Marshmallow Swirl Fudge Ingredients
For the Fudge Base
• Semi-Sweet Chocolate Chips – The primary ingredient providing sweetness and a deep chocolate flavor; dark chocolate can be used for a richer experience.
• Sweetened Condensed Milk – Adds creaminess and sweetness, binding the fudge; coconut condensed milk works well for a dairy-free option.
• Unsalted Butter – Enhances the fudge’s texture and richness; for a vegan option, substitute with dairy-free butter.
• Vanilla Extract – Offers depth of flavor, adding an aromatic touch; almond extract can be used for a unique twist.
• Salt – Balances the sweetness of the fudge; keeping it in is crucial for flavor depth.
For the Marshmallow Swirl
• Marshmallow Fluff (or Cream) – This is essential for that gooey texture and sweetness; for a fun twist, mini marshmallows can be used, but fluff is recommended for optimal swirls.
Step‑by‑Step Instructions for Marshmallow Swirl Fudge
Step 1: Melt Chocolate Mixture
In a medium saucepan over low heat, combine semi-sweet chocolate chips, sweetened condensed milk, and unsalted butter. Stir continuously for about 5 minutes, until the chocolate is fully melted and the mixture is smooth and glossy. This creates a rich base for your Marshmallow Swirl Fudge, so be sure not to let it burn.
Step 2: Combine Flavors
Remove the saucepan from heat, then add in the vanilla extract and a pinch of salt, mixing until well incorporated. This step enhances the overall flavor profile of the fudge, balancing the sweetness with a touch of depth. The warm fudge should still be smooth and pourable as you transition to the next step.
Step 3: Prepare Baking Dish
Line an 8×8-inch baking dish with parchment paper, allowing some overhang for easy removal. Pour the warm chocolate mixture into the prepared dish and use a spatula to spread it evenly across the bottom. Ensuring an even layer is crucial for consistent thickness in your Marshmallow Swirl Fudge.
Step 4: Swirl Marshmallow
Using a spoon, drop dollops of marshmallow fluff over the surface of the fudge layer. With a knife, gently swirl the marshmallow into the fudge without overmixing—this creates beautiful ribbons of fluff. Aim for a marbled look, keeping the marshmallow visible for an appealing presentation.
Step 5: Chill
Place the baking dish in the refrigerator and allow it to chill for at least 2 hours, or until the fudge is firm to the touch. This step is crucial for setting the fudge properly, enabling you to cut it into neat squares later. You’ll know it’s ready when it feels solid and no longer sticky.
Step 6: Cut and Serve
Once chilled, lift the fudge out of the dish using the parchment overhang. Carefully cut it into squares using a sharp knife for clean edges. Each piece of Marshmallow Swirl Fudge should have a delightful blend of chocolate and marshmallow that is ready to melt in your mouth.
