Vanilla and walnut fudge is irresistibly soft, creamy and sweet and can be prepared quickly and easily on the hob without the need for a sugar thermometer. It makes a perfect treat for special occasions, a tasty gift for family or friends or you could simply make it for yourself.
Place the butter, condensed milk, sugar and vanilla essence in a saucepan. Heat gently, stirring all the time, until the butter has melted and the sugar has dissolved.
Bring to the boil and then boil vigorously until the fudge is cooked (5 to 10 minutes) stirring continuously. If you have a sugar thermometer heat to a temperature of 115oC. If you don't have a sugar thermometer you can check the fudge is cooked by carrying out a soft ball test. Drop a small amount of the mixture into a bowl of cold water. If the mixture sets and forms a ball which can be squashed between your fingers then the fudge is ready.
Remove from the heat, leave to cool for a couple of minutes.
Add the broken walnuts and then beat with a spoon until the mixture has thickened and is dull in colour (about 3 to 5 minutes).
Transfer the fudge to the lined tin and press into place with the back of a spoon.
Leave the fudge to cool and then chill for about an hour to set.
Remove from the tin, discard the paper and cut into small squares or rectangles.
Store in an airtight container for up to two weeks.
