Marshmallow Swirl Fudge Recipe
Introduction
This Marshmallow Swirl Fudge is a delightful treat combining smooth, rich chocolate with soft, gooey marshmallow swirls. Easy to make and perfect for sharing, this fudge offers a wonderful balance of flavors and textures that will satisfy any sweet tooth.

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
- Step 1: Line an 8×8-inch square baking pan with parchment paper, leaving a little overhang on the sides for easy removal.
- Step 2: 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.
- Step 3: Remove the pan from heat and stir in the vanilla extract until well combined.
- Step 4: Quickly fold in the mini marshmallows gently with a spatula, stirring just enough to create swirls without melting them completely.
- Step 5: Pour the mixture into the prepared pan. Use your spatula to swirl the marshmallows on top so they peek through.
- Step 6: Let the pan cool at room temperature for 10 minutes, then refrigerate for at least 2 hours or until fully set.
- Step 7: Lift the fudge out using the parchment overhang and slice into 16 squares with a buttered knife for clean cuts.
