What happens when you don't flour a cake pan?

When you don't flour a cake pan, the batter can stick to the sides and bottom of the pan after baking. This may lead to difficulty in removing the cake, resulting in breakage or an uneven shape. Additionally, the lack of flour can prevent the cake from achieving a desirable texture and appearance, as it can stick and create a messy presentation. Properly preparing the pan with flour ensures a smooth release and a more aesthetically pleasing cake.
