Bowness-on-Windermere venue, the Village Inn Bar & Grill created the cocktail using a combination of butterscotch sauce, butter, vodka, lemonade and cream.
The end result was selling more of this cocktail than any of its other cocktail offer since the movie-based drink has been launched.
Owner of the venue, Ian Dutton said: “We’re delighted with the reaction to our new butterbeer cocktail and were keen to create a really unusual taste.”
“We’re all Harry Potter fans – who isn’t?! The timing was also appropriate given the recent death of Alan Rickman – one of our favourite characters - so it’s also a nod to him.”
The venue has also just launched new ‘skinny champagne’.
Dutton is also opening a new bar/restaurant in March in Windermere called ‘The Pig’, with a menu specialising in pork dishes.
