Anyone who has failed to make a molten chocolate pudding with a lava-like interior should take solace in this fool-proof variation. Just like the original, this recipe relies on good quality dark chocolate and only the smallest amount of flour to get that irresistible oozing interior and slightly cakey surround. If you choose to make this as a dessert for friends and family, it’s worth noting that you can prepare the batter in advance to bake in the oven just before you’re ready to serve.
