What Is a Black Forest Traybake?

A black forest traybake takes all the beloved components of the classic Black Forest Gateau, or Schwarzwalder Kirschtorte, and bakes them in a flat rectangular tin rather than stacking round layers. The original cake hails from the Black Forest region of southwestern Germany, where sour Morello cherries grow in abundance. Traditionally, bakers layer rich chocolate sponge with whipped cream and a cherry filling, then crown the whole creation with chocolate shavings.

The traybake version keeps every one of those flavours intact but removes the fiddly layering process. You spread a single sheet of moist chocolate sponge across a lined tray, top it with fruit and cream, and slice it into neat squares. This makes the traybake far easier to transport, serve, and share at gatherings. According to the Royal Society of Chemistry, cocoa powder owes its deep colour and bittersweet character to flavanols and theobromine, two compounds that also contribute health-promoting antioxidant properties.

Because you bake just one even layer of sponge, the cooking time drops significantly, and you avoid the common headache of wobbly, lopsided layers. The result looks just as impressive as its round cousin when you scatter dark chocolate curls across the cream and dot the surface with glossy cherries. If you enjoy recipes like our chocolate hazelnut Victoria sponge cake or our easy banoffee pie, this black forest traybake sits perfectly alongside them in your baking repertoire.

Ingredients for an Authentic Black Forest Traybake

Every great bake starts with quality ingredients measured carefully. Below you will find everything you need for the sponge, the cherry compote, and the cream topping. I recommend reading through the full list before you begin so that nothing catches you off guard.

Ingredient	Quantity	Notes
Plain flour	200 g	Sifted
Cocoa powder	40 g	Sifted, use good quality
Baking powder	1 1/2 tsp	Check expiry date for best rise
Sea salt	Pinch	Fine sea salt preferred
Unsalted butter	150 g	Softened at room temperature
Caster sugar	200 g	Golden caster sugar also works well
Large eggs	3	At room temperature
Milk	50 ml	Whole milk for best richness
Morello cherries (jarred)	300 g	Drained, reserve 100 ml juice
Cornflour	1 tsp	Mixed with 1 tbsp cold water
Double cream	300 ml	Chilled straight from the fridge
Icing sugar	2 tbsp	Sifted
Dark chocolate	50 g	70% cocoa, for shaving

Choosing the Right Cocoa Powder

The cocoa powder you select shapes the entire flavour profile of your sponge. Dutch-process cocoa delivers a darker colour and a milder, more rounded chocolate taste because manufacturers treat it with an alkalising agent that neutralises the natural acidity. Natural cocoa powder, on the other hand, keeps its slightly sharp, fruity edge and works particularly well when paired with tart Morello cherries. Either option produces a delicious result, so choose based on your personal preference. Look for a brand with at least 20% cocoa butter content for the richest flavour.

The Best Cherries to Use

Morello cherries bring the signature sour tang that sets a black forest traybake apart from any ordinary chocolate cake. You can find jarred Morello cherries in syrup at most UK supermarkets, and they save you the effort of pitting fresh fruit. If Morellos prove hard to source, dark sweet cherries (sometimes labelled Bing cherries) make a perfectly acceptable swap, though the finished traybake will taste noticeably sweeter. Frozen sour cherries, defrosted and drained, also work beautifully in the compote step.

Smart Substitutions

For a dairy-free sponge, replace the butter with a plant-based block margarine and use oat milk instead of whole milk. Swap the double cream topping for a whippable coconut cream. If you need a gluten-free version, use a one-to-one gluten-free plain flour blend and add half a teaspoon of xanthan gum to keep the crumb structure intact. Our gluten-free brownies recipe uses a similar approach and delivers outstanding results.

Equipment You Need

You do not need any specialist equipment to make this traybake. Here is a simple checklist of tools you will want within reach before you start mixing:

• A 20 x 30 cm baking tray (a standard Swiss roll tin works perfectly)
• Baking parchment for lining
• Two large mixing bowls
• An electric hand whisk or stand mixer
• A rubber spatula for folding
• A fine-mesh sieve for the cocoa and flour
• A small saucepan for the cherry compote
• A wire cooling rack
• A vegetable peeler or sharp knife for chocolate shavings

A stand mixer speeds up the creaming stage noticeably, but a hand-held electric whisk handles the job with minimal fuss. Avoid using a wooden spoon to whip cream, as it takes far too long and often results in an under-whipped topping that slides off the sponge.

How to Make Black Forest Traybake (Step-by-Step)

Follow these detailed steps and you will produce a picture-perfect black forest traybake on your very first attempt. I break the process into clear stages so that even a complete beginner can bake with confidence.

Preparing the Tin and Oven

Step 1: Preheat and Line

Set your oven to 180 degrees Celsius (fan). Cut a sheet of baking parchment large enough to line the base and sides of your 20 x 30 cm tray. Press the paper firmly into the corners and let the edges overhang slightly. This overhang gives you handles for lifting the cooled sponge out of the tray later.

