This low-carb berry Swiss roll put me through my paces. It’s actually really tricky to create a keto cake that is flexible enough to roll without breaking.
The secret is the psyllium husk powder. This is why it is super important to use the powder instead of the whole husks. If you only have the husks, put them in your spice grinder or bullet blender and blitz them to powder.
The freeze-dried raspberries have a wonderful tang that is the perfect foil for the sweet mascarpone filling. Don’t worry if you can’t find any, just use one of the berry chia jam recipes here on the blog instead. You could also use fresh whole raspberries (not frozen as they would release excess juices).
Also, make sure that you use ground psyllium husks (psyllium husk powder) and not the whole psyllium husks. Although there are ready-made products you can buy, they are often too dense to use in low-carb baking. It's best if you make psyllium husk powder at home simply by powdering the whole husks in a food processor or a coffee grinder. Trust me, it makes a huge difference!
Patience and persistence is the key for this cake. And if it cracks? Just cover it with whipped cream, ha ha. Enjoy!

Instructions
- Pre-heat oven to 170 °C/ 340 °F (fan assisted), or 190 °C/ 375 °F (conventional) fan forced.
- Beat the eggs and Swerve with a stand mixer until doubled in volume (approx. 5 minutes).
- Gently fold in the dry ingredients.
- Pour into a greased and lined lamington tin (25x38 cm/ 10x15 inches). Bake for 12-15 minutes. Keep checking from about 10 minutes onwards. You want the centre to be just set, but not wet. Do not overcook the sponge or it will break when you roll it.
- Remove from the oven and let stand for 3 minutes.
- Turn out onto baking paper and very gently roll up along the long side.
- Wrap the roll in a clean tea towel and leave to cool down for 2-3 minutes while you prepare the filling.
- Prepare the filling by whipping the cream, mascarpone and powdered Swerve together until thick. Fold the crumbled raspberries through (or use any berry chia jam recipe here on the blog or fresh berries instead).
- Once the sponge has cooled down, gently unroll it. Spread the mascarpone and raspberry filling inside. Do not go too close on the edges or the filling will ooze out as you roll it.
- Roll the cake by pulling the paper towards you and use your other hand to shape the sponge into a roll.
- Place in the fridge for half an hour. Optionally, dust with powdered Erythritol or Swerve and top with more crushed raspberries.
Tip: For equal serving sizes, cut the roll in half and then cut each of the two pieces in half. You'll end up with four equal pieces, each of which you can then cut into three parts to get a total of 12 slices.
- Keep refrigerated for up to 5 days.
Tip: Convert this berry Swiss roll into a delicious frozen dessert! Simply slice into desired servings and freeze for 2 hours.
