Chocolate Mousse Cake with Meringue

Print Friendly, PDF & Email

Dark chocolate and meringue is one of the best flavors and textures combination in desserts. The bitterness of the dark chocolate (the more cocoa solids – the better) combines perfectly with the crunchiness and sweetness of the meringue.

This chocolate mousse cake may look plain, but it hides a meringue disc in its center and the decoration is made of meringue cookies. It’s festive, super chocolatey and simply delicious. It’s a great cake for special occasions and holidays, and would also be great for upcoming Passover.
