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.
