Most black forest desserts turn into soup. One minute the cake looks impressive, the next the layers slide apart and the cream weeps into a pink puddle. This black forest cake with nutella avoids that because it leans on crisp cocoa biscuits instead of sponge, and the whole thing sets into clean slices only after a long chill.
The mechanics are simple. You build biscuit sandwiches with Nutella, layer them with a mascarpone cream and a thickened sour cherry filling, then let time do the rest. The biscuits absorb moisture from the milk, cream and cherries until they soften into a cake-like layer. What sounds like a shortcut actually depends on three details.
Three Things That Decide If It Works
The cherry filling must be completely cold. If it is even slightly warm when it hits the white cream, the cream melts and the layers lose their structure. Cook the cherries first, thicken them with cornstarch, then leave them alone while you do everything else.
The biscuits need a quick dip, not a bath. A brief pass through cold milk adds just enough moisture to help them soften later. Hold them under too long and they disintegrate before the cake comes together. The softening happens gradually in the fridge as the biscuits pull moisture from the fillings.
The cream needs soft peaks, then you stop. Add the mascarpone and only mix until the cream is thick and uniform. Overwhipping turns it grainy and eventually buttery. The mascarpone stabilizes the whipped cream, which is why this version slices better than one made with plain whipped cream.
Ingredient Choices That Matter
Cocoa biscuits with a dry, snap-like texture work best here. They hold their shape through the milk dip but soften fully during chilling. Petit beurre cocoa or similar rectangular tea biscuits are easy to arrange in a pan.
Nutella provides sweetness and a slight hazelnut note between every biscuit pair. The amount is flexible. A thin scrape keeps the cake less sweet, a thicker layer makes the chocolate presence stronger and helps the sandwiches stay together. Any chocolate hazelnut spread works the same way.
Sour cherries carry the signature black forest flavour. Frozen ones release plenty of juice as they cook and are usually picked at peak ripeness. Jarred sour cherries are fine too, but drain most of their liquid so the filling does not get too loose. Sweet cherries will change the character, giving a milder result closer to a standard chocolate cherry dessert.
Mascarpone gives the cream body without gumminess. Cream cheese can replace it in a pinch, but cream cheese is tangier and softer, so the final set may be less firm. Use full-fat mascarpone for the cleanest texture.
Building the Layers Without Rushing
Start with the sour cherry layer because it needs the longest cooling time. Put the cherries, sugar and lemon juice in a saucepan over medium heat. Within a few minutes the cherries soften and the juices collect. Mix the cornstarch with a little cold water first, never add it dry. Pour the slurry into the hot cherries and stir. The liquid turns glossy and noticeably thicker almost immediately. Once it coats the back of a spoon, take it off the heat. Let it cool uncovered, stirring once or twice, until it reaches room temperature.
For the cream, use heavy cream straight from the fridge. Cold cream whips more reliably and traps air better. Whip it with powdered sugar until trails form in the surface but the peaks still flop over when you lift the whisk. Add the mascarpone and vanilla, then mix briefly. The mixture should be thick enough to hold its shape but still smooth. Split it in half so both layers come out even.
Assemble in a pan around 20 x 18 cm, roughly 8 x 7 inches. Spread one side of a biscuit with Nutella and press another biscuit on top to make a sandwich. Dip that sandwich in milk for a second per side, no longer, then place it in the base of the pan. Continue until the bottom is covered, breaking or trimming biscuits if needed to fill gaps.
Spread half the cream over that first layer and level it. Spoon the cooled cherries on top and spread them gently so the red layer stays distinct. Build a second round of Nutella biscuit sandwiches, dip each quickly in milk, and arrange them over the cherries. Press down lightly with your palms. Finish with the remaining cream and smooth the top.
Now the waiting starts. Refrigerate for at least six hours, but overnight is better. During that time the biscuits absorb moisture and soften, the cream sets, and the layers bond. Cutting early is the most common reason the cake collapses.
Fix-It List
Cherry filling too runny: Cook it a little longer after adding the cornstarch. The thickening becomes more obvious as it cools, so let it reach a jammy consistency in the pan rather than hoping it sets later.
Cream too soft: Chill the bowl and beaters for ten minutes before whipping. If the cream already looks grainy, you overwhipped it. Fold in a splash of cold cream by hand to smooth it out, or start again if it has separated.
Biscuits falling apart in milk: Dip faster. Count one second per side. The goal is surface moisture, not saturation.
