- 8 eggs room temperature
- ½ cup whole milk or half and half
- ¼ cup sour cream
- 1 tablespoon vanilla
- ¾-1 cup sugar divided

Instructions
Instructions
- Spray a 9×13 baking dish with cooking spray. Spread the bread cubes in the dish in an even layer.
- In a 4 cup measuring cup or medium bowl, whisk (or use an immersion blender) and mix together the eggs, milk, sour cream, vanilla, and ¼ cup (use ½ cup if you used brioche or challah) sugar until combined.
- Pour the liquid evenly over the bread pieces. Cover the baking dish with plastic wrap and refrigerate overnight, or at least 6-8 hours.
- Position a rack in the center of the oven and preheat the oven to 350ºF.
- Melt the butter in a microwave-safe bowl. Whisk in ½ cup sugar, cinnamon, and nutmeg, until combined. Drizzle this prepared mixture over the casserole.
- Bake the casserole uncovered for 28-35 minutes or until the casserole is browning and set in the center (test with a toothpick.)
- Allow the casserole to cool for 10-15 minutes before icing.
- While the casserole is baking, beat the softened butter and cream cheese together using a hand mixer, until smooth. Pour in the vanilla, lemon juice, and powdered sugar, and mix until smooth.
- Once the icing is combined, add a teaspoon of milk at a time, mixing thoroughly before adding the next teaspoon. Drizzle the prepared icing over the warm cinnamon roll casserole.
Notes
Serve warm with a drizzle of cream cheese icing.
