Ingredients You’ll Need
The simplicity of this recipe is part of its charm. Each ingredient is carefully chosen to bring out the creamy texture, the vivid lime flavor, and the delightful visual appeal of the fudge. These essentials come together effortlessly, making the preparation as enjoyable as the final bite!

- Key lime juice (fresh or bottled): Brings a tangy balance that complements the sweetness beautifully.
- Vanilla extract: A subtle warmth that rounds out the flavors and deepens complexity.
- Pinch of salt: Vital for highlighting all the flavors and preventing the fudge from tasting overly sweet.

How to Make Key Lime Fudge Recipe
Step 1: Prepare your pan
Start by lining an 8×8-inch baking pan with parchment paper. Make sure the edges overhang the pan’s sides to help you easily lift out the fudge later. This simple step ensures your fudge sets up perfectly and comes out clean without sticking or breaking apart.
Step 2: Melt the chocolate mixture
Place a medium saucepan over low heat and combine the white chocolate chips, sweetened condensed milk, and unsalted butter. Stir constantly to gently melt the chocolate and create a smooth, even mixture without any lumps or scorched spots. Patience here is key to achieving that luscious texture.
Step 3: Add the zesty ingredients
Once your chocolaty base is silky and uniform, remove it from the heat. Quickly stir in the key lime juice, zest, vanilla extract, salt, and, if you want that classic green hue, a drop or two of green food coloring. Mixing swiftly ensures everything combines beautifully and the lime flavor stays fresh and bright.
Step 4: Pour and chill
Pour the fudge mixture into your prepared pan. Use a spatula to smooth out the top for an even surface. Sprinkle extra lime zest over the top to enhance the aroma and add a lovely pop of color. Refrigerate for at least 3 to 4 hours until the fudge is completely firm and ready to cut into squares.
How to Serve Key Lime Fudge Recipe
Garnishes
To elevate your fudge experience, a simple garnish of additional key lime zest sprinkled on top offers freshness and a hint of texture. You could also get creative by dusting a tiny bit of powdered sugar for a wintery look or popping on white chocolate curls for a playful twist.
Side Dishes
Key Lime Fudge pairs beautifully with light, fruit-based sides like fresh berries or a tropical fruit salad to enhance its citrus notes. For something more indulgent, serve alongside coconut macaroons or a scoop of vanilla ice cream for a decadent treat.
Creative Ways to Present
Looking to impress guests? Cut the fudge into perfect bite-sized squares, then arrange them on a decorative platter with lime slices and mint leaves for a vibrant display. You might even layer the fudge with graham cracker crumbs in individual cups for a no-bake key lime pie-inspired dessert parfait.
Make Ahead and Storage
Storing Leftovers
Keep your Key Lime Fudge in an airtight container in the refrigerator to maintain its firm, creamy texture. It will stay fresh for up to one week, making it an excellent treat to have on hand for whenever a sweet craving strikes.
Freezing
If you want to extend the life of your fudge, wrap it tightly in plastic wrap and place in a freezer-safe container or bag. Frozen fudge can last for up to three months and is easy to thaw overnight in the fridge before enjoying.
Reheating
Since fudge is best enjoyed chilled, reheating is usually unnecessary. However, if you prefer it slightly softer, simply let it sit at room temperature for 10-15 minutes before serving, allowing it to soften just enough without losing its structure.
FAQs
Can I use regular lime instead of key lime?
Yes, regular lime can be a substitute in a pinch, though key limes have a distinct, slightly sweeter and more floral citrus flavor that makes this fudge truly special. If you use regular lime, consider adjusting the zest amount to balance the tang.
Is this recipe gluten-free?
Absolutely! The ingredients used in this Key Lime Fudge Recipe are naturally gluten-free, making it a perfect dessert option for those avoiding gluten.
Can I make this fudge dairy-free?
This recipe relies on dairy ingredients like butter and sweetened condensed milk, so to make it dairy-free, you would need to find suitable substitutes such as vegan butter and coconut condensed milk, but the texture and flavor might vary.
What is the best way to cut fudge without it crumbling?
Use a sharp knife and press firmly in one smooth motion. For cleaner cuts, chill the fudge thoroughly before slicing and warm the knife with hot water, wiping it dry between cuts to prevent sticking.
Can I add mix-ins to this fudge?
Yes! While the classic Key Lime Fudge Recipe shines on its own, you could fold in crushed graham crackers for texture or white chocolate chips for extra creaminess. Just be careful not to overwhelm the signature lime flavor.
Final Thoughts
If you’re searching for a dessert that captures the bright spirit of summer within every bite, this Key Lime Fudge Recipe is exactly what you need. It’s effortless, irresistibly tasty, and bound to bring a smile to anyone who tries it. Don’t hesitate—give it a go and enjoy the wonderful combination of creamy, sweet, and zesty all at once!
