4 scoops coffee or vanilla ice cream, to serve (optional)
4 tsp coffee liqueur, to serve (optional)
Measure the milk in a large jug, then blend with the prunes and coffee in a food processor until smooth. Add the butter, sugar, egg, almonds, cocoa, flour and a pinch of salt, then blitz again to make a thick batter.
Scrape evenly and cleanly (don’t take the mixture up the sides) into 4 x 175ml ramekins (don’t use any with metal on them!). Cook in the microwave, spaced round the edge of the turntable, on Medium for 6 mins. The puddings will still look a bit moist, but that’s fine. Stand for 5 mins, then serve topped with a scoop of ice cream and a little liqueur, if you like.
