It is cooked when an inserted skewer comes out of the cake clean.
Turn cake out onto a wire rack and leave to cool completely.
Once the cake has completely cooled, trim top of cake to make it flat and even. Then cut the cake into three even layers.
Place the bottom layer of the mud cake on a suitably sized cake board or serving plate/cake stand. If using a cake stand, please note that this cake must be kept in the fridge.
Place ⅓ of the whipped ruby chocolate ganache on top of the bottom layer. Spread the ganache out evenly right to the edges with an offset spatula or spoon.
Place the middle layer of the cake on top of the ganache, and then add ⅓ of the ganache on top of the middle layer. Spread out evenly as with the bottom layer.
Place top layer on top of the ganached middle layer and place remaining ganache on top of the cake. Smooth out evenly covering the top of the cake.
Smooth the ganache around the that is visible between the cake layers to create the naked cake look.
Place ruby chocolate cherries around the top of the cake for decoration.
Ruby Chocolate Cherries
While the cake is cooling make the ruby chocolate cherries. Simply melt the ruby chocolate in a small bowl. Once melted dip cherries in chocolate and place on baking paper on tray. Place cherries in the fridge to set and until needed to decorate the cake.
Whipped Ruby Chocolate Ganache
Place half (300ml) of the cream in a saucepan over a high heat and bring to the boil. Add the ruby chocolate and stir until the chocolate has melted and the mixture is smooth.
Place in the fridge to cool.
In the bowl of a stand mixer place remaining cream (300ml). Whisk until soft peaks form.
Add the chilled chocolate mixture to the cream and whisky until thick and combined. Be careful to not over mix or you will end up with ruby chocolate butter.
Ruby Chocolate GanacheThe whipped ruby chocolate ganache is the item of this recipe to watch. You don’t want to end up with ruby chocolate butter. When whipping the cream to add your ganache DO NOT over whip it, only whip until it is thickened and soft peaks (if any peaks). You will need to continue to whip in the ganache. This is where if you over whip sweet ruby butter will appear, or at least the cream will start to split.Please refer to our Complete Guide to Ruby Chocolate
