Marshmallow Swirl Fudge Ingredients
For the Fudge Base
• Semi-sweet Chocolate Chips – The star of this fudge; use dark chocolate for a deeper flavor.
• Sweetened Condensed Milk – Adds a creamy sweetness; swap with coconut condensed milk for a dairy-free option.
• Unsalted Butter – Creates a rich texture and helps melt the chocolate smoothly.
• Vanilla Extract – Infuses a lovely hint of flavor to elevate the chocolate.
• Salt – Balances the sweetness and enhances all the flavors.
For the Swirls
• Marshmallow Fluff – Essential for those beautiful swirls; mini marshmallows can be used, but fluff gives a smoother texture.
Step‑by‑Step Instructions for Marshmallow Swirl Fudge
Step 1: Melt Ingredients
In a medium saucepan over low heat, combine semi-sweet chocolate chips, sweetened condensed milk, and unsalted butter. Stir constantly for about 5–7 minutes, until the mixture is completely smooth and glossy. Be patient and ensure the chocolate doesn’t burn by maintaining a gentle heat. You’ll know it’s ready when the chocolate is fully melted and seamlessly blended with the other ingredients.
Step 2: Add Flavorings
Once the fudge base is smooth, remove the saucepan from heat. Stir in a teaspoon of vanilla extract and a pinch of salt to enhance the flavors. Mix well for about 30 seconds until everything is well incorporated. This step is essential to add depth to your creamy Marshmallow Swirl Fudge. Let the mixture cool slightly before transferring it to the baking dish.
Step 3: Line Baking Dish
Prepare an 8×8-inch baking dish by lining it with parchment paper, allowing some overhang on the sides for easy removal later. Make sure the parchment covers the bottom and the sides, preventing the fudge from sticking. A non-stick spray is optional but can help the parchment to adhere better. This setup will make slicing your delicious fudge a breeze once it’s set.
Step 4: Spread Mixture
Pour the luscious melted chocolate mixture into the prepared baking dish. Use a spatula to spread the fudge evenly across the bottom, ensuring there are no air pockets. The fudge should fill the dish with a smooth layer, creating a perfect base for the stunning marshmallow swirls that will follow. Aim for an even thickness to ensure uniform slicing later.
Step 5: Add Fluff
Dollop spoonfuls of marshmallow fluff over the surface of the fudge, letting it cascade across the top. With a knife or skewer, gently swirl the fluff into the chocolate mixture, creating beautiful, marbled patterns. Be careful not to overmix; you want to see distinct swirls of marshmallow for that irresistible presentation. This is where the magic happens in your Marshmallow Swirl Fudge!
Step 6: Chill
Cover the baking dish with plastic wrap and transfer it to the refrigerator. Chill for at least 2 hours, or until the fudge is firm to the touch. This cooling phase allows the flavors to meld together beautifully and ensures the fudge sets properly for that flawless texture. You’ll know it’s ready when it holds its shape well and loses any tackiness.
Step 7: Slice & Serve
Once chilled, carefully lift the fudge out of the dish using the parchment overhang. Place it on a cutting board and slice it into squares with a sharp knife. Enjoy the delightful presentation of the swirls with each piece! Share your Marshmallow Swirl Fudge with family and friends, or keep it as a special treat to enjoy throughout the week.
