Ingredients Needed Before Making the Soft Blueberry Swiss Roll Cake

1. Medium-Protein All-Purpose Flour - Choose medium-protein flour or plain flour to help the batter rise properly, producing a sponge cake that is light, soft, and flexible enough to roll without cracking.

2. Large Eggs - Use room-temperature eggs so they whip up more easily and create a thick, stable batter. Eggs are essential for giving the sponge cake a strong yet tender structure.

3. Fine Granulated Sugar - Helps sweeten the batter, supports the rising process, and keeps the cake moist so it remains soft even after cooling.

4. Blueberry Powder or Natural Purple Food Coloring - Provides a beautiful purple color and the distinctive aroma of blueberries. You can use dried blueberry powder or blueberry extract for a more authentic and natural flavor.

5. Melted Unsalted Butter - Adds a delicate buttery flavor, a pleasant aroma, and creates a sponge cake that is moist and melts in your mouth.

6. Heavy Cream and Powdered Sugar - Used as the main filling. Whipped cream provides a balanced sweet and creamy flavor while creating a smooth texture that holds the cake roll together.

7. Fresh Blueberries - Used for decoration and additional filling. They provide a refreshing sweet-tart flavor, natural color, and an appealing fruity aroma.

8. Vanilla Extract and a Pinch of Salt - Vanilla enhances the overall flavor, while a small amount of salt intensifies the sweetness and fruitiness, creating a richer and more balanced taste.

How to Make a Soft Blueberry Swiss Roll Cake

A. Making the Sponge Cake Batter

• Preheat the oven to 170°C (340°F). Line a 25 × 30 cm baking tray with parchment paper to prevent sticking and make removal easier.
• Beat the eggs and granulated sugar on high speed for 6–7 minutes until the mixture becomes pale, thick, and leaves ribbons when the whisk is lifted.
• Sift the all-purpose flour and cornstarch together, then gradually fold them into the batter using gentle folding motions to avoid deflating the mixture.
• Add the melted butter, vanilla extract, blueberry powder or purple food coloring, and a pinch of salt. Mix gently until the color is evenly distributed and no residue remains at the bottom of the bowl.
• Pour the batter into the prepared tray and spread it evenly. Bake for 12–15 minutes, or until the surface springs back lightly when touched.
• Remove the sponge cake from the oven, invert it onto a fresh sheet of parchment paper, carefully peel away the original paper, and allow it to cool completely.

B. Preparing the Cream Filling

In a chilled bowl, whip the heavy cream with powdered sugar and a small amount of blueberry extract until soft, firm peaks form. Avoid overwhipping, as the cream may separate.

C. Rolling and Decorating

• Spread the whipped cream evenly over the cooled sponge cake, reserving a small amount for decorating the outside.
• Roll the sponge cake tightly and carefully from one side, using the parchment paper to help create a neat and even shape.
• Wrap the cake roll in plastic wrap and refrigerate for 30–40 minutes to help it set and maintain its shape.
• Once chilled, remove the cake from the refrigerator and spread the remaining cream evenly over the outer surface.
• Decorate the top and sides with fresh blueberries, decorative leaves, and a light dusting of powdered sugar if desired.

Storage and Serving Guide Soft Blueberry Swiss Roll Cake

1. Best Time to Enjoy: Serve chilled directly from the refrigerator to keep the roll firm, prevent the cream from melting, and enjoy the freshest fruit flavor.
2. Freshness: Store in an airtight container in the refrigerator. The cake will remain soft and delicious for up to 2–3 days.
3. Important: Do not leave the cake at room temperature for more than 1.5 hours, as the cream may soften and the roll may lose its shape.
4. Freezing Not Recommended: Freezing may damage the sponge cake’s texture and cause the cream to become watery after thawing, resulting in a less enjoyable flavor and texture.
