Blueberry chocolate cake ingredients and substitutions
💜 BLUEBERRIES – Blueberries are packed with antioxidants, vitamins, and minerals, making them an ideal choice for making a cake. Fresh blueberries are the best way to get the most out of this amazing fruit, but if you’re making the cake in the winter and can’t find fresh blueberries you can easily use frozen blueberries.
Blueberry decoration on top of the cake can be replaced with chocolate candies, chocolate-covered fruit balls, or some other fruit, like raspberries or brambles. Instead of that you can make an additional layer of jelly blueberry sauce or a simple chocolate layer.
🍪 BUTTER BISCUITS – We used french petit beurre cookies in this recipe because they will crumble very easily and the melted butter with cocoa will blend in perfectly.
Nevertheless, you can use any kind of butter cookies that are crunchy enough to grind with a food processor. Even better, replace the cookies with a mixture of dried dates and ground-roasted hazelnuts.
🍫 COCOA POWDER – will be blended together with the cookies and will give the cake a rich, chocolatey flavor. Combined with the blueberry and chocolate layer you’ll get a unique flavor that is sweet and tart.
🧀 MASCARPONE CHEESE – Mascarpone cheese is a soft, creamy Italian cheese with a mild flavor and velvety texture. It’s made from cow’s milk and is high in fat, making it rich and creamy, Fused together with the chocolate and blueberries you will create a dessert that will melt in your mouth and will be calling for more.
However, it can be replaced with any other cream cheese. Please keep in mind that the cheese should have a very mild flavor not to override the taste of blueberries and chocolate.
🍦 HEAVY WHIPPING CREAM – the whipping cream we used in the recipe is combined with blueberries and chocolate in both layers of the cake. Your cake will still taste fine using vegan whipping cream.
🧈 BUTTER – the butter in this recipe will be melted and mixed together with the crumbled cookies and cocoa powder. When chilled, this will form a sweet and quite sturdy crust that will be the first layer of your no-bake blueberry chocolate cake.
🍫 DARK CHOCOLATE – Dark chocolate contains antioxidants, minerals, and other beneficial compounds. The type of chocolate you choose is completely up to you. Let me just give you a hint, this blueberry chocolate cake recipe also works perfectly with white chocolate.
🥡 GELATINE LEAVES – They will be used to form the blueberry layer of the cake, mixed together with the mascarpone cheese and whipped cream. The gelatine leaves must be soaked in the water before mixing them in the blueberry sauce. They can be replaced with gelatine powder.
🍬 SUGAR – We used powdered sugar in the recipe because it melts faster and makes mixing with other ingredients much easier. For quite some time now we make the powdered sugar at home using a simple coffee grinder.
If you want to avoid sugar altogether, ground or powdered erythritol will be a healthy and easy substitution.
🍾 RUM – There are only two tablespoons of rum in the cookie crust. If you wish to avoid alcohol you can entirely skip the rum, However, if you wish to enhance the blueberry and chocolate taste of the cake, by adding too much rum you might just work too strongly against these two flavors.
🥛 MILK – Two tablespoons of milk are added to the cookie mixture of the cake crust. The crust gets sturdy when chilled. By adding more milk you will make the crust softer.

Recipe notes and tips
- Be patient while waiting for the chocolate layer to cool. If the layer doesn’t get solid enough when topping it with the blueberry layer, the cake will still taste great, but the two layers will probably mix together.
- Use only quality dark chocolate or chocolate chips.
- For the decoration, use only fresh and healthy-looking blueberries. The cake will taste the finest if you combine it with freshly picked wild blueberries.
- Make the blueberry chocolate cake in advance and make sure it’s served cold. It’s best to keep it in the refrigerator overnight before serving.
- You can add another thin blueberry jelly layer on top by mixing warm blueberry sauce, sugar and gelatine leaves.
Storage and freezing
Store the cake in the fridge for up to two days. It preserves best if the cake is covered.
You can freeze the cake without decoration unless the decoration contains only chocolate balls and no fresh fruit. Cover it with plastic foil or cake cover and store it in the freezer for up to 2 months. Thaw it overnight in the refrigerator and serve cold.
Blueberry chocolate cake FAQs
Yes, the cake can be easily made for people on the keto diet. Replace the powdered sugar with erythritol and make the cake with only two layers of blueberries and chocolate. The keto version tastes delicious.
If you want to make a blueberry chocolate vegan cake:
- Make the crust from dates and ground hazelnuts
- Use vegan heavy cream and vegan cream cheese instead of mascarpone both, chocolate and blueberry layer
- Replace the gelatine leaves with vegan gelling powder
It’s even easier to melt chocolate chips than pieces of chocolate. Make sure you buy quality dark chocolate chips; it works best.
If the cake is too soft it means it’s not chilled enough. Put the cake back in the fridge, preferably overnight and serve cold.
To make the chocolate taste of the cake even more flavorful, you can add three spoons of (cooked) coffee or a spoonful of coffee powder to the crust instead of milk.
It depends on the type of chocolate you eat. Any chocolate that contains a lot of sugar might add to the acidity in your body, meaning you will be feeding and enabling bacteria to spread even more. Dark chocolate (at least 75% or more) usually doesn’t contain a lot of sugar so it won’t affect the aggravated nerves in your throat getting worse.
