The mango-chocolate log puts a fresh spin on the classic Christmas dessert with an exciting exotic twist. The combo of soft rum-infused sponge cake, fruity mango compote, and smooth chocolate ganache creates an irresistible flavor harmony. Each bite takes you to sunny faraway places while still keeping the festive holiday spirit alive.
The first time I made this log for my family, the mango-chocolate pairing caused a moment of complete silence around the table... right before everyone started asking for seconds! The mango brings this sunny vibe that works amazingly against the winter holiday atmosphere, making for a truly memorable taste surprise.
Key Components
- Sifted flour: This ensures an incredibly light cake without any unwanted lumps. Go for T45 flour for an even finer texture.
- Fresh eggs: Room temperature eggs work best for properly whipped whites. The egg freshness directly affects your cake quality.
- Crystal sugar: It gives structure and stability to the cake. For a more subtle flavor, swap some with homemade vanilla sugar.
- Amber rum: Its flavor works wonderfully with mango and chocolate. Pick a quality rum you'd enjoy drinking.
- Ripe mangoes: The fruity heart of this log deserves the best mangoes you can find. Look for fragrant ones with orange flesh that give slightly when pressed.
- Baking chocolate: Around 60% cocoa offers the right balance between bitterness and sweetness to complement the mango. Higher percentages would make the contrast more intense.
- Softened unsalted butter: Its texture allows perfect mixing into the ganache. Let it soften naturally at room temperature rather than microwaving to maintain its structure.
- Powdered sugar: Adding this to the ganache ensures a silky texture without any noticeable grains.

Detailed Instructions
Preparing the Cake
Start by carefully separating egg whites from yolks into two different bowls. Beat the yolks with 75g sugar until the mixture turns pale and fluffy. This key step adds air to the batter, making sure your final cake will be light.
Whipping the Whites
In another perfectly clean, dry bowl, whip the egg whites while gradually adding 25g sugar. Make sure to get a firm texture that stays on the spatula without dripping. This airy structure will be the secret to a soft, flexible cake.
Gentle Folding
Sift the flour directly onto the yolk mixture then gently fold it in with a rubber spatula. Next, add the whipped egg whites bit by bit using an upward folding motion to keep all that trapped air inside.
Just Right Baking
Spread the batter on a baking sheet lined with parchment paper, making sure it's evenly about 1 cm thick. Bake at 180°C for 10-12 minutes until the cake turns slightly golden. As soon as it comes out of the oven, cover it right away with a damp kitchen towel.

Making the Compote
While the cake bakes, cut the mangoes into small, even cubes. Cook them in a pan with a tablespoon of sugar and a few drops of lemon juice. Let them simmer on low heat until they reach a thick but still slightly fluid consistency.
Creating the Ganache
Melt the chocolate in a double boiler, making sure the water doesn't touch the bottom of the bowl. Once melted, let it cool for a few minutes before adding small pieces of softened butter. Add the sifted powdered sugar and whisk vigorously until smooth and shiny.
Careful Assembly
After the cake has completely cooled, lightly brush it with rum. Then spread the cooled mango compote, leaving about a centimeter free at the edges. Carefully but firmly roll the cake starting from the shorter side, using the parchment paper to help you.
Elegant Finishing
Cover the entire log with chocolate ganache using an offset spatula. For the traditional look, make grooves with a fork to mimic tree bark. Chill for at least 2 hours before serving so all the flavors can blend perfectly.
I've fallen in love with the mango compote texture in this log. Unlike the curd often used in pastries, it keeps small fruit chunks that burst in your mouth for a more authentic taste experience. My daughter, who was initially skeptical about mixing mango and chocolate, has been asking for seconds ever since her first taste three years ago.

Tasty Variations
For an even more exotic version, mix a teaspoon of freshly grated ginger into the mango compote. Its slightly spicy flavor enhances the fruit's sweetness while adding a welcome warmth during winter. Fans of contrasting sensations can add a thin layer of crispy praline between the cake and compote, creating an extra texture dimension. If mango isn't your thing, passion fruit or pineapple work perfectly as substitutes while keeping the tropical vibe of this festive dessert.
Festive Presentation
Make your log even more beautiful by adding fresh fruit just before serving. Arrange some thin mango slices on top, along with mint leaves for a pop of color. Dark chocolate shavings made with a vegetable peeler add an elegant graphic touch. For extra wow factor, lightly dust with edible gold powder to catch the candlelight during your holiday meal, creating a truly magical atmosphere around your creation.
Best Storage
Ideally make your log the day before or the morning you plan to serve it. Keep it in the fridge, covered with a pastry dome or plastic wrap to prevent it from picking up fridge smells. Take it out about 30 minutes before serving so the flavors can fully shine, as cold dulls the taste. If you want to get ahead, the cake can be made and frozen flat up to two weeks in advance. The mango compote also freezes really well in an airtight container for up to a month.

I'll never forget the first time I made this log for a family Christmas Eve dinner. My relatives, usually pretty stuck on traditions, first looked curiously at this tropical twist on a holiday classic. One bite was all it took to win them over, and since then, this mango-chocolate log has become our new Christmas tradition. What really touches me is how it brings together traditional holiday spirit with flavors from far away places, just like our modern families that grow and change while keeping their roots.
