Recipe Q&A Section

Can I use different types of chocolate?

Yes, semi-sweet chocolate chips work best for balanced sweetness, but you can substitute with milk or dark chocolate depending on preference.

What is the best way to melt the chocolate and marshmallows?

Microwave the chocolate chips, condensed milk, and butter in short intervals, stirring often to avoid burning. Add marshmallows afterward and stir until mostly melted.

How should the fudge be stored?

Store the set fudge in an airtight container at room temperature for up to a week or refrigerate for up to two weeks.

Can nuts be added to this chocolate treat?

Yes, folding in chopped toasted walnuts or pecans before setting adds a crunchy, nutty dimension.

Is it necessary to refrigerate the fudge before cutting?

While you can chill it in the fridge for faster setting, allowing it to set at room temperature for a couple of hours also works well.
