A quiet Sunday afternoon, just a simple meet-up with an old friend over coffee — no plans for dessert, maybe a granola bar if the conversation stretched on. But when she walked in holding a small tin lined with wax paper, the faint scent of lime trailing behind her, I had a feeling she brought more than just stories. “Try one,” she said, sliding the tin toward me like she was letting me in on a secret. “They’re Key Lime Truffles. Taste like summer.” One bite and I knew she was right — creamy, zesty, and bright, like sunshine wrapped in dessert form.
The outside was dusted in graham cracker crumbs, but the inside was pure velvet — creamy, sweet, and citrus-bright. It was like cheesecake had decided to wear a sundress. I couldn’t stop at one. That night, I texted her asking for the recipe, and she sent it with zero hesitation. The ingredient list was short, but the flavor was something special.
The next day, I found myself zesting limes with the kind of energy usually reserved for holiday baking. That infusion of lime zest into cream? It blooms into something floral, citrusy, and undeniably sunny. These Key Lime Truffles are now a staple in my fridge — perfect for a light treat after dinner, a tea-time delight, or even a refreshing surprise on a dessert platter.
Short Description
These Key Lime Truffles are creamy, citrus-packed bites rolled in graham cracker crumbs for a refreshing twist on classic truffles — like a key lime pie in dessert ball form.
Key Ingredients
- 1/4 cup heavy whipping cream
- 1/4 cup sweetened condensed milk
- 4 tablespoons lime zest (freshly grated)
- 2 cups white chocolate chips
- 2 tablespoons lime juice (preferably fresh Key lime juice)
- 1 tablespoon unsalted butter, softened
- 2 cups crushed graham crackers
Tools Needed
- Medium saucepan
- Whisk
- Mixing bowl
- Plastic wrap
- Tablespoon or small cookie scoop
- Shallow dish for coating
- Tray or plate for setting
Cooking Instructions
Step 1: Infuse the Cream Mixture
In a medium saucepan over medium heat, combine the heavy whipping cream, sweetened condensed milk, and lime zest. Stir constantly until the mixture starts to simmer gently. As soon as bubbles form around the edges, remove it from the heat and allow it to sit for 30 minutes. This resting time allows the lime zest to deeply infuse into the cream, creating a fragrant citrus base.
Step 2: Reheat and Add Chocolate
Return the infused cream mixture to the stove over low heat. Let it come back to a gentle simmer. Remove from heat, then immediately whisk in the white chocolate chips, lime juice, and softened butter. Whisk until the mixture is smooth, creamy, and fully incorporated. If the chocolate isn’t melting evenly, you can place it back over low heat briefly, stirring continuously.
Step 3: Chill Until Firm
Transfer the mixture to a clean mixing bowl. Press a piece of plastic wrap directly onto the surface to prevent a skin from forming. Refrigerate for at least 2 hours, or until the mixture is firm enough to handle without sticking.
Step 4: Scoop and Shape
Using a tablespoon or a small cookie scoop, portion out the chilled truffle mixture. Roll each portion between your hands to form smooth, round balls. If the mixture is too soft, place it back in the fridge for another 20–30 minutes.
Step 5: Coat in Graham Cracker Crumbs
Place the crushed graham crackers into a shallow dish. Roll each truffle in the crumbs until fully coated, gently pressing to help the coating stick.
Step 6: Set and Serve
Arrange the truffles on a tray or plate. Refrigerate them for an additional 20–30 minutes to set fully before serving. Store any leftovers in an airtight container in the fridge for up to 5 days.

Mistakes to Avoid & Solutions
Mistake 1: Overheating the cream mixture
Solution: Only bring the cream to a gentle simmer, not a boil. High heat can scald the dairy and curdle the mixture.
Mistake 2: Not letting the zest infuse
Solution: Letting the lime zest sit in the warm cream for 30 minutes is crucial for that signature citrus flavor. Don’t skip this step.
Mistake 3: Chocolate not melting properly
Solution: If your chocolate doesn’t melt smoothly, warm the mixture gently again while stirring continuously until smooth. Avoid overheating, or it might seize.
Mistake 4: Truffle mixture too soft to roll
Solution: Chill longer. If it’s still soft after 2 hours, give it another 30 minutes. You can also briefly place it in the freezer to speed things up.
Mistake 5: Graham cracker coating doesn’t stick
Solution: Roll the truffles when they’re just firm enough to handle but not too cold. A slight stickiness helps the crumbs adhere better.

FAQs
1. Can I use regular limes instead of Key limes?
Yes! While Key limes offer a unique tartness, regular limes work well too. Just use freshly squeezed juice for the best flavor.
2. What can I use instead of white chocolate chips?
You can use chopped white chocolate bars, but make sure it’s high-quality chocolate that melts smoothly.
3. Are these truffles too sweet?
The sweetness is balanced by the lime juice and zest. If you prefer a tangier flavor, you can slightly reduce the condensed milk or add extra lime zest.
4. Can I make these dairy-free?
Yes, use coconut cream instead of heavy cream, dairy-free white chocolate, and a plant-based condensed milk. The texture may be slightly different but still delicious.
5. How many truffles does this recipe make?
This recipe makes about 20–24 truffles, depending on the size of your scoops.
Tips & Tricks
Zest the limes before juicing — it’s much easier that way
Use a microplane for fine zest that infuses better
For a prettier finish, dust the truffles with extra zest after coating
Add a pinch of salt to the mixture to balance sweetness
Chill your hands slightly before rolling to prevent sticking
Recipe Variations
Coconut Key Lime Truffles
Swap 1/2 cup of white chocolate chips with shredded coconut. Roll finished truffles in toasted coconut instead of graham crackers for a tropical flair.
Key Lime Cheesecake Truffles
Add 2 oz of softened cream cheese to the mixture during Step 2 for a rich cheesecake-like texture and tang.
Key Lime Raspberry Truffles
Add 2 teaspoons of freeze-dried raspberry powder to the cream while infusing. The fruity note pairs beautifully with lime.
Chocolate-Dipped Key Lime Truffles
Skip the graham cracker coating. Chill the truffles, then dip them in melted dark or milk chocolate and let them set on parchment paper.

Key Lime Truffles burst with a bright and playful charm that’s hard to resist.
