Ah, you’re talking about a Swiss Chocolate Cake, sometimes called a Swiss Chocolate Roll or Swiss Roll Cake—a light, fluffy cake rolled with chocolate filling. 🍫 Let me give you the full guide:
1. What Is Swiss Chocolate Cake?
- A sponge-based cake that’s light and airy.
- Often rolled into a Swiss roll with chocolate ganache, buttercream, or whipped cream filling.
- Called “Swiss” because of the soft sponge technique, not because it originated in Switzerland.
2. Ingredients
For the Sponge Cake
- 4 large eggs, room temperature
- ¾ cup (150 g) granulated sugar
- ½ cup (60 g) all-purpose flour
- ¼ cup (25 g) unsweetened cocoa powder
- 1 tsp vanilla extract
- ¼ tsp salt
For the Filling
- ½ cup (120 ml) heavy cream
- 4 oz (115 g) semi-sweet chocolate, chopped
- 1 tbsp butter (optional, for shine)
Optional Topping
- Powdered sugar or cocoa powder for dusting
- Chocolate shavings
3. Step-by-Step Instructions
Step 1: Prepare the Pan
- Line a jelly roll pan (10×15 inches) with parchment paper.
- Lightly grease the parchment.
Step 2: Make the Sponge Cake
- Preheat oven to 350°F (175°C).
- Beat eggs and sugar in a bowl until thick, pale, and fluffy (about 5–7 minutes).
- Sift together flour, cocoa powder, and salt.
- Gently fold the dry ingredients into the egg mixture in batches, being careful not to deflate the batter.
- Add vanilla extract and fold lightly.
- Pour batter evenly into the prepared pan and smooth the top.
Step 3: Bake
- Bake for 12–15 minutes until the cake springs back lightly to touch.
- Do not overbake, or the sponge will crack when rolling.
Step 4: Roll the Cake
- While warm, turn the cake onto a clean kitchen towel dusted with powdered sugar.
- Peel off the parchment paper.
- Roll the cake gently with the towel (jelly-roll style) and let it cool completely.
Step 5: Prepare the Filling
- Heat heavy cream until just boiling.
- Pour over chopped chocolate; let sit 1–2 minutes.
- Stir until smooth; add butter if using.
- Let the ganache or chocolate cream cool slightly.
Step 6: Assemble
- Unroll the cooled cake carefully.
- Spread the chocolate filling evenly.
- Roll the cake back up without the towel.
- Chill for at least 30 minutes to set.
Step 7: Serve
- Slice gently with a serrated knife.
- Dust with powdered sugar, cocoa, or decorate with chocolate shavings.
4. Tips for Perfect Swiss Chocolate Cake
- Eggs at room temperature → fluffier sponge.
- Fold gently → don’t deflate the batter.
- Roll while warm → prevents cracking.
- Chill before slicing → cleaner slices.
- Variations:
- Use whipped cream and berries for a lighter filling.
- Sprinkle espresso powder in cocoa for a mocha twist.
Swiss Chocolate Cake is a light, elegant dessert—perfect for parties, birthdays, or a fancy treat.
I can also make a shortcut microwave or air fryer version that’s fast but still fluffy and chocolatey if you want.
Do you want me to make that version?
