A perfect sweet and buttery treat that is best eaten with a cup of bitter coffee.
Line a 8 inch cake pan with parchment paper and grease with butter. Make sure the paper is overhanging so you can easily remove the fudge for cutting.
In a large heavy saucepan, combine the butter, sugars, half and half and salt.
Bring to a boil over medium heat.
Once the mixture is boiling good, boil for 5 minutes, stirring constantly.
Remove from heat, stir in the vanilla and mix well.
Stir in confectioner's sugar.
Spread mixture into the dish.
Cover with plastic wrap and cool until room temperature.
Cut into 1 inch squares and store in airtight container in refrigerator.
