Let’s talk about cakes — more specifically, layer cakes.
I get a lot of questions about easy layer cakes, and I get it.
Food blogs are full of towering, three (or four — or five!) layer cakes, perfectly smooth, decorated with stunning buttercream flowers and beautiful mirror glazes. They are true edible works of art, and should be celebrated as such.
They’re also really intimidating — and as a result, I get a lot of emails from readers asking if I have recipes for easy layer cakes, like from a box mix, or layer cakes that don’t require decorating skills.
This chocolate oreo cake isn’t from a boxed mix, but it IS easy — and because the frosting is filled with chopped up oreos, it’s not supposed to be silky smooth. It is, however, always going to be delicious (which is the most important part of a cake!), only two layers, and it’s easy.
This is the perfect layer cake for people who don’t think they can bake layer cakes!
In fact, it’s one of the first layer cakes I ever made — and the very first one to appear on Bunsen Burner Bakery, all the way back in 2011! It’s about time for a little update with some new photos and new baking tips (but the same great recipe!).
What this cake is:
- heavy on the cream cheese oreo frosting
What this cake is not:
- a work of art
- too hard for you to make
Are you ready? Yes, you are. Let’s go make this delicious chocolate oreo cake!
Chocolate Buttermilk Cake
First up, we have to make the cake. To keep this cake extra moist and chocolatey, we’re using two key ingredients: natural unsweetened cocoa powder and buttermilk.
Natural unsweetened cocoa powder has the most concentrated chocolate flavor, which gives us a super chocolatey cake. We’re also going to toss in some chocolate chips, for some semi-sweet chocolate flavor and a little crunch.
The buttermilk also plays a crucial role, in both the texture and tenderness of the cake . Why is this? It’s time for my favorite subject… kitchen chemistry!
Buttermilk is slightly acidic, and lowering the pH of the batter helps to break down the long strings of gluten from the flour. What happens when we break down gluten? We get a cake that is tender and more moist! Buttermilk also helps to produce carbon dioxide when paired with baking soda, which means… you guessed it… lighter and fluffier cakes.
Cream Cheese Oreo Frosting
I really like pairing buttermilk-based cakes with cream cheese frosting, and who can resist crumbled Oreos? (Certainly not most chocolate lovers!) The added bonus to adding them to the frosting is eliminating any stress over decorating — there’s no need to fret over perfectly smooth frosting!
Making the frosting is easy — beat together the ingredients using a hand or stand mixer.
The crumbled oreos make the frosting a little too thick to pipe, so this is the kind of cake that is perfect to just spread on with a spatula. Whip everything together with a mixer, spread it on the cake, and you’re good to go!
All the cake requires to look extra special are a few dollops of whipped cream and some whole oreos – simple and easy.
How to Assemble a Layer Cake
First things first, wait until your cake is fully cooled! Trying to stack and frost a still warm cake is a recipe for disaster, so wait until everything is fully cooled — several hours is good, waiting overnight is even better if you have the time!
Once your cake layers are fully cooled, you’ll want to start with a crumb coat. This is a thin layer of frosting applied to the side of the cake to hold the cake crumbs down – preventing them from clumping up the frosting along the outside of the cake.
Because there are already cookie crumbs in this frosting it’s not as important, but sometimes cakes are crumbly and it’s frustrating when your cake falls apart into your frosting!
Spread a thick layer of frosting on top of one layer of cake and place the second layer on top. Then spread a thin layer of frosting along the sides of the cake — it’s okay if you can still see the cake peeking through — and a thin layer on top.
Refrigerate for 15 minutes, then add the rest of the frosting to the top and sides until fully covered.
Finish decorating how desired — with additional whole oreos, whipped cream swirls, or drizzles of melted chocolate!
How to Make Chocolate Oreo Cake Ahead of Time
Another reason this is such a great cake? Everything can be made ahead of time! The layers of chocolate cake can be baked days (or even months!) in advance.
Bake up to three days in advance and store in an airtight container, or wrap in aluminum foil and store in a freezer bag in the freezer for up to three months before frosting.
The oreo cream cheese frosting can be made up to three days in advance and stored in the refrigerator. Bring to room temperature for 30 minutes and beat again with a mixer before spreading on the cake.
The entire cake can be assembled and decorated a day (or even two!) ahead of time before serving.
How to Store Chocolate Oreo Cake
Once assembled, the cake must be refrigerated due to the cream cheese in the frosting.
Leftover slices can be stored in the refrigerator for up to a week, ideally wrapped tightly in plastic wrap to help prevent the cake from taking on a stale flavor.
For longer term storage, freeze individual slices of cake upright on a cookie sheet in the freezer. Once frozen solid, wrap the individual slice in a sheet of plastic wrap, followed by a sheet of aluminum foil, and store in a freezer bag for up to 3 months. To thaw, remove from freezer bag and unwrap, and thaw under refrigeration.
Tips and Tricks for Chocolate Oreo Cake
- For perfectly flat, non-domed cakes, use Bake Even Strips (or wet cloths soaked in water and wrapped around the outside of the cake pans).
- Cool cake layers completely before frosting — the frosting will melt if the cakes are even a little warm!
- Short on time? All components of this cake can be made ahead of time. The cake layers can be baked and frozen for up to 3 months. The cream cheese oreo frosting can be made up to three days ahead of time. The cake can be assembled the day before.
- Start frosting the cake with a crumb coat — a thin layer of frosting — which will help hold any crumbs from the side of the cake in place. After 15 minutes in the refrigerator, add an additional thick final outer layer of frosting to the whole cake.
- Store the chocolate oreo cake in the refrigerator.
- To prevent the cut cake from getting stale, wrap leftover slices in plastic wrap or push wax paper against the exposed edge to minimize contact with air.
