Step-by-Step Instructions for Marshmallow Swirl Fudge
Step 1: Prepare the Pan
Line an 8×8-inch baking pan with parchment paper, allowing some overhang for easy removal later. This small step ensures your Marshmallow Swirl Fudge comes out effortlessly. Take a moment to press the parchment firmly into the corners, which helps the fudge set evenly and prevents any sticking.
Step 2: Melt the Chocolate Mixture
In a medium saucepan, combine sweetened condensed milk and chocolate chips over low heat. Stir constantly for about 5-7 minutes until the chocolate chips fully melt and the mixture becomes smooth and silky. Keep a close eye on it to prevent burning, and watch as it transforms into a luscious chocolate goodness.
Step 3: Add Vanilla Extract
Once the chocolate is completely melted and smooth, remove the saucepan from heat and stir in the vanilla extract. This step elevates the flavor of your Marshmallow Swirl Fudge. Give it a good mix, letting the warm chocolate absorb the aroma of the vanilla, creating a tempting scent that fills your kitchen.
Step 4: Incorporate Mini Marshmallows
Quickly fold in the mini marshmallows into the warm chocolate mixture, ensuring they are evenly distributed but not fully melted. Aim for swirls of mini marshmallows visible throughout the fudge; this brings both texture and visual appeal. Stir gently for about 1-2 minutes until you see delightful pockets of marshmallow.
Step 5: Pour the Mixture
Pour the fudge mixture into the prepared baking pan, using a spatula to spread it evenly. Allow the fudge to reach the corners of the pan. Then, gently swirl the top with the spatula to reveal some of those lovely mini marshmallows, creating a beautiful marbled effect on your Marshmallow Swirl Fudge.
Step 6: Cool and Set
Let the fudge cool at room temperature for about 10 minutes, then transfer it to the fridge to set for at least 2 hours. This cooling period is crucial for the fudge to firm up properly. You’ll know it’s ready when it has a solid texture that holds together beautifully.
Step 7: Slice and Serve
Once set, lift the fudge out of the pan using the parchment overhang. Place it on a cutting board and slice into 16 squares using a buttered knife for a smooth cut. The result will be perfectly portioned pieces of your delightful Marshmallow Swirl Fudge, ready to share and indulge!

Marshmallow Swirl Fudge Recipe FAQs
