# How-To Steps:
01 - Grease a 9 by 13-inch baking dish with butter or cooking spray.
02 - In a mixing bowl, beat softened cream cheese with powdered sugar and lemon zest until smooth and creamy using an electric mixer or whisk.
03 - Arrange half the bread cubes in the prepared baking dish. Evenly distribute the cream cheese mixture over the bread layer. Top with remaining bread cubes.
04 - In a large bowl, whisk together eggs, whole milk, heavy cream, granulated sugar, brown sugar, vanilla extract, cinnamon, nutmeg, and salt until thoroughly combined.
05 - Pour the custard evenly over the bread mixture, pressing down gently to ensure even saturation. Cover tightly with aluminum foil and refrigerate for at least 8 hours or overnight.
06 - Preheat oven to 350 degrees Fahrenheit. Remove the baking dish from the refrigerator and allow it to sit at room temperature while the oven reaches temperature.
07 - In a small bowl, mix together melted butter, granulated sugar, and cinnamon. Drizzle this mixture evenly over the casserole.
08 - Bake uncovered for 40 to 45 minutes until the surface is puffed and golden brown.
09 - Remove from oven and allow to cool for 10 minutes before decorating.
10 - Whisk together powdered sugar, milk, and vanilla extract until smooth and pourable. Drizzle the icing over the warm casserole. Immediately sprinkle with purple, green, and gold sanding sugars in festive stripes.
11 - Serve warm, optionally accompanied with fresh berries or whipped cream.
