Using a Russell Hobbs Food Processor, add the Maltesers to the processing bowl, along with the milk, malt powder, and 1tbsp of the caramel sauce. Attach the blending attachment and blitz thoroughly until no lumps remain.
Next, drizzle the remaining caramel sauce around the inside of a large glass, and sprinkle with a few pieces of sea salt.
Pour the milkshake mixture into your glass and add some whipped cream. Serve with another drizzle of caramel sauce, another small pinch of sea salt, some crushed Maltesers and chocolate shavings.
To create the whipped cream, pour the pot of double cream into a bowl and use a Russell Hobbs Hand Mixer to blend until the cream thickens and becomes whipped cream.
For an extra touch, add extra chocolate shavings.
