Tips & Variations

• Use marshmallow fluff instead of mini marshmallows for smooth, creamy swirls that remain distinct.
• Don’t overmix the marshmallow swirl; drag the knife gently for thick, visible ribbons.
• For a s’mores twist, sprinkle crushed graham crackers on top before chilling.
• Toasting the marshmallow top lightly with a kitchen torch adds a caramelized flavor.
• Dairy-free option: substitute dairy-free chocolate and coconut condensed milk.
• Extra chocolatey: stir in ½ cup chopped dark chocolate before swirling.
• Add crunch by mixing in crushed cookies or chopped nuts.
• For a graham cracker crust, press crushed graham crackers into the bottom of the pan before pouring in the fudge.

Storage

Store leftover fudge in an airtight container in the refrigerator for up to 1 week. To enjoy, bring the fudge to room temperature for 10–15 minutes before serving. Avoid leaving it out at room temperature for extended periods to maintain texture and freshness.

FAQs

Can I use mini marshmallows instead of marshmallow fluff?

Mini marshmallows tend to melt completely into the fudge, losing the distinct swirl effect. Marshmallow fluff is best for creating smooth, visible ribbons in the fudge.

How do I get clean cuts when slicing fudge?

Chill the fudge thoroughly until firm, then use a sharp knife warmed slightly under hot water and dried before cutting. This helps create clean, smooth edges without crumbling.