Layers sliding when slicing: Chill longer. Use a sharp knife and wipe it between cuts. Cut straight down without sawing.
Too sweet: Reduce the sugar in the cherry layer slightly or use a thinner spread of Nutella. The cream itself is not very sweet, so most of the sugar comes from those two components.
Storage and Making Ahead
This cake stores well because the chilled structure gets firmer with time. Cover the pan tightly with plastic wrap and keep it in the refrigerator for up to three days. The cream stays stable thanks to the mascarpone, though the biscuits soften further each day. For general cold storage guidance, see the FoodSafety.gov cold storage chart.
Make the cherry filling up to two days ahead and refrigerate it in a sealed container. Wait to assemble until the day you plan to serve, since the cake needs its long chill. Freezing is not recommended once assembled because thawing causes the cream to release liquid and the texture to turn watery.
Can You Use a Different Pan?
Yes. The exact dimensions matter less than the number of layers you plan to build. A smaller pan gives higher layers, a larger pan spreads everything thin. Adjust how many biscuit sandwiches you make so each layer covers the surface without large gaps. Just remember the biscuit count changes, not the amount of cream or cherry filling.

What If Fresh Cherries Are Out of Season?
Frozen sour cherries are the most reliable option year-round and the recipe works exactly as written. Look for pitted frozen cherries to save time. Jarred cherries work but drain them fully and taste the filling before assembling. Some jarred versions pack extra sugar, so you might reduce the added sugar.
Why Is My Top Layer Sticking to the Wrap?
Plastic wrap pressed directly onto fresh cream always sticks. If you cover the pan before chilling, lay a sheet of parchment over the surface first, then wrap loosely. Once the cake has chilled overnight, the top is firm enough that light plastic contact leaves only small marks, which you can cover with grated chocolate.
Can You Skip the Nutella?
You can swap it for another firm spread such as chocolate almond spread or dark chocolate ganache. The spread adds flavour but also acts as a seal between biscuits, keeping them from turning soggy too fast. Skipping it entirely gives a drier, less chocolate-forward result, so choose something sticky and spreadable if not using Nutella.

Black Forest Cake with Nutella
Ingredients
Biscuit Layers
- 250 g cocoa biscuits
- Nutella as needed, about 1 teaspoon per biscuit sandwich or to taste
- 100 ml milk for dipping
White Cream Filling
- 400 ml heavy cream 35% fat cold
- 250 g mascarpone cheese
- 2 tablespoons powdered sugar
- 1 teaspoon vanilla extract
Sour Cherry Layer
- 300 g sour cherries pitted, fresh or frozen
- 2 tablespoons sugar
- lemon juice juice of half a lemon
- 2 teaspoons cornstarch
- cold water a little, for mixing with the cornstarch
Decoration
- grated or chopped chocolate as needed
- sour cherries as needed
Instructions
- Place the sour cherries, sugar, and lemon juice in a saucepan. Cook for a few minutes until the cherries release their juices.
- Mix the cornstarch with a little cold water, then add it to the cherries and stir. The filling thickens quickly. Once thickened, remove it from the heat and leave it to cool completely.
- In a large bowl, whip the cold heavy cream and powdered sugar until soft peaks form. Add the mascarpone and vanilla, then mix briefly until the filling is thick and creamy. Divide it into two equal portions.
- Spread a cocoa biscuit with about one teaspoon of Nutella and top with another biscuit. Repeat to make enough biscuit sandwiches to cover the base of a 20 x 18 cm pan. Briefly dip each sandwich in the milk and arrange them in the pan.
- Spread half of the white cream filling over the biscuits and smooth the surface. Spread the completely cooled sour cherry filling over the cream.
- Make another layer of biscuit sandwiches by spreading Nutella between pairs of cocoa biscuits. Briefly dip each sandwich in the milk and arrange them over the sour cherry filling.
- Spread the remaining white cream filling on top and smooth the surface. Refrigerate the cake for 6 to 8 hours, preferably overnight.
- Decorate with grated or chopped chocolate and sour cherries, then slice and serve.
Notes
Mix the cornstarch with cold water before adding it to the cherries. The filling thickens very quickly, so watch it closely and cool it completely before assembling.
Do not overwhip the heavy cream. Once soft peaks form, add the mascarpone and mix only until thick and creamy.
Dip the biscuit sandwiches in milk only briefly so they do not fall apart. They will soften further as they absorb moisture from the filling while the cake chills.
