I'm making a 9x13 cake for an 11 yr old's birthday party on Friday and I'm not sure if I should just make a single 2" layer and tort it or I should make two 2" layers. I'm going to be icing and filling it with vanilla buttercream (they didn't want a different filling) with a FBCT of the Hogwarts crest on it. What would you do?

depends, how many servings do you need? Making two 2" layers is going to give them double the servings.

I would go with the single 2" layer and torte it for a 2 layer cake . I did a 4 layer 9x13 and it was huge .. way too much cake for the occasion. if you do the math I think you will find that you should be able to get about 24
2x2 servings. HTH

Yes, you need to find out how many servings are required.

No, you can't just slice a 2" tall one-layer cake in half lengthwise and call it a two-layer cake. A layer cake is typically 4" tall regardless of how many times you cut it or how many layers of filling you use.

I was told only 15 people. I'm guessing a mix of adults and kids. My thought is a 2" layer and torte it. It really would be a huge cake otherwise....

I'll see how it goes. Thanks everyone!

Okay... your 9x13 quarter sheet will definitely serve the 15 people expected. Have fun!
