Steps
- 1
Heat the oven to 180°C, or 160°C fan. Grease and line a 23 cm / 9-inch square tin.
- 2
Beat the softened salted butter, neutral oil, and light brown sugar together until creamy.
- 3
Beat in the eggs one at a time, making sure each is incorporated before adding the next.
- 4
Beat in the buttermilk and vanilla bean paste.
- 5
Fold in the self-raising flour, cocoa powder, baking powder, bicarbonate of soda, and flaked salt.
- 6
Dissolve the instant coffee in the boiling water. Gradually mix the coffee mixture into the batter until smooth.
- 7
Pour the batter into the prepared tin and bake for 30–35 minutes, until a skewer inserted into the cake comes out with a few moist crumbs.
- 8
Leave the cake to cool completely in preparation for icing.
- 9
For the icing, mix the icing sugar, cocoa powder, pinch of salt, and vanilla bean paste with enough boiling water or hot milk to make a thick, glossy icing.
- 10
Spread the icing over the cooled cake. Add the chocolate sprinkles and leave the icing to set before slicing.
- 11
For the custard, whisk around 75 ml of the cold milk with the custard powder, cocoa powder, and light brown sugar until smooth.
- 12
Heat the remaining milk until steaming, then whisk in the custard mixture.
- 13
Cook gently, whisking, until the custard has thickened.
- 14
Remove the custard from the heat and stir through the chopped milk chocolate, vanilla bean paste, and fine sea salt until glossy and smooth.
- 15
Cut the cake into school-dinner-style squares and serve with a generous amount of warm chocolate custard.
