Bundt Cake Pan – Best Price!

it will be less than 35 minutes, maybe 20 minutes, same temp., after 20 stick a knife or toothpick in the center of ur 9×13 pan and see if it comes out clean if it does its done, or press the center of the cake lightly with ur finger and if it pops/springs back up than ur cake is done, or as the cake (sides) slightly pulls away from the pan its done

You can’t make angel food cake in that kind of pan.

cut the cooking time by 10 minutes.. the temps stays the same , have you ever seen it in stores in a loaf, same thing keep an eye on it once it hits 25 minutes of baking time

Be careful substituting a pan when the recipe indicates that a tube pan should be used, such as an angel food cake pan or a bundt pan. Generally the recipe requires this type of pan so the heat is distributed properly. This is necessary for the food to get to its proper doneness.

Good Luck!

Remember not to use a non-stick pan and make sure you cool the cake upside down. I’ve never seen a 9"x13" pan with "feet," so it may be tricky keeping the pan upside down while cooling if the cake baked into a dome above the top of the cake pan.

Some people say that you can cut time off of the total cooking time because your cake won’t be as thick as one would be in a tube pan. However, the tube in the pan allows for better heat distribution, therefore decreasing the total cooking time. So, I’d start watching your cake at around 25 minutes, but I bet it’ll cook for almost as long in a 9"x13" as the time indicated for a tube pan.
