Making the Fudge

• In a medium saucepan, mix together the granulated sugar, unsweetened cocoa powder, milk, and unsalted butter until smooth.
• Place the saucepan over medium heat, stirring consistently until the mixture begins to boil.
• Allow the mixture to boil undisturbed for about 5 minutes.
• Remove from heat and stir in the vanilla extract and chocolate chips until melted and well combined.
• If using, gently fold in the chopped nuts evenly throughout the fudge.
• Pour the fudge mixture into a greased 8x8 inch pan and add toppings if desired.
• Allow to cool at room temperature for about 2 hours until set, then cut into squares.
