Preparation Phase & Tools to Use (Essential Tools and Equipment, and Why They Matter)

Before you dive into making Easy Marshmallow Swirl Fudge, having the right tools on hand will make the process smooth, clean, and frustration-free. Here’s what you’ll need—and why each tool is essential:

• Medium saucepan: You’ll melt the chocolate and sweetened condensed milk in this. A heavy-bottomed one prevents scorching and ensures even melting.
• Rubber or silicone spatula: Ideal for scraping the sides of the pan and stirring without sticking. Plus, it helps you fold in the marshmallow for those beautiful swirls.
• 8×8 or 9×9 inch square baking pan: This determines your fudge’s thickness. Line it with parchment paper for easy removal.
• Microwave-safe bowl (optional): If you’re using the microwave instead of the stovetop, this bowl lets you melt everything safely and quickly.
• Toothpick or butter knife: Used to create those dramatic, picture-perfect swirls on top before the fudge sets.
• Parchment paper: An absolute must for lifting the fudge cleanly out of the pan.

Every one of these tools contributes to ease, speed, and a beautiful final result. Missing one might lead to frustration or a sticky cleanup—so prep your station first!

Preparation Tips

• Use quality chocolate chips or bars: The chocolate is the star here. Go for semi-sweet or dark chocolate that melts smoothly.
• Warm the marshmallow cream slightly: It swirls better when it’s a little soft. Just 10 seconds in the microwave can make a big difference.
• Don’t over-swirl: A few deliberate strokes create a bold marbled effect. Overdoing it can make the fudge look muddy.
• Chill for at least 2 hours: This gives the fudge time to firm up properly. Overnight is even better for sharp, clean cuts.
• Wipe the knife between cuts: For those perfect, bakery-style edges, wipe your knife after each slice.

Ingredients for This Easy Marshmallow Swirl Fudge

You’ll only need a handful of ingredients to make this rich and creamy Easy Marshmallow Swirl Fudge. Each one plays an important role in the texture and flavor:

• 3 cups semi-sweet chocolate chips
  For that deep, classic fudge flavor. You can substitute with dark chocolate for a more intense bite.
• 1 (14 oz) can sweetened condensed milk
  Adds creaminess and sweetness while helping the fudge set without the need for sugar syrup.
• 2 tablespoons unsalted butter
  Enhances the smooth texture and adds a rich, buttery finish.
• 1 teaspoon pure vanilla extract
  Balances the chocolate and brings out depth in flavor.
• 1 cup marshmallow crème (a.k.a. marshmallow fluff)
  Swirled into the top for a creamy, sweet contrast and beautiful visual effect.
• Optional pinch of salt
  Especially if you’re using unsalted butter, a little salt rounds out the sweetness.

Optional Add-ins:

• Chopped nuts (½ cup of walnuts or pecans) for texture.
• Peppermint extract or espresso powder for seasonal variations.

Step 1: Prep Your Pan

Line an 8×8 or 9×9 inch square baking pan with parchment paper, leaving some overhang on the sides for easy lifting. Lightly grease the paper with nonstick spray or a little butter. Set aside.

---

Step 2: Melt the Chocolate Mixture

In a medium saucepan over low heat, combine the semi-sweet chocolate chips, sweetened condensed milk, and butter. Stir constantly with a spatula until everything is fully melted and smooth. This should take about 5–7 minutes. Remove from heat and stir in the vanilla extract (and a pinch of salt, if using).

---

Step 3: Pour and Swirl

Pour the chocolate mixture into the prepared pan and spread it evenly. Immediately spoon dollops of marshmallow crème over the top—try to space them out. Use a toothpick, skewer, or butter knife to gently swirl the marshmallow into the chocolate. Aim for big, bold swirls without overmixing.

---

Step 4: Chill to Set

Transfer the pan to the refrigerator and let the fudge chill for at least 2 hours, or until fully firm. For best results and clean slicing, chill overnight.

---

Step 5: Slice and Serve

Once set, use the parchment overhang to lift the fudge out of the pan. Place it on a cutting board and slice into small squares using a sharp knife. Wipe the blade clean between each cut for perfect edges.

---

Notes

• Double the batch easily by using a 9×13-inch pan if you need more servings—just be sure to evenly double each ingredient.
• Use high-quality chocolate for the best texture and flavor. Cheaper chocolate chips may not melt as smoothly.
• Experiment with variations: swirl in peanut butter, white chocolate, or caramel for a fun twist on the classic version.

---

Watch Out for These Mistakes While Cooking

• Using high heat: Melting the chocolate mixture over high heat can scorch the chocolate and ruin the smooth texture. Always use low heat and stir constantly.
• Skipping the parchment paper: It may seem like a minor step, but without it, removing the fudge from the pan cleanly can be a sticky nightmare.
• Over-swizzling the marshmallow: Too much swirling blends the layers into one muddy color. Less is more here—aim for 4 to 5 elegant swirls.
• Not chilling long enough: Cutting into warm or partially set fudge leads to messy, crumbly slices. Give it proper chill time for clean results.
• Storing at room temperature in a warm kitchen: This fudge is best kept cool. Too much warmth and it’ll lose shape or become greasy.

While Easy Marshmallow Swirl Fudge is absolutely decadent on its own, it pairs beautifully with drinks, desserts, and even savory bites to create a well-rounded dessert board or gift box.

8 Recommendations:

1. Hot Coffee or Espresso
   The bitterness of coffee balances the rich sweetness of the fudge perfectly—especially dark roasts.

4. Fresh Berries
   Raspberries, strawberries, or blueberries add brightness and acidity that refresh the palate between bites.
5. Milk or Almond Milk
   A cold glass of milk (dairy or non-dairy) is a nostalgic and satisfying pairing, especially for kids.
6. Whipped Cream-topped Liqueurs
   Try Irish cream or coffee liqueur over ice with a touch of whipped cream for a grown-up pairing.
7. Shortbread Cookies
   Mild and buttery, shortbread doesn’t compete with the fudge and makes a lovely texture contrast.
8. Mini Cheesecakes or Cheesecake Bites
   For dessert tables, offer a variety—creamy cheesecake and fudge together create a luxurious bite.
