Cake pan baking times can vary depending on several factors, including the type of cake, the size and shape of the pan, the temperature of your oven, and whether you're baking at high altitude. Here are some general guidelines for common cake pan sizes and types:

Round Cake Pans:

• 6-inch round pan: 25-35 minutes

• 8-inch round pan: 30-40 minutes

• 9-inch round pan: 35-45 minutes

Square Cake Pans:

• 8-inch square pan: 30-40 minutes

• 9-inch square pan: 35-45 minutes

Rectangular Pans (such as 9x13 inches):

• 25-35 minutes for a cake mix

• 35-45 minutes for a from-scratch cake

Bundt Pans:

• Typically 40-60 minutes, depending on the size and complexity of the pan

Layer Cakes:

• Usually baked in multiple 8- or 9-inch round pans for 25-35 minutes each

Sheet Cakes:

• Half sheet (13x18 inches): 20-30 minutes

• Full sheet (18x24 inches): 30-40 minutes

Remember to preheat your oven to the temperature specified in your recipe, which is often between 325°F and 375°F (160°C and 190°C). To test if your cake is done, insert a toothpick or cake tester into the center of the cake. If it comes out clean or with a few crumbs attached, the cake is ready. If batter is on the toothpick, the cake needs more time.

Always check your cake a few minutes before the minimum time in the range to prevent overbaking. Oven temperatures can vary, so it's important to use these times as a guide and adjust based on your specific circumstances.
