"Easy, Quick setting, delicious- Individual fudge pieces. They look like little fudge cookies. This can also be made in baking pans for traditional style square fudge pieces (or a combo, which is what I'm usually do.)"
In a large Pyrex (or high heat resistant) bowl put the chocolate chip pieces, baking chocolate and marshmallows.
In a large sauce pan, over medium heat, add butter and evaporated milk.
When butter has melted add sugar and salt.
Stir constantly until the mixture is boiling and has reached the temp of 220 degrees. (If you don't have a candy thermometer that's 6-7 minutes. The mixture will have boiled for a minute or two and will have gotten "fluffy". It's best to have a thermometer though).
Pour the mixture over the chocolate, and such, in the bowl. Use a large wooden spoon to stir. Stir until all the ingredients have completely melted together.
Let the remaining fudge sit for 5 minutes. When it's hardened a bit take a tablespoon side ball of fudge, round it, smash it a little, as to look like a cookie and add it to a wax or parchment paper lined cookie sheet. Add a chocolate chip to the top for garnishment.
Refrigerate all the pans of fudge for at least 2 hours.
