This easy cinnamon roll casserole uses Pillsbury refrigerated dough for a soft, gooey breakfast that comes together in just 35 minutes. Perfect for holidays or weekend brunch!
Prep. Preheat the oven to 375°F. Spray a 9x13-inch baking dish with nonstick cooking spray.
Cut cinnamon rolls into quarters. Open 2 cans refrigerated cinnamon rolls and set aside the included icing packet for later. Cut each cinnamon roll into quarters.
Egg/custard mixture. In a large bowl, whisk together 4 eggs, 1/2 cup half and half, 2 Tablespoons maple syrup, 2 teaspoons vanilla extract, and 1/2 teaspoon ground cinnamon until well combined.
Assemble casserole. Dip a cinnamon roll piece into the egg mixture, evenly coating all sides, and place in the baking dish. Repeat with the remaining the cinnamon roll pieces. Sprinkle the top with pecans, if using. Pour remaining egg mixture over the top to ensure the pieces get covered.
Bake. Bake 25 to 30 minutes, or until the cinnamon rolls are golden brown and a toothpick inserted into the center comes out clean with no wet dough. Cool slightly.
Combine icing ingredients. In a small bowl, stir together the sour cream and included icing until smooth.
Drizzle icing over casserole and serve. While the casserole is still warm, drizzle the icing mixture over the top. Serve warm and enjoy!
