Ingredients
  

Base Ingredients
  • 2 cans (12.4 oz each) refrigerated cinnamon rolls (such as Pillsbury Grands!) 16 rolls total
  • 1 tablespoon butter for greasing the pan
French Toast Custard
  • 5 large eggs
  • 1 cup whole milk or half-and-half for a richer flavor
  • 1/4 cup granulated sugar or light brown sugar
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon ground cinnamon
  • Pinch salt
Topping
  • 2 icing packets included with the cinnamon rolls (set aside)

Equipment

  • Mixing Bowl
  • 9x13 inch baking dish
  • Sharp knife

Method
 

Preparation and Assembly
  1. Preheat your oven to 375°F (190°C). Grease a 9x13 inch baking dish generously with the tablespoon of butter.
  2. Open both cans of cinnamon rolls, remove the rolls, and set the two small containers of icing aside; you will use these later. Using a sharp knife, cut each of the 16 cinnamon rolls into four equal pieces (quarters).
  3. Scatter the cinnamon roll pieces evenly across the bottom of the prepared 9x13 inch baking dish.
  4. Make the Custard: In a medium-sized bowl, whisk together the 5 large eggs, 1 cup of milk, 1/4 cup of sugar, 1 teaspoon of vanilla extract, 1/2 teaspoon of ground cinnamon, and the pinch of salt until the mixture is uniform and slightly frothy.
  5. Pour the entire egg custard mixture carefully and evenly over the cinnamon roll pieces in the baking dish, ensuring they are fully saturated. Allow the rolls to soak for 10 minutes prior to baking. This crucial step helps create the desired French toast texture.
Baking and Finishing
  1. Bake the Casserole: Place the baking dish into the preheated 375°F (190°C) oven. Bake for 25 to 30 minutes, or until the top is golden brown, the center is set, and the custard no longer appears runny. (An internal temperature of 165°F/74°C is ideal).
  2. Prepare the Icing: While the bake is still hot, warm the reserved icing packets. You can place the packets in a bowl of hot water for 2 minutes or microwave the contents (transferred to a small bowl) for 5 to 10 seconds to make them easily pourable.
  3. Drizzle the warmed icing evenly over the top of the hot casserole. Allow the bake to cool for 5 to 10 minutes before cutting and serving while warm.

Notes

For an extra layer of flavor, try stirring 1/4 cup of chopped toasted pecans or walnuts into the custard mixture before pouring it over the rolls. If you prefer a less sweet dish, you can reduce the granulated sugar in the custard by half, as the icing provides ample sweetness.
