Mandarin Orange Mousse Cake with Citrus and Chocolate Ganache

This fluffy and light mousse cake is the most delicious mandarin cake ever! This elegant cake is made with a classic sponge cake, flavors of mandarin, then topped with a simple chocolate ganache and loads of mandarins.


Every bite of this sweet cake melts in your mouth. This mandarin cake can be made year-round, but we like to enjoy it mostly during the winter season for all of the holiday parties when mandarins are in season. In my childhood, we would have loads of mandarins at home during the winter. They brought us the fresh citrusy flavors that oranges and lemons couldn’t (since they weren’t seasonal). There is so much to do with mandarins. We would always have them available and give them out to friends, serve at the dessert table, and put them in this delicious mandarin mousse cake!

This mandarin cake is topped with a delicious, smooth chocolate ganache. It has only two ingredients and is super easy to make! As a fun decor option, I dipped my mandarins in the delicious chocolate ganache, too. That makes them a delectable treat to top the cake with.


How to Make A Sponge Cake

The classic sponge cake base is made with just a few ingredients that are usually in my pantry. It’s one of the recipes that I use in many of my cake recipes, it’s simply a no-fail recipe. When making the sponge cake, make sure to first whisk the eggs and sugar well, until they’re almost white in color and are voluminous. Add the dry ingredients by folding gently from the bottom of the bowl. To make the sponge cake moister after it’s baked, cooled down, and sliced, I like to use a simple syrup. I make this by mixing a teaspoon of sugar and a couple of tablespoons of water, then gently pouring the syrup onto the cake, especially on the edges.
