Place vanilla and chopped chocolate into a large mixing bowl

Mix sugar, evaporated milk and 1 tablespoon of butter in a medium sized saucepan. Melt together and bring to a rolling boil. Stir continuously.

Add the remaining butter and the marshmallow creme and return to the boil - still mixing.

Once boiling, immediately pour into choc chip mix and beat until smooth and melted.

Pour the fudge into an 8 x 8inch tin, well buttered.

Cool at room temperature and cut into squares

Can use regular chocolate chips if preferred
