Chocolate Raspberry Tart Recipe

This chocolate raspberry tart is a cocoa shortcrust shell filled with a soft white chocolate cream full of crushed fresh raspberries, then topped with a glossy dark chocolate ganache. It makes one 9 inch tart, 10 to 12 slices, with about 50 minutes of hands-on work and a long, quiet stretch of chilling.

The trick is a thin coat of melted dark chocolate brushed over the baked shell before anything creamy goes in. It sets in 10 minutes and keeps the crust crisp for days.

Three Layers, Three Jobs

• Cocoa shell: structure and snap. Flour, cocoa, powdered sugar, cold butter and one egg yolk.
• Dark chocolate seal: 60 g brushed paper thin over the base. It keeps moisture out of the crust.
• White chocolate raspberry cream: 115 g white chocolate, ¼ cup cream, vanilla and ¾ cup crushed raspberries. Soft and spoonable, never firm.
• Ganache top: 170 g dark or semi sweet chocolate, ½ cup cream and 1 tablespoon butter. Sets firm and shiny.

Each layer sets on its own before the next goes on. That is what keeps the cut side looking like stripes instead of a brown swirl.

Plan the Chill Before You Start

The recipe card lists 30 minutes of prep, 20 minutes in the oven and 2 hours of extra time. Read the steps, though, and the waits add up: 30 minutes to chill the dough, 10 in the freezer, a full cool for the baked shell, 10 minutes for the seal, at least 1 hour for the white layer and at least 2 hours for the ganache.

So give it half a day. Easier still, bake and seal the shell the day before, keep it covered at room temperature, and do the two fillings the next morning.

The Cocoa Shell: Cold Butter and a Short Chill

Powdered sugar blends into the flour and cocoa without grit and gives a fine, sandy crumb. Keep the butter cold and rub it in only until the mix looks like coarse crumbs. Cold butter keeps the dough short and snappy, and it stops the shell slumping down the fluted sides as it bakes. The egg yolk binds it; add the second spoon of water only if the dough will not hold together when squeezed.

Roll it out, press it into a 9 inch fluted tart pan, prick the base and freeze it for the full 10 minutes. Then bake at 350°F (175°C) with parchment and pie weights for 15 minutes, and 5 more without them.

A cocoa crust hides its colour, so judge it by feel. The base should look dry and matte, the edges should feel firm, and the kitchen should smell of toasted cocoa. Cool it completely in the pan.

Why the Dark Chocolate Seal Matters

Melt the 60 g of dark chocolate gently and brush a very thin layer over the bottom of the cooled shell. Chill 10 minutes. It is not a layer you taste much. It is a waterproof lining, and without it the white chocolate cream softens the crust by the next day.

White Chocolate Cream With Crushed Raspberries

Heat the cream until it just steams, pour it over the chopped white chocolate, wait a minute and stir until smooth. Add the vanilla. That is roughly 2 parts white chocolate to 1 part cream by weight. White chocolate has no cocoa solids, so at this ratio it stays soft and creamy instead of setting hard like a dark ganache.

Let it cool until it feels just warm on your lip. Hot cream melts the seal and leaks into the crust.

Crush the raspberries with a fork into small pieces, not a purée, and scatter them over the sealed base. Pour the white chocolate over them and tilt the pan to spread it. Do not stir, or the cream turns pink and the streaks disappear. Chill at least 1 hour. It is ready when it holds a fingertip dent without jiggling.

Fresh or Frozen Raspberries Here?

Fresh berries that give a little when pressed crush best. Frozen ones work if you thaw them fully and drain the juice, which would otherwise thin the cream. You lose some texture, and the ganache hides any colour bleed. If you have raspberries left over, they go well in fudgy chocolate cookies with raspberry or raspberry snowball truffles.

Dark or Semi Sweet Chocolate for the Ganache?

The card allows either, and they give two different tarts.

• Dark chocolate (around 60 to 70 percent): a firmer, slightly bitter top that cuts the sweetness of the white layer. This is the dark chocolate raspberry tart most people picture.
• Semi sweet chocolate: sweeter and a touch softer once set. A good choice if you are serving children or you like milder chocolate.

Either way the ratio is 170 g chocolate to 120 ml cream, firmer than a pouring chocolate ganache for drips, so it slices cleanly. Bring the cream just to a simmer, pour it over the chocolate, wait a minute or two, stir until glossy, then stir in the butter for shine.

Let the ganache cool 5 to 10 minutes before pouring it over the white layer. Smooth it with an offset spatula and chill at least 2 hours, until it is firm and a knife comes out without smears.

When the Ganache Sinks or the Crust Goes Soft

• Ganache sank into the white layer: the white layer was not set, or the ganache was poured hot. Wait for the fingertip dent test and let the ganache cool first.
• Ganache looks oily or grainy: it got too hot. Stir in a tablespoon of warm cream from the centre out until it turns glossy again.
• Shell shrank down the sides: the dough was warm going into the oven. Do not skip the 10 minutes in the freezer.
• Crust soft on day two: the seal was patchy, or the white chocolate cream went in hot. Brush the seal all the way to the edges.
• Messy slices: dip a sharp knife in hot water, wipe it dry, cut, and wipe it again between every slice.

Making It Ahead and Storing Leftovers

Keep the finished tart covered in the fridge for up to 4 days. The shell stays crisp thanks to the seal. Add the fresh raspberry topping close to serving so the berries do not weep onto the ganache.

To freeze, wrap the tart tightly before the fresh raspberries go on and freeze it flat. Thaw overnight in the fridge, then decorate. Do not try to slice it frozen, the ganache cracks. For single servings that store even more neatly, chocolate raspberry cheesecake domes are a good make-ahead option.

Quick Answers on Shells, Pans and Swaps

Can I use a store-bought tart shell?

Yes. Use a 9 inch baked shell and still brush it with the melted dark chocolate seal before filling.

Can I make it in a pie plate?

You can, but a fluted tart pan with a removable bottom lets you lift the tart out and shows the layers on the sides. In a pie plate, serve it from the dish.

What other chocolate tarts can I try?

For a single, rich chocolate filling, try this Gordon Ramsay chocolate tart. For nuts instead of fruit, the chocolate pistachio tart uses a similar crust.

Can I make the white layer firmer?

Use a little less cream and it sets firmer, closer to a white chocolate ganache filling. Keep the raspberries well drained either way.
