What You’ll Need

  • salted butter– For most of my baking I use salted butter, but unsalted butter works just fine here too.
  • granulated sugar– Granulated sugar is a fine sugar commonly used in baking/cookie recipes.
  • sour cream– Find sour cream in the dairy section of the grocery store. It keeps the cake soft and moist.
  • ripe bananas– When your bananas turn spotted brown, they’re perfect for baking.
  • pure vanilla extract- When shopping for vanilla, look for the pure vanilla extract for best tasting results.
  • all-purpose flour- All-purpose flour is the main dry ingredient in this cookie recipe.
  • baking soda– Baking soda helps the cake rise.
  • kosher salt– Kosher salt is a coarse salt commonly used in cooking and baking.
  • Oreo Cookies– Find Oreo Cookies in the cookie isle of the grocery store.
  • powdered sugar– Also referred to confectioners sugar. You’ll use this sugar to make the icing.
  • heavy cream– Heavy cream is used to help make the icing for the cake.

    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.
