Step 1

Add the sugar, cocoa powder, and salt to a large saucepan and mix the ingredients until they are combined.

Add the milk to the saucepan and stir. Turn the heat on medium-high and continue stirring until the mixture begins to boil.

Step 3

Once the mixture begins to boil, stop stirring and add your thermometer to the side of the saucepan.

Step 4

Cook until the mixture reaches 234-degrees or forms a soft ball in cold water.

Step 5

Remove from heat and add the butter and vanilla. DON'T STIR!

Step 6

Cool to about 130-degrees and stir until some of the sheen from the fudge dulls. This may take a few minutes.

Step 7

Pour into a buttered dish.

Step 8

Run a knife gently through the fudge to get rid of some of the air bubbles and allow to set up for several hours.

Step 9

Refrigerate and enjoy!
