Ingredients
For the Chocolate Sponge Cake:
4 large eggs, at room temperature (separated)
1/2 cup (100g) granulated erythritol or preferred keto sweetener, divided
1 tsp vanilla extract
1/2 cup (50g) fine almond flour
1/4 cup (25g) coconut flour
1/4 cup (25g) unsweetened cocoa powder (Dutch-process preferred)
1 tsp baking powder
1/4 tsp salt
1/4 cup (60ml) heavy cream or unsweetened almond milk
1 tbsp melted butter or coconut oil
For the Vanilla Cream Filling:
1 cup (240ml) heavy whipping cream, cold
4 oz (115g) full-fat cream cheese, softened
1/3 cup (65g) powdered erythritol (or confectioners-style keto sweetener)
1 tsp vanilla extract
Pinch of salt
For Dusting (Optional):
2 tbsp powdered erythritol
1 tbsp unsweetened cocoa powder
Instructions
1. Prepare the Cake (Time: 25 mins)
Preheat & Prep: Preheat your oven to 350°F (175°C). Line a standard 10×15-inch jelly roll pan (or a rimmed baking sheet of similar size) with parchment paper, ensuring the paper goes up the sides. Lightly grease the paper.
Dry Whisk: In a medium bowl, whisk together the almond flour, coconut flour, cocoa powder, baking powder, and salt until well combined and no lumps remain.
Whip Egg Whites: Using a stand mixer or hand beaters, whip the 4 egg whites on medium-high speed until soft peaks form. Gradually add 1/4 cup (50g) of the erythritol, one tablespoon at a time, and continue whipping until stiff, glossy peaks form. Set aside.
Combine Yolks & Wet: In a separate large bowl, beat the egg yolks, remaining 1/4 cup erythritol, and 1 tsp vanilla until pale and thickened (about 2-3 minutes). Beat in the heavy cream (or almond milk) and melted butter.
Combine Dry & Wet: Gently fold the dry flour mixture into the egg yolk mixture until just combined. The batter will be thick.
Fold in Egg Whites: Take about 1/3 of the whipped egg whites and fold vigorously into the chocolate batter to lighten it. Then, gently but thoroughly fold in the remaining egg whites until no white streaks remain. Be careful not to deflate the mixture.
Bake: Pour and spread the batter evenly into your prepared pan using an offset spatula. Smooth the top. Bake for 12-15 minutes, or until the top is set and springs back lightly when touched.
2. Roll the Cake (Critical Step – Time: 5 mins)
Prep for Rolling: While the cake bakes, lay out a clean, lint-free kitchen towel. Dust it generously with powdered erythritol or a little extra cocoa powder.
The Immediate Roll: As soon as the cake comes out of the oven, carefully invert it onto the prepared towel. Peel off the parchment paper. Immediately, starting at one of the short ends, use the towel to gently but firmly roll the warm cake into a log, rolling the towel inside it. This “pre-roll” sets the cake’s shape and prevents cracking later.
Cool: Allow the rolled cake to cool completely on a wire rack, seam-side down. This takes about 30-45 minutes.
3. Make the Filling (Time: 10 mins)
In a large bowl, beat the cold heavy whipping cream until soft peaks form. Set aside.
In another bowl, beat the softened cream cheese, powdered sweetener, vanilla, and salt until completely smooth.
Gently fold the whipped cream into the cream cheese mixture until uniform and fluffy. Be careful not to over-mix. Chill until the cake is ready.
4. Assemble the Final Roll (Time: 10 mins)
Unroll Carefully: Once the cake log is completely cool, carefully unroll it onto the towel. It will lay flat but retain a slight curve.
Add Filling: Spread the vanilla cream filling evenly over the cake, leaving a 1-inch border at the far short end (to prevent squishing out when re-rolling).
Re-roll: Using the towel to guide you, gently re-roll the cake, this time without the towel inside. Tighten as you go.
Finish: Carefully transfer the roll, seam-side down, to your serving platter or a long piece of parchment/wax paper.
5. Serve & Store (Time: 5 mins)
Optional Decoration: Dust the top with sifted powdered erythritol and cocoa powder for a classic finish. Alternatively, drizzle with melted keto-friendly chocolate.
Chill & Slice: For cleanest slices, wrap the roll loosely in parchment and refrigerate for at least 1 hour before serving. Use a sharp, thin-bladed knife, wiping it clean between cuts.
Storage: Store covered in the refrigerator for up to 4 days. This cake does not freeze well due to the cream filling, which can become grainy upon thawing.
