Ingredients You’ll Need

You don’t need fancy ingredients to make this Chocolate Roll Cake with Raspberry Mousse Filling, but each item plays a critical role in the taste, texture, and even the look of the finished dessert. This cake leans on pantry staples, fresh cream, and real chocolate to create bakery-level results right in your own kitchen.

• Gelatin powder: Essential for helping the raspberry mousse set to the perfect sliceable-yet-airy consistency.
• Heavy whipping cream (divided): Creates both the dreamy mousse filling and the silky ganache; use the real thing for best results.
• Chopped white chocolate or white chocolate chips: Adds richness to the mousse and lends creamy sweetness.
• Raspberry jelly: Amplifies the berry burst in the mousse and adds a fruity layer inside the cake roll.
• Large eggs: Provide structure and tenderness in the sponge cake; separating them is the trick for that signature fluffiness.
• Egg yolk: Deepens the cake’s color and flavor, making each bite richer.
• Sugar (divided): Sweetens both the cake and the filling; measuring carefully ensures balance.
• Milk: Keeps the sponge moist and helps blend the flavors seamlessly.
• Mayonnaise: The secret ingredient for supremely tender cake—it’ll disappear into the batter leaving only its wonderful effect.
• Cake flour: Gives the roll cake that delicate, light crumb perfect for rolling without cracking.
• Natural unsweetened cocoa powder: Delivers deep chocolate flavor and a dramatic, dark color to the sponge.
• Powdered sugar: Not just for sweetness, but for dusting and preventing the cake from sticking to the towel when rolling.
• Semi-sweet chocolate or chocolate chips: The heart of the shiny ganache that finishes the cake with a rich, chocolate shell.
• Fresh raspberries: Bright, juicy decoration that highlights the mousse and makes each serving look irresistible.

How to Make Chocolate Roll Cake with Raspberry Mousse Filling

Step 1: Bloom the Gelatin

Start by sprinkling the gelatin powder over a tablespoon of water in a small bowl. Let it sit undisturbed for five minutes. This step ensures your raspberry mousse won’t run or leak—it’s the difference between a picture-perfect swirl and a messy surprise!

Step 2: Heat the Cream

Microwave a quarter cup of the heavy whipping cream until hot but not boiling—about 30 seconds does the trick. Pour this straight over your bloomed gelatin, stirring gently to dissolve the granules fully.

Step 3: Melt with White Chocolate

Place your chopped white chocolate in a small bowl and pour the hot cream-gelatin mixture over the top. Let it sit for a minute to soften the chocolate, then stir until smooth and glossy. If you spot stubborn bits, a quick 30 seconds in the microwave will finish melting everything. Allow this mixture to cool completely—pop it in the fridge briefly if needed.

Step 4: Whip the Cream

Take the remaining heavy whipping cream and whip it with a stand mixer or hand mixer until it forms stiff peaks. This is crucial for an airy mousse! Gentle folding keeps all that precious air inside.

Step 5: Combine for Raspberry Mousse

Gently fold the cooled white chocolate mixture and raspberry jelly into the whipped cream. You want everything luxuriously smooth, streak-free, and still fluffy. Refrigerate the mousse while you tackle the rest of the Chocolate Roll Cake with Raspberry Mousse Filling.

Step 6: Prepare and Bake the Cake

First, preheat your oven to 350°F (177°C), and line a 9×13-inch baking sheet with parchment paper, giving it a quick spritz of cooking spray to guarantee the cake releases cleanly.

Step 7: Separate Eggs and Beat Whites

Carefully separate the eggs, placing whites in one large mixing bowl and yolks (with one additional yolk) in another. Whip the egg whites with half the sugar until stiff peaks form—this gives the cake its signature lift and lightness.

Step 8: Beat Yolks and Mix Cake Batter

In a different bowl, whisk the egg yolks and the remaining sugar until the mixture is thick and pale yellow. Add the milk and mayonnaise, blending until smooth. Then sift in the cake flour and cocoa powder, mixing until just combined.

Step 9: Fold and Finish the Batter

Gently fold in half of the whipped egg whites until mostly incorporated, then add the rest, folding carefully to keep the batter airy. Don’t rush; a few minutes of mindful folding pay off in a cake that rolls up like a dream.

Step 10: Bake the Sponge

Pour the batter gingerly into your prepped pan, smoothing it into an even layer. For the softest sponge, place a pan of hot water in your oven’s lower rack, then bake the cake on the middle rack for about 13 minutes or until a toothpick comes out clean. The steam keeps your cake wonderfully moist and pliable.

