This is the kind of cake I make when I want something that looks “finished,” but I don’t feel like switching the oven on. It’s simple: Oreo crust on the bottom, a creamy Nutella cocoa layer in the middle, and a softer top layer with broken Oreos for texture.

It also happens to be a great make-ahead dessert. I usually build it in the afternoon, forget about it for a few hours, then decorate right before serving. If you’ve got a 20 cm pan and a fridge, you’re set.

What this cake tastes like (and how it sets)

This is a no-bake cake, but it slices cleanly once it’s chilled long enough. The structure comes from whipped cream + mascarpone. Mascarpone gives that thick, creamy texture without needing gelatin. The chocolate layer is denser because of the Nutella and cocoa, and the top layer is slightly lighter and speckled with Oreo pieces.

If you’ve ever had a soft cheesecake filling and wished it had Oreos and Nutella in it, that’s the vibe.

Ingredients (with a quick breakdown of what each one does)

Oreo crust

200 g Oreo cookies
These make the base and give the crust that classic chocolate cookie bite.
50 g butter (melted)
Butter is the glue. Once it chills, it firms up and holds the crumbs together.
2 tbsp milk
This is the small trick that makes the crust easier to press and less crumbly when slicing.

Crust note: I use the whole Oreo (cream and all). It binds nicely and tastes better than scraping the filling out.

Chocolate filling

200 ml heavy cream (sweet whipping cream, ~35%)
Whipped cream gives volume and helps the layer hold its shape.
250 g mascarpone
The thick base of the filling. It makes everything creamy and stable.
1 tbsp powdered sugar
Just enough sweetness to balance the cocoa without making it overly sweet.
2 heaping tbsp Nutella
The main flavor. “Heaping” is important here—don’t be shy.
1 tbsp cocoa powder
Cocoa deepens the chocolate flavor so it doesn’t taste only like hazelnut spread.

White filling

200 ml heavy cream (sweet whipping cream, ~35%)
250 g mascarpone
1 tbsp powdered sugar
7–8 Oreo cookies (broken into pieces)
I like bigger chunks rather than finely crushed crumbs, so you get texture.

Equipment you’ll need

20 cm round pan (springform makes life easier, but not required)
Food processor or a zip bag + rolling pin for crushing Oreos
2 mixing bowls
Hand mixer or stand mixer
Spatula
Spoon or flat-bottom cup for pressing the crust

Step-by-step instructions (exactly how I make it)

1) Make the crust

Crush or grind the 200 g Oreos until you have fine crumbs. A few tiny chunks are fine, but aim for mostly sandy texture.
Add 50 g melted butter and 2 tbsp milk. Mix until the crumbs look evenly moistened—like wet sand that holds when you squeeze it.
Press the mixture into a 20 cm pan, firmly and evenly. I press the bottom first, then pack the edges.

Put the pan in the fridge while you make the filling.

My crust test: Press with your fingers—if it stays put and doesn’t stick to you too much, it’s ready.

2) Make the chocolate filling (and chill it)

In a bowl, mix together:
- 250 g mascarpone
- 1 tbsp powdered sugar
- 2 heaping tbsp Nutella
- 1 tbsp cocoa powder

In a separate bowl, whip 200 ml heavy cream until thick.
You want it to hold soft-to-medium peaks. If it’s still runny, the layer won’t set well.
Add the whipped cream into the mascarpone mixture and mix briefly, just until combined.
Don’t overmix—once it’s smooth and uniform, stop.

Spread the chocolate filling over the crust. Smooth the top.

Refrigerate for 1 hour so the chocolate layer firms up before adding the next layer.

Why the 1-hour chill matters: If you skip it, the top layer can sink into the chocolate layer and you’ll lose that clean two-layer look.

3) Make the white filling (with Oreo pieces)

In a bowl, beat together 250 g mascarpone and 1 tbsp powdered sugar until smooth.
In another bowl, whip 200 ml heavy cream until thick (again, soft-to-medium peaks).
Combine whipped cream with the mascarpone mixture. Mix only until blended.
Break 7–8 Oreos into pieces (I do a mix of small chunks and medium chunks) and fold them in. A quick, gentle mix is enough.

Spread the white filling over the chilled chocolate layer and smooth the top.

4) Chill the whole cake

Refrigerate for 3 hours.

If you can chill it longer (like overnight), it slices even cleaner. But 3 hours is the minimum I stick to if I’m serving it the same day.

5) Decorate (simple ideas)

Decorate however you like:

Oreo halves around the edge
A few crushed Oreos sprinkled on top
Melted Nutella drizzled over the surface (10–15 seconds in the microwave helps)
Whipped cream piping if you’re feeling fancy

I usually keep it simple: drizzle Nutella and press a few Oreos on top. It looks like a lot of effort with almost no effort.

Tips that actually help (things I learned after making it a few times)

Use cold cream, but don’t freeze your bowl

Cold cream whips better. Straight from the fridge is perfect. If your kitchen is very warm, a chilled bowl helps, but don’t overdo it—icy cold bowls can make mascarpone seize if you mix it too aggressively.

Don’t overwhip

If you whip the cream until it looks grainy or starts turning buttery, the filling texture won’t be as smooth. Stop when it holds peaks and looks thick but still creamy.

Mascarpone doesn’t like being overmixed

Mascarpone can go from smooth to weirdly loose if you beat it too long (especially if it warms up). Mix just until smooth.

Press the crust firmly

A loose crust is the only thing that can ruin the slice. Pack it down well. I use the bottom of a glass and really press the edges.

Clean slices trick

Dip a knife in hot water, wipe it dry, slice. Repeat. It makes the layers look neat even if you’re impatient.

Storage

Fridge: Keeps well for 3–4 days in a covered container.
Freezer: You can freeze it, but the Oreo bits in the top layer soften a bit once thawed. Still tasty, just a different texture. If freezing, wrap well and thaw overnight in the fridge.
