Marshmallow Fluff Fudge with Pecans

Butter melts first, then everything gets hot and thick and you’re basically done before you know it. Four hours sounds long but most of that’s just sitting in the fridge. Seven minutes of actual work. Twenty-seven if you count the waiting around part.

Why You’ll Love This Marshmallow Fudge

No bake involved—technically. Heat the mixture on the stove, that’s it. No oven. Done before your coffee gets cold.

Marshmallow creme makes it different. Not the dense brick fudge you’re used to. This one breaks clean, melts fast on your tongue. The fluff aerates everything.

Pecans add actual texture. Crunch that matters. Swaps for walnuts if you hate pecans, but pecans are better here.

Keeps forever if you actually have the willpower. Wrapped airtight, stays creamy for a week. Probably longer—never tested.

Better cold. Way better cold. Don’t even try it warm.

What You Need for Marshmallow Chocolate Fudge

One cup butter softened. Not warm, not cold. Soft. There’s a difference.

Evaporated milk. Not condensed. Everyone mixes these up. Evaporated is thinner. Condensed is thick and sweet and wrong for this.

Three cups sugar. Granulated works. Raw sugar works the same.

Two cups semi-sweet chocolate chips. Dark chocolate burns easier. Milk chocolate’s too soft. Semi-sweet is the middle ground.

Seven ounces marshmallow creme. The jar stuff. Or homemade if you have egg whites and time—mix egg white, corn syrup, and sugar into fluff. But the jar is faster.

One cup chopped pecans, toasted. Toasting matters. Brings out the oil, kills the raw taste. Walnuts work but they’re stronger, almost bitter. Pecans sit quiet.

Vanilla extract. One teaspoon. Pure, not imitation.

How to Make Chocolate Fudge with Marshmallow Fluff

Line an 8x8 pan with parchment. Extend it past the edges by a couple inches so you can grab it later and pull the whole block out. Grease under the paper if you’re nervous about sticking. Get this done before you start heating anything.

Medium heat. Butter goes in first and melts. Then evaporated milk. Then sugar. Stir constantly. This is non-negotiable. The bottom burns if you stop paying attention. Use a heavy-bottom saucepan—uneven heat kills you here.

Clip a candy thermometer to the side. You’re watching for 240 degrees Fahrenheit. Soft ball stage, technically. Higher than regular fudge needs but the marshmallow changes things. The mixture gets glossy first, then thick. Bubbles that were tiny and fast become big and sluggish. When you dip the spatula, they pop slow. That’s when you know it’s close.

Stop stirring so much now but don’t stop completely.

Pull it off heat the second the thermometer hits 240. Off. Done. Don’t wait.

Dump in all the chocolate chips at once and stir hard. They melt into the hot base fast. The color deepens. Smell changes. Everything gets dark and slick. Then dump the vanilla and marshmallow creme in together. The texture looks wrong for a second—puckers, gets fluffy, strange. Keep folding. The fluff breaks down and distributes. You want no visible chunks, just a velvety shine. Glossy. No streaks.

Fold in the pecans last. Toasted pecans. The toasting thing actually matters.

How to Get Marshmallow Fudge to Set Right

Transfer everything to the pan immediately. Scrape the sides, get all of it. Tap the pan hard on the counter a few times. Air bubbles get trapped and they ruin the texture if you don’t tap them out.

Leave it at room temperature for 25 to 35 minutes. It’ll frost over on top but stay soft enough underneath. Then straight into the fridge. Minimum three hours. Some people say four. Three works.

You’ll know it’s ready when a cold knife slides through and doesn’t stick. The snap test—cut a corner piece and snap it in half. Should snap clean. No gumminess. No soft spots.

Cut it with a sharp serrated knife. Heat the knife under hot water first if you want cleaner edges. 36 squares if you do six by six cuts. Or four by four for bigger pieces. Up to you.

Keep it in the fridge. Room temperature makes it soft and messy. Wrapped tight in plastic stops it from drying out or picking up fridge smells.

No Bake Fudge Tips and Common Mistakes

Sugar gets grainy if you overcook or stir while it’s cooling. Don’t stir while it sets. Just leave it alone.

Chocolate doesn’t fully melt? Add a splash of cream and stir gently off heat. Or reheat the pan for 30 seconds. Not back on the burner—just off heat, keep stirring.

Marshmallow spread looks similar to marshmallow creme but it’s not the same. The spread has tiny sugar crystals. Those crystals cause texture problems. Avoid it. Get the creme.

Butter swaps for coconut oil if you’re doing that but the flavor shifts. Noticeably. Not bad, just different.

