This Zucchini Sheet Cake is absolutely delicious! It feeds a crowd and is the perfect way to use up some zucchini. The cream cheese frosting makes it even better!

Is it pretty pathetic that it’s only 7:40 PM and as I’m sitting here typing this post I am struggling to keep my eyes open?
Sometimes my eyelids all of a sudden feel like they weigh 100 pounds each and it’s all I can do to keep them open.
I remember one year I was sitting down signing our Christmas cards and addressing envelopes. I was getting really, really tired and was fighting to keep my eyelids open, but I kept signing cards. Once I finally snapped out of my incoherent state, I noticed that instead of signing a couple of the cards Love, The Ludlows I had written 8768 South 1185 East . . . oops! Glad I caught it before sending those cards out, that would have been so embarrassing.
So I’m thinking I’d better just play it safe and get right down to business here before I type something that I regret.
I love all things zucchini. This Zucchini Sheet Cake is absolutely delicious and is now at the top of my zucchini favorites list. It’s so moist and I love the flavor the cinnamon and allspice give it.
The cream cheese frosting tops it off and makes it even more fabulous . . .doesn’t cream cheese frosting make everything better? I am definitely going to make this again and try it with the amazing caramel frosting on my favorite zucchini cupcakes.
You absolutely need make this zucchini cake. If you didn’t plant zucchini I’m 98.6% sure you can find a neighbor, friend or family member who has an overabundance of them they would happily share.

Is it possible to increase this recipe for a 12 x 18 pan. Feeding larger crowd here.
Hi Mary! This recipe uses a jelly roll pan with is 10×15, doubling it would be too much batter for a 12×18 pan. You might be able to make 1 1/2 the recipe and use the larger pan, but I haven’t ever tried it so I’m not sure if that would also be too much batter. You could always make the recipe as is and bake it in the larger pan, the cake would just be thinner than in the pictures.
