How to Make the Fruity Marshmallow Fudge
Step 1: Prepare Your Canvas
Line your pan with foil or parchment paper, creating a little hammock that’ll make removing and cutting your fudge a breeze later. This five-minute prep step saves so much hassle down the road, trust me!
Step 2: Create the Creamy Base
Melt those white chocolate chips and butter together over gentle heat. This isn’t a race, so keep the heat low and stir constantly. You’re looking for thick and creamy, not runny. Think of it as creating the perfect blank canvas for our colorful additions.
Step 3: Add the Secret Weapon
Here comes the genius part! That container of frosting isn’t just for cakes anymore. Once melted and stirred into our white chocolate mixture, it creates the perfect fudge texture without any of the traditional fudge-making anxiety. Let this mixture cool slightly, giving it an occasional stir to release heat.
Step 4: The Fun Explosion
Now for the magic! Fold in those colorful marshmallows and half the sprinkles. Work quickly but gently, you want them distributed throughout but not completely melted. Pour this rainbow-speckled goodness into your prepared pan and marvel at your creation.
Step 5: The Grand Finale
While the fudge is still soft, shower it with the remaining marshmallows and sprinkles. This creates a beautiful top layer that hints at the fun waiting inside. Now comes the hardest part, waiting for it to set completely before cutting into squares of joy!
Pro Tips for Making the Fruity Marshmallow Fudge
- Low and Slow: Keep your heat gentle when melting the chocolate and butter to prevent scorching.
- Cool Before Adding: Let the base cool for those full 10 minutes before adding marshmallows, otherwise they’ll melt completely and lose their distinct shapes.
- Chill Factor: For faster setting, pop the fudge in the refrigerator, but let it come to room temperature before serving for the best texture.
- Clean Cuts: Use a knife dipped in hot water and wiped dry between cuts for picture-perfect fudge squares.
How to Serve
- Dessert Platters: Arrange alongside cookies and brownies for a sweet treat assortment.
- Gift Giving: Stack squares in a decorative tin lined with parchment paper for a homemade gift that’ll earn you major points.
- Party Favors: Wrap individual pieces in wax paper and tie with ribbon for adorable take-home treats.
- Ice Cream Topping: Crumble a piece over vanilla ice cream for a dessert that’s over-the-top in the best possible way.

Make Ahead and Storage
Storing Leftovers
Keep your fudge in an airtight container at room temperature for up to a week, with parchment between layers to prevent sticking.
Freezing
This fudge freezes beautifully for up to three months! Wrap tightly in plastic wrap, then foil, and place in a freezer bag.
Thawing
Let frozen fudge thaw overnight in the refrigerator, then bring to room temperature before serving for that perfect fudgy texture.
FAQs
Can I use different flavored frosting instead of vanilla?
Absolutely! Try strawberry or cream cheese frosting for a different flavor profile. Just keep in mind it will change the base color of your fudge.
My white chocolate seems too thick when melting. What am I doing wrong?
White chocolate can be finicky. If it’s too thick, try adding a teaspoon of vegetable oil to help it melt more smoothly. Just be patient and keep the heat low.
Can I use regular-sized marshmallows instead of mini ones?
You can, but I’d recommend cutting them into quarters first. The mini marshmallows distribute more evenly throughout the fudge and create a better texture balance.
How do I know when the fudge is completely set?
The fudge should feel firm to the touch and not leave any residue on your finger. This typically takes 2-3 hours at room temperature or about 1 hour in the refrigerator.
This Fruity Marshmallow Fudge isn’t just a treat, it’s a mood-lifter in edible form! The combination of creamy white fudge, chewy fruit-flavored marshmallows, and festive sprinkles creates something that’s as fun to look at as it is to eat. Whether you’re making it for a special occasion or just because you deserve something delightful, this recipe brings pure joy in every colorful bite.