Making the Chocolate Sponge Batter

Step 2: Sift the Dry Ingredients

Place a fine-mesh sieve over a mixing bowl. Add the plain flour, cocoa powder, baking powder, and sea salt, then sift everything together. Give the bowl a gentle shake to distribute the raising agent evenly. Sifting at this stage removes lumps and introduces air, which helps the sponge rise evenly. As BBC Good Food notes, thorough sifting and creaming form the foundation of a light, tender cake crumb.

Step 3: Cream the Butter and Sugar

In a separate large bowl, beat the softened unsalted butter and caster sugar together using an electric whisk on medium-high speed. Continue for about four minutes until the mixture turns pale, fluffy, and noticeably increased in volume. This creaming step traps tiny air bubbles in the fat, and those bubbles expand in the oven to give you a light sponge. If your butter feels cool and firm, cut it into small cubes and let it sit at room temperature for 30 minutes before you start.

Step 4: Add the Eggs and Milk

Add the eggs one at a time, beating well for about 30 seconds between each addition. Adding them gradually prevents the batter from curdling. Once all three eggs are incorporated, pour in the milk and stir briefly to combine. If the mixture looks slightly split at this point, do not worry; folding in the flour in the next step brings everything back together.

Step 5: Fold in the Dry Ingredients

Tip the sifted dry ingredients into the creamed mixture. Use a rubber spatula or large metal spoon to fold everything together with slow, gentle movements. Cut down through the centre of the bowl, sweep along the bottom, and fold the batter over itself. Repeat until you can see no streaks of flour, then stop immediately. Over-mixing at this stage knocks out the air you worked so hard to incorporate and produces a dense, heavy sponge.

Baking the Sponge

Step 6: Bake Until Just Set

Pour the batter into your lined tray and use the spatula to spread it into an even layer, paying extra attention to the corners. Place the tray on the middle shelf of your preheated oven and bake for 20 to 25 minutes. The sponge is ready when the surface springs back gently to the touch and a skewer inserted into the centre comes out clean. Transfer the tray to a wire rack and leave the sponge to cool completely inside the tray before you begin assembling. A warm sponge melts the cream and creates a soggy result, so patience at this stage pays off handsomely.

Preparing the Cherry Compote

Step 7: Simmer the Cherry Syrup

While the sponge cools, pour the reserved 100 ml of cherry juice into a small saucepan. Add a tablespoon of caster sugar and bring the liquid to a gentle simmer over a medium heat. In a small cup, mix the cornflour with one tablespoon of cold water until smooth. Pour this slurry into the simmering juice, stirring constantly. Cook for one to two minutes until the syrup thickens enough to coat the back of a spoon. Remove the pan from the heat, toss the drained Morello cherries through the glossy syrup, and set the compote aside to cool completely.

Assembling the Traybake

Step 8: Whip the Cream

Pour the chilled double cream into a clean, cold mixing bowl. Add the sifted icing sugar. Whip with an electric whisk on medium speed until the cream forms soft peaks that hold their shape but still look glossy and smooth. Stop as soon as you reach this stage; over-whipped cream turns grainy and eventually separates into butter. For best results, chill the bowl and whisk in the freezer for ten minutes before you begin whipping. This technique mirrors the approach in our chocolate marquise recipe, where perfectly whipped cream defines the final texture.

Step 9: Layer the Cream and Cherries

Spread half of the whipped cream in an even layer over the cooled sponge. Scatter half of the cherry compote (including some of the syrup) across the cream. Dollop the remaining cream in generous spoonfuls over the cherries and use the back of a spoon to create gentle swirls rather than a flat surface. Distribute the remaining cherries on top, pressing them lightly into the cream so they stay anchored when you slice.

Step 10: Finish with Chocolate Shavings

Take the 50 g bar of dark chocolate and run a vegetable peeler along the thin edge to create curls and shavings. Scatter these generously over the entire surface of the traybake. For larger, more dramatic curls, warm the chocolate bar very slightly in your hands for a few seconds before peeling. Cover the traybake loosely and chill in the refrigerator for at least one hour. This resting time firms the cream, melds the flavours, and makes slicing much cleaner. You can chill for up to 24 hours if you prefer to prepare it a day ahead.

Troubleshooting Your Black Forest Traybake

Even experienced bakers encounter the occasional hiccup. Here are the most common problems and exactly how to fix them.

Why Did My Sponge Sink in the Middle?

A sunken centre almost always results from opening the oven door too early or from under-baking. Keep the oven door shut for the first 15 minutes of baking. After that point, open the door gently and briefly if you need to check progress. If your sponge still sinks, check that your baking powder has not expired; stale raising agents lose their potency and fail to hold the crumb structure.

Why Does My Cream Slide Off the Sponge?

Cream sliding off usually means you assembled the traybake while the sponge was still warm. Always cool the sponge completely, ideally to room temperature, before you add any cream. Another cause is under-whipped cream; if it does not hold soft peaks, it cannot support its own weight on the sponge. Whip it a little longer, checking every 15 seconds.

My Chocolate Sponge Tastes Bitter – What Went Wrong?

