Jet Puffed Marshmallow Fudge Recipe: Rich Chocolate Swirls in 15 Minutes

This recipe transforms simple ingredients into decadent fudge with minimal effort. The marshmallows create a smooth, creamy texture that blends perfectly with rich chocolate.

Ready in just 15 minutes, this treat requires no baking and sets beautifully in the fridge. The result is velvety fudge with a melt-in-your-mouth finish.

Ingredients for Jet Puffed Marshmallow Fudge

Rich chocolate, marshmallows, and a few pantry staples create this velvety treat effortlessly.

The chocolate quality matters here. Ghirardelli or Guittard semi-sweet chips melt smoothly and deliver that deep cocoa flavor. Jet-Puffed marshmallows are ideal for their consistent texture and sweetness—found in the baking aisle at any Walmart or Target. For the butter, always use unsalted so you can control the salt content. A standard can of sweetened condensed milk (like Eagle Brand) is perfect for this.

No Jet-Puffed marshmallows? Kraft marshmallows work just as well. Swap the semi-sweet chips for bittersweet if you prefer less sweetness. The heavy cream can be omitted, but it adds a luxurious texture. For a nut-free version, skip the pecans or substitute with toasted walnuts or almonds. Vanilla extract is non-negotiable—use the real stuff, not imitation.

This sets in the fridge in about 2 hours, but overnight is even better. Store in an airtight container at room temperature for up to 1 week, or freeze for 3 months. Cut into squares once fully set for easy serving.

Step-by-Step Instructions for Jet Puffed Marshmallow Fudge

This method ensures smooth, rich fudge with perfect marshmallow swirls every time.

Step 1: Prepare the Chocolate Base

Line an 8×8-inch baking pan with parchment paper, leaving an overhang on the sides for easy removal. This prevents sticking and ensures clean cuts later.

In a heavy saucepan, combine the 3 cups Semi-Sweet Chocolate Chips, 0.5 cup Unsalted Butter, and 14 oz Sweetened Condensed Milk. Melt over low heat, stirring constantly with a silicone spatula until the mixture is completely smooth and glossy.

This gentle melting process prevents scorching and ensures a velvety texture. The mixture should look like thick, pourable chocolate pudding when properly combined.

Step 2: Add Flavorings and Create Swirls

Remove the saucepan from heat and immediately stir in the 2 tsp Vanilla Extract and 0.25 tsp Sea Salt. The vanilla enhances the chocolate depth while the salt balances the sweetness.

Pour half of the chocolate mixture into your prepared pan, spreading it evenly with the spatula. Then scatter the 10 oz Jet-Puffed Marshmallows over the surface, pressing them lightly into the chocolate. These will create the signature swirls as they melt.

Carefully pour the remaining chocolate mixture over the marshmallows, using the spatula to gently swirl the marshmallows into the chocolate without fully incorporating them.

Step 3: Optional Enhancements and Setting

For extra richness, warm the 0.25 cup Heavy Cream in a small saucepan until just steaming, then drizzle it over the fudge surface. This adds a silky quality to the finished texture.

If desired, sprinkle the 0.5 cup Pecans over the top, pressing them lightly into the surface. For a decorative finish, dust with 0.5 cup Powdered Sugar or sift 2 tbsp Cocoa Powder over the top for contrast.

Allow the fudge to set at room temperature for 2 hours or refrigerate for 1 hour until firm to the touch. The marshmallows will soften and create beautiful ribbons throughout the chocolate base.

Step 4: Cut and Serve

Once fully set, use the parchment overhang to lift the fudge from the pan. Place on a cutting board and use a sharp knife dipped in hot water to make clean cuts. Wipe the knife between cuts for perfect squares.

The fudge should have a smooth, dense texture with visible swirls of melted marshmallow throughout. Each piece should hold its shape when cut but remain tender when bitten.

Store in an airtight container at room temperature for up to 5 days, or refrigerate for up to 2 weeks for extended freshness. Bring to room temperature before serving for optimal texture.

Pro Cooking Tips for Great jet puffed marshmallow fudge

Perfect Melting Technique

Use a heavy-bottomed saucepan to prevent scorching. Melt the 3 cups Semi-Sweet Chocolate Chips and 0.5 cup Unsalted Butter over low heat, stirring constantly. I use a silicone spatula for smooth blending. 🔥

Swirl Mastery

Pour half the chocolate mixture into your pan, then scatter the 10 oz Jet-Puffed Marshmallows on top. Press them lightly into the chocolate before adding the remaining mixture. Use gentle swirls to create ribbons without fully blending.

Temperature Control

Never rush the melting process. Keep the heat on low and remove from heat immediately after adding 2 tsp Vanilla Extract and 0.25 tsp Sea Salt. High heat can separate the mixture, ruining the texture.

Setting Success

For the smoothest finish, let the fudge set at room temperature for 2 hours before refrigerating. This gradual cooling prevents graininess. If using 0.25 cup Heavy Cream, warm it gently before drizzling over the top.

Clean Cutting

Use a sharp knife dipped in hot water for perfect squares. Wipe the blade between cuts to prevent sticking. The parchment overhang makes removal from the pan effortless. 💡

Storage Tips

Store in an airtight container at room temperature for up to 5 days. For longer storage, refrigerate for up to 2 weeks. Bring to room temperature before serving for the best texture.
