Ingredients

Scale

For the Sponge:

  • 6 free-range eggs
  • ¾ cup caster sugar (plus extra for dusting)
  • 1 ¼ cups all-purpose flour
  • 2 tsp baking powder
  • 2 tsp instant coffee granules (mixed with a little water or rum to form a paste)
  • 3 ½ tbsp melted butter (cooled)
  • ⅔ cup ground walnuts

For the Filling:

  • 1 cup mascarpone cheese
  • ¼ cup sugar
  • ⅔ cup heavy cream (whipped)
  • ⅔ cup walnuts (roughly chopped)
  • ½ tsp vanilla extract
  • 3 drops almond essence

For Dusting:

  • Powdered sugar
  • Cocoa powder

Instructions

  1. Preheat and prepare: Preheat your oven to 400°F (200°C) or 360°F (180°C fan), and line a 10 x 15-inch baking pan with baking paper to prevent sticking.
  2. Make the sponge batter: Whisk together the eggs and caster sugar for about 5 minutes until the mixture is light and fluffy. Gently fold in the sifted flour with baking powder and a pinch of salt by hand. Then add the coffee paste, cooled melted butter, and ground walnuts, folding carefully to combine without deflating the batter.
  3. Bake the sponge: Pour the batter evenly into the prepared tin, spreading it out smoothly. Bake for 12-15 minutes until the sponge is lightly golden and springy to the touch.
  4. Roll the sponge: Remove the sponge from the oven and let it cool for a minute. Then turn it out onto a clean kitchen towel dusted with caster sugar. Roll the sponge up tightly with the towel inside, shaping it into a Swiss roll, and allow it to cool completely.
  5. Prepare the filling: In a bowl, mix the mascarpone cheese with vanilla extract, almond essence, and sugar until smooth. Gently fold in the whipped cream until fully combined and airy.
  6. Assemble the roll: Carefully unroll the cooled sponge and evenly spread the mascarpone filling over it. Sprinkle the roughly chopped walnuts on top, then roll the sponge back up without the kitchen towel.
  7. Finish and serve: Dust the roll with powdered sugar and a light sprinkle of cocoa powder for decoration. Slice and serve immediately for a delicious coffee and walnut treat.

Notes

  • Ensure the melted butter is cooled before adding to avoid cooking the eggs prematurely.
  • Use free-range eggs for best flavor and texture.
  • Rolling the sponge while warm helps prevent cracking.
  • The coffee paste can be made with rum instead of water for a slight kick.
  • Store leftovers refrigerated and consume within 2 days for optimal freshness.
