  • 1 cup mascarpone cheese
  • ½ cup cream heavy/whipping
  • 2 tablespoons allulose or other low carb sweeteber

To Decorate

  • ½ cup cocoa unsweetened


Sponge Fingers

  • Pre-heat oven to 180C/350F degrees
  • Linea 8-inch square baking tin with parchment paper.
  • Whisk the butter with the erythritol until creamy
  • Add the egg yolks and vanilla and continue to whisk.
  • Add the coconut flour, salt and baking powder and mix well.
  • Add the water if the mixture is too stiff.
  • In a separate bowl whisk the egg whites to stiff peaks.
  • Gently fold in the egg whites and mix until combined
  • Spoon into the tin, evenly smooth out the cake mixture.
  • Bake for 25 minutes until the sponge is golden and firm.
  • Remove from the oven and cool.

Make the Cream Layer

  • In a medium bowl beat the mascarpone and cream together until you have a firm mixture.
  • Add the allulose and vanilla. Continue to beat until smooth.

To Assemble

  • Cut the sponge into fingers
  • In a shallow bowl mix the coffee and rum.
  • Dip the sponge fingers into the coffee mixture.
  • Lay half of the fingers in the bottom of an 8 inch square baking dish. (I use a glass one)
  • Cover with half of the cream mixture.
  • Layer the other half of the sponge fingers over the cream.
  • Spoon the remaining cream over the fingers.
  • Lightly dust with cocoa.
  • Place in the fridge for at least 4 hours for the flavours to develop and the tiramisu to firm. Ideally, leave over night.
