This is a self-saucing chocolate pudding where the batter and sauce bake together. A simple sponge mixture goes into the dish first, followed by cocoa, sugar, and hot water poured on top. During baking, the sponge rises while the liquid sinks and thickens into a glossy chocolate sauce underneath.
Self-raising flour – 110 g (¾ cup)
Cocoa powder – 3 tbsp (plus extra for the sauce layer)
Caster sugar – 110 g (½ cup)
Soft brown sugar – 90 g (⅓ cup)
Butter – 110 g (½ cup), softened
Milk – 150 ml (⅔ cup)
Egg – 1 large
Vanilla extract – 1 tsp
Hot water – 300 ml (1¼ cups)
Prepare the baking dish – Lightly grease an ovenproof dish and preheat the oven to a moderate temperature so it’s ready once the batter is mixed.
Make the sponge batter – Cream the butter and caster sugar until pale, then whisk in the egg, milk, and vanilla until smooth.
Add the dry ingredients – Gently fold in the flour and cocoa powder to create a thick but pourable batter.
Transfer to the dish – Spoon the batter into the prepared dish and level the surface gently.
Create the sauce layer – Mix cocoa powder and soft brown sugar, then sprinkle evenly over the batter.
Add hot water – Carefully pour hot water over the back of a spoon so it spreads evenly without disturbing the batter.
Bake until set – Bake until the sponge is firm on top but still soft underneath.
Rest briefly before serving – Allow the pudding to stand for a few minutes so the sauce thickens slightly.
