Serves 10–12 people

Preparation Time

• Cake preparation: 25 minutes
• Baking time: 10–14 minutes
• Cooling time: 1 hour
• Filling preparation: 20 minutes
• Chilling time: 2 hours
• Total time: Approximately 4 hours

Ingredients

For the Sponge Cake

• 5 large eggs, room temperature
• 150 grams granulated sugar
• 1 teaspoon vanilla extract
• 120 grams cake flour
• 20 grams cornstarch
• 1 teaspoon baking powder
• ¼ teaspoon salt
• 30 milliliters whole milk
• 30 grams unsalted butter, melted and cooled

For the Blueberry Filling

• 400 grams fresh blueberries
• 80 grams granulated sugar
• 2 tablespoons lemon juice
• 1 tablespoon lemon zest
• 2 tablespoons water
• 1 tablespoon cornstarch
• 1 tablespoon cold water for cornstarch slurry

For the Whipped Cream Filling

• 400 milliliters heavy whipping cream
• 50 grams powdered sugar
• 1 teaspoon vanilla extract

Optional Blueberry Cream Enhancement

• 3 tablespoons blueberry puree from the cooked filling
• 1 tablespoon powdered sugar

For Decoration

• Extra fresh blueberries
• Powdered sugar for dusting
• White chocolate shavings
• Mint leaves (optional)

Equipment Needed

• 10 x 15 inch jelly roll pan
• Parchment paper
• Electric mixer
• Mixing bowls
• Fine mesh sieve
• Saucepan
• Offset spatula
• Clean kitchen towel
• Cooling rack

Step 1: Prepare the Baking Pan

Preheat the oven to 180°C (350°F).

Line a 10 x 15 inch jelly roll pan with parchment paper. Ensure the paper extends slightly above the edges for easy removal. Lightly grease the parchment paper with butter or baking spray.

Preparing the pan properly is crucial because Swiss rolls are thin cakes that can easily stick and tear if the pan is not lined correctly.

Step 2: Prepare the Dry Ingredients

In a medium bowl combine:

• Cake flour
• Cornstarch
• Baking powder
• Salt

Whisk thoroughly for at least one minute. This distributes the baking powder evenly and aerates the flour mixture.

Sift the mixture twice. A well-sifted flour mixture contributes significantly to a light and tender sponge.

Set aside.

Step 3: Prepare the Egg Mixture

Place the eggs into a large mixing bowl.

Beat on medium speed for about 1 minute until slightly foamy.

Gradually add the sugar while mixing continuously.

Increase the speed to high and beat for 6–8 minutes.

The mixture should become:

• Very pale
• Thick
• Fluffy
• Nearly triple in volume

When the whisk is lifted, the batter should fall in ribbons that remain visible on the surface for several seconds.

Add the vanilla extract and mix briefly.

This stage is one of the most important steps because the sponge relies heavily on trapped air from the whipped eggs.

Step 4: Fold in Dry Ingredients

Add the sifted flour mixture in three separate additions.

Use a large spatula.

Fold gently using upward and downward motions.

Avoid stirring aggressively.

Continue folding only until no dry flour remains visible.

Overmixing can deflate the batter and produce a dense cake.

Step 5: Add Butter and Milk

Combine the melted butter and milk in a small bowl.

Take approximately ½ cup of the cake batter and mix it into the butter mixture.

This helps lighten the butter mixture.

Carefully fold the butter mixture back into the main batter.

Mix gently until fully incorporated.

The batter should remain airy and smooth.

Step 6: Bake the Sponge Cake

Pour the batter into the prepared pan.

Spread evenly with an offset spatula.

Tap the pan gently on the counter once or twice to remove large air bubbles.

Bake for 10–14 minutes.

The cake is done when:

• The surface is lightly golden
• It springs back when touched
• A toothpick inserted comes out clean

Avoid overbaking because dry cake can crack during rolling.

Step 7: Roll the Cake While Warm

Place a clean kitchen towel on the counter.

Dust it generously with powdered sugar.

Immediately invert the hot cake onto the towel.

