In a medium saucepan, add the granulated sugar, evaporated milk, unsalted butter, and a pinch of salt. Stir them together gently, creating the perfect base for your fudge.

Place the saucepan over medium heat and bring the mixture to a rolling boil. Watch closely, stirring continuously, until it reaches that delightful bubbling stage.

Keep stirring constantly for exactly 5 minutes. This is where the magic happens! The mixture should thicken and take on a beautiful golden color as it cooks.

Remove the saucepan from heat and quickly stir in the semi-sweet chocolate chips and mini marshmallows. The chocolate will melt, creating a creamy blend, while the marshmallows add a fun twist.

Stir the mixture until smooth, ensuring everything is fully combined. Finally, gently mix in the vanilla extract for that extra depth of flavor.

Carefully pour the fudge mixture into a prepared pan, spreading it evenly. Allow it to cool at room temperature until it sets, then cut into squares.
