Line a square form (approx. 20 x 20 cm) with sandwich paper (also the sides). Be careful not to make any creases or folds, because otherwise the fudges will look like they are 100 years old.
Melt butter with nutmeg in a saucepan at low temperature. Add sugar and milk and bring to the boil, then cook for 4-5 minutes without stirring. If you are too curious and impatient with the species, have a second person guard the pot.

Then pull the pot off the stove. Add vanilla and peanut butter and mix with a wooden spoon.
Put the icing sugar in a heat-resistant bowl and add the peanut butter-sugar mass. Mix quickly with a wooden spoon to remove all lumps. Pour into the prepared mould and leave to cool for 10 minutes.
