Why You'll Love This Recipe
About the Ingredients
4 large eggs, separated
Room temperature eggs whip up better. If you're in a hurry, place them in warm water for 5 minutes.
1/2 cup (100g) granulated sugar, divided
Use fine sugar for faster dissolving. Organic cane sugar works too.
1/3 cup (40g) all-purpose flour
Cake flour yields a tenderer crumb, but AP flour is fine. Sift before using.
2 tablespoons unsweetened cocoa powder, plus extra for dusting
Dutch-processed cocoa gives a deeper flavor. If using natural, no problem.
1/2 teaspoon baking powder
Ensure it's fresh for proper rise. You can substitute with 1/4 tsp baking soda + 1/2 tsp cream of tartar.
1/4 teaspoon salt
Fine sea salt is best. It balances the sweetness.
1 teaspoon vanilla extract
Pure vanilla extract adds warmth. You can use vanilla bean paste for specks.
1 cup (240ml) heavy cream, chilled
Use cold cream for better whipping. For a lighter mousse, use 1/2 cup cream and 1/2 cup mascarpone.
6 ounces (170g) semisweet chocolate, finely chopped
Use good quality chocolate bars, not chips, for smoother melting. Dark chocolate (60-70%) works well.
3 tablespoons powdered sugar
For dusting the finished roll. You can also use cocoa powder mixed with powdered sugar.
Tips & Tricks
Don't overmix the batter
Fold gently until just combined to keep the sponge airy.
Roll the cake while it's warm
This prevents cracking. Use a kitchen towel dusted with cocoa powder.
Chill the mousse properly
Let it set in the fridge for at least 2 hours before serving for clean slices.
Pro Tips
Step-by-Step Instructions
1. Preheat and Prep
Preheat your oven to 350°F (175°C). Line a 15×10-inch (38×25 cm) jelly roll pan with parchment paper, leaving some overhang for easy removal.
2. Whip Egg Yolks and Sugar
In a medium bowl, beat egg yolks with 1/4 cup (50g) sugar until pale and thick, about 2-3 minutes. Stir in vanilla extract.
3. Whip Egg Whites
In a clean bowl, beat egg whites with salt until soft peaks form. Gradually add the remaining 1/4 cup (50g) sugar, beating until stiff, glossy peaks form, about 4-5 minutes.
4. Fold Dry Ingredients
Sift flour, cocoa powder, and baking powder over the yolk mixture. Fold gently until almost combined. Then fold in the egg whites in three additions, being careful not to deflate the batter.
5. Bake the Sponge
Spread the batter evenly into the prepared pan. Bake for 10-12 minutes, until the top springs back when lightly touched and the edges start to pull away from the pan.
6. Roll the Sponge
While the cake is still warm, dust a clean kitchen towel with cocoa powder. Invert the cake onto the towel, peel off the parchment, and roll the cake up with the towel from a short end. Let cool completely on a wire rack.
7. Make the Chocolate Mousse
Melt the chopped chocolate in a heatproof bowl over simmering water, stirring until smooth. Let cool slightly. In a separate bowl, whip the heavy cream to soft peaks. Gently fold the melted chocolate into the whipped cream until fully incorporated.
8. Fill and Roll
Unroll the cooled cake. Spread the mousse evenly over the cake, leaving a small border. Carefully re-roll the cake without the towel. Place seam-side down on a serving platter.
9. Chill and Serve
Refrigerate the roll for at least 2 hours to set. Before serving, dust with powdered sugar. Slice with a sharp knife.
Delicious Variations
Mocha Mousse Roll
Add 1 teaspoon instant espresso powder to the melted chocolate for a coffee kick.
Raspberry Swirl Roll
Dollop raspberry jam over the mousse before rolling for a fruity twist.
Peppermint Bark Roll
Add 1/2 teaspoon peppermint extract to the mousse and top with crushed candy canes.
How to Store Chocolate Mousse Roll Cake
Refrigerator
Store in an airtight container in the fridge for up to 3 days.
Freezer
Wrap tightly in plastic wrap and foil; freeze for up to 1 month. Thaw in the fridge overnight.
Reheating
Serve chilled or at room temperature. No reheating needed.
Frequently Asked Questions
Q: Why did my cake crack when rolling?
Cracking occurs if the cake is overbaked or rolled when too cool. Roll it while still warm, and don't overbake—check at 10 minutes.
Q: Can I use a different pan size?
Yes, but adjust baking time. Use a similar area, like a 9×13-inch pan; bake for 12-15 minutes. Thinner cakes roll easier.
Q: Can I make this ahead of time?
Absolutely! Make it a day ahead and keep it refrigerated. It actually slices cleaner after chilling overnight.
Q: How do I get clean slices?
Use a sharp knife dipped in hot water and wiped dry between cuts. This prevents the mousse from smearing.
Q: Can I substitute the heavy cream?
You can use full-fat coconut cream for a dairy-free option, but the texture will be slightly different.
