Ingredients

2 cups semi-sweet chocolate chips
1 can (14 oz) sweetened condensed milk
2 tbsp unsalted butter, melted
1 tsp vanilla extract
¼ tsp salt
1 cup marshmallow fluff (or marshmallow cream)

Instructions

Step 1: In a saucepan over low heat, melt the semi-sweet chocolate chips, sweetened condensed milk, and melted butter together, stirring constantly until smooth and fully combined.
Step 2: Remove the saucepan from heat and stir in the vanilla extract and salt until they are fully incorporated.
Step 3: Line an 8×8-inch baking dish with parchment paper. Pour the melted chocolate mixture into the dish and spread evenly.
Step 4: Drop spoonfuls of marshmallow fluff over the top of the fudge, then use a knife to gently swirl the fluff into the chocolate mixture, creating a marbled effect.
Step 5: Refrigerate the dish for at least 2 hours or until the fudge is firm and set.
Step 6: Once set, lift the fudge out of the dish using the parchment paper, cut into squares, and serve.

Tips & Variations

For a festive touch, add chopped nuts or crushed peppermint candies to the fudge before swirling in the marshmallow fluff.
Use dark chocolate chips instead of semi-sweet for a richer, slightly bitter flavor contrast.
If marshmallow fluff is not available, substitute with an equal amount of mini marshmallows melted gently before swirling.

Storage

Store the fudge in an airtight container in the refrigerator for up to 1 week. For longer storage, you can freeze the fudge for up to 3 months—thaw in the refrigerator before serving. To re-soften slightly before eating, let the fudge sit at room temperature for about 10 minutes.

How to Serve

A square white baking pan lined with parchment paper holds a dessert with two swirled layers of smooth chocolate and creamy white batter, creating a marbled pattern across the surface. Scattered evenly on top are small, soft, white mini marshmallows that add a fluffy texture contrast to the glossy layers beneath. The dessert sits on a white marbled surface, enhancing the clean and bright look of the scene. photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I use milk chocolate instead of semi-sweet?

Yes, milk chocolate can be used, but the fudge will be sweeter and less intense in chocolate flavor. Adjust sweetness if desired.

Is it necessary to chill the fudge in the refrigerator?

Chilling helps the fudge set properly and makes it easier to cut. While you can let it set at room temperature, it will take much longer and may not firm up as well.

Ingredients

Scale

Fudge Base

2 cups semi-sweet chocolate chips
1 can (14 oz) sweetened condensed milk
2 tbsp unsalted butter, melted
1 tsp vanilla extract
¼ tsp salt

Marshmallow Swirl

1 cup marshmallow fluff (or marshmallow cream)

Instructions

Melt the chocolate. In a saucepan over low heat, combine the semi-sweet chocolate chips, sweetened condensed milk, and melted butter. Stir constantly until the mixture is completely smooth and melted without any lumps.
Add the vanilla and salt. Remove the saucepan from heat and stir in the vanilla extract and salt thoroughly to incorporate the flavors evenly.
Pour into the pan. Line an 8×8-inch baking dish with parchment paper. Pour the chocolate fudge mixture into the dish and spread it out evenly with a spatula.
Add the marshmallow swirl. Drop spoonfuls of marshmallow fluff on top of the chocolate layer. Using a knife, gently swirl the marshmallow into the fudge to create a marbled effect without fully mixing it in.
Chill and set. Place the baking dish in the refrigerator for at least 2 hours, or until the fudge is firm and set completely.
Cut and serve. Once set, lift the fudge from the dish using the parchment paper edges. Cut into squares and enjoy your delicious marshmallow swirl fudge!

Notes

Use parchment paper to easily lift the fudge out of the pan once set.
You can substitute semi-sweet chocolate chips with milk chocolate for a sweeter fudge or dark chocolate for a richer taste.
Be careful when melting the chocolate to avoid overheating, which can cause the chocolate to seize.
For more defined swirls, avoid over-mixing the marshmallow fluff into the fudge.
Store leftover fudge in an airtight container in the refrigerator for up to one week.
