This marshmallow fudge recipe makes rich, creamy, melt-in-your-mouth fudge with classic marshmallow flavor!

A classic marshmallow fudge recipe is all about that smooth, melt-in-your-mouth bite!

What Makes Marshmallow Fudge So Good

Marshmallow creme doesn’t just add sweetness. It does three important things:

• Texture insurance: It prevents the sugar from crystallizing into grainy sadness.
• Creamy body: It helps the fudge stay smooth and sliceable.
• Classic flavor: It gives that nostalgic, old-school fudge taste people recognize instantly.

This is why the “fantasy fudge” style has been loved forever. It’s not trendy. It’s timeless. Like a good cashmere sweater, but edible.

Ingredients

The Fudge Base

• Granulated sugar – 3 cups
• Unsalted butter – ¾ cup (12 tbsp / 1½ sticks)
• Evaporated milk – ⅔ cup. (Do not swap for regular milk. Evaporated milk is thicker and gives the correct body.)
• Salt – ½ tsp
• Semi-sweet chocolate chips – 2 cups (12 oz)
• Milk chocolate chips – 1 cup (6 oz). (This combo gives deep chocolate flavor plus that classic fudge sweetness.)
• Marshmallow creme (Fluff) – 1 jar (7 oz)
• Pure vanilla extract – 2 tsp

Optional Mix-Ins (Pick One Personality, Don’t Overload)

• Chopped walnuts or pecans – 1½ cups
• Mini marshmallows – 1 cup (fold in at the end for gooey pockets)
• Crushed peppermint – ½ cup (holiday mode)
• Flaky sea salt – a pinch on top (for “expensive candy shop” vibes)

Before You Cook: Set Yourself Up Like A Pro

This recipe moves fast once it starts. If you pause to hunt for vanilla, you’ll end up with fudge that sets with an attitude.

Step 1: Prep The Pan

• Line a 9×13 pan with parchment paper, leaving overhang on the sides.
• Lightly butter the parchment (yes, even though it’s parchment).

This ensures the fudge releases like a dream.

Step 2: Pre-Measure Everything

Put each ingredient where you can grab it quickly.

• Chips in one bowl
• Marshmallow creme opened and ready (sticky stuff waits for no one)
• Vanilla measured
• Nuts/mix-ins ready if using

Step 3: Choose Your Texture Goal

• Want traditional, super smooth fudge? Skip nuts.
• Want old-school “holiday tray” fudge? Add nuts.

Both are perfect. Different moods.

The “Glossy, No-Grain” Method

(This is your catchy step title. Because this fudge is glossy, and grainy fudge is my enemy.)

Step 1: Build The Sugar Base

In a heavy saucepan over medium heat, add:

• Sugar
• Butter
• Evaporated milk
• Salt

Stir slowly and steadily as the butter melts and the mixture starts to look like wet sand turning into syrup.

You’re not trying to boil it yet—you’re dissolving sugar and making a smooth foundation.

Step 2: Bring It To A Real Boil (Not A Fake Bubble)

• Increase heat slightly to bring the mixture to a full rolling boil.
• A rolling boil means the entire surface is actively boiling and doesn’t stop when you stir.
• Once it hits a rolling boil, set a timer for 5 minutes.
• This timing is the heart of the recipe.

Step 3: Stir Like You Mean It For 5 Minutes

For the full 5 minutes:

• Stir constantly, scraping the bottom and corners.
• Keep the boil steady, not violent.
• Adjust heat if it starts climbing the pot like it’s trying to escape.
• What you’re preventing: scorching on the bottom and sugar crystals forming on the sides.

If You’re Using A Thermometer

• You’re aiming for 234°F (112°C), which is soft-ball stage.
• That is the temperature where fudge sets perfectly—firm but creamy.

Step 4: Remove From Heat And Add Chocolate Immediately

The second your timer hits 5 minutes:

• Remove the pot from heat.
• Add all chocolate chips.
• Let them sit for 60 seconds without stirring.
• This little pause melts the chips gently, which keeps the texture silky.

Step 5: Stir Until Smooth And Satin-Like

• Now stir until the chocolate fully melts and the mixture looks glossy and unified.
• No streaks.
• No lumps.
• No panic.

If a few chips resist, stir a little longer. The residual heat finishes the job.

Step 6: Add Marshmallow Creme And Vanilla (The Magic Moment)

• Add marshmallow creme.
• Add vanilla.
• Stir firmly until completely incorporated.
• It will look like it’s fighting you for a moment. That’s normal. Keep going until it becomes one smooth, thick, shiny mixture.

Step 7: Fold In Mix-Ins (If Using)

If adding nuts or mini marshmallows:

• Fold them in now, quickly but gently.
• Don’t overmix. Overmixing cools the fudge too fast and makes it harder to spread.

Step 8: Pour And Smooth Like A Calm Person

• Pour fudge into the prepared pan.
• Use a spatula to smooth the top.
• Tap the pan lightly on the counter 2–3 times to release air bubbles.
• If using flaky salt, sprinkle a tiny pinch on top while it’s still warm.

Cooling And Setting (Where People Mess It Up)

The Correct Way To Cool Fudge

• Let it cool at room temperature for 2 hours.
• Then refrigerate for 1–2 hours to fully set.
• Do not throw hot fudge straight into the fridge. Rapid temperature change can cause condensation, which messes with texture and makes the top look wet.

How To Know It’s Fully Set

• The surface feels firm when gently pressed.
• A knife cuts clean without dragging goo.

How To Slice Fudge Like It Came From A Candy Shop

This is where you go from “homemade” to “professional.”

• Lift fudge out using parchment overhang.
• Place on a cutting board.
• Use a large sharp knife.
• Run knife under hot water, wipe dry, then slice.
• Repeat hot-water wipe between cuts for clean edges.

Cut into:

• 1-inch squares for candy trays
• 2-inch squares for “I mean business” portions

Fudge is the kind of treat that rewards confidence. When you follow the timing, respect the boil, and stir like you’re in charge, you end up with glossy squares that taste like childhood plus excellent adult taste. Keep this marshmallow fudge recipe close, because once you make it, you become the person everyone asks to “bring dessert.”
