Oreo Drip Cake!

A 3-layer chocolate cake, with Oreo buttercream, a chocolate drip, and even more Oreos make a delectable & showstopping Oreo drip cake!

Oreo favourites
One of my dad’s colleagues recently had their last day at work, and because she has been one of my most enthusiastic taste testers (and just the loveliest person ever), I wanted to bake something properly special. Naturally… that meant a drip cake. You know I can never resist making a big showstopper, especially for an occasion.
And even though I didn’t actually get a slice of the finished cake (tragic, I know), I did “accidentally” taste-test several spoonfuls of the buttercream during decorating. Purely for quality control, obviously. The reviews from the office were glowing… apparently it disappeared within minutes!
I’ve been itching to make another Oreo bake for a while, and turning it into a full drip cake felt perfect. The Oreo buttercream alone is enough to convert anyone.
The sponge
I used the same idea for the cake from my Salted Caramel Drip Cake and my Biscoff Drip Cake, just using less self-raising flour, and adding in some cocoa powder to make it chocolatey and rich. The layers bake up soft, moist and sturdy enough to build a tall cake without collapsing, exactly what you want for a drip cake.
- Butter – unsalted butter or baking spread at room temperature is the best way to go for the perfect fluffy sponge
- Sugar – for most of my sponge recipes I use light brown sugar but you can use caster, golden caster or dark brown sugar
- Eggs – 8x medium eggs roughly translate as 400g of egg weight, most of my recipes run on medium eggs unless specially stated otherwise
- Flour – self-raising flour will provide the rise needed for three beautiful tiers of delicious sponge
- Cocoa powder – I replace 75g of flour with cocoa powder to give that rich delicious chocolate flavour throughout the sponge as well as the buttercream frosting
- Baking powder – an optional extra to provide a lighter texture to the sponge, many have said they don’t like adding the extra as it is already in the flour, I will leave that choice to you.
- Milk – If you’re mixture is slightly thicker than desired you can use whole milk to gradually loosen the mixture, use one tbsp at a time!
I know three-layer cakes often look a bit intimidating, but they truly aren’t any more difficult than two layers. They just LOOK ten times more impressive, the wow factor alone makes all the effort worth it and the taste matches the presentation perfectly.
Oreo buttercream
For the frosting, I stuck with the same Oreo buttercream recipe I use for my Oreo cupcakes because it’s simply perfect, fluffy, sweet, creamy, and packed with Oreo biscuit flavour. I used 300g of butter and 650g of icing sugar, then blitzed an entire pack of Oreos into a fine crumb and mixed them in. It makes enough to fill the layers, coat the outside, pipe on top, and still have a little leftover to sneak spoonfuls of.
The texture is dreamy. There’s something about adding the crushed biscuits that makes it so easy to smooth around the cake, I honestly don’t know why, but I’m not questioning it. This will boost the presentation of your cake from standard to spectacular, a smooth coating of Oreo buttercream really will look like an expensive showstopper by the time you’re finished.
The drip
I tried a new method of doing the drip on this cake, by using oil. I’ve seen people having a few problems making the ganache drip as ganache can be quite temperamental, so after reading up on the oil method I had to try it.
You only use between 1-2tbsp of oil for this amount of chocolatey, and you can’t detect it once its added. It just makes the chocolate runnier, and easier to use, whilst keep its shine. You can just use melted chocolate, but often this can be harder to use as its thicker, and it well set very solid. I’m surprised I didn’t eat some of it myself, but I resisted to make sure it look better.
If you wanted to use a ganache however you can, simply use 150g of dark chocolate and 150g of double cream! (Read about the ganache drip here… Caramac Cake)
Decoration
Once the drip had set slightly, I piped little swirls of Oreo buttercream around the top and added whole Oreos for decoration. A sprinkle of crushed Oreos finishes it off, because when you think you’ve added enough Oreos… always add a few more.
This cake is bold, chocolatey, and cookies-and-cream heaven. It’s fun to make, fun to decorate, and an absolute delight to present. I adored every minute of making this one, and the finished result brought so many smiles. I hope you love it as much as my dad’s colleagues did!
Two tier versions
I get asked all the time on my blog and social media if this cake can be made smaller, perfect for a more intimate family celebration or birthday. The good news? Absolutely! With a few simple tweaks, you can create a slightly smaller Oreo cake that’s just as delicious and impressive.
For a smaller version, I recommend using two 8″cake tins. You can adjust the ingredients as follows:
- 300g butter
- 300g sugar
- 245g flour
- 55g cocoa powder
- 1.5 tsp baking powder
- 6 medium eggs
- 3 tbsp milk
Baking time may increase slightly, around 5–10 minutes longer, depending on your oven and tin. For the decoration, you can use roughly two-thirds of the original buttercream and toppings, which still makes for a gorgeous, indulgent cake.
This scaled-down version is perfect for smaller gatherings and still delivers all the Oreo, chocolate, and cookies-and-cream goodness of the full-sized drip cake. It’s a flexible recipe that adapts beautifully for any celebration
Tips & tricks
- You obviously don’t have to make straight edged buttercream if you don’t want to, but I just like the look of it. You can slather it on, and it’ll still taste damn delicious.
- However, if you do want to make it like this, I seriously recommend using a metal scraper for the decoration of the buttercream, and the disposable piping bags.. I wouldn’t be anywhere without them.
- All of the decorations are completely optional , but I love this style of cake.
- This cake will last in an airtight container for 3 days.

