Preparation Phase & Tools to Use (Essential Tools and Their Importance)

Before diving into making your Easy Marshmallow Swirl Fudge, gather a few basic kitchen tools to streamline the process and guarantee smooth results:

• Medium Saucepan: Crucial for melting the chocolate and combining ingredients evenly. Choose one with a heavy bottom to prevent burning.
• Rubber Spatula: Ideal for gently folding the ingredients and creating those stunning marshmallow swirls without breaking the texture.
• 8×8-inch Baking Dish: The perfect size for this batch; it helps create the ideal fudge thickness. Lining it with parchment paper ensures easy removal and clean edges.
• Mixing Bowl: Needed for pre-measuring your marshmallow crème or any mix-ins.
• Offset Spatula or Butter Knife: Handy for swirling and shaping the surface into a visually appealing pattern.
• Measuring Cups and Spoons: Precision is key to balanced flavor and texture.

Having everything prepped before you begin will make the process smoother and ensure your fudge sets perfectly without hiccups.

Preparation Tips

• Line your pan first: Use parchment paper with overhanging sides. It makes removal easier and cleanup faster.
• Use room-temperature marshmallow crème: It swirls better and blends more naturally when not cold.
• Don’t overheat the chocolate: Stir continuously once the mixture starts melting—chocolate can seize quickly if left unattended.
• Work fast when swirling: Once everything is melted and poured, act quickly to swirl before it starts to set.
• For sharper fudge squares: Chill completely (at least 2 hours) and use a warm knife to cut clean lines.

Ingredients for This Easy Marshmallow Swirl Fudge

This recipe keeps it simple with pantry staples, yet the result tastes gourmet. Here’s what you’ll need:

• 3 cups semisweet chocolate chips – Provides the rich, deep chocolate base.
• 1 (14 oz) can sweetened condensed milk – Adds creaminess and sweetness while binding everything together.
• 1 teaspoon pure vanilla extract – Enhances and balances the chocolate flavor.
• 1 cup marshmallow crème (fluff) – The star of the swirl! Creates beautiful contrast and a light, airy texture.

Optional Add-ins:

• ½ cup chopped nuts (like walnuts or pecans) – For a crunchy contrast.
• Pinch of sea salt – Adds a gourmet finish and balances sweetness.
• Crushed peppermint or sprinkles – Great for holiday versions.

Keep it classic, or get creative—the base recipe is perfectly adaptable.

Step 1: Prep Your Pan

Line an 8×8-inch square baking dish with parchment paper, letting the paper hang over the sides for easy removal later. Lightly spray or butter the parchment to prevent sticking.

---

Step 2: Melt the Chocolate Mixture

In a medium saucepan over low heat, combine the semisweet chocolate chips and the sweetened condensed milk. Stir continuously with a rubber spatula until the chocolate is fully melted and smooth. This should take about 5 minutes. Remove from heat and stir in the vanilla extract.

---

Step 3: Pour and Swirl

Quickly pour about two-thirds of the chocolate mixture into the prepared pan. Use the spatula to spread it evenly. Drop spoonfuls of marshmallow crème on top in random areas, then dollop the remaining chocolate mixture in between.

---

Step 4: Create the Swirl

Using a butter knife or an offset spatula, gently drag through the mixture in sweeping motions to create a marbled swirl pattern. Be careful not to over-mix—you want distinct swirls of white and chocolate.

---

Step 5: Chill and Set

Place the pan in the refrigerator and chill for at least 2 hours or until firm. Once set, lift the fudge out using the parchment paper and transfer it to a cutting board.

---

Step 6: Slice and Serve

Use a sharp knife (preferably warmed by running under hot water and dried) to cut the fudge into clean squares. Wipe the blade between cuts for neat edges.

---

Notes

• Room Temperature Marshmallow Crème Swirls Best: Cold marshmallow crème can be stiff and difficult to swirl. Let it sit out for 10–15 minutes before using.
• Customize the Flavors: Swap semisweet chocolate for milk or dark chocolate, or even mix them for a layered twist.
• Make It Festive: Sprinkle crushed candy canes, colored sugar, or chopped nuts on top before chilling for a seasonal flair.

---

Watch Out for These Mistakes While Cooking

• Overheating the Chocolate: High heat can scorch chocolate or cause it to seize. Always melt slowly on low heat and stir continuously.
• Skipping the Lining Step: Not lining your pan can make it very difficult to remove the fudge cleanly. Use parchment with overhang for best results.
• Overmixing the Swirl: The key to beautiful marbling is to swirl just enough to mix, not fully combine. Too much swirling leads to a muddy look.
• Not Letting It Set Fully: Rushing to cut the fudge before it firms up will result in a sticky, messy texture. Patience is essential.
• Using Old Chocolate Chips: Stale or poor-quality chocolate can affect the texture and taste. Use fresh chips for optimal results.

Frequently Asked Questions

1. Can I use milk chocolate instead of semisweet?

Yes! Milk chocolate will make the fudge sweeter and creamier. You can also do a 50/50 mix with dark or semisweet for balance.

2. Can I use mini marshmallows instead of marshmallow crème?

It’s possible, but the texture and swirl effect won’t be the same. Marshmallow crème spreads and melts more evenly for that signature look.

3. Do I need a candy thermometer for this recipe?

Nope! This recipe is entirely no-fuss—just melt, swirl, and chill. No special tools needed.

4. How long does the fudge take to set?

At least 2 hours in the fridge is recommended. For best results, let it chill overnight.

5. Can I double the recipe?

Absolutely! Use a 9×13-inch pan if doubling, and adjust the chill time slightly to account for the thicker fudge layer.

6. Can I add flavor extracts like mint or almond?

Yes! Add ¼ to ½ teaspoon of extract when mixing in the vanilla for a flavor twist. Go easy—these extracts are strong.

7. Why is my fudge grainy or crumbly?

It could be due to overheating the chocolate or using old chips. Stir constantly and use fresh ingredients for a smooth finish.

8. Is this fudge gluten-free?

Yes, the basic ingredients are naturally gluten-free, but always check labels to ensure no hidden gluten in your chocolate or marshmallow crème.
