Ingredients

Cake:
  • 8 oz Rich Tea biscuits or similar cookies/biscuits
  • ⅔ c unsalted butter (5 oz) 1 ¼ sticks, softened
  • ⅛ tsp salt a pinch
  • ¾ cup Baker's/caster sugar (if the sugar isn't fine, it might be gritty)
  • 5 oz dark chocolate
Coating:
  • 8 oz dark chocolate good quality
  • Chocolate curls bits of a chocolate bar, or whatever you would like to put on top the cake

Instructions

    Cup of Yum
  1. Butter a 6" cake tin and line the bottom with parchment or waxed paper.
  2. Break the tea biscuits into small pieces (about 1" long) and put into a bowl and set aside.
  3. Beat the butter, salt, and sugar together until light and fluffy.
  4. Melt the dark chocolate using the defrost function of the microwave or over a double boiler. Stop heating the chocolate when it is almost melted. Add the melted chocolate to the butter and sugar mixture and mix well until combined.
  5. Gently add in the Rich Tea biscuit pieces until they are fully coated in chocolate mixture.
  6. Put this into the prepared cake tin, carefully trying to fill all the air spots so there aren't holes in the bottom or middle of the cake (the bottom will be the top).
  7. Place the tin in the fridge for about 4 hours. When ready to finish the cake, remove from the fridge and allow to stand for about 30 minutes.
  8. Run a knife around the edge and turn upside down onto a cooling rack placed on a sheet tray (or anything to catch chocolate drips). Remove the parchment paper.
  9. Now, melt the dark chocolate for the coating in a double boiler or again in the microwave on defrost to slowly melt the chocolate, stirring at intervals. Stop heating the chocolate when there are still pieces of chocolate. Continue stirring off the heat until completely smooth.
  10. Slowly pour the melted chocolate over the top and sides of the cake and smooth using a butter or palette knife.
  11. Allow to set at room temperature. When set, remove the cake and place on a serving plate and decorate as desired.

Notes

  • Use good quality chocolate for best results (DO NOT USE HERSHEY'S)
