My mom has been making her own hot fudge sauce ever since I can remember. The funny thing is that she doesn't really like ice cream. Go figure. Well, after many different recipes and methods - this might be her best and easiest yet.
1 can sweetened condensed milk
1 cup mini marshmallows
1/2 cup milk
1 package chocolate chips
Just dump everything in a saucepan on medium heat and stir until it's all melted into smooth deliciousness. Top on your favorite frozen treat.
