A crisp chocolate cookie crust, silky chocolate mousse, and a glossy homemade cherry compote, all layered into one showstopping no-bake dessert. This Black Forest Tart is rich, deeply chocolatey, and just a little dramatic in the best way. I first made it one December when I needed something that looked bakery-fancy but didn't ask me to turn on the oven, and it completely delivered.
If you love fruity, chocolate-forward desserts, you'll want to bookmark my Dark Chocolate Raspberry Truffles and Speculoos Tiramisu while you're here, because they pull the same kind of "how did she do that" energy.The whole thing comes together with simple ingredients and no baking required, just some gentle stovetop work and a patient hour or so in the fridge. The kind of dessert that makes a holiday table look like you hired someone. If you're craving something on the cozier, homier side, my Monster Cookie Brownies have your name on them too.

Cherry Compote
- Cherries , fresh or frozen: These are the heart of the compote. Fresh cherries work beautifully in summer, and frozen cherries are great year-round. Both give you that deep, jammy flavor.
- Granulated sugar : Sweetens the compote and helps it thicken as it cooks.
- Cornstarch : The thickening agent. Whisked with a bit of water first so it dissolves cleanly into the fruit.
Chocolate Cookie Crust
- Chocolate sandwich cookies : Crushed fine, these form the base of the tart. The filling inside the cookies adds a little sweetness and helps the crust stick together.
- Melted butter : Binds the cookie crumbs into a firm, sliceable crust.
Chocolate Mousse Filling
- Chocolate chips or chopped baking chocolate : The base of the ganache and the mousse. Dark or semi-sweet both work well here.
- Heavy whipping cream , divided: Used in two ways. A portion melts with the chocolate to create the ganache, and the rest gets whipped to fold into the filling and top the tart.
- Powdered sugar : Sweetens the whipped cream gently without weighing it down.
How to Make Black Forest Tart
Everything from this no-bake Black Forest Tart comes together in a few clear stages.
Prep the cherries: Remove any pits from the cherries if needed, then chop them into roughly pea-sized pieces. In a small bowl, whisk the cornstarch with about 1 tablespoon of water until smooth.
Cook the compote: Combine the chopped cherries, granulated sugar, and cornstarch mixture in a medium saucepan. Cook over medium heat, stirring frequently, until the mixture thickens to a compote or pie filling consistency. Set aside and let it cool completely.
Make the crust: Crush the chocolate sandwich cookies in a food processor until fine. Pulse in the melted butter, or stir them together in a bowl until the crumbs are evenly coated. For a 10-inch tart pan, use 24 cookies and 4 tablespoons butter. For an 8- or 9-inch pan, use 18 cookies and 3 tablespoons butter.
Press and chill the crust: Press the crust mixture evenly into the bottom and slightly up the sides of the tart pan using a flat-bottomed measuring cup or drinking glass. Freeze for 10 minutes, or refrigerate for 20-30 minutes until firm.
Make the ganache: Place the chocolate and ¾ cup (6 ounces) of heavy cream in a heatproof bowl. Set the bowl over a saucepan with 1-2 inches of simmering water, making sure the bottom of the bowl sits partially above the water, not submerged. Stir frequently until the chocolate is fully melted and the mixture is smooth. Remove from heat.
Seal the crust: Spread a thin layer of the melted chocolate over the chilled crust to create a moisture barrier. This keeps the crust from getting soggy. Refrigerate the crust while the chocolate sets. Let the remaining ganache sit at room temperature until it's cooled but still stirrable.
Whip the cream: In a stand mixer or large mixing bowl, combine the remaining 2½ cups heavy cream with the powdered sugar. Beat on medium speed until frothy, then increase to high speed and beat until stiff peaks just begin to form. Set aside about one-quarter to one-third of the whipped cream for topping and refrigerate it.
Build the mousse: Fold one-third of the remaining whipped cream into the ganache to lighten it. Fold in another third, then the last third, until the mousse is smooth, silky, and evenly combined.
Layer the tart: Spread a thin layer of cherry compote over the sealed crust. Spoon the chocolate mousse evenly over the cherry layer. If you have extra mousse, divide it into small jars with leftover compote for little individual desserts.
Chill to set: Refrigerate the tart for about 1 hour until the filling is fully set and holds its shape when sliced. You can freeze it briefly to speed this up, then move it to the refrigerator before slicing.
Finish and serve: Pipe or spoon the reserved whipped cream over the top of the tart. Spoon remaining cherry compote over each slice just before serving.
Substitutions
- Frozen cherries instead of fresh: Works perfectly. No need to thaw first; just add them to the pan and let them cook down.
- Dark chocolate instead of semi-sweet: Gives the mousse a deeper, more intense flavor. Great if you prefer a less sweet dessert.
- Other chocolate sandwich cookies: Any chocolate wafer-style cookie works for the crust. Thin Mints or chocolate graham crackers are fun variations.
- Store-bought cherry pie filling: In a pinch, you can skip the homemade compote and use canned cherry pie filling. It's sweeter and less tart, but it works.
- Whipped topping (like Cool Whip): Can replace the fresh whipped cream for the topping only, not for the mousse itself, which really needs real heavy cream to set properly.

