Ingredients

Scale

Main Ingredients

3 cups semi-sweet chocolate chips
1 (14 oz) can sweetened condensed milk
2 tbsp unsalted butter
1 tsp vanilla extract
1/8 tsp salt
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 for easy lifting later.
Melt Chocolate, Milk, Butter, and Salt: In a medium saucepan over low heat, combine the chocolate chips, sweetened condensed milk, butter, and salt. Stir constantly until the mixture is fully melted and smooth to avoid scorching or seizing the chocolate.
Add Vanilla: Remove the pan from heat and stir in the vanilla extract thoroughly for flavor.
Fold in Marshmallows: Quickly add the mini marshmallows and gently fold them in with a spatula just enough to create swirls without melting them completely, preserving their texture.
Transfer to Pan and Swirl: Pour the mixture into the prepared pan and use the spatula to gently swirl the top so some marshmallows peek through.
Chill and Set: Let the fudge cool at room temperature for 10 minutes, then transfer to the refrigerator for at least 2 hours until fully set.
Slice and Serve: Once set, lift the fudge out using the parchment paper overhang and slice into 16 squares using a buttered knife for clean edges.

Notes

Don’t overheat the chocolate; stir constantly on low heat to prevent seizing.
Add marshmallows last to maintain the swirl effect and prevent complete melting.
Use parchment paper in the pan for easy removal and clean cutting.
A buttered knife helps achieve cleaner cuts.
Store fudge in an airtight container to prevent drying out.
You can substitute semi-sweet chocolate chips with dark or milk chocolate.
For a dairy-free version, use vegan condensed milk and chocolate.
Add crushed peppermint or chopped nuts for texture variations.
Make the fudge up to 5 days ahead and keep refrigerated, or freeze up to 3 months with parchment between layers.
