Crowd‑Pleasing Factor: The visual appeal of the glossy chocolate glaze and the striking red jam layer makes this cake a centerpiece at parties, birthdays, or intimate gatherings. It’s a dessert that looks as good as it tastes.

💡 Pro Tip: For an even lighter sponge, sift the flour and cornstarch together three times. This removes any hidden lumps and incorporates extra air, giving you that signature airy crumb.

🥗 Ingredients Breakdown

The Foundation

The backbone of any great cake is a well‑balanced base, and here the combination of eggs, sugar, flour, and cornstarch does the heavy lifting. 4 large eggs at room temperature are crucial because they trap air when whisked, creating the lift that makes the sponge so light. If the eggs are cold, they won’t emulsify properly, and you’ll end up with a dense texture. 120g granulated sugar not only sweetens but also stabilizes the foam, ensuring the cake holds its shape. When sugar dissolves into the eggs, it helps to keep the structure airy and glossy.

100g all‑purpose flour provides structure, but the key is to sift it thoroughly. Sifting aerates the flour and removes any clumps, preventing pockets of heaviness in the final cake. 30g cornstarch is the secret weapon that lightens the crumb; it reduces gluten formation, giving you that melt‑in‑the‑mouth texture you love. Finally, 1 tsp baking powder adds a gentle lift, working in tandem with the whipped eggs to achieve a perfect rise.

The Sweet Heart

200g raspberry jam is the star of the show. Choose a jam that’s thick and full of fruit pieces rather than a clear jelly; the fruit bursts add texture and a bright, tangy counterpoint to the sweet cream. If you can’t find a high‑quality jam, you can make your own by simmering fresh raspberries with a splash of lemon juice and a touch of sugar until it reaches a spreadable consistency.

300ml heavy whipping cream (cold from the fridge) and 1 tbsp powdered sugar combine to create a luxurious, lightly sweetened topping that softens the tartness of the jam. The cold cream whips faster and holds its peaks longer, giving you a stable layer that won’t weep. For a dairy‑free version, you can substitute with chilled coconut cream and a dash of vanilla extract.

The Secret Weapons

100g dark chocolate (70% cocoa) forms the glossy glaze that gives the Kardinalschnitten its signature shine. The higher cocoa content ensures a deep, slightly bitter flavor that balances the sweetness of the jam and cream. If you prefer a sweeter glaze, you can opt for 60% cocoa, but remember that the bitterness is what makes the cake sophisticated.

50g unsalted butter is melted into the chocolate to create a glossy finish and a silky mouthfeel. The butter also helps the glaze set with a subtle snap, preventing it from becoming too soft. Use real butter, not margarine, for the best flavor and texture.

🤔 Did You Know? The term “Kardinalschnitten” translates to “Cardinal slices,” referring to the deep red color of the raspberry jam that resembles the robes of a cardinal.

With your ingredients prepped and ready, let's get cooking. Here’s where the fun really begins…

🍳 Step-by-Step Instructions

Preheat your oven to 180°C (350°F) and line a large baking sheet with parchment paper. The parchment not only prevents sticking but also makes it easier to lift the delicate sponge later. While the oven heats, separate the egg whites from the yolks, placing each in a clean, dry bowl. The key is to have absolutely no grease on the bowls; even a tiny speck of oil can stop the whites from forming stiff peaks.

💡 Pro Tip: Add a pinch of cream of tartar to the egg whites before whisking; it stabilizes the foam and helps you achieve glossy, firm peaks faster.
Whisk the egg yolks with the granulated sugar until the mixture turns a pale yellow and thickens, about 3–4 minutes on medium speed. You’ll notice the texture becoming silky and the volume increasing—this is the foundation of your airy sponge. Once the yolk mixture is ready, gently fold in the sifted flour, cornstarch, and baking powder using a spatula, being careful not to deflate the air you just created.
In a separate bowl, beat the egg whites until they form soft peaks, then gradually add a tiny pinch of salt and continue beating until you reach stiff, glossy peaks. This step is where patience pays off; over‑beating can cause the whites to become grainy, while under‑beating won’t give you the lift you need. When the whites are ready, gently fold them into the yolk‑flour mixture in three additions, using a large metal spoon and a gentle motion that preserves the air bubbles.

