Recipe FAQs

What chocolate works best for this fudge?

Semi-sweet chocolate chips provide a balanced sweetness and smooth melting, but milk or dark chocolate can be used to vary flavor intensity.

Can I replace the microwave method with stovetop?

Yes, gently melting the chocolate, condensed milk, and butter over low heat while stirring continuously works well to avoid burning.

How do mini marshmallows affect the texture?

They add soft, chewy pockets throughout the creamy chocolate, creating a contrast that enhances every bite.

Are nuts mandatory or optional?

Chopped walnuts or pecans are optional additions that provide a pleasant crunch and subtle nuttiness if desired.

What’s the best way to store these squares?

Keep them in an airtight container in the refrigerator for up to one week to maintain freshness and texture.
