Oreo cakes

It’s been a while, Oreo… it’s been a while. The last time I posted an Oreo recipe was at the beginning of this year, with my Oreo millionaires, and quite frankly, I am disappointed in myself. I love Oreos, and they are such a world-renowned biscuit that I really should be using them far more often.

They’re one of those biscuits that just work in baking. Chocolatey, creamy, crunchy, nostalgic and universally loved. I’ve done a fair few Oreo recipes over the years and I absolutely don’t plan on stopping any time soon, but I really did leave it far too long before posting another proper Oreo showstopper. This one felt overdue.

More Oreos

My Oreo drip cake has always been one of the most popular cakes on my blog, and even though it’s three years old now, it still gets made all the time. That told me everything I needed to know, people really love Oreos in cake form.

I personally love an Oreo. I know some people don’t understand the hype, but I’m firmly in the “give me all the Oreos” camp. There are so many flavours now too, original, double stuff, mint, golden, and while I am eternally jealous of America and their endless Oreo options, I’m perfectly happy with what we can get here in the UK.

The best part is that pretty much any Oreo works in this recipe. You can switch the flavour to suit whatever mood you’re in or whatever you have in the cupboard. I went with classic Oreos because you truly can’t beat them, and I always seem to have a stockpile lurking somewhere in my kitchen.

Sponge

For the sponges, I decided to keep things classic with a chocolate cake. Three layers, rich but not too heavy, and sturdy enough to hold up all that buttercream. It’s the same style of sponge I use in cakes like my Nutella cake, and it’s one I trust completely for layer cakes.

The cocoa powder gives a deep chocolate flavour without making the sponge dry, and the light brown sugar keeps everything moist and soft. Once baked, the sponges are fluffy but strong, exactly what you want when you’re stacking three layers and adding generous amounts of frosting.

If three layers feels a bit much, you can absolutely turn this into a two-layer cake by removing a third of the ingredients. It’ll still look impressive, just slightly more manageable, although personally, I’ll always vote for three.

Buttercream

The Oreo buttercream frosting is a classic American buttercream, made extra special with plenty of crushed Oreos mixed straight in. And yes… before anyone says it… it is sweet. It’s butter, sugar, and Oreos. That’s the point. If you don’t like sweet cakes, this probably isn’t the one for you.

I blitz the Oreos into a fine crumb and never remove the filling. Honestly, I don’t see the point. It’s fiddly, time-consuming, and the filling is part of what makes an Oreo an Oreo. It adds flavour, texture, and richness to the buttercream, so it stays exactly where it is.

For piping, I always recommend using a jumbo round piping tip. Anything smaller risks getting blocked by Oreo crumbs, which is a fast track to frustration. Trust me — it’s not worth it. The round tip gives those neat, uniform blobs that my roommate lovingly refers to as “buttercream poops”, and I won’t lie… I kind of love them. They’re simple, symmetrical, and incredibly satisfying.

Decoration

Decorating this cake is where the fun really begins. I kept it fairly simple, but bold because when you’re working with Oreos, you really don’t need to overthink it.

I used the remaining buttercream to pipe blobs all around the top edge of the cake, then topped each one with a whole Oreo. Yes, it makes the cake tall. Yes, it makes it dramatic. And yes… that’s exactly how I like it. The height just adds to the whole showstopper feel.

Everything about this cake is satisfyingly round, round cake layers, round buttercream blobs, round Oreos and it just works visually. If you want to take it a step further, you can drizzle over some melted chocolate for extra indulgence, or sprinkle Oreo crumbs over the top for texture. Either way, it’s a cake that looks as good as it tastes.