Oreo Drip Cake!
Ingredients
Cake Ingredients
- 400 g unsalted butter/baking spread
- 400 g light brown sugar
- 400 g eggs (roughly 8 medium)
- 325 g self raising flour
- 75 g cocoa powder
- 2 tsp baking powder
- 4 tbsp whole milk
Oreo Buttercream Frosting
- 300 g unsalted butter (room temp - not baking spread)
- 650 g icing sugar
- 154 g Oreos (1 pack)
- 2-5 tbsps whole milk
Decoration
- 175 g dark chocolate
- 1-2 tbsps vegetable/sunflower oil
- Oreos
- crushed Oreos
Instructions
For the Cake!
- Heat the oven to 180ºc/160ºc fan and line three 20cm/8inch cake tins with baking parchment – leave to the side.
- In a stand mixer, beat together the butter and light brown sugar until light and fluffy. Add in the flour, cocoa powder, beaten eggs, baking powder and beat again briefly till combined – try not to over beat the mixture! If its really thick, mix in the whole milk to loosen.
- Divide the mixture between the three tins and smooth it over – bake for 25-30 minutes until a skewer comes out clean when poked, and when the cake springs back.
- Once baked, leave the cake to cool in the tin for 10 minutes, and then remove and leave to cool fully on a wire rack. If the cake has domed slightly, leave the cake to cool upside down to flatten it slightly.
For the Decoration!
- In a stand mixer, beat the room temperature butter with an electric mixer until it is smooth and loose and then beat in the icing sugar 1/3 at a time until its fully combined. Keep beating the buttercream for a few minutes so it starts to get fluffier and lighter.
- In a food processor, blitz the packet of Oreo’s to a fine crumb, and add into the buttercream. Beat the buttercream again till smooth, and use the Milk to loosen it to a smooth consistency.
- Once the cakes are cooled, put the first layer on the serving plate spread some of the buttercream onto the top of the first layer, add the second cake on top, and then top again with some of buttercream and then add the final sponge layer. Only use about 2 tbsps of buttercream per layer so that you have enough to decorate with!
- With the leftover buttercream, as you can see, I covered the sides (and top) too! Do a first layer of around the edge and top using a large metal scraper and refrigerate for 10 minutes. Repeat again with a slightly thicker layer of buttercream.
- I slather it on all over using an off -set spatula, and then run the metal scraper round until its smooth. If the Oreo’s were blitzed to a really fine crumb like you need, the buttercream can still be smooth around the edges even though there is biscuit in the mix!
- Once finished, melt the dark chocolate in a heat proof bowl until melted. Add in 1tbsp of oil and beat till smooth, continue to add oil till you get to a drippy consistency. I used 1+1/2 tbsps total. Using disposable piping bags, pipe it round the edge of the cake, edging over slight bits to create the drip.
- You don’t need to use too much per drip as it’ll drop quite far down by itself! Fill in the top in with the rest of the chocolate so the top is also covered. Refrigerate the cake for about 15 minutes.
- Using some left over buttercream, pipe little rosettes of buttercream onto the top and add a whole oreo – sprinkle on some crushed oreos and huzzah! You’re done! Enjoy!

