To bake a 12x18 sheet cake, it's generally recommended to bake at 350°F (175°C) for approximately 35 to 40 minutes. However, due to variances in ovens and specific batter densities, start checking the cake at 30 minutes. A cake is done when a toothpick inserted into the center comes out clean or with a few crumbs attached. Remember, even heat distribution is key, so ensure to rotate your cake halfway through if your oven has hot spots.