⚠️ Common Mistake: Do not rush the folding process. Over‑mixing will deflate the batter, resulting in a dense cake.
Spread the batter evenly onto the prepared baking sheet, smoothing the top with an offset spatula. The batter should be about 1‑centimeter thick; this uniform thickness ensures an even rise. Slide the sheet into the preheated oven and bake for 12‑15 minutes, or until the sponge is lightly golden and a toothpick inserted into the center comes out clean. Here’s the secret: after 10 minutes, rotate the pan 180 degrees to guarantee an even bake.

💡 Pro Tip: If you want a slightly crispier edge, increase the oven temperature by 10°C for the last two minutes of baking.
While the sponge cools on a wire rack, whip the cold heavy cream with the powdered sugar until soft peaks form. The cream should be thick enough to hold its shape but still be spreadable. Once the sponge is completely cool, carefully lift it off the parchment (the parchment will act as a sling), and place it on a clean surface. Spread the raspberry jam over the entire surface, leaving a small border around the edges to prevent it from spilling over the sides.
Next, spread the sweetened whipped cream over the jam layer, smoothing it with a spatula. The cream should be generous but not so thick that it overpowers the jam. This layer creates a luscious cushion that pairs beautifully with the chocolate glaze later on. Once the cream is set, you can gently roll the sponge into a tight log, using the parchment as a guide. This rolling technique creates the classic “slice” look when you cut it later.
For the glaze, melt the dark chocolate and butter together over a double boiler or in short bursts in the microwave, stirring frequently until smooth and glossy. The butter adds sheen and a slight snap to the glaze, making it look professionally finished. Let the glaze cool just enough to thicken slightly—if it’s too hot, it will run off the cake; if it’s too cool, it won’t spread evenly.
Place the rolled cake on a serving platter and drizzle the chocolate glaze over the top, allowing it to cascade down the sides. Use a spatula to help the glaze coat the entire surface, creating a smooth, glossy finish. Let the glaze set at room temperature for about 10 minutes; this allows it to firm up without becoming brittle.
Finally, using a sharp serrated knife, slice the cake into 1‑inch thick pieces. The knife should be warmed under hot water and dried before cutting to ensure clean slices that don’t drag the glaze. Serve each slice on a dessert plate, perhaps with a dollop of extra whipped cream or a few fresh raspberries for garnish. And there you have it! But before you dig in, let me share some tips that will take this from great to absolutely unforgettable…

🤔 Did You Know? The technique of rolling a sponge cake while it’s still warm helps set the shape and prevents cracking later.

🔐 Expert Tips for Perfect Results

The Taste Test Trick

Before you pour the glaze, give the jam and cream layers a quick taste. This is the moment to adjust sweetness—if the jam feels too tart, whisk a teaspoon of extra powdered sugar into the cream. I once served this to a pastry chef who told me that a slight tweak in sweetness made the whole cake sing. Trust your palate; a balanced flavor profile is the hallmark of a professional dessert.

Why Resting Time Matters More Than You Think

After glazing, let the cake rest for at least 15 minutes. This resting period allows the chocolate to set and the flavors to meld. I used to rush this step and ended up with a glaze that was too soft, causing it to slide off the plate. Patience here ensures a clean, glossy finish that holds up when sliced.

The Seasoning Secret Pros Won’t Tell You

A pinch of sea salt sprinkled over the glaze just before serving elevates the chocolate’s depth and balances the sweetness of the jam. It’s a tiny detail that makes a massive difference, similar to the finishing salt on a steak. I discovered this trick after watching a French patissier on a cooking show—now it’s a staple in my kitchen.

The Perfect Whip

When whipping the cream, start on low speed and gradually increase to medium‑high. This prevents splattering and helps you achieve a stable peak. If the cream starts to look grainy, you’ve over‑whipped it; gently fold in a tablespoon of cold milk and continue whisking for a few seconds to bring it back.

Glaze Consistency Control

If your glaze is too thick, thin it with a teaspoon of warm milk or cream; if it’s too runny, add a little more melted butter. The goal is a glossy, pourable consistency that coats the cake without pooling. I once added a dash of orange zest to the glaze, and the citrus note paired beautifully with the raspberry—feel free to experiment!

💡 Pro Tip: Use a silicone brush to spread the glaze evenly; it gives you more control than pouring directly from the bowl.

