ThisGluten-Free Vegan Chocolate Mousse Cake is the best secretly healthy yet seriously indulgent dessert: a moist, fluffy chocolate sponge, topped with a silky, melt-in-your-mouth chocolate mousse and a velvety chocolate ganache. It's super chocolatey, rich and creamy and sweet but not sickly! It's super easy to make and refined sugar free too.

For the base, I used my go-to chocolate sponge recipe- it's easy to make, requires just one bowl and familiar ingredients, and is versatile too.

The mousse layer was inspired by my Chocolate Sweet Potato Buttercream- it's easy to make, uses inexpensive ingredients and you honestly can't taste the sweet potatoes at all! Their naturally creamy texture makes them the perfect base for a luxurious chocolate mousse that doesn't leave you feeling unwell afterwards.

The dark chocolate ganache layer is the perfect way to finish off the cake as it adds an extra level of indulgence.

Ingredients

For the chocolate sponge:

  • 30 g ( cup) coconut oil (or sub olive or vegetable oil)
  • 125 ml (½ cup) unsweetened almond milk (or any other plant-based milk)
  • 1 teaspoon apple cider vinegar (ensure gluten-free if necessary)
  • 6 tablespoons maple syrup (or sub any other sweetener)
  • 1 teaspoon vanilla extract
  • Pinch salt
  • 75 g ( cup) ground almonds (almond meal) *
  • 75 g ( cup) gluten-free flour blend (or sub plain flour if not gluten-free)
  • 1 heaped teaspoon baking powder (ensure gluten-free if necessary)
  • ¼ teaspoon bicarbonate of soda (baking soda)
  • 25 g (¼ cup) cocoa powder

For the chocolate mousse:

  • 400 g (14 oz) sweet potatoes (2 medium-sized sweet potatoes)
  • 2 tablespoons cocoa powder
  • 1 teaspoon vanilla extract
  • Pinch salt
  • 3 tablespoons maple syrup (or sub any other sweetener)
  • 1 teaspoon coconut oil

For the chocolate ganache:

  • 60 g (2 oz) dark chocolate ** (ensure vegan/refined sugar free if necessary)
  • 7 tablespoons unsweetened almond milk (or any other plant-based milk)

Instructions

For the chocolate sponge:

  • Preheat oven to 180 degrees Celsius (350 degrees Fahrenheit).

  • Place the coconut oil in a large bowl and melt over a saucepan of boiling water or in the microwave (skip this step if using any other oil).

  • Once melted, add the milk to the same bowl along with the vinegar, maple syrup, vanilla, salt and ground almonds.

  • Sift in the flour, baking powder, bicarbonate of soda and cocoa powder.

  • Mix well, adding a tiny splash more milk if it’s looking too dry.

  • Place the mixture into a greased springform baking tin lined with baking paper (I used a 7inch/18cm springform baking tin).

  • Bake in oven for around 15 minutes until risen slightly and an inserted skewer comes out clean.

  • Once out of the oven, leave the sponge in the tin to cool completely before applying the mousse.

For the chocolate mousse:

  • Cook the sweet potatoes by boiling, steaming or roasting them until very soft and tender.

  • Discard any skins, and add to a food processor or blender (or hand-held blender) along with all other ingredients.

  • Whizz until completely smooth.

  • Taste and adjust ingredients as necessary – add more maple syrup for sweetness, more cocoa powder for chocolate flavour etc.

  • Leave to cool before using for the cake.

  • Once the sponge has cooled, keep it in the baking tin and spread the chocolate mousse over it.

For the chocolate ganache:

  • Melt the chocolate either over a bain-marie or in the microwave, add the almond milk and mix well.

  • Still keeping the cake in the baking tin, pour the chocolate ganache over the top of the mousse layer.

  • Place in the fridge for at least a few hours until everything is set.

  • Once the chocolate ganache has set, decorate if desired.

  • Ensuring that everything has set properly, remove the cake from the springform tin and transfer onto a plate or cake stand before slicing.

  • Tastes best when fresh, but keeps covered in the fridge for up to a few days.