Bitterness in a chocolate sponge typically comes from using too much cocoa powder or from choosing a very high-cocoa-percentage variety without adjusting the sugar. Stick to the 40 g measurement in this recipe and use a cocoa powder rated between 20% and 22% fat for the most balanced flavour. If you prefer a sweeter sponge, add an extra tablespoon of caster sugar to the batter. Our old school chocolate sponge cake recipe offers another reliable chocolate base if you want to compare techniques.

The Cherry Compote Is Too Runny

A thin compote means the cornflour slurry did not cook long enough to activate its thickening power. Next time, bring the syrup to a proper simmer and stir continuously for a full two minutes after adding the cornflour mixture. You can also rescue a runny compote by returning it to the heat, adding another half teaspoon of cornflour mixed with a tablespoon of cold water, and cooking until thickened.

How Do I Get Clean Slices?

Chilling the traybake for at least one hour firms the cream and makes slicing far easier. Use a large, sharp knife dipped in hot water and wiped dry between each cut. This method melts through the cream cleanly rather than dragging it across the sponge.

Recipe Variations

One of the best things about this black forest traybake is how well it adapts to different tastes and dietary needs.

Vegan Black Forest Traybake

Replace the butter with 150 g of vegan block margarine and use plant-based milk in the sponge. Substitute the eggs with 3 tablespoons of ground flaxseed mixed with 9 tablespoons of warm water and left to gel for 10 minutes. For the topping, whip chilled full-fat coconut cream with icing sugar until thick. The flavour remains rich and deeply chocolatey.

Gluten-Free Version

Swap the plain flour for a one-to-one gluten-free flour blend and add half a teaspoon of xanthan gum to strengthen the crumb. Everything else in the recipe stays exactly the same. Test the sponge with a skewer a few minutes earlier, as gluten-free batters sometimes bake faster.

White Chocolate and Cherry Variation

For a lighter take, reduce the cocoa powder to 20 g and add 20 g of melted white chocolate to the batter alongside the milk. Top the finished traybake with white chocolate shavings instead of dark. This version pairs beautifully with slightly sweeter Bing cherries.

Individual Black Forest Cups

Bake the sponge as directed, then use a round cutter to stamp out circles that fit into glass tumblers or dessert jars. Layer sponge, cherry compote, and whipped cream inside each glass. These individual portions look stunning at dinner parties and can sit in the fridge until you are ready to serve. This presentation style follows the same logic as our cookie pie recipe, where individual portions create an impressive visual impact.

Serving and Storage

How to Serve Your Black Forest Traybake

Remove the traybake from the fridge about 15 minutes before serving so the cream softens just enough. Slice into 12 generous squares using a hot, clean knife. Serve each piece on a small plate with an extra drizzle of any remaining cherry syrup. For a special occasion, add a scoop of vanilla ice cream alongside or a pour of warm British chocolate custard for an indulgent finishing touch.

Storage Guidelines

Cover the traybake tightly with cling film or transfer slices to an airtight container and refrigerate. The traybake keeps well for up to three days in the fridge, and the flavours actually develop and deepen overnight as the cherry syrup soaks gradually into the sponge. I do not recommend freezing the assembled traybake because the whipped cream changes texture when thawed. However, you can freeze the un-topped sponge, wrapped tightly in cling film and foil, for up to two months. Defrost it fully at room temperature before assembling.

Reheating Tips

This traybake tastes best cold, straight from the fridge. If you prefer a slightly warmer sponge, you can gently warm individual portions (without the cream topping) in a microwave on low power for 15 seconds. Add fresh cream and cherries after warming.

Frequently Asked Questions (FAQ)

Can I make black forest traybake the day before?

Yes, you absolutely can. In fact, preparing this traybake a day ahead gives the cherry syrup time to soak into the sponge, which intensifies the flavour. Assemble the full traybake, cover it tightly with cling film, and store it in the refrigerator overnight. Add the chocolate shavings just before serving for the freshest look.

What is the difference between Black Forest cake and Black Forest traybake?

The traditional Black Forest Gateau uses round, stacked layers of sponge with cream and cherries between each layer. A black forest traybake bakes all the sponge in a single flat tray and tops it with cream and cherries in one layer. The traybake version is significantly easier to assemble, transport, and slice, making it ideal for parties and gatherings.

Can I use frozen cherries instead of jarred?

Frozen sour cherries work perfectly in this recipe. Defrost them fully in a sieve set over a bowl, then use the collected juice in place of the reserved jar liquid. You may need to simmer the juice a little longer to reduce it to the right consistency for the compote.

How do I stop the chocolate shavings from melting?

Chocolate shavings soften quickly at room temperature. Keep the finished traybake in the fridge and add the shavings as close to serving time as possible. On warm days, you can chill the dark chocolate in the fridge for 20 minutes before shaving. This keeps the curls firm and gives them a satisfying snap.

Is black forest traybake suitable for children?

This recipe contains no restricted ingredients and suits all ages perfectly. The combination of chocolate sponge, cream, and fruit makes it a favourite with children at birthday parties and school events.

Why do the cherries sink into my sponge?

Cherries should sit on top of the cream, not inside the sponge batter. If you add them to the raw batter, their weight pulls them to the bottom during baking. Always scatter cherries over the whipped cream after the sponge has cooled completely.
