For the dough

  • 3 egg whites (whipped till it forms stiff peaks)
  • 1 egg
  • 50g of oat flour
  • 30g of ground walnuts
  • 60ml of skimmed milk
  • 1 pinch of pink salt
  • Stevia or liquid saccharin

For the filling

  • 100g unsweetened dates
  • 60ml water
  • 10g California walnuts
  • 2 tablespoons cocoa powder


  1. Soak the dates in hot water.
  2. In a bowl, mix the egg, milk, and flour. Stir well and add a pinch of salt to the sweetener. You can also add a pinch of oregano and black pepper.
  3. Incorporate the whipped egg whites, mixing with encircling movements until no lumps appear.
  4. Preheat the oven to 180°C. Pour the mixture on the baking tray, lined with a non-stick base (parchment paper, a silicone sheet, etc.)
  5. In 8-10 minutes, with heat up and down, the dough will be ready.
  6. Take it out of the oven, let it cool a little, and remove it from the silicone base slowly so that it does not break.
  7. Chop the walnuts finely
  8. Crush the dates with a little water until you obtain a smooth dough. Add the cocoa powder and continue to grind so that it is well integrated. Finally, add the walnuts.
  9. Spread the mixture on top of the sponge cake sheet and roll carefully to form a roll.
  10. Wrap in plastic and let stand in the refrigerator for a few hours.
  11. Decorate with melted chocolate and walnuts and serve.
