Set your oven to 170C/335F for standard ovens or 150C/305F for fan ovens. Grab a baking dish (5-6 cup size) and butter it lightly.

In a bowl, stir the cocoa and brown sugar, then set it aside for later.
03 -
Combine the flour, cocoa powder, salt, caster sugar, and baking powder in a bowl. Stir everything together well.
04 -
In another jug or bowl, stir the melted butter and milk. Then mix in the vanilla and egg.
05 -
Pour the egg and milk mix into the dry mixture. Stir until the batter is thick and smooth. Spread it into the buttered dish.
06 -
Sprinkle the cocoa and sugar mix evenly on top of the batter. Gently shake the dish to spread it out.
07 -
Pour the boiling water over a dessert spoon and let it spread gently over the pudding. This ensures an even top.
08 -
Pop the dish in the oven and bake for 30 minutes. The top should feel slightly springy like brownie crust when it's done.

Take it out of the oven and let it sit for just a couple of minutes. Serve while warm so the sauce is perfect.
