Ingredients
Marshmallow Fluff
Marshmallow fluff gives this dessert its signature light, sweet marshmallow flavor and smooth texture. Use a standard jar of marshmallow creme or fluff.
Sweetened Condensed Milk
Sweetened condensed milk adds richness and sweetness while helping create a creamy consistency.
Because it is already sweetened, there’s no need to add additional sugar.
Chocolate Chips
Chocolate chips provide the rich chocolate flavor that pairs perfectly with marshmallow.
Semi-sweet chocolate chips are a great choice because they balance the sweetness, but milk chocolate or dark chocolate chips can also be used.
How to Make 3-Ingredient Slow Cooker Marshmallow Fluff Dessert
Step 1: Prepare the Slow Cooker
Lightly grease the inside of your slow cooker with nonstick cooking spray.
This helps prevent sticking and makes cleanup easier.
Step 2: Add the Ingredients
Add the marshmallow fluff, sweetened condensed milk, and chocolate chips to the slow cooker.
Spread the ingredients out as evenly as possible.
Step 3: Cook on Low
Cover the slow cooker and cook on LOW for about 1 to 2 hours.
Stir every 20 to 30 minutes to help the chocolate melt evenly and prevent the mixture from sticking around the edges.
Slow cookers vary in temperature, so begin checking the mixture after about an hour.
Step 4: Stir Until Smooth
Once the chocolate has melted, stir everything thoroughly until the dessert is completely smooth and creamy.
There should be no large pieces of unmelted chocolate remaining.
Step 5: Serve Warm
Spoon the warm marshmallow dessert into small bowls and serve immediately.
For an extra fun presentation, serve it as a dessert dip with graham crackers, cookies, pretzels, or fresh fruit.
Tips for the Best Marshmallow Fluff Dessert
Cook Slowly
Use the LOW setting whenever possible. Chocolate and marshmallow can scorch if exposed to excessive heat.
Stir Frequently
Stirring regularly helps distribute the heat and ensures that the chocolate melts evenly.
Don’t Overcook
As soon as the ingredients are completely melted and smooth, the dessert is ready. Overcooking can make the mixture excessively thick.
Serve Immediately
This dessert is especially delicious when warm and gooey. It will naturally become thicker as it cools.
Keep the Lid On Between Stirs
Try to minimize how long the lid stays off while stirring. Slow cookers lose heat quickly when uncovered.
Easy Variations
Peanut Butter Chocolate
Replace some of the chocolate chips with peanut butter chips for a delicious chocolate-peanut butter combination.
White Chocolate
Use white chocolate chips instead of regular chocolate chips for a sweeter, creamy variation.
S’mores Dessert
Serve the warm mixture with crushed graham crackers and extra marshmallows for a s’mores-inspired treat.
Chocolate Mint
Use chocolate mint chips or add a small amount of mint extract for a refreshing twist.
Add Crunch
Stir chopped pecans, walnuts, or crushed pretzels into individual servings for added texture.
Caramel Marshmallow
Drizzle caramel sauce over the finished dessert before serving.

Can I Make This Dessert Ahead of Time?
Yes. You can prepare the dessert ahead of time and gently reheat it before serving.
Since the mixture becomes thicker as it cools, stir in a small splash of milk if needed while reheating to loosen the consistency.
How to Store Leftovers
Allow leftover dessert to cool before transferring it to an airtight container.
Store it in the refrigerator for up to 3 to 4 days.
To reheat, warm individual portions in the microwave in short intervals, stirring between each interval. You can also gently reheat the dessert in the slow cooker.
Can I Freeze Marshmallow Fluff Dessert?
Freezing is not recommended if you want the best texture. The creamy marshmallow and condensed milk mixture may become grainy or change consistency after thawing.
For the best results, refrigerate leftovers and reheat gently.
Frequently Asked Questions
Can I use mini marshmallows instead of marshmallow fluff?
Yes, although the finished texture will be different. Marshmallow fluff creates a smoother and creamier dessert, while mini marshmallows will produce a more stretchy, melted-marshmallow texture.
Can I use milk chocolate chips?
Yes. Milk chocolate chips will give the dessert a sweeter chocolate flavor. Semi-sweet chocolate provides a little more balance.
Can I use dark chocolate?
Absolutely. Dark chocolate chips are a good option if you prefer a richer, less sweet chocolate flavor.
Can I make this dessert without a slow cooker?
Yes. Combine the ingredients in a saucepan and warm them over very low heat, stirring constantly until smooth. Avoid high heat because chocolate can burn easily.
Why is my dessert too thick?
The dessert naturally thickens as it cools. If it becomes too thick, gently warm it and stir in a small amount of milk until you reach your preferred consistency.
Can I double the recipe?
You can, provided your slow cooker is large enough. Avoid filling the slow cooker too close to the top, and allow enough room for thorough stirring.