Step 11: Cool and Prep for Rolling

Let the cake cool in its pan on a wire rack for 15–20 minutes. If you need to step away for a bit longer, just cover the pan with a towel to protect tenderness.

Step 12: Roll and Fill

Liberally dust a clean kitchen towel with powdered sugar and invert the completely cooled cake onto it. Gently peel off the parchment paper and trim the cake edges for neatness. Spread raspberry jelly across the surface, followed by an even layer of your raspberry mousse, saving half a cup for later decorating. Use a thinner mousse layer toward the short edge so the roll ends up tidy and even.

Step 13: Roll the Cake

Using the towel as a guide, carefully roll the cake into a snug log, taking care not to squeeze out the filling. This is where the flexibility of your sponge pays off! Move the finished roll to a wire rack set over a baking sheet, ready for its final, gorgeous coat.

Step 14: Make and Pour Ganache

Bring the remaining heavy cream just to a simmer in a small saucepan. Pour over your chopped semi-sweet chocolate and let it sit undisturbed for two minutes. Mix until smooth, glossy, and irresistible, then pour this ganache over the cake roll, letting it cascade luxuriously down the sides. Chill the cake in the fridge for at least two hours to set.

Step 15: Decorate to Finish

Transfer the reserved mousse to a piping bag, using a star tip for a pretty flourish. Pipe generous rosettes along the top of your Chocolate Roll Cake with Raspberry Mousse Filling, and add a scattering of fresh raspberries for that final, luscious touch.

How to Serve Chocolate Roll Cake with Raspberry Mousse Filling

Garnishes

When it’s time to slice and serve, don’t underestimate the power of a beautiful garnish! Reserve extra fresh raspberries and maybe a light dusting of powdered sugar over the ganache. Mint leaves offer a refreshing pop of green and a slight contrast to the deep chocolate tones.

Side Dishes

This rich, fruity dessert pairs beautifully with a simple scoop of vanilla ice cream or a dollop of freshly whipped cream. For a more elegant plating, serve thin slices alongside a few macerated raspberries or a drizzle of sweet raspberry coulis to echo the flavor theme.

Creative Ways to Present

For a show-stopping display, arrange slices of the Chocolate Roll Cake with Raspberry Mousse Filling on a long platter, alternating the direction of each slice for visual impact. Individual mini roll cakes are always a hit for parties—just use a smaller cake pan and repeat the filling and ganache steps! If you’re feeling ambitious, add edible gold leaf or chocolate curls on top for a touch of luxury.

Make Ahead and Storage

Storing Leftovers

To keep your Chocolate Roll Cake with Raspberry Mousse Filling fresh, wrap any leftover slices tightly in plastic wrap and store them in an airtight container in the fridge. The cake stays moist and the mousse keeps its lovely texture for up to four days—just be sure to keep everything well-sealed.

Freezing

This cake freezes surprisingly well! Once set, you can wrap the entire roll (or individual portions) in plastic wrap followed by a layer of foil. Freeze for up to one month. Thaw overnight in the refrigerator before serving for best flavor and consistency.

Reheating

Since this cake is served cold or at room temperature, there’s no need to reheat. If you like your ganache slightly soft, let the cake rest at room temperature for 20 minutes before serving. Avoid microwaving, as this may compromise the mousse’s delicate texture.

FAQs

Can I use frozen raspberries in the mousse filling?

Absolutely! Use frozen raspberries to make your own simple raspberry jelly, or gently fold thawed berries (well-drained) into the store-bought jelly for bursts of real fruit in your Chocolate Roll Cake with Raspberry Mousse Filling.

What if I don’t have cake flour?

No cake flour? No worries! Substitute all-purpose flour by removing two tablespoons from your half-cup and replacing them with two tablespoons of cornstarch. Sift well for that airy texture.

Can I make the cake roll ahead of time?

Yes—you can prepare the Chocolate Roll Cake with Raspberry Mousse Filling a day in advance. Just store (undecorated) in the fridge, then finish with ganache and garnishes before serving. This actually helps the flavors meld together beautifully.

How do I keep the cake from cracking?

Roll the cake while it’s still slightly warm and pliable, using plenty of powdered sugar on the kitchen towel. If the cake cools too long, it can dry out and crack. Don’t skip the step with the towel—this really does make all the difference!

Is there a gluten-free option for this recipe?

You can enjoy a gluten-free version by swapping cake flour for your favorite 1:1 gluten-free baking blend. Just ensure the mix contains a little xanthan gum for hold, and check that your cocoa powder is certified gluten-free.
