Frequently Asked Questions

What is Oreo Cake?
Oreo Cake is a soft, fluffy white cake mixed with crushed Oreo cookies and topped with a sweet homemade buttercream frosting. Think of it as a sheet cake version of cookies-and-cream ice cream- every bite has those signature Oreo crumbs swirled throughout!

Do I need to use a boxed cake mix?
This recipe calls for a standard white cake mix, which keeps things easy and consistent. You can absolutely use your favorite homemade white cake recipe if you prefer, but the cake mix saves time and still delivers great flavor and texture.

How do I make Oreo Cake dairy-free?
It’s easy to make this Oreo Cake without dairy. Swap the butter in the frosting for a plant-based butter and use a non-dairy milk like almond, soy, or oat milk. Oreos themselves are dairy-free, so you don’t have to change anything there. If you’re using a cake mix, double-check the box to make sure it doesn’t call for milk or butter- most can be made with oil, water, and eggs. And of course make sure the mix itself doesn’t contain dairy!

Can I use different flavors of Oreos?
Yes! This recipe works with classic Oreos, but you can have fun experimenting with seasonal flavors or varieties like Golden Oreos, mint, or birthday cake Oreos. Each one gives the cake a unique twist.

How should I store Oreo Cake?
Once frosted, Oreo Cake should be kept covered at room temperature for up to two days, or in the refrigerator for 3-4 days. If you want to make it ahead, you can bake the cake, wrap it tightly in plastic wrap, and store it in the freezer for up to two months before frosting.

Can I make Oreo Cake in advance for a party?
Yes, this is a great make-ahead dessert! Bake the cake a day before your event, let it cool completely, and store it tightly covered. Frost and add the crushed Oreos on top right before serving for the freshest look and crunch.