How to Store This Black Forest Tart
Refrigerator: Cover the tart loosely with plastic wrap or store in an airtight container in the fridge. It keeps well for up to 3-4 days. The crust may soften slightly over time, but the flavors actually get better by day two.
Freezer: You can freeze the whole tart (without the whipped cream topping) for up to one month. Wrap it tightly in plastic wrap and then foil. Thaw overnight in the refrigerator before adding the whipped cream and serving.
Make ahead tip: This Black Forest Tart is ideal for making a day in advance. The filling sets beautifully overnight and the flavors deepen.
Ways to Serve Black Forest Tart
With a dusting of cocoa powder: A light sift of unsweetened cocoa over the whipped cream gives it that classic Black Forest look before guests arrive.
Alongside a warm drink: A cup of dark coffee or a simple hot chocolate makes the rich chocolate mousse taste even better. If you love cozy baked treats with your coffee, my Coffee Cake Cookies are a natural companion.
With vanilla ice cream: A small scoop of vanilla on the side turns this into an extra-indulgent plate for birthday dinners or holiday celebrations.
On a dessert board: Slice the tart into thin pieces and arrange them alongside Cookie Dough Cheesecake for a chocolate-lover's dream spread.
Expert Tips
Don't skip the moisture barrier. That thin layer of melted chocolate brushed over the crust before adding the compote is what keeps the Oreo base crisp. Skip it and you'll end up with a soggy bottom by the time you slice.
Let the ganache cool fully before folding. If it's still warm when you fold in the whipped cream, it'll deflate and the mousse won't hold its airy texture. It should feel slightly cool to the touch and thick but still pourable.
Stiff peaks, not dry peaks. Watch the cream carefully when whipping. You want stiff peaks that hold their shape, but if you go too far, the cream will look grainy and won't fold smoothly into the ganache.
Chill between layers if needed. If at any point the mousse or the compote seems too loose to layer cleanly, just pop the tart back into the fridge for 10-15 minutes before continuing.
FAQ
How do you make a Black Forest chocolate mousse tart?
Start with a homemade cherry compote, an Oreo crust, and a chocolate ganache-based mousse. The mousse is made by folding whipped cream into cooled ganache until it's light and silky. Once layered in the pan, it chills for about an hour until fully set. No baking required. A family tip: get the compote done first so it has time to cool completely before you need it.
Can I use frozen cherries for a Black Forest tart?
Absolutely. Frozen cherries work just as well as fresh for the compote. You don't even have to thaw them ahead of time; just add them directly to the saucepan and let them cook down with the sugar and cornstarch. The result is just as rich and jammy.
What chocolate is best for chocolate mousse?
Semi-sweet or dark chocolate (around 60-70% cacao) gives the best balance of richness and sweetness. Milk chocolate can work but will make the mousse sweeter and a little less complex. Avoid white chocolate here as the mousse structure depends on a proper ganache base.
Why isn't my chocolate mousse setting?
A few common reasons: the ganache was still too warm when you folded in the whipped cream, causing it to deflate; the cream wasn't whipped to stiff peaks; or the tart didn't chill long enough. If your mousse looks loose after assembly, give it another 30 minutes in the fridge or a brief 10-minute stint in the freezer. It usually firms right up.

Ingredients
Method
- Finely chop the cherries, then stir them with the sugar and the cornstarch slurry in a saucepan. Cook over medium heat, stirring often, until thick and glossy like pie filling. Transfer to a bowl and cool completely.
- Blend the chocolate sandwich cookies into fine crumbs, then mix with the melted butter until evenly coated.
- Press the crumb mixture firmly across the bottom and slightly up the sides of a tart pan using the bottom of a measuring cup for an even layer.
- Freeze the crust for 10 minutes or refrigerate for 20 minutes until firm enough to hold its shape.
- Place the chocolate together with ¾ cup of the heavy cream in a heatproof bowl set over gently simmering water. Stir until completely smooth, then remove from the heat and let cool until no longer warm but still fluid.
- Spread a thin layer of the cooled chocolate mixture over the chilled crust, reaching the edges to create a moisture barrier. Refrigerate while preparing the mousse, and chill the remaining ganache until it reaches room temperature.
- Whip the remaining heavy cream with the powdered sugar until stiff peaks form while the cream still looks smooth and glossy. Reserve about one-third of the whipped cream for decorating and refrigerate it.
- Fold one-third of the remaining whipped cream into the cooled ganache to lighten it, then gently fold in the rest until a smooth chocolate mousse forms without deflating the cream.
- Spread a thin, even layer of the cooled cherry compote over the crust, reserving a little for garnish if desired.
- Spoon the chocolate mousse over the cherry layer and smooth the top evenly with an offset spatula.
- Refrigerate the tart for about 1 hour and 20 minutes, or until the mousse is fully set and slices cleanly.
- Pipe or spoon the reserved whipped cream onto the chilled tart and garnish each serving with the remaining cherry compote before serving.
