The slices are thin, like a sheet cake should be. If you would like to bake this in a 9×13 you’ll need to decrease the oven temperature to 350° and increase the bake time to about 20 minutes!

    Cake just wasnt good. I used good ingredients. Made it twice because thought i over mixed first one but nope second time around turned out same. Even waited a day. Its more dense than pound cake and way not buttery. I made cake cause of how many stars it was only afterwards i read these reviews. Most have not actually made cake.

    Do you think it would be possible to decorate this with fruit on top after icing? Or would the consistency of the icing prevent this?

    I have made the chocolate Texas sheet cake many times, but the event I am making it for required a white or yellow cake. Since I am familiar with this type of recipe I knew it would be thin. I upped the whole recipe by 1/2 and baked it in a deeper pan that was the same size 11×17. And I used some vegetable oil with the melted butter with out any problems.
    It did require longer baking to finish it. But its a perfect easy recipe.
    Love seeing the boy making the recipe in the photos. That is how I learned to bake too, as a kid many many years ago with my grandmother. Thanks for the recipe.

        I just wanted a really good yellow cake recipe for my little boy’s birthday but wanted it to be more like a birthday cake. This seems more like a dessert bar/denser cake and not so much fluff….am I right? Looks awesome! I just hope it works!
