Graham always gets a good birthday cake, since his birthday is in summer – this year it was this vegan, one-bowl, chocolate raspberry cake with a coconut milk ganache. It looks a bit fancy, doesn’t it? But it’s really simple, I promise, even the icing. I just tossed it on there and made some swoops with a spoon.
It’s a basic vegan chocolate cake, made with light spelt flour, cocoa powder, non-dairy milk, olive oil, and a little coconut sugar. I adapted it from my pumpkin and chocolate layer cake and reduced the sugar a bit. Half a cup of coconut sugar for a whole cake is pretty all right, I think.
The cake has a nice light texture and deep chocolate flavour, with some raspberries tossed in halfway through filling the tin with the batter for a berry surprise in the centre. This lightens an otherwise rather rich cake, and makes it into a properly summery dessert.
- Light (sifted) spelt flour
- Coconut sugar
- Cocoa powder
- Baking powder
- Baking soda
- Sea salt
- Non-dairy milk
- Olive oil
- Vanilla extract
- Dark chocolate
- Full-fat coconut milk
Preheat the oven and grease a springform pan with coconut oil. Add the flour, sugar, cocoa, baking powder, baking soda, and salt to a large bowl and whisk it very well – no lumps! Once it’s mixed, add the milk, oil, and vanilla, then stir until just mixed (don’t over-mix) and there aren’t any visible streaks of flour.
Pour about half the batter into the prepared tin, then scatter a generous handful of raspberries over it. Top with the remaining batter, then bake for about 45 minutes or until your cake passes the toothpick test.
It’s a single bowl method because dishes are the worst and cake shouldn’t involve more dishes than necessary, especially when hot water should be avoided at all costs during steamy summer weather. Mix, bake, cool, ice, done.
To make the ganache, place the chopped chocolate into a heatproof bowl. Heat the coconut milk in a saucepan until simmering, then pour over the chocolate. Let this sit for 30 seconds, then whisk to combine. This needs to cool fully in the refrigerator before icing the cake.
Since both the cake and the icing need plenty of time to cool fully, you might want to make them the night before you plan on serving them to ensure plenty of time for that. Warm cake means melting ganache and you don’t want that.
I need to write a whole post about this, I think, so that’ll be coming up soon. This recipe – along with these vegan chocolate tarts and chocolate hazelnut cake – uses a full can of coconut milk instead of scooping the cream from the can. It’s easier and less wasteful, and tastes just as good – if anything, it’s even easier to work with.
There’s a caveat, though, in that you need to be very certain that the coconut milk you’re using has a very high fat content. At least 65% is key. If it doesn’t specify, then stick to the safe side and scoop out the cream only. The cake linked above includes some tips on how to fix your ganache if it does turn out too thin, which will happen if you use light coconut milk or a brand that cheaps out on the amount of cream included.
Tips and Notes
The ganache is a full can of coconut milk, including the watery bit, four squares of baking chocolate, and some maple syrup. I’ve posted variations of this ganache before but this is the most streamlined & simple version yet. The trick here is to make the ganache and the cake the night before so everything has cooled down when you’re ready to assemble it.
Don’t worry about raspberries sinking to the bottom of the cake. The batter is relatively thick, and since they’re going in the middle rather than being mixed throughout, they’ll float in a nice even layer.
Make sure you’re using cocoa powder, not cocoa drink powder, which is something quite different. There should only be one ingredient. If you see anything like sugar, milk powder, etc., then it’s not for baking.
I don’t have a gluten-free substitution for this cake. A good GF blend might work, but I recommend going for a recipe that was developed specifically to be gluten free instead – like this one-bowl gluten free chocolate cake (it has a vegan option). You can, of course, use all-purpose flour in place of spelt for this recipe, and whole-wheat pastry flour works too.
Don’t have fresh raspberries? Use frozen, no problem. Strawberries, cherries, and apricots all make good alternatives, though I don’t recommend frozen strawberries here as they’re too watery. You can also leave the fruit out in a pinch and have an excellent basic vegan chocolate cake.
Olive oil can be replaced by any light-tasting liquid oil. Grape seed, avocado, and so on. I don’t like coconut oil in this cake, it makes it too heavy after cooling. Cane sugar can be used instead of coconut sugar if you prefer.

Chocolate Coconut Milk Ganache
- 100 grams (3.5 oz) dark chocolate
- 400 ml (13.5 oz.) canned full-fat coconut milk
- 2-3 tablespoons maple syrup, to taste (optional)
- 1/2 teaspoon pure vanilla extract
- Raspberries, for topping
- Preheat the oven to 175C / 350F and grease a 20cm / 8 inch spring form pan.
- In a large bowl, whisk together the flour, sugar, cocoa, baking powder, baking soda, and salt. Make a well in the centre and pour in the milk, olive oil, and vanilla. Use a wooden spoon to stir until just mixed and no streaks of flour remain.
- Pour half of the batter into the prepared spring form, sprinkle a layer of raspberries in, and top with the remaining batter. Transfer to the oven and bake for 40-45 minutes, or until a toothpick inserted into the centre comes out clean.
- Cool the cake on a rack for 15 minutes before removing the sides of the pan. Let the cake cool completely before icing.
Chocolate Coconut Milk Ganache
- Finely chop the chocolate and place it into a heatproof bowl.
- Pour the whole can of coconut milk into a small saucepan, and heat over low-medium until just simmering. Pour the hot milk over the chocolate and let it sit for 30 seconds before whisking to combine.
- Add the maple syrup and vanilla, and sweeten to taste. Let the ganache cool fully in the refrigerator (at least four hours) before icing the cake.
- To ice, make swoops with the back of a spoon, and top with a couple generous handfuls of fresh raspberries. Store leftover cake in the refrigerator for up to three days.
* You can use another light-tasting oil instead of olive, like avocado, but avoid coconut oil as it will make the cake too dense when it cools.
