How to Make Key Lime Fudge Recipe
Step 1: Prepare Your Baking Dish
Start by lining an 8×8-inch square baking dish with parchment paper, leaving an overhang on the sides. This little trick makes it a breeze to lift the fudge out once it’s set without any mess or crumbling.
Step 2: Melt the Base Ingredients
In a saucepan set over medium-low heat, combine the white chocolate chips, sweetened condensed milk, and unsalted butter. Stir constantly to ensure everything melts evenly and transforms into a smooth, glossy mixture—a critical step for that flawless fudge texture.
Step 3: Add the Key Lime Flavors
Once your chocolate base is melting into a luscious, smooth sauce, remove it from heat. Stir in the fresh key lime zest and juice, vanilla extract, a pinch of salt, and the optional green food coloring. Mix swiftly to evenly distribute all those bright, zesty flavors that give this fudge its signature zing.
Step 4: Pour and Chill
Pour the mixture quickly into your prepared dish, smoothing out the top with a spatula so it sets evenly. This step locks in that creamy finish and creates a beautiful surface. Then, pop it into the refrigerator for at least three hours until it’s firm to the touch and ready to slice.
Step 5: Slice and Serve
Once chilled and set, use the parchment overhang to lift the fudge out of the pan. Cut it into 36 small squares, perfect for sharing or keeping all to yourself for those moments when you need a sweet pick-me-up.
How to Serve Key Lime Fudge Recipe
Garnishes
Enhance your Key Lime Fudge Recipe with a sprinkle of extra key lime zest or a few finely chopped pistachios for a pop of color and crunch. A light dusting of powdered sugar can also add a delicate, snowy finish that makes these treats look as festive as they taste.
Side Dishes
This fudge pairs beautifully with a simple cup of hot tea or coffee, balancing its richness. For a more indulgent experience, serve alongside fresh berries or a dollop of whipped cream to complement the citrusy notes with creamy, lightly sweet contrasts.
Creative Ways to Present
Get playful by arranging your fudge squares in a decorative box with tissue paper for gifting. Alternatively, serve them on a bright, tropical-themed platter adorned with lime slices and edible flowers to bring a sunny vibe to any party or gathering.
Make Ahead and Storage
Storing Leftovers
Keep your Key Lime Fudge Recipe fresh by storing the squares in an airtight container in the refrigerator. This will maintain their creamy texture and vibrant flavor for up to one week, so you can enjoy them over several days without any loss in quality.
Freezing
If you want to stash some away for later, you can freeze the fudge squares. Wrap each piece individually in plastic wrap and place them in a freezer-safe container. They’ll keep for up to 2 months and thaw quickly at room temperature when you’re ready for a sweet treat.
Reheating
Fudge is best enjoyed cold or at room temperature, but if you prefer it a little softer, let it sit out for 15 to 20 minutes before serving. Avoid microwaving, as it can alter the texture and cause the fudge to become grainy or too melty.
FAQs
Can I use regular lime instead of key lime?
Absolutely! While key limes offer a unique, slightly more floral flavor, regular limes can be used as a convenient substitute and will still produce delicious results.
Is it necessary to add food coloring?
Nope, the food coloring is entirely optional and just adds a fun, subtle green tint. The fudge will taste just as amazing without it, especially with all those fresh key lime flavors shining through.
How long does it take for the fudge to set?
It usually takes about 3 hours in the refrigerator for the fudge to firm up completely. If you want to speed things up, you can place it in the freezer for about 30 to 45 minutes, but watch carefully so it doesn’t freeze solid.
Can I make this recipe dairy-free?
Since this recipe relies on white chocolate chips and sweetened condensed milk, substituting for a dairy-free version can be tricky. However, there are dairy-free white chocolate alternatives and condensed milk substitutes on the market that might work, though the texture may vary slightly.
What’s the best way to cut the fudge without it crumbling?
Using a sharp knife warmed under hot water and wiped dry before slicing helps create clean, smooth cuts and minimizes crumbling. Cutting slowly and with a gentle sawing motion also preserves each perfect square.
