This Original Fantasy Fudge Recipe is a no-fail fudge that is loaded with chocolate chips and walnuts for a perfectly sweet treat.
Line a 9x13-inch pan* with parchment paper.
In a large saucepan, over medium heat, mix sugar, butter, and evaporated milk.
Bring mixture to a boil, leave on heat until the mixture registers 234°F on a candy thermometer (about 5 minutes), stirring constantly.
Remove from heat and stir in chocolate chips until melted and thoroughly combined.
Beat in mini-marshmallows, walnuts, and vanilla extract.
Transfer fudge to the prepared pan and let it cool about 2 hours before cutting.
*For thicker fudge, pour the mixture into an 8x8-inch or 9x9-inch parchment paper-lined pan.
