Instead of coffee and cocoa, this version celebrates bright blueberry flavour, layering sponge fingers soaked in a fragrant blueberry syrup with a light mascarpone cream and a glossy blueberry sauce. The end result is soft, creamy, and beautifully sliceable, with a fruit-forward finish that feels both indulgent and refreshingly balanced.

Although this blueberry tiramisu cake looks impressive once assembled, the process itself is very straightforward. The key is breaking it down into simple components: syrup, sauce, cream, and assembly. Each step takes only a short amount of time, and there is no baking involved.
Start by making the blueberry syrup that will be used to soak the sponge fingers. Blend the blueberries using a food processor or immersion blender until completely smooth. Transfer the purée to a small saucepan and add the water, sugar, and lemon juice.
Place the saucepan over medium heat and bring the mixture just to a boil. As soon as it starts bubbling, remove it from the heat. This brief heating intensifies the blueberry flavour while keeping the colour bright and fresh. Strain the syrup through a fine sieve to remove the skins and seeds, then set it aside to cool completely. It is important that the syrup is cold before assembling the cake, as warm liquid can soften the sponge fingers too much.
Next, prepare the blueberry sauce that will be layered through the cake and used as the topping. Add the blueberries, sugar, cornflour (cornstarch), and vanilla extract to a small saucepan. Heat gently over medium-low heat, stirring constantly. As the blueberries soften, gently crush them with a spoon so the cornflour blends smoothly without forming lumps. Once everything is well combined, add the water and continue cooking, stirring continuously, until the mixture comes to a boil and thickens, which takes about 2 to 3 minutes. If you prefer a smoother sauce, use a potato masher at the end to fully break down the blueberries. Remove from the heat and allow the sauce to cool to room temperature. Transfer it to a piping bag and refrigerate until chilled, which will make layering much easier.
To make the cream, place the icing sugar, double cream, mascarpone, and vanilla extract into a large bowl. Using a hand mixer, whisk on medium speed until the mixture becomes firm, smooth, and holds its shape. This usually takes about 2 to 3 minutes. Take care not to overwhip the cream, as mascarpone can split if beaten too aggressively. Once ready, transfer the cream to a piping bag and store it in the fridge until you are ready to assemble the cake.
Place a 16 cm (6-inch) cake ring onto the serving plate you plan to use. Line the inside of the ring with a cake collar to make removal easy once the cake is set. Quickly dip each sponge finger into the cooled blueberry syrup. Do not soak them for too long, as they will continue to soften while chilling.
Arrange the dipped sponge fingers in a single, even layer across the base of the cake ring.
Pipe roughly one third of the mascarpone cream evenly over the sponge layer.
Then pipe a thin layer of blueberry sauce over the centre of the cream.
Add a second layer of syrup-soaked sponge fingers, followed by about half of the remaining cream and another thin layer of blueberry sauce. Finish with a final layer of sponge fingers, then cover evenly with the remaining cream, reserving a small amount for the rim. Use a spatula to smooth the surface.
Pipe the reserved cream around the edges of the cake to create a border. This helps keep the final layer of blueberry sauce neatly contained in the centre. Pipe the remaining blueberry sauce inside the rim and gently spread it out.
Cover the cake with cling film and refrigerate for at least 4 hours. For the best texture and cleanest slices, chilling overnight is recommended.
Once fully chilled, carefully remove the cake ring and peel away the cake collar. Decorate the sides by attaching sponge fingers vertically around the cake. This can be done simply by pressing them gently against the cream. If desired, tie a ribbon around the cake for a polished finish.
Finish by placing fresh blueberries in the centre on top of the sauce and garnish with mint leaves. Slice and serve straight from the fridge.

This blueberry tiramisu cake is everything we love in a dessert: elegant, comforting, and far easier to make than it looks. It takes the familiar structure of a classic tiramisu and refreshes it with bright blueberry flavour, making it feel modern while still deeply comforting.
One of the standout qualities of this recipe is that it is completely eggless. The mascarpone cream is light, smooth, and stable, relying on double cream rather than eggs, which makes the process simpler and more approachable. There is no tempering, no worrying about raw eggs, and no baking involved, yet the final texture is just as luxurious as a traditional tiramisu.
The layered presentation is another reason this recipe works so well. The sponge fingers soak up the blueberry syrup beautifully, softening as the cake chills while still holding their shape. The blueberry sauce adds bursts of fruit flavour between the layers, while the mascarpone cream keeps everything balanced and creamy. Each slice shows clear, defined layers, making this cake just as impressive to serve as it is satisfying to eat.
What truly sets this dessert apart is how well it fits into real-life cooking. You can prepare the components ahead of time, assemble the cake the day before serving, and let the fridge do the rest of the work. And if you enjoy fruity desserts, make sure to try my Raspberry Cottage Cheese Bars, Passion Fruit Curd Raspberry Tarts, and Cherry Cottage Cheese Ice Cream (High Protein) for more fresh, flavour-packed inspiration.

Because it is no-bake and eggless, it is also a great option when you want a stress-free dessert that still feels special.
The cake sets entirely in the fridge, which means you can prepare it the day before and focus on enjoying your guests rather than rushing around the kitchen. The flavours develop as it chills, making it even better the next day. Much like my Berry Semolina Tart, this is a dessert that rewards planning ahead and delivers consistently beautiful results.

This no-bake blueberry tiramisu cake is an elegant, eggless twist on the classic dessert. Layers of sponge fingers are soaked in blueberry syrup, then paired with a light mascarpone cream and a smooth blueberry sauce. It may look a little involved at first glance, but once you break it down, each step takes only a few minutes. Before you know it, the cake is assembled and chilling in the fridge. And once it is ready, it disappears just as quickly.
Assemble the cake: Place a 16 cm (6 inches) cake ring onto a serving plate. Line the inside of the ring with a cake collar for easy removal. Quickly dip each sponge finger into the cooled blueberry syrup and arrange them in a single layer over the base. Pipe roughly one third of the mascarpone cream evenly on top, then pipe a thin layer of blueberry sauce over the centre. Add a second layer of syrup-soaked sponge fingers, followed by half of the remaining cream and another thin layer of blueberry sauce. Finish with a final layer of sponge fingers, then cover evenly with the remaining cream, reserving a small amount for the rim. Smooth the surface with a spatula. Use the reserved cream to pipe a rim around the edges of the cake. This will help keep the final layer of blueberry sauce neatly in the centre. Pipe the remaining blueberry sauce into the middle and gently spread it out. Cover the cake with cling film and refrigerate for at least 4 hours, ideally overnight, until fully set.
Decorate and serve: Carefully remove the cake ring and peel away the cake collar. Decorate the sides by attaching sponge fingers vertically around the cake and secure with a ribbon if desired. Place fresh blueberries in the centre on top of the sauce and finish with mint leaves. Slice and serve. This cake is light, creamy, and seriously addictive.
