Fudge Base
- 3 cups semi-sweet chocolate chips
- 1 (14 oz) can sweetened condensed milk
- 2 tbsp unsalted butter
- 1/8 tsp salt
- 1 tsp vanilla extract
Swirl
- 1 1/4 cups mini marshmallows
- Prep Your Pan: Line an 8×8-inch square baking pan with parchment paper, leaving a little overhang on the sides to easily lift out the fudge later.
- 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, taking care not to overheat the chocolate.
- Add Vanilla: Remove the pan from heat and stir in 1 tsp vanilla extract until fully combined, enhancing the depth of flavor.
- Fold in Marshmallows: Quickly add 1 1/4 cups mini marshmallows and gently fold them in with a spatula, just enough to create swirls without melting the marshmallows completely.
- Transfer to Pan and Swirl: Pour the fudge mixture into the prepared pan. Use your spatula to gently swirl the top so some marshmallows peek through for a beautiful marbled effect.
- Chill and Set: Let the pan cool at room temperature for about 10 minutes, then transfer it 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 using the parchment paper overhang and slice into 16 squares with a buttered knife for clean cuts. Enjoy!
Notes
- Do not overheat chocolate or it may seize; always melt on low heat and stir constantly.
- Add marshmallows last to maintain swirled texture without fully melting them.
- Line the pan with parchment paper for easy removal and neat cutting.
- Use a buttered knife to cut fudge cleanly without sticking.
- Store fudge in an airtight container in the fridge for up to 7 days or freeze for up to 3 months.
- For a dairy-free option, substitute with vegan condensed milk and chocolate chips.
