting in a richer, more flavorful casserole. This step is super important!
7. Remove the baking dish from the refrigerator and let it sit at room temperature for 20 minutes while the oven preheats. This helps the casserole bake more evenly.
8. Uncover the baking dish and bake in the preheated oven for 30-35 minutes, or until the casserole is golden brown and set. A knife inserted into the center should come out clean. Keep an eye on it towards the end to prevent burning. Ovens vary, you know?
9. While the casserole is baking, prepare the icing by microwaving it for 10-15 seconds until it's easily drizzable. Be careful not to overheat it!
10. Once the casserole is done, remove it from the oven and let it cool for a few minutes before drizzling with the prepared icing. Get creative with your drizzling!
11. Slice the Cinnamon Roll French Toast Casserole into squares and serve warm. Enjoy this delightful and comforting breakfast treat! It's even better with a cup of coffee, just saying.
