Whizz everything apart from the crushed nuts and chocolate in a food processor until it comes together as a dough. Add the milk slowly as you don’t want a wet mix. Add the chocolate and nuts last so they hold their texture and then roll into balls and place on grease proof paper before using your thumb to squish em down. I put a little piece of chocolate and a nut on each before baking for about 8 mins at 180°. Yum!
