Hi everyone!
I'm baking a cake (using the WASC recipe) in a 9x12" Wilton pan (2" high). I put parchment around the sides hoping to get about a 3" high cake. The Wilton directions said to use 7 cups of batter and bake it at 350 degrees for 35-40 minutes. I used 10 cups of batter and baked it at 325 degrees (because that's what the WASC recipes calls for). Anyone know what baking time I'm looking at approximately? I'm starting at 45 minutes.
Shoot, I just realized that I forgot to use bake even strips, darn! This recipe usually bakes up pretty flat though, maybe I'll be okay.
Thanks in advance.

Everyone on the forum here always states 'when your cake smells done' you could try this, or...

give it 45 minutes and then turn the light on in your oven, if you have one, note the color change on the top, if it is a golden brown color for vanilla, or has slightly risen for chocolate, then test it with a toothpick, if it comes out clean it's done. But DON'T pull the cake out to test, it can collapse.
