A simple and delicious overnight cinnamon roll French toast casserole that is soft, custardy, and perfect for busy mornings or relaxed weekends. Made with store-bought cinnamon rolls soaked in a vanilla-spiked custard and baked to a golden caramelized top.
Use room temperature eggs and dairy to avoid curdling. Do not skip the overnight soak for best texture. Cover loosely with foil if the top browns too quickly. Let rest after baking for easier slicing. Use a sharp or serrated knife to cut neat squares. For a crispier top, brush with melted butter before baking. Variations include adding fruit, nuts, or spice changes.
