Thermomix recipe: Viana Cake Roll. Ready in 65 minutes. Serves 8. Step-by-step Thermomix instructions on Chef Amai.

Ingredients

• 7.5 g baking powder
• 150 g caster sugar
• 180 g plain flour
• 9 large eggs, at room temperature
• 10 g cornstarch
• 75 g caster sugar
• 70 ml water
• 8 large egg yolks
• Butter or oil, for greasing
• Extra caster sugar, for dusting

Instructions

1. Preheat your oven to 185°C. Line a large rectangular baking tray (approx. 30x40 cm) with baking paper, then lightly grease and dust with a little flour.
2. Insert the butterfly whisk into the clean, dry Thermomix bowl. Add the 9 room-temperature eggs and 150 g caster sugar.
3. Whisk 8-10 min / 37°C / Speed 4, or until the mixture is very pale, thick, and has tripled in volume.
4. Remove the butterfly whisk. Add 180 g plain flour and 7.5 g baking powder to the bowl.
5. Gently fold in the flour and baking powder 10 sec / Speed 3, or until just combined. Avoid overmixing to keep the batter light.
6. Pour the batter evenly onto the prepared baking tray and spread gently.
7. Bake in the preheated oven for 20-25 minutes, or until golden brown and a skewer inserted into the center comes out clean.
8. While the cake is baking, prepare a clean kitchen towel by dusting it lightly with extra caster sugar.
9. Once baked, immediately invert the warm cake onto the sugared kitchen towel. Carefully peel off the baking paper.
10. Place 10 g cornstarch and 75 g caster sugar into the clean Thermomix bowl. Mix 5 sec / Speed 4.
11. Add 70 ml water and 8 egg yolks to the bowl. Mix 10 sec / Speed 4.
12. Cook the mixture 7-9 min / 90°C / Speed 3, or until thickened to a custard-like consistency.
13. For the last minute, cook 1 min / 90°C / Speed 2 to settle the filling and prevent sticking.
14. Transfer the filling to a clean bowl and cover with cling film directly on the surface to prevent a skin from forming. Let it cool slightly.
15. While the cake is still warm, spread the slightly cooled filling evenly over the surface of the cake.
16. Starting from one of the longer sides, carefully roll the cake tightly with the help of the kitchen towel.
17. Once rolled, let the cake cool completely, seam-side down, wrapped in the kitchen towel or cling film, to help it hold its shape.
18. Slice and serve the Viana Cake Roll.