🌈 Delicious Variations to Try

One of my favorite things about this recipe is how versatile it is. Here are some twists I’ve tried and loved:

Berry Bliss

Swap the raspberry jam for a mixed‑berry preserve (blueberries, blackberries, and strawberries). The varied colors create a stunning visual effect, and the different fruit notes add complexity. The tartness of blackberries pairs especially well with the dark chocolate glaze.

Coffee Crunch

Add a tablespoon of finely ground espresso to the chocolate glaze and sprinkle toasted almond slivers on top. The coffee’s bitterness deepens the chocolate flavor, while the almonds provide a satisfying crunch that contrasts the soft sponge.

Citrus Zing

Incorporate a teaspoon of orange zest into the jam and a splash of lemon juice into the whipped cream. The citrus brightens the overall palate, making the dessert feel lighter and more refreshing—perfect for spring gatherings.

Nutty Caramel

Drizzle a thin layer of caramel sauce over the whipped cream before rolling, and sprinkle crushed hazelnuts on the glaze. The caramel adds a buttery sweetness, and the hazelnuts introduce a nutty aroma that complements the chocolate beautifully.

White Chocolate Dream

Replace the dark chocolate glaze with melted white chocolate mixed with a hint of vanilla bean. This version is sweeter and pairs wonderfully with a raspberry‑orange jam for a festive twist. It’s a crowd‑pleaser for those who prefer a milder chocolate flavor.

📦 Storage & Reheating Tips

Refrigerator Storage

Cover the sliced cake tightly with plastic wrap or store it in an airtight container. It will stay fresh for up to three days in the fridge. The glaze may firm up a bit, but a quick room‑temperature sit for 20 minutes restores its glossy sheen.

Freezing Instructions

If you need to keep it longer, freeze the unglazed cake layers separately, wrapped in parchment and foil. The jam and cream can be frozen as well, but it’s best to assemble the cake after thawing. When you’re ready to serve, thaw in the refrigerator overnight, then apply a fresh glaze for the best texture.

Reheating Methods

To enjoy a warm slice, place a piece on a microwave‑safe plate and heat for 10‑15 seconds. For a more even warm‑up, preheat your oven to 150°C (300°F) and warm the slice for 5‑7 minutes, covering it loosely with foil to prevent the glaze from cracking. The secret to reheating without drying it out? Add a splash of milk to the cream layer before warming, and the moisture stays locked in.

❓ Frequently Asked Questions

Absolutely! Substitute the all‑purpose flour with an equal weight of a gluten‑free flour blend that includes rice flour, potato starch, and xanthan gum. The cornstarch already helps keep the texture light, so the cake will still be airy. Just be sure to sift the gluten‑free flour to avoid any gritty pockets.

You can absolutely use fresh raspberries, but you’ll need to cook them down with a bit of sugar and lemon juice until they reach a jam‑like consistency. Then blend them briefly for a smoother texture. Fresh fruit adds a brighter flavor, though it may be a bit more tart.

The key is to roll the sponge while it’s still slightly warm and pliable. Lightly dust the parchment with powdered sugar to reduce sticking, and roll gently but firmly. If you find cracks forming, let the sponge rest for a minute before continuing the roll.

You can, but the flavor profile will be sweeter and less complex. If you opt for milk chocolate, consider adding a pinch of sea salt or a dash of espresso powder to the glaze to balance the sweetness and give it depth.

Store the glaze in an airtight container in the refrigerator for up to a week. When you need to use it again, gently reheat it over a double boiler or in short bursts in the microwave, stirring frequently to restore its smooth, pourable texture.

Yes! Thinly sliced fresh strawberries, kiwi, or even passion fruit can replace the jam for a fresher, lighter taste. Just be sure to pat the fruit dry with a paper towel to prevent excess moisture from sogging the sponge.

Definitely. Replace the eggs with a combination of aquafaba (chickpea water) and a tablespoon of ground flaxseed for each egg. Use coconut cream instead of heavy cream, and choose a dairy‑free chocolate with cocoa butter. The texture will be slightly different but still delicious.

If stored at room temperature, the glaze can become soft after about 4‑5 hours, especially in warm climates. For longer shelf life, keep the cake refrigerated and bring it to room temperature just before serving. This preserves the glossy finish and prevents the chocolate from becoming oily.