- All of the decorations are completely optional – but I love this style of cake! To make a smaller version of the cake, use:
- Two 8″cake tins
- 300g butter
- 300g sugar
- 245g flour
- 55g cocoa powder
- 1.5tsps baking powder
- 6 medium eggs
- 3 tbsps of milk
- And it might take an extra 5-10 minutes to bake and use 2/3 of the decoration recipes!
- This cake will last in an airtight container for 3 days!






Hi is the 400g of eggs in there shells or not please
I have made this cake twice now, once for my son’s 8th birthday and once for my daughter’s 17th birthday. Both times went down an absolute treat! Would definitely recommend for any Oreo lover!
Hi. I followed the recipe best I could but my cakes came out really flat and not risen well at all. Any idea why? I used springform tins if the makes any difference. Thanks.
This can be a few reasons such as over mixing the cake mix, cold eggs, or opening the oven too soon! x
Hi Jane, i have just made this gorgeous oreo drip cake!!! and its definitely a WOW cake!! i made it for my daughters 19th birthday which is tomorrow (she scanned the books we have of yours and then looked on your website). I have one question; do i need to store it in the fridge over night? I don’t actually have a container tall enough to cover it and i think cakes that have been in the fridge the sponge becomes hard. but the uk is also warm right now so any advice on how to store it would be super helpful. Thank you xx
Hiya! Drip cakes can be stored in the fridge if they haven’t been cut into as they are completely covered in buttercream. Once cut into, and the sponge is on show, the fridge should be avoided as it’ll dry the cake out. The cake needs to come to room temp before eating as well x
Hi Jane, I have your recipe book, with what I believe is the same cake, but it doesn’t have the milk in the recipe. Does the milk have a big impact on the texture of the cake?
Just made this as a two layer and it turned out perfectly, with the drip would it also work with other chocolate? If so would it be the same ratio chocolate/oil?
The ‘lighter’ or less cocoa content the chocolate, the less oil it needs! x
I’ve done this cake previously and it went down a treat!
I would like to do it in a 6 inch. the measurements are going down, some a little awkward to figure out the exact measurements but im sure ill get there. But not the eggs, can you confirm how many eggs will be needed please?
Hi Jane, ( im sure u can remember me, holly ) i need to make another 6 tier cake for my twins birthday and I was wondering what carrier should I use and also can I use just 1kg butter for the buttercream?
If I omitt the oreos in the buttercream I don’t have a blender, will it change the amount of ingredients for it?
Corinna
Yes, you’ll need to increase the other quantities to make sure all of the cake can be filled and covered – you can try crushing them finely with a rolling pin in a bowl however, it just takes time x
Hi Jane,
Absolutely love this recipe!
Just wondering what the proportions would be for cupcakes (need to make 20-25), for both the cake mix and buttercream?
Thank you!
Hi Jane. I am a big fan of your cheesecakes and cakes. They are the only ones I make for by celebrations. I’ve made this Oreo drip cake and it was a huge hit. This time I need to make a large rectangle cake to be able to slice it in around 25 pieces. Could I use this recipe and make the cake in two 9 x 13 inch tins? Would I need more cake mixture? Cooking time? How much icing?
Thank you.
I made this today for my daughter’s birthday. I’ve never made a drip cake before, I used milk chocolate because she turns her nose up at dark, it worked so well.
This is a delicious recipe and will be hard to beat in future, xx I’d post a photo but I don’t know how to do that.
Hey! I wanted to make a bigger version of this cake in 2 x 12 inch tins and then cut them both in half so i have 4 layers. Should I double the amount of ingredients for both cake and buttercream? what measurements of ingredients should i use?
Thankyou!
