Ingredients

Scale

Fudge Base

3 cups semi-sweet chocolate chips
1 (14 oz) can sweetened condensed milk
2 tbsp unsalted butter
1/8 tsp salt

Flavorings & Swirl

1 tsp vanilla extract
1 1/4 cups mini marshmallows

Instructions

Prep Your Pan: Line an 8×8-inch square baking pan with parchment paper, leaving a little overhang on the sides to make removal easier.
Melt Chocolate, Milk, Butter, and Salt: In a medium saucepan over low heat, combine 3 cups semi-sweet chocolate chips, 1 (14 oz) can sweetened condensed milk, 2 tbsp unsalted butter, and 1/8 tsp salt. Stir constantly until the mixture is fully melted and smooth, being careful not to overheat or scorch the chocolate.
Add Vanilla: Remove the saucepan from heat and stir in 1 tsp vanilla extract until fully combined, enhancing the fudge’s flavor.
Fold in Marshmallows: Quickly add 1 1/4 cups mini marshmallows and gently fold them into the chocolate mixture just enough to create swirls without completely melting them, preserving texture and visual appeal.
Transfer to Pan and Swirl: Pour the fudgy mixture into the prepared baking pan and use a spatula to gently swirl the top so some marshmallows peek through for a marbled effect.
Chill and Set: Allow the pan to cool at room temperature for 10 minutes, then transfer to the refrigerator for at least 2 hours, or until the fudge is fully set and firm.
Slice and Serve: Once set, lift the fudge out of the pan using the parchment overhang and slice into 16 evenly sized squares with a buttered knife to ensure clean cuts.

Notes

Do not overheat the chocolate to prevent seizing; stir constantly on low heat.
Add marshmallows last and fold gently to maintain the swirl texture.
Line your pan with parchment paper for easy removal and cleaner slicing.
A buttered knife helps achieve neater fudge pieces.
Store fudge in an airtight container to keep moisture and freshness.
Recipe can be made up to 5 days ahead and stored refrigerated or frozen up to 3 months.
For a dairy-free version, swap in vegan condensed milk and chocolate chips.
