Coffee Biscuit Cream Slice



300gr Café Noir biscuits

80gr melted butter


  • Break the biscuits to fine crumb in a robot coup, then add the melted butter.

300gr white chocolate drops

125ml cream

4 tsps instant coffee granules

2 egg yolks

30gr sugar

1 leaf of gelatin soaked in cold water

2 egg whites

50gr sugar

375ml whipped cream


  • Place the chocolate in a bowl over a pot of boiled water, remove from the heat, and this helps to warm up the chocolate.
  • Meanwhile, boil 125ml cream with the instant coffee, stir to dissolve the coffee.
  • Drain the gelatin and add to the boiled cream, stir to dissolve.
  • Pour the cream over the chocolate, let it sit to allow the chocolate to melt.
  • Once the chocolate is melted, stir the mixture until smooth.
  • Separate your eggs, ensure no yolk in whites.
  • Put the egg yolks on to whisk on high speed.
  • Weigh out a smaller quantity of sugar first; put in a small pot and add just enough water to dissolve it.
  • Put it on medium heat, ensure sugar is dissolved then increase heat and cook to softball - (quite thick syrup) - you can check with a sugar thermometer if you have one. 235F.
  • Beat the yolks until they have doubled in volume.
  • Turn off the mixer, and then carefully add the boiled sugar syrup. Whisk again until thick and the mixture cools.
  • Fold the yolk mixture into the chocolate mixture.
  • Put the larger quantity of sugar on to cook as before.
  • When the syrup is nearly ready, put the egg whites on to whisk at high speed.
  • When the sugar syrup has reached softball, stop the mixer, and then carefully add the boiled sugar syrup. Continue to whisk until cooled.
  • Fold the egg white into the yolk mixture, once evenly distributed with no lumps, fold in the cream.
  • Scrape the mixture onto the prepared base level carefully, then chill until set.
