Easy Chocolate Cranberry Mousse Cake

This Chocolate Cranberry Mousse Cake is one of the best cranberry cakes you can make. It starts with a fudgy, moist chocolate brownie base, topped with a thin layer of bright cranberry sauce for a lovely tart contrast. A light and creamy cranberry mousse ties everything together. Finished with chocolate decorations and sugar-coated red currants, it’s an elegant, festive dessert that’s surprisingly easy to make and enjoy.

It’s not overly sweet, it is light and creamy, with that melt-in-your-mouth texture that makes it hard to stop at one slice. The texture, with its mix of dense brownie, smooth mousse, and juicy cranberries, makes every bite feel special. If you love chocolate but crave something with a twist, this cake is the perfect way to enjoy both.

How to make chocolate cranberry mousse cake

Begin by preparing the cocoa brownie base. Preheat your oven to 320°F (160°C). Grease and line an 8-inch (20 cm) springform pan with parchment paper to ensure easy release later.

In a medium bowl, whisk together the egg and sugar until well combined and slightly pale. Add in the oil and vanilla extract, whisking until smooth and glossy.

Sift in the flour, salt, and cocoa powder, then gently whisk again until the batter is fully incorporated and no dry streaks remain.

Pour the brownie batter into the prepared pan, spreading it evenly with a spatula. Bake for 20–25 minutes, or until a toothpick inserted into the center comes out clean or with just a few moist crumbs attached.

Allow the brownie to cool completely in the pan while you prepare the next layers.

Next, prepare the cranberry sauce, which will serve as the base flavor for your mousse.

In a small saucepan, combine the cranberries, sugar, and lemon juice. Set over medium heat, bring to a gentle boil, and cook for about 10 minutes, stirring occasionally, until the berries burst and the mixture thickens slightly.

Remove from the heat and press the mixture through a fine sieve to remove any seeds or skins. Set the smooth cranberry purée aside.

Meanwhile, dissolve the gelatin in a small bowl of cold water and let it swell for 5–10 minutes. Once ready, stir the swollen gelatin into the warm cranberry sauce until fully dissolved. Let this cranberry mixture cool to room temperature before continuing.

Reserve 4 tablespoons of cranberry sauce and spread them over the brownie. Place a cake ring around the cooled brownie base and line the inside with an acetate sheet for clean edges.

How to make the cranberry mousse

In a chilled bowl, whip the whipping cream until soft peaks form, it should be airy but not stiff. Gradually fold in the cooled cranberry mixture, mixing gently until the mousse is smooth and evenly colored.

Pour the cranberry mousse over the brownie, smoothing the top with a spatula to create an even surface.

Refrigerate for at least 4–6 hours, or preferably overnight, until the mousse is fully set and firm to the touch.

Finally, decorate the cake. Garnish with chocolate decorations, sugar-coated cranberries, or fresh red currants for a festive, elegant finish.
