    This looks so good! Is it possible to make this without banana? I love the idea of the cookies and cream part of this cake, but don’t love the taste of banana. Would it be possible to leave out the banana or substitute it for something else? Thank you!

      Hi Channing, I haven’t tested the cake without the banana, so I can’t say it would turn out like it should. I have a classic Texas Sheet Cake recipe you might like. You could add crushed Oreo Cookie to the top of the icing as it sets.
