A homemade chocolate fruit roll is a true classic that can turn an ordinary tea time into a little celebration. The thin cocoa-based sponge cake, enhanced with a pinch of cinnamon, fills the kitchen with a warming aroma while it bakes, and its texture turns out wonderfully elastic and airy. The secret to its harmonious flavor lies in the contrast: the sweetness of the batter and the tenderness of the smetana (sour cream) frosting meet the refreshing tartness of a natural apple-lemon purée. This combination not only refreshes the palate but also makes the dessert less cloying, which is especially appreciated by lovers of well-balanced homemade treats.
An appetizing chocolate roll with a tender fruit filling and crunchy nuts is the perfect addition to tea time.

How to Make the Chocolate Fruit Roll
Let’s prepare the batter. Whisk together the dry ingredients: cake flour, baking powder, ground cinnamon, and cocoa powder. Mix the dry ingredients with a spoon or a whisk.
Mix the dry components: flour, cocoa, cinnamon, and baking powder for an aromatic sponge cake.
Crack large eggs into a mixer bowl. Add powdered sugar. You can add a pinch of fine salt to balance the sweetness.
Crack the eggs into the mixer bowl and add powdered sugar to create a fluffy base.
Whip the eggs with powdered sugar for 10 minutes, adding vanilla extract if desired. You should get a fluffy, airy foam, light as a cloud.
Whip the mixture for about 10 minutes until it forms a thick and light foam.
Sift the dry ingredients into the bowl, rubbing any cocoa powder lumps through the sieve with a spoon.
Carefully sift the dry mixture into the whipped eggs to avoid lumps.
Fold the batter gently to make it smooth while preserving its airy volume.
Mix the batter with gentle movements, trying to preserve the airy volume.
Pour the batter onto a baking sheet lined with parchment paper and spread it into a thin layer. Use high-quality parchment, preferably silicone-coated, as it will be hard to peel the sponge off cheap paper. It is best to grease any paper with a drop of neutral vegetable oil or a quick coat of cooking spray. Bake the sponge cake in an oven preheated to 180°C (350°F) for 10-12 minutes.
Spread the batter evenly over high-quality parchment before sending it into the oven.
While the sponge is baking, make the filling. Pass the apples and lemon through a meat grinder or process the fruits in a blender. The lemon will mix with the apple and prevent it from browning.
Use fresh apples and a lemon for the filling, which will preserve the bright color of the fruits.
Remove the baked sponge cake from the oven.
Remove the hot sponge cake from the oven—it should be springy and aromatic.
Roll it up immediately along with the parchment paper and let it sit for a few minutes.
Roll up the hot sponge cake along with the paper so it 'remembers' the shape.
Meanwhile, mix the processed fruits with sugar.
Mix the processed fruits with sugar until smooth.
Unroll the cake and spoon the fruit mixture over it. Spread the fruit purée evenly across the entire sponge. Roll the cake back up and wrap it in the parchment paper. Place it in the refrigerator or freezer to cool quickly.
Spread the apple-lemon purée evenly over the entire surface of the sponge cake.
Place cold, high-fat smetana (sour cream, 26-30% fat) into a tall mixing beaker. Add powdered sugar and sour cream stabilizer. Whip for a few minutes until you get a thick frosting. Coat the cooled roll with the sour cream frosting.
Coat the cooled roll with a thick frosting made of whipped sour cream and powdered sugar.
Melt the dark chocolate and transfer it to a piping bag with a fine tip. Drizzle the melted chocolate over the roll. Finely chop the walnuts with a knife and sprinkle them over the roll before the chocolate sets.
The final touch is thin drizzles of melted chocolate and chopped walnuts.
To let the chocolate fruit roll fully reveal its flavor, make sure to give it time to 'rest' in a cool place. After a few hours in the refrigerator, the sponge cake will soak up moisture from the fruit filling, becoming even softer and more luscious. When serving, slice the roll thickly and pair it with a scoop of vanilla ice cream or a sprig of fresh mint—this will add a touch of elegance and highlight the dessert's fruity notes. If you want to experiment, try replacing the apples with ripe pears or adding a little berry jam to the filling for a richer color. It is best to store the finished cake in a tightly sealed container so the smetana (sour cream) frosting doesn't absorb foreign odors. This recipe is an excellent base for culinary creativity, allowing you to create a new flavor every time while keeping the perfect chocolate foundation.