Fudge too soft? Fridge it longer. Or freezer for 15-minute bursts. It hardens fast in the freezer but can turn grainy if you overdo it.

Homemade marshmallow fluff works but it’s extra steps. Egg white, corn syrup, sugar mixed until fluffy. If you’re making marshmallow anyway, use it. Otherwise buy the jar.

Best flavor sits a day or two. The marshmallow and chocolate meld and get quieter, smoother. But immediately after chilling is fine too. No bake just means no oven, not that it’s instant.

Prep:

Cook:

Total:

4h 10min

Servings:

36 servings

Ingredients

• 1 cup unsalted butter softened
• 11 oz evaporated milk not condensed
• 3 cups granulated sugar refined or raw
• 2 cups semi-sweet chocolate chips
• 1 teaspoon pure vanilla extract
• 7 oz marshmallow creme substitute with homemade marshmallow fluff (egg white, corn syrup, sugar)
• 1 cup chopped pecans toasted, swaps walnuts

Method

1. Prepare Pan
2. 1 Heavy 8x8 square pan lined with parchment paper. Extend paper sides past edges 2 inches for leverage when unmolding fudge. Grease lightly under paper if worried about sticking. Setup before heat.
3. Cook Sugar Mixture
4. 2 Medium heat. Butter melts first. Add evaporated milk then sugar. Constant stir avoid scorching bottom. Use heavy-bottom saucepan for even heat, candy thermometer affixed. Target soft ball stage around 240 F, higher than usual fudge clue but necessary with marshmallow fluff addition. Watch temp rise not just timer. Mixture thickens, glossy sheen; bubbles become sluggish, big and slow before dip at stage. Slow your stir pace now but don't stop.
5. Incorporate Chocolate
6. 3 Remove pan immediately off heat once 240 F hit. Add the chocolate chips fast, vigorously stir to melt chocolate fully into hot base. Mixture darkens, aroma deepens, chocolate slick covering spatula. Quickly dump vanilla and marshmallow fluff. Texture puckers, glossy goop morphs into fluffy yet dense mass. Keep folding until no fluffy chunks visible. You want a velvety shine without streaks. Then fold in chopped pecans, toasted to bring oil and crunch without bitterness. Change from walnuts due to stronger flavor preference noticed over batch #4.
7. Set and Chill
8. 4 Transfer fudge quickly to parchment lined pan. Scrape all mixture out or waste lurks. Tap sides hard on counter to shift air bubbles trapped. Rest 25-35 minutes at room temp frosting over but not stiff. Then, refrigerate minimum 3 hours until firm to melee cut test. Should snap clean with no gumminess. Use sharp serrated or chef knife, warmed if needed to slice even 36 squares 6 by 6. Keep refrigerated to avoid melty mess when serving. Store leftovers wrapped airtight to retain texture.
9. Tips & Troubleshooting
10. 5 Sugar grainy texture? Overcooking or stirring while cooling. Under-melted chips? Add splash cream or reheat gently off heat while stirring. Marshmallow fluff swap okay with homemade but avoid marshmallow spread with tiny sugar crystals—causes choke in texture. Butter substitute possible with coconut oil, but flavor shifts. If fudge soft, fridge longer or try chill in freezer 15 min increments. Best flavor post-chill but can sit out 20 min before devouring. Make sure pan lined well for folds or fudge fights removal.
11. Serving
12. 6 Crunch of nuts. Sweet marshmallow bite lingers with bittersweet chocolate finish. Dense to touch but melts creamy; breaks gently like good fudge should. Take your time savoring pieces with coffee or milk. Leftover fudge better after day or two if you can resist.

Frequently Asked Questions About Pecan Chocolate Fudge

Can you use condensed milk instead of evaporated milk? No. Condensed is sweetened, thick. Evaporated is what the recipe needs. Different products.

How long does homemade marshmallow fudge keep? Wrapped tight in the fridge, about a week. Cold keeps it stable. Room temp and it starts to soften after an hour. Freezer lasts months but texture changes slightly.

What if you don’t have a candy thermometer? The soft ball test works. Drop a small spoonful in cold water. Roll it into a ball with your fingers. If it holds but squishes, that’s 240. If it’s still sticky, not done yet.

Why is toasting pecans necessary for no bake fudge? Raw pecans taste flat. Toasting releases the oils, brings out flavor. 350 degrees for 8 minutes, just watch them. Burns fast.

Can you make this butter chocolate fudge without marshmallow fluff? Technically yes. It becomes regular fudge. Denser, less interesting. The fluff is kind of the point.

Does pecan chocolate fudge harden properly at room temperature? Takes hours. The marshmallow makes it slower to set. Fridge is not optional. Three hours minimum.
