Step 1

Put 12 silicone semi sphere moulds (ours were 7cm) flat on a baking tray. Using a pastry brush, brush the chocolate over the inside of the moulds until they’re all covered – don’t worry about being too precise.

Step 2

Tip the moulds upside down and shake the excess chocolate onto some baking parchment, and scrape the top using a palette knife. Place back on the baking tray, and in the fridge for 10 mins to set completely. If your remaining melted chocolate has hardened, give it a quick burst in the microwave to melt.

Step 3

Brush the second layer of chocolate in the moulds so they’re evenly covered. Place flat on the baking tray again and leave to set in the fridge for 1 hr or overnight. Once set, carefully remove from the mould by peeling back one side and get ready to assemble by getting your hot chocolate and marshmallows.

Step 4

Place a frying pan over a high heat for 1 min until hot. Remove from the hob and place one of the chocolate spheres down on it for a second. Fill with 1 tsp of the hot chocolate powder and 1 tbsp of the marshmallows. Briefly place another one of the chocolate spheres down on the warm frying pan, and press both spheres together to form a filled ball. Repeat until you have six filled hot chocolate bombs.

Step 5

To decorate, dust them all over with edible gold lustre. Heat up a mug of milk and stir in the hot chocolate bomb to serve.
