- Lime zest (4 tablespoons plus extra for garnish): Injects fresh, zesty citrus notes that brighten every bite.

How to Make Key Lime Pie Fudge Recipe
Step 1: Prepare the Oven and Pan
Start by preheating your oven to 350 degrees Fahrenheit. Line a 9×13-inch baking dish with parchment paper to prevent sticking, then give it a quick spritz with non-stick spray. This ensures your fudge will come out in perfect squares without any fuss.
Step 2: Make the Graham Cracker Crust
In a large mixing bowl, combine the melted butter, sugar, and graham cracker crumbs. Stir everything together until the mixture looks uniformly dampened and crumbly. This blend will create a buttery, sweet crust that’s essential for the base of the fudge.
Step 3: Press the Crust Into the Pan
Firmly press the crust mixture into the bottom of your prepared baking dish. Use the back of a spoon or a flat measuring cup to compact it evenly—it should be about a half-inch thick to get that satisfying crunch in every bite.
Step 4: Bake the Crust
Pop the crust into the oven and bake for 8 to 10 minutes, or until it turns a lovely golden brown. This step not only adds flavor but ensures a sturdy base so that your fudge holds together perfectly. Once done, let it cool for about 30 minutes before moving on.
Step 5: Melt the Chocolate Mixture
As the crust cools, grab a large saucepan and set it over medium heat. Add the white chocolate chips, chopped white chocolate bar, and the sweetened condensed milk. Stir continuously until all the chocolate has melted into a smooth, creamy mixture—this rich base is what makes your fudge truly indulgent.
Step 6: Add the Lime and Vanilla Flavors
Remove the saucepan from heat and stir in the fresh lime zest, lime juice, and vanilla extract. The lime zest and juice infuse that unmistakable key lime pie tang, while the vanilla extract adds a welcoming depth to the sweetness. Make sure everything is mixed thoroughly for even flavor.
Step 7: Assemble the Fudge
Pour the luscious lime-infused chocolate mixture evenly over the baked and cooled graham cracker crust. Spread it gently to cover every inch, ensuring that each slice will have a heavenly bite of both crust and creamy fudge.
Step 8: Garnish and Chill
Zest a fresh lime directly over the top of the fudge for a pop of vibrant color and a hint of extra citrus aroma. Then, refrigerate your fudge overnight to allow it to set completely and develop that perfect sliceable texture you’re aiming for.
Step 9: Cut and Enjoy!
Once firm, lift the fudge out of the pan using the parchment paper. Using a sharp knife, cut into 2-inch squares and get ready to delight in each rich, tangy bite of your homemade Key Lime Pie Fudge Recipe!
How to Serve Key Lime Pie Fudge Recipe
Garnishes
Adding a little finishing touch can really elevate your fudge. Try sprinkling some extra lime zest on top, or even a few crushed graham crackers to emphasize that classic pie feel. A small dollop of whipped cream or a fresh mint leaf on each piece can also add a beautiful touch and enhance the presentation.
Side Dishes
This fudge pairs wonderfully with simple accompaniments. A cup of strong coffee or a bright herbal tea balances the sweetness. For parties, serve alongside fresh berries or a tropical fruit salad to complement the lime’s refreshing zest.
Creative Ways to Present
Think beyond the plate! Package your Key Lime Pie Fudge Recipe in cute little boxes or cellophane bags tied with a ribbon for lovely homemade gifts. Or lay the fudge pieces out on a pretty platter with edible flowers and lime wedges for an eye-catching dessert table display.
Make Ahead and Storage
Storing Leftovers
After enjoying your fudge, keep any leftovers stored in an airtight container at room temperature for up to a week. This helps maintain the creamy texture and fresh lime flavor without the fudge drying out.
Freezing
If you want to make this Key Lime Pie Fudge Recipe well in advance, it freezes beautifully. Wrap individual pieces tightly in plastic wrap and place them in a freezer-safe container or bag. They can keep for up to 3 months and thaw quickly at room temperature when you’re ready to enjoy.
Reheating
Your fudge is best enjoyed chilled or at room temperature, so reheating isn’t typically necessary. But if you prefer a softer texture, gently warming a piece in your hands or briefly in a low oven can make it wonderfully melty and decadent.
FAQs
Can I use regular lime instead of key lime for this fudge?
Absolutely! Regular limes will work just fine if you can’t find key limes. The flavor will be slightly less tart, but still bright and refreshing, keeping the spirit of the Key Lime Pie Fudge Recipe alive.
What kind of white chocolate works best?
Using high-quality white chocolate, like Ghirardelli or a premium white chocolate bar, is key for the best texture and flavor. Cheaper white chocolate may not melt as smoothly or deliver the same creamy richness.
Is the graham cracker crust necessary?
The graham cracker crust provides that classic pie texture and a delicious buttery crunch that contrasts perfectly with the creamy fudge. While you could skip it, your Key Lime Pie Fudge Recipe wouldn’t have the same iconic character.
How long does this fudge keep at room temperature?
Stored properly in an airtight container, this fudge stays fresh at room temperature for about a week. Beyond that, refrigeration or freezing is recommended to maintain quality.
Can this recipe be made vegan or dairy-free?
This particular recipe relies on dairy-based ingredients like butter, condensed milk, and white chocolate, which makes vegan adaptations a bit challenging. However, you can experiment with coconut condensed milk and vegan white chocolate alternatives to create your own twist on the Key Lime Pie Fudge Recipe.
