The ingredient list alone cannot explain how dough behaves under high heat when loaded with sugar. Yeast-based dough requires structural integrity before sweet toppings are applied. Baking the crust plain at 450 degrees Fahrenheit creates the necessary rigid foundation. Without this initial bare bake, the heavy spread and melting chips will saturate the interior and prevent the center from crisping.
Prepared crusts can be baked ahead and stored in an airtight container at room temperature for up to two days. Wrap the unadorned baked circle tightly in plastic wrap to block moisture absorption. When assembling later, apply the Nutella while the crust is slightly warm to ease spreading without tearing the crumb. Reheating requires a low oven setting of 300 degrees Fahrenheit for five minutes. High heat will scorch the dairy solids in the milk and white chocolate chips.
