Ingredients & Substitutions
Eggs: Fresh large eggs are best. If you’re vegan, you can try using flaxseed meal (1 tbsp flaxseed + 2.5 tbsp water to replace each egg) for a similar binding effect.
Granulated Sugar: This gives sweetness and helps with the cake’s texture. For a healthier option, you can use coconut sugar or a sugar substitute like Stevia, but be aware that it may affect the taste and texture slightly.
Cocoa Powder: Unsweetened cocoa powder provides depth of flavor. If you’re short on cocoa, you can substitute with carob powder, though the flavor will differ.
Raspberries: Fresh raspberries are ideal for the filling. You can substitute with frozen raspberries, just thaw and drain excess liquid. Alternatively, strawberries or blackberries will work too!
Heavy Cream: This creates a rich mousse. For a lighter alternative, try coconut cream or whipped topping for a dairy-free version, but the flavor will change.
How Do You Roll the Cake Without It Cracking?
Rolling the cake requires some care to avoid cracks. First, always roll the cake while it’s still warm; it’s more pliable this way. Use a clean kitchen towel dusted with powdered sugar to help prevent sticking. Follow these steps:
- Invert the cake onto the towel right after baking.
- Peel off the parchment paper gently.
- Start rolling from one short side while still warm and keep the towel inside.
- Let the rolled cake cool completely. This helps it keep its shape when you add the filling.
What’s the Best Way to Make a Smooth Mousse Frosting?
For a silky chocolate mousse, pay attention to your temperature and mixing:
- Heat half the heavy cream gently before adding chopped chocolate. This allows easy melting without burning.
- Wait for the chocolate mixture to cool to room temp, then fold it gently into the whipped cream which should be whipped to stiff peaks first. This keeps your mousse light and airy.
- Take your time when folding. Use a spatula to lift and turn the mixture slowly; this prevents deflating the whipped cream.
These tips will help you create a stunning and delicious Raspberry Chocolate Swiss Roll that impresses everyone! Enjoy baking!

How Much Time Will You Need?
This Raspberry Chocolate Swiss Roll recipe requires about 30 minutes of active preparation time, plus an additional 2 hours for chilling after assembly. It’s a perfect dessert to prepare ahead of time for a gathering!
Step-by-Step Instructions:
1. Prepare the Chocolate Sponge Cake:
Start by preheating your oven to 350°F (175°C). Line a 10×15 inch jelly roll pan with parchment paper and give it a light greasing to ensure the cake comes out easily. In a large bowl, beat the eggs and sugar with an electric mixer on high speed. Keep mixing until the mixture is thick, pale, and has tripled in volume—this should take about 5 minutes. Next, sift the flour, cocoa powder, baking powder, and salt together in another bowl. Gently fold this dry mix into your egg mixture in batches to keep it airy. Finally, add the vegetable oil and vanilla extract, folding them in nicely. Pour the batter into your prepared pan, smooth the top, and bake for 12-15 minutes, until the cake springs back when touched lightly.
2. Roll the Cake:
Once the cake is baked, remove it from the oven and immediately invert it onto a clean kitchen towel that’s dusted with powdered sugar. Carefully peel off the parchment paper. Starting from one short edge, roll the cake up along with the towel into a roll. This will help prevent cracking once it cools. Allow the rolled cake to cool completely while keeping it wrapped in the towel.
3. Make the Raspberry Filling:
In a small saucepan, combine the raspberries, sugar, lemon juice, and water. Cook over medium heat, stirring occasionally, until the raspberries break down and the mixture thickens slightly, about 5-7 minutes. If you want a smoother filling, press the mixture through a sieve to remove the seeds. If you desire a thicker consistency, mix cornstarch with a little water, stir it into the raspberry sauce, and cook until it thickens. Allow it to cool completely before using.
4. Prepare the Chocolate Mousse Frosting:
Heat 1/2 cup of the heavy cream in a saucepan until it just begins to simmer. Remove it from the heat and stir in the chopped chocolate until it’s smooth. Let this mixture cool to room temperature. In a separate mixing bowl, beat the remaining 1/2 cup of heavy cream with powdered sugar and vanilla until it reaches stiff peaks. Gently fold the cooled chocolate mixture into the whipped cream until it’s fully combined and smooth.
5. Assemble the Swiss Roll:
Carefully unroll the cooled cake. Spread a thin layer of the chocolate mousse frosting evenly over the cake. Then, dollop and spread the raspberry filling over the frosting layer. Slowly re-roll the cake without the towel, making sure it stays tight. Trim the edges if you want clean slices.
6. Frost and Decorate:
Take the remaining chocolate mousse frosting and cover the outside of the rolled cake evenly. Drizzle melted chocolate over the top in thin lines for decoration. Finish off with fresh raspberries and mint leaves for a pop of color!
7. Chill and Serve:
Refrigerate the Swiss roll for at least 2 hours before slicing to let the flavors meld and the frosting set. When you’re ready to serve, use a sharp knife to slice and enjoy this delicious treat either chilled or at room temperature.
Enjoy your beautiful and delicious Raspberry Chocolate Swiss Roll!
Can I Use Different Berries for the Filling?
Absolutely! While raspberries are delightful, you can substitute with other berries like strawberries, blueberries, or blackberries. Just keep in mind that the flavor will change slightly with different fruits, but they’ll still taste delicious!
How Do I Store Leftovers?
Store any leftover Swiss roll in an airtight container in the fridge for up to 3 days. It’s best served chilled, so no need to let it come to room temperature before enjoying!
Can I Make This Recipe Gluten-Free?
Yes, you can! Substitute the all-purpose flour with a gluten-free flour blend that’s suitable for baking. Just ensure that your baking powder is also gluten-free for the best results!
What Should I Do If the Cake Cracks While Rolling?
If your cake cracks, don’t worry! Simply use extra frosting to cover the cracks when assembling and decorating. You can also consider rolling it tighter or using a slightly damp paper towel to help with flexibility next time.
