Step 1: Preheat the Oven

Begin by preheating your oven to 350°F (175°C).

Allowing the oven to fully heat before baking ensures the dessert cooks evenly and develops that perfectly golden top layer. While the oven warms up, lightly grease your baking dish or line it with parchment paper for easier cleanup.
