  • Thermometer
  • Bain-marie (optional)
  • Silicone mould or ice cube tray
  • Heat proof bowl


  • 1 large bar of high quality dark chocolate for the base (can opt for milk or white base if preferred)
  • 1 small bar dairy-free white chocolate, for topping (optional)
  • 2 tbsp pistaccios or other nuts of choice (optional)
  • 2 tbsp dried fruit of choice, e.g. raisins/cherries (optional)


  • Set up the bain-marie by adding about 1-2cm of boiling water to a small saucepan, and placing a small glass bowl on top. The bottom of the glass bowl should not touch the water underneath.
  • Partially fill a sink or empty washing up bowl with cold water, ready to place the bowl of melted chocolate in to cool down
  • Break ¾ of the dark chocolate bar into chunks and place into the glass bowl over the bain-marie. On a medium-low heat, wait until the chocolate is fully melted while stirring occasionally. Then continue to heat until the chocolate has reached exactly 46°C or 114.8°F. Remove the bowl from pan immediately and place into the prepared sink of cool water. Add the remaining ¼ of unmelted chocolate into the bowl and stir until the thermometer is reading 26°C or 78.8°F.
  • As soon as this temperature has been reached, place the bowl back into the bain-marie on a medium heat, and wait until the chocolate has heated up to 32°C or 89.6°F, then immediately remove from the saucepan. Do not let the chocolate get hotter than this - if it does, you will need to repeat the previous steps by cooling back down and reheating again.
  • Pour the tempered chocolate into the silicone mould and spread it out to each corner using the end of a flat knife or spoon. Gently tap the mould to evenly disperse the chocolate.
  • Quickly prepare the white chocolate, if using as a topping. I don't bother tempering it as you won't be using very much of it. Simply break up into chunks and microwave in a heat proof plastic or ceramic bowl until melted, then use a small spoon to drizzle it over the dark chocolate base. If you like, you can get fancy using a cocktail stick to drag vertical lines through the chocolate to create extra nice patterns.
  • Finish by sprinkling over your other toppings. You can opt for chopped nuts, dried fruit, or other fun toppings like toffee chunks.
  • Leave the chocolate bars at room temperature to cool for about 45 minutes, then transfer to the fridge and continue to cool until fully set (approx 2 hours in total). Once ready, enjoy immediately or wrap up each individual bar in cellophane as a gift.
