A delicious pairing of savory chocolate and sweet orange, this simple fudge is sweetened with sugar and marshmallows and flavored with orange extract and zest.
In a large, deep saucepan (I like to use a dutch oven) over medium heat, melt butter, then add sugar and evaporated milk. Cook, stirring constantly, until mixture beings to boil. Reduce heat to a simmer and allow to cook, uncovered and without stirring, for 5 minutes.
Remove saucepan from heat. Quickly add marshmallows to saucepan, then stir until marshmallows are mostly melted. Add semi-sweet chocolate chips, then stir until melted.
Add orange extract and orange zest to chocolate, then stir until incorporated.
Pour fudge into prepared baking dish and smooth out the top in an even layer. If desired, decorate top with more orange zest.
Refrigerate fudge for at least 3 hours or until set.
Lift fudge out of baking dish by gripping excess paper/foil along the sides, then transfer fudge to a work area. Peel back paper/foil from edges of fudge, then cut fudge into 1 inch squares or cut with festive cookie cutters.
