If you grew up with petit beurre biscuits in the pantry, you already know why this cake works. It’s simple, it slices neatly, and it tastes like something you’d actually make again instead of bookmarking and forgetting. This is my go-to no-bake biscuit cake when I want clean layers, a soft creamy center, and a thin Nutella top that sets like a glossy finish.
It’s not fancy, and that’s the point. The biscuits drink just enough milk to turn tender without going soggy, the mascarpone cream holds its shape, and the Nutella layer brings everything together. After two hours in the fridge, it cuts into proper squares and stays stable on a plate.
What this cake is (and what it isn’t)
This is a no-bake cake made by layering tea biscuits (petit beurre) with mascarpone whipped cream, then finishing it with a Nutella topping. There’s no sponge, no oven, and no gelatin. The structure comes from:
- the biscuits softening as they chill
- the whipped mascarpone cream setting cold
- the Nutella firming slightly on top
If you’ve ever made biscuit cake or refrigerator cake, this sits in that family—just a little more “grown up” because mascarpone gives the cream a richer, less sugary taste.
Ingredients overview
Petit beurre biscuits (tea biscuits)
These are the backbone. They’re dry enough to soak up milk quickly and become cake-like after chilling. Any plain tea biscuit works, but petit beurre is ideal because it stays tidy and gives clean layers.
What to look for: plain, crisp biscuits without a strong vanilla coating or thick sugar crust.
Substitution notes: digestive-style biscuits can work, but they soften differently and may crumble more when slicing.
Milk
Milk is the quick “soak” that turns biscuits into something sliceable. The key is brief dipping—not bathing them. Too much milk and the layers slide; too little and the cake stays dry.
Tip: use a shallow bowl so you can dip fast and keep the rhythm going.
Mascarpone
Mascarpone makes the cream thick and stable. It also balances sweetness and gives that soft dairy flavor that doesn’t taste like frosting.
Important: mascarpone needs to be cold, but not rock-hard. If it’s extremely stiff straight from the fridge, let it sit 5 minutes so it blends smoothly.
Powdered sugar
Powdered sugar dissolves instantly and keeps the cream smooth. You don’t need much because Nutella on top adds sweetness too.
Heavy whipping cream (sweet cream)
This is what makes the mixture light. Once whipped with mascarpone, it holds layers nicely and doesn’t leak. The cream must be cold—like properly cold—so it whips fast and stays stable.
Avoid: “light” cream or pouring cream. They usually won’t whip the same way.
Nutella
Nutella is the finishing layer. When melted gently, it spreads easily and sets into a thin, shiny top. If you microwave it too aggressively, it can turn thick and grainy, so a steam bath is the safest method.
Tools that make this easier
- A hand mixer or stand mixer (you can do it by hand, but it’s a workout)
- A baking dish (glass or ceramic is perfect)
- A shallow bowl for the milk
- A small saucepan + heatproof bowl for the double boiler
- A spatula for neat layers
Step-by-step instructions
1) Whip the mascarpone cream
Add the mascarpone, powdered sugar, and cold heavy cream to a mixing bowl. Start mixing on a lower speed for a few seconds so it doesn’t splash, then go up to high speed.
You want a cream that’s thick, smooth, and holds its shape. Stop as soon as it reaches that point. Overwhipping happens quickly once it’s thick—if you push it too far, it can turn grainy.
How I test it: lift the beaters—if the cream forms a firm peak that doesn’t slump, it’s ready.
2) Divide the cream into three portions
This isn’t about being perfect; it just helps keep the layers even. When you eyeball it, the first two layers often end up too thick and you’re scraping the bowl for the top.
3) Start layering: biscuits → cream → repeat
Pour milk into a shallow bowl. Take one biscuit at a time and dip it briefly—a quick in-and-out. Then place it in the dish to form the first layer.
Once the bottom is covered, spread one portion of cream evenly across the biscuits. Keep it level, especially around the edges, because clean edges help the cake slice nicely later.
Repeat the layers until you’ve used everything. The top layer should be cream.
Layering note: if your dish is slightly bigger and you have gaps, you can break a biscuit to fill spaces. Try to keep the surface mostly even so the cream doesn’t sink into holes.
4) Melt the Nutella gently and pour it on top
Set up a double boiler (steam bath): a small saucepan with a little water, and a heatproof bowl sitting over it (the bowl should not touch the water).
Warm the Nutella just until it loosens and becomes pourable. Then pour it over the top cream layer and spread gently.
Go slow: if you drag the spoon hard, you can mix Nutella into the cream instead of creating a clean top layer.
5) Chill, then slice
Refrigerate the cake until it’s set. Once chilled, slice into squares with a sharp knife. For super clean cuts, wipe the knife between slices.
Tips that actually help (from making this more than once)
Keep everything cold for the cream step
Cold cream whips faster and holds. If your kitchen is warm, chill the bowl for 10 minutes. It makes a difference.
Don’t soak the biscuits too long
A quick dip is enough. If the biscuit feels like it’s starting to bend in your fingers, it’s already too wet.
Smooth layers = clean slices
Take an extra minute to level the cream. It’s the difference between a “homemade but neat” square and something that slides around.
Make it the night before if you want perfect texture
Two hours works, but overnight gives the biscuits the best cake-like texture.
If your Nutella looks too thick
Warm it a little longer over steam, stirring gently. Don’t crank the heat—slow warming keeps it glossy.
Serving and storage
- Serve cold straight from the fridge.
- Store covered in the refrigerator. The texture stays best for a couple of days.
- If you’re stacking pieces on a plate, separate with parchment so the Nutella top stays pretty.
Frequently asked questions
Can I make this as a dessert in cups?
Yes. Layer dipped biscuit pieces and cream in cups, then spoon Nutella on top. Chill the same way. It’s easier for serving and still looks great.
Can I use cream cheese instead of mascarpone?
You can, but the flavor is tangier and the texture is slightly heavier. If you do, mix it well so there are no lumps before whipping.
Why did my cream turn grainy?
Most often: overwhipping. Stop as soon as it holds peaks. Also make sure mascarpone isn’t too stiff or clumpy when you start.
No-Bake Biscuit Cake (Petit Beurre Cake) with Mascarpone Cream and Nutella
Ingredients
- 200 g petit beurre biscuits tea biscuits
- 150 ml milk
- 250 g mascarpone
- 2 tbsp powdered sugar
- 400 ml heavy whipping cream sweet cream, cold
- 3 tbsp Nutella
Instructions
- In a mixing bowl, beat the mascarpone, powdered sugar, and cold heavy whipping cream together on high speed until thick and smooth. Do not overwhip.
- Divide the cream mixture into 3 portions for even layering.
- Pour the milk into a shallow bowl. Dip each biscuit briefly in milk and arrange a layer in a baking dish. Spread one portion of cream over the biscuits. Repeat the layers until all biscuits and cream are used, finishing with a cream layer on top.
- Melt the Nutella over a double boiler (steam bath) until pourable, then pour and spread it gently over the top cream layer.
- Refrigerate for 2 hours. Slice into squares and serve cold.
Notes
- Dip biscuits quickly (in-and-out). Soaking too long can make the layers soft and unstable.
- For cleaner slices, chill longer (overnight is ideal) and wipe the knife between cuts.
- Keep the cream and mascarpone cold for best whipping results.
