The hand-blender whips double cream perfectly.
1/2 pt/285 ml chilled double cream
Use a deep bowl with steep sides
Blitz, with the hand blender, in the centre of the cream, until thickish.
Then with a fork, stir in the liquid cream from round the sides, until all is thick. This takes about a minute
Why not try whipping cream, this is a lighter version of double cream, it whips beautifully without being quite so rich.
