Cake Decorating Tutorial: Decadent Black Forest Swiss Roll

by

Fluffy chocolate sponge, whipped cream, cherries, and a silky ganache finish

Overview

The Black Forest Swiss Roll is an elegant twist on the classic German Black Forest Cake (Schwarzwälder Kirschtorte), known for its rich layers of chocolate sponge, whipped cream, cherries, and chocolate shavings. Instead of a tall layer cake, this version rolls all those flavors into a spiraled masterpiece that’s easier to assemble, slice, and serve.

Equipment Needed

  • 10×15 inch (25×38 cm) jelly roll pan

  • Electric mixer or stand mixer

  • Parchment paper

  • Whisk & spatula

  • Clean kitchen towel

  • Small saucepan (for ganache & cherry filling)

  • Serrated knife (for trimming)

  • Offset spatula (for smooth decorating)

Step-by-Step Instructions

Prepare the Sponge Cake

  1. Preheat oven to 180°C (350°F). Grease a 10×15-inch jelly roll pan and line with parchment paper.

  2. In a mixing bowl, whip eggs and sugar with a hand or stand mixer on high speed for 5–6 minutes until pale and tripled in volume.

  3. Gently whisk in the vanilla extract and milk.

  4. Sift in dry ingredients: flour, cocoa powder, baking powder, and salt. Fold gently until just incorporated.

  5. Fold in melted butter last — carefully to retain air.

  6. Spread batter evenly in the prepared pan and bake for 10–12 minutes, or until sponge springs back when touched.

  7. Meanwhile, prepare a clean kitchen towel dusted generously with powdered sugar.

Roll the Cake (While Warm)

  1. Once baked, remove the cake from the oven and invert it immediately onto the prepared towel.

  2. Peel off the parchment paper carefully.

  3. Starting from the short side, roll the cake up with the towel inside (like a jelly roll). Let it cool completely rolled to prevent cracking later.

Prepare the Cherry Filling

  1. In a saucepan, add:

    • Cherries

    • Cherry syrup (or water + kirsch)

    • Sugar (to taste)

  2. Bring to a simmer. Mix cornstarch with water and add to the saucepan.

  3. Stir until thickened (about 1–2 minutes). Let it cool completely.

Whip the Cream

  • Whip cold heavy cream, powdered sugar, and vanilla until stiff peaks form.

  • Keep chilled until ready to use.

Assemble the Swiss Roll

  1. Unroll the cooled sponge gently.

  2. Spread a thin layer of whipped cream all over the surface.

  3. Spoon the cherry filling evenly across, avoiding the very edge.

  4. Carefully roll the cake back up, this time without the towel.

  5. Trim both ends with a serrated knife for clean edges.

Ganache & Final Decoration

Make Ganache:

  1. Heat heavy cream until just steaming (not boiling).

  2. Pour over chopped chocolate. Let sit 1 minute, then stir until smooth.

  3. Stir in butter for a glossy finish. Cool for 5–10 minutes until pourable but thick.

Decorate:

  1. Place the Swiss roll seam-side down on a serving platter.

  2. Pour or spread ganache over the top using an offset spatula.

  3. Sprinkle with chocolate curls or shavings.

  4. Garnish with piped whipped cream and cherries on top.