Carefully peel away the parchment paper.

Starting from the short side, roll the cake together with the towel.

Allow it to cool completely in the rolled shape.

This technique helps train the cake to hold its spiral shape later.

Step 8: Prepare the Blueberry Filling

Place the blueberries into a saucepan.

Add:

• Sugar
• Lemon juice
• Lemon zest
• Water

Cook over medium heat.

Stir frequently.

After approximately 5–7 minutes the berries will begin releasing juice.

Mash some berries gently with a spoon.

Mix cornstarch with cold water until smooth.

Pour the slurry into the blueberry mixture.

Continue cooking for 2–3 minutes.

The filling should become thick and glossy.

Remove from heat.

Allow it to cool completely.

The finished filling should be spreadable but not runny.

Step 9: Prepare the Whipped Cream

Pour chilled heavy cream into a cold mixing bowl.

Add powdered sugar.

Add vanilla extract.

Beat on medium-high speed.

Continue until medium-firm peaks form.

Do not overwhip because the cream may become grainy.

Reserve several tablespoons for decoration if desired.

Step 10: Create Blueberry Cream Variation

For a stronger blueberry flavor, mix:

• 3 tablespoons blueberry puree
• 1 tablespoon powdered sugar

into part of the whipped cream.

Fold gently until evenly colored.

This creates beautiful purple streaks throughout the filling.

Step 11: Unroll the Cake

Once the cake is completely cool, carefully unroll it.

Small cracks are normal.

If major cracks appear, the cake may have been slightly overbaked.

Spread a thin layer of blueberry filling across the surface.

Leave approximately 1.5 centimeters uncovered around the edges.

Spread the whipped cream over the blueberry layer.

Keep the cream layer even for a uniform spiral.

Scatter a few fresh blueberries across the cream if desired.

Step 12: Roll the Swiss Roll

Starting from the same end used earlier, roll the cake tightly but gently.

Use steady pressure.

Avoid squeezing too hard.

Place the finished roll seam-side down.

Wrap tightly in plastic wrap.

Refrigerate for at least 2 hours.

Chilling helps the roll set properly and makes slicing easier.

Step 13: Decoration

Remove the chilled Swiss roll from the refrigerator.

Trim both ends using a sharp knife for a clean appearance.

Transfer to a serving platter.

Decorate with:

• Fresh blueberries
• Whipped cream swirls
• White chocolate shavings
• Powdered sugar

For a bakery-style finish, pipe rosettes of whipped cream along the top and place blueberries on each rosette.

Professional Tips for the Best Blueberry Swiss Roll

Use room-temperature eggs because they whip more effectively and create greater volume.

Always sift the flour to avoid lumps and preserve air in the batter.

Roll the cake while it is still warm to prevent cracking.

Cool the blueberry filling completely before spreading.

Use chilled cream and chilled equipment when whipping cream.

Avoid overfilling the roll because excess filling can squeeze out during rolling.

Allow the finished roll to chill thoroughly before slicing.

Clean the knife between cuts for neat slices.

Storage Instructions

Refrigerator:

Store covered for up to 3 days.

Freezer:

Wrap tightly in plastic wrap and then aluminum foil.

Freeze for up to 1 month.

Thaw overnight in the refrigerator before serving.

Flavor Variations

Lemon Blueberry Swiss Roll

Increase lemon zest to 2 tablespoons and add lemon curd beneath the cream layer.

Blueberry Cheesecake Swiss Roll

Mix 150 grams softened cream cheese into the whipped cream.

White Chocolate Blueberry Swiss Roll

Add melted white chocolate to the cream filling for extra richness.

Mixed Berry Swiss Roll

Replace half of the blueberries with raspberries, strawberries, or blackberries.

Serving Suggestions

Serve chilled with:

• Hot tea
• Coffee
• Vanilla ice cream
• Fresh berry compote
• Lemon sauce
• Sweetened whipped cream

The finished blueberry Swiss roll should have a soft, flexible sponge with visible spirals of blueberry filling and cream, delivering a balance of sweetness, freshness, and rich berry flavor in every slice.
