In a large mixing bowl, whisk the cream and icing sugar until you have soft peaks. Mix in the mascarpone and pistachio paste until just combined.

Pour the coffee into a shallow dish and dip the sponge fingers in it for a couple of seconds on each side, allowing them just enough time to soak up the coffee flavour. Place in an even layer across the base of a medium-sized dish.

Carefully spread some of the pistachio-cream mix on top of the sponge layer. Top with a layer of coffee-soaked sponge fingers, before adding another layer of pistachio cream. Repeat until you have used all the sponge fingers, ensuring you end with the pistachio cream - the number of layers will depend on the size and shape of your dish.

Finish by decorating. Spoon the pistachio paste into a disposable piping bag or sandwich bag, snipping a little off the end and piping lines on top. Using a toothpick, drag through the lines in the opposite direction to create a pretty feathered pattern.

Cover and chill in the fridge for at least 6 hours, ideally overnight. Remove from the fridge 20 minutes before serving and sprinkle with chopped pistachios. Enjoy!
