Chocolate and cherry ... quite possibly the best combination on earth. This recipe may not include the alcohol-soaked cherries and Kirschwasser of a true Black Forest cake, but it's definitely not lacking in flavor. Some might say that chocolate mousse is not a component of a true Black Forest cake, but it should be! This combination of chocolate cake, chocolate mousse, cherries, and coconut whipped cream is going to win you over — we promise.
Black Forest Chocolate Mousse Cake [Vegan]
For the Chocolate Cake:
- 3/4 cup, plus 1 1/2 tablespoons all-purpose flour
- 1/3 cup granulated sugar
- 1/4 teaspoon teaspoon
- 3/4 teaspoon baking powder
- 3/4 teaspoon baking soda
- 3 1/2 tablespoons coconut oil
- 3/4 cup boiling water
- 1/3 cup Dutch process or regular cocoa powder
- 3 tablespoons ground flax seeds
- 4 tablespoons hot water
- 1 teaspoon vanilla extract
For the Chocolate Mousse:
- 4 ounces vegan semi-sweet chocolate
- 2 tablespoons hot water or brewed coffee
- 1 teaspoon vanilla extract
- 1/4 cup aquafaba (liquid from a can of chickpeas)
- 2 tablespoons granulated sugar
- 1/4 teaspoon cream of tartar
- 1 15-ounce can full-fat coconut milk, refrigerated overnight
For the Topping:
- Cherry pie filling
- Shaved chocolate
- Coconut whipped cream
To Make the Cake:
- Read notes prior to beginning.
- Combine ground flax seeds with the 4 tablespoons of hot water and whisk smooth.
- Let stand for at least 5 minutes to thicken to a paste.
- Combine the melted coconut oil, 3/4 cup boiling water, and cocoa powder together and whisk smooth.
- Add the flax meal and the vanilla extract, then whisk smooth.
- Sift the flour, sugar, baking powder, and baking soda with the salt into the chocolate mixture and whisk smooth.
- Pour batter into a greased and parchment-lined 1/4 sheet cake pan (or a 9x13-inch pan) and bake immediately in a preheated 350°F oven for approximately 18-20 minutes or until it springy to the touch when you gently press the center.
- Cool cake in the pan for about 20 minutes while you prepare the chocolate mousse recipe.
To Make the Chocolate Mousse:
- Reduce the aquafaba by bringing it to a boil in a small sauce pan, let it boil for 3 minutes. Cool completely in the refrigerator.
- Meanwhile, open the can of coconut milk that has been refrigerated overnight and carefully scoop out the fat that is on top and place in a mixer with a whip attachment. Use the coconut liquid for something else (like a smoothie or a recipe that calls for coconut water)
- Whip the coconut cream to stiff peaks and reserve in the refrigerator.
- Melt the chocolate in a large bowl over a double boiler or in a microwave-safe bowl.
- Add the warm brewed coffee to the melted chocolate all at once while whisking vigorously to incorporate well.
- Whip the cold aquafaba to stiff peaks while adding the sugar and cream of tartar.
- Take a small portion of the aquafaba meringue and fold into the chocolate mixture to lighten.
- Fold the whipped coconut cream into the mousse then refrigerate the entire mixture until it is firm or until needed.
- To assemble, line each cake ring with a food-grade acetate strip. Start by cutting circles of cake that are the exact same size as the ring.
- Add a cake circle to the very bottom of the ring. Follow with cherry pie filling, a layer of chocolate mousse, and then repeat until done. Do not overfill.
- Set in the freezer for at least 30 minutes, then remove your cake from the rings. Top each cake with whipped coconut cream and a cherry.
- See notes about cake sizes if you want to make a full cake.
To make individual cakes, you need stainless steel cake rings or 2 1/2-inch PVC pipes that can be found at most hardware stores. Line each pipe with food-grade acetate strip. You could also make the cake in a 7-inch cake pan.
