What is the difference whe cooking a sponge cake between using two sandwich tins and making in one tin and the cutting cake you half?

When using two sandwich tins, a sponge cake bakes evenly and has a uniform thickness, resulting in a consistent texture and quicker baking time. In contrast, baking in one tin requires a longer baking time, and the cake may dome in the center, making it more challenging to achieve even layers when cutting it in half. Additionally, using two tins allows for a more straightforward assembly with frosting or filling between the layers, enhancing presentation and flavor.
