Delia Smith Black Forest Gateau Recipe

Jump to Recipe Print Recipe

This Delia Smith style Black Forest Gateau is a classic chocolate sponge layer cake filled with whipped cream, cherries, and a perfectly boozy kirsch syrup. It’s light and airy in texture, but rich in flavour, with that unmistakable pairing of cocoa, vanilla cream, and sweet-tart cherries. I’d call it a confident intermediate bake, mostly because assembly matters more than fancy techniques. Set aside about 2 hours 30 minutes total, including cooling and chilling time.

How to Make Delia Smith Black Forest Gateau Recipe

Prepare the oven and tins

Prepare the oven: Preheat to 180°C (160°C fan). Set a shelf in the middle so the cakes rise evenly.
Prepare the tins: Grease and line three 20cm (8-inch) sandwich tins with baking parchment on the bases. This makes turning out clean and stress-free.

Mix the sponge

Whisk eggs and sugar: Crack the eggs into a large mixing bowl, add the caster sugar and vanilla, then whisk with an electric mixer for 5 to 8 minutes until very pale, thick, and leaving a ribbon trail when you lift the whisk.
Fold in the dry ingredients: Sift together the flour, cocoa, baking powder, and salt. Sprinkle over the whisked mixture and fold gently using a large metal spoon or spatula. Take your time and keep as much air as you can.
Add the melted butter: Pour the cooled melted butter down the side of the bowl and fold again, just until no streaks remain. Overmixing here can knock the lightness out of the sponge.

Bake

Divide the batter: Spoon the mixture evenly into the prepared tins and level the tops gently.
Bake: Bake for 20 to 25 minutes, until the sponges look set, spring back when lightly pressed, and a skewer comes out clean.

Cool completely

Cool in the tins: Leave the cakes in their tins for 10 minutes so they firm up a little.
Turn out and cool: Turn out onto a wire rack, peel off the parchment, and cool completely before assembling. Warm cake will melt the cream and cause sliding.

Make the syrup, whip the cream, and assemble

Make the kirsch syrup: In a small saucepan, warm the reserved cherry syrup with the caster sugar just until the sugar dissolves. Cool, then stir in the kirsch.
Whip the cream: Whip the cold double cream with icing sugar and vanilla until soft peaks form. You want it billowy and spreadable, not stiff or grainy.
Start layering: Place one sponge on a serving plate. Brush generously with the kirsch syrup. Spread over a layer of whipped cream and scatter over a third of the drained cherries.
Repeat: Add the second sponge, brush with syrup, then add cream and cherries. Top with the final sponge and brush the top with a little more syrup.
Finish and decorate: Cover the top and sides with the remaining cream. Finish with chocolate curls or shavings and decorate with whole cherries.
Chill before slicing: Refrigerate for at least 1 hour so the cream sets slightly and the flavours settle. This makes clean slices much easier.

Tips for the Best Black Forest Gateau

Why did my chocolate sponge sink or turn dense?

The most common cause is under-whisking the eggs and sugar, or over-folding once the flour goes in. Whisk until the mixture is thick enough to leave a clear ribbon, then fold gently and stop as soon as you no longer see dry pockets.

How do I stop the whipped cream from splitting or going grainy?

Use very cold double cream, and whisk to soft peaks, not stiff. If you go too far, it starts to look slightly lumpy and will only get worse. It helps to chill your bowl and whisk for 10 minutes first if your kitchen is warm.

How much kirsch should I use for the right flavour?

Start with 3 tablespoons, taste the cooled syrup, then add another tablespoon if you want a more traditional, grown-up bite. The syrup should taste cherry-forward with a gentle warmth, not harsh.

How do I get chocolate curls and shavings that look bakery-neat?

Use a bar of dark chocolate and a vegetable peeler. If the chocolate is too cold it will snap, so let it sit at room temperature for 10 minutes, then peel along the edge to make curls. For fine shavings, grate it on the large holes of a box grater.

Serving Suggestions

Serve with extra drained cherries on the side and a spoonful of syrup for drizzling.
Add a scoop of vanilla ice cream if you want it extra indulgent.
Pair with strong coffee or espresso to balance the sweetness.
For a festive finish, dust lightly with cocoa just before serving.

Storage

Room Temperature

This gateau is best kept chilled because of the cream. If your room is cool and you’re serving within a few hours, it can sit out briefly, but do not leave it at room temperature for more than 2 hours.

Refrigerator

Store covered in the fridge for up to 3 days. A cake dome or large airtight container helps prevent it from picking up fridge odours and keeps the cream from drying out.

Freezing

For best results, freeze the unfilled chocolate sponge layers. Wrap each layer tightly in cling film, then foil, and freeze for up to 2 months. Thaw overnight at room temperature (still wrapped), then assemble fresh. Freezing a fully assembled cream cake can change the texture of the cream and cause weeping when thawed.

FAQs

Can I make Black Forest Gateau without kirsch?

Yes. Replace the kirsch with extra reserved cherry syrup (or cherry juice) and add 1 teaspoon vanilla extract or a small squeeze of lemon to keep the flavour bright. You will still get a classic chocolate-and-cherry result, just without the traditional boozy note.

What cherries are best for Black Forest Gateau?

Morello cherries in syrup are the most reliable because they are tart enough to balance the cream and chocolate, and they stay soft and juicy. If using fresh cherries, pit them and macerate with a little sugar for 20 to 30 minutes before assembling.

Can I bake the sponges in two tins instead of three?

Yes. Use two 20cm tins and bake a little longer, usually 25 to 30 minutes. Once fully cool, you can slice each cake in half horizontally to create more layers, or keep it as a simple two-layer gateau.

How far ahead can I assemble Black Forest Gateau?

You can assemble it up to 24 hours ahead and keep it refrigerated. In fact, the flavour improves as the sponge absorbs the cherry syrup. Add the final chocolate shavings and cherries shortly before serving for the freshest look.

Why is my gateau sliding or leaning?

This usually happens when the sponges are still slightly warm, the cream is whipped too softly, or the syrup is over-applied in one spot. Make sure the cakes are completely cool, whip the cream to soft peaks (not runny), and brush syrup evenly over each layer.
