- 2 tablespoons unsalted butter, melted
- 1 teaspoon pure vanilla extract
- ¼ teaspoon salt
- 1 cup marshmallow fluff (or marshmallow cream)

- Step 2: In a medium saucepan over low heat, melt the chocolate chips, sweetened condensed milk, and melted butter together. Stir constantly until smooth, about 3-5 minutes. Remove from heat and stir in vanilla extract and salt.
- Step 3: Pour the chocolate mixture into the prepared baking dish and spread evenly with a spatula.

Tips & Variations
- For a nutty twist, sprinkle chopped toasted nuts over the fudge before refrigerating.
- Use dark chocolate chips instead of semi-sweet for a richer flavor.
- If you prefer a firmer fudge, chill it overnight for best results.
- Swap marshmallow fluff with mini marshmallows for a different texture in the swirls.
Storage
Store the fudge in an airtight container in the refrigerator for up to 1 week. Let pieces sit at room temperature for a few minutes before serving to soften slightly. You can also freeze the fudge for up to 3 months; thaw in the refrigerator before enjoying.

FAQs
Can I use milk chocolate instead of semi-sweet chocolate?
Yes, milk chocolate can be used, but it will result in a sweeter, creamier fudge. Adjust sweetness to your taste if desired.
Do I have to use marshmallow fluff for the swirls?
Marshmallow fluff or cream works best for creating soft, gooey swirls, but mini marshmallows melted slightly can also be used if fluff isn’t available.
