To make the spider cookies, lay 10 of the cooled cookies out in front of you. Spoon the melted chocolate into a piping bag and the royal icing into another, then snip off the ends using scissors. Pipe a dot of royal icing onto the back of two Maltesers, and arrange these onto one of the cookies to create the head and body of the spider. Repeat with the remaining nine cookies and the rest of the Maltesers. Pipe eight spider legs around the bodies of the spiders using the chocolate. Pipe two small dots of royal icing onto the heads to create eyes, then pipe very small dots of chocolate over the eyes to create pupils. If you like, decorate the bodies with the royal icing.

Heat the oven to 190C/170C fan/gas 5 and line a shallow 23cm square baking tin with baking parchment. Tip the beans, cocoa, coffee granules, xylitol, vanilla, eggs and yogurt into a large bowl. Blitz using a hand blender until smooth. Or, do this in a food processor. Add the baking powder, then blitz again.
