Step‑by‑Step Instructions for Marshmallow Swirl Fudge
Step 1: Melt Ingredients
In a medium saucepan, combine 1 cup of semi-sweet chocolate chips, 1 can of sweetened condensed milk, and 2 tablespoons of unsalted butter over low heat. Stir continuously for about 5-7 minutes until the mixture becomes smooth and glossy, ensuring there are no lumps of chocolate. This creamy base is the heart of your Marshmallow Swirl Fudge.
Step 2: Add Flavoring
Once the chocolate mixture is smoothly melted, remove the saucepan from heat and stir in 1 teaspoon of vanilla extract and a pinch of salt. Continue to mix until these flavors are fully incorporated, providing depth to the fudge. This step enhances the richness and sweetness, making your fudge irresistible.
Step 3: Prepare Pan
Line an 8×8-inch baking dish with parchment paper, allowing some overhang for easy removal later. Carefully pour the chocolate mixture into the prepared pan, using a spatula to spread it evenly. Tap the pan gently on the counter to eliminate any air bubbles, ensuring a smooth and even texture for your Marshmallow Swirl Fudge.
Step 4: Add Swirls
Dollop generous spoonfuls of marshmallow fluff on top of the fudge mixture, spacing them evenly. Using a butter knife or the tip of a spatula, gently swirl the marshmallow through the chocolate. Aim for a marbled effect without overmixing, as you want to maintain distinct ribbons of marshmallow in the fudge for that perfect gooeyness.
Step 5: Chill
Place the pan in the refrigerator and allow the fudge to chill for at least 2 hours, or until it is firm to the touch. This chilling process is crucial for setting the fudge and achieving the right, dense texture that characterizes your delectable Marshmallow Swirl Fudge.
Step 6: Serve
Once set, remove the fudge from the pan using the parchment paper overhang. Place it on a cutting board and cut into squares with a sharp knife for clean edges. Serve immediately or store in an airtight container in the refrigerator, ready to share your delicious Marshmallow Swirl Fudge with friends and family!
