First get your molds ready. Using upward strokes, heavily brush melted butter (use 50g in total) all over the inside of the pudding mold. Place the mold in the fridge or freezer. Brush more melted butter over the chilled butter, then add a good spoonful of cocoa powder into the mold. Tip the mold so the powder completely coats the butter. Tap any excess cocoa back into the jar, then repeat with the next mold.
Place a bowl over a pan of barely simmering water, then slowly melt 200g good-quality dark chocolate and 200g butter, both chopped into small pieces, together. Remove the bowl from the heat and stir until smooth. Leave to cool for about 10 mins.
In a separate bowl whisk 4 eggs and 4 egg yolks together with 200g golden caster sugar until thick and pale and the whisk leaves a trail; use an electric whisk if you want. Sift 200g plain flour into the eggs, then beat together.
Pour the melted chocolate into the egg mixture in thirds, beating well between each addition, until all the chocolate is added and the mixture is completely combined to a loose cake batter.
Tip the fondant batter into a jug, then evenly divide between the molds. The fondants can now be frozen for up to a month and cooked from frozen. Chill for at least 20 mins or up to the night before. To bake from frozen, simply carry on as stated, adding 5 mins more to the cooking time.
Heat oven to 200C/fan 180C/gas 6. Place the fondants on a baking tray, then cook for 10-12 mins until the tops have formed a crust and they are starting to come away from the sides of their molds. Remove from the oven, then leave to sit for 1 min before turning out.
Loosen the fondants by moving the tops very gently so they come away from the sides, easing them out of the molds. Tip each fondant slightly onto your hand so you know it has come away, then tip back into the mold ready to plate up.
Starting from the middle of each plate, squeeze a spiral of caramel sauce – do all the plates you need before you go on to the next stage.
Sit a fondant in the middle of each plate. Using a large spoon dipped in hot water, scoop a ‘quenelle’ of ice cream.
Carefully place the ice cream on top of the fondant, then serve immediately. Repeat with the rest of the fondants.
