Key Lime Pie Mojito – Creamy, Minty, Boozy Bliss

What an absolute joy it is to welcome you here today. I just want to start by saying thank you — truly — for spending a few minutes with me. If you’ve found your way here, I’m guessing you’re craving something refreshing, a little indulgent, and definitely out of the ordinary. Well, you’re in for a treat. The moment I stirred up this Key Lime Pie Mojito, I knew I had to share it. This isn’t your average cocktail. It’s a luscious, creamy twist on a mojito, inspired by the silky tang of key lime pie. The first sip? Pure sunshine.

What is a Key Lime Pie Mojito?

The Key Lime Pie Mojito is a delightful mash-up of a classic mojito and the beloved Southern dessert, key lime pie. You get the zesty lime and cooling mint from the mojito base, but with a decadent twist: sweetened condensed milk brings a creaminess that mimics the pie’s rich filling. Add a graham cracker rim, a dollop of whipped cream, and a fizzy splash of club soda, and you’ve got a dessert-meets-cocktail experience that’s equal parts refreshing and indulgent.

It’s the kind of drink that makes you pause and say, “Wait, how did I never think of this before?” It’s tangy, smooth, lightly sweet, and so unique — a total showstopper served in a glass.

Why You’ll Love This Key Lime Pie Mojito

This isn’t just a pretty cocktail (although it certainly turns heads at a party). Here’s why I think this one’s going to steal your heart — and your taste buds:

• Unexpected and unforgettable – A cocktail with pie vibes? Yes, please. This is one of those drinks people remember.
• Perfect for summer entertaining – It’s chilled, fizzy, and vibrant. Basically made for patio nights and poolside lounging.

What Does It Taste Like?

The flavor is a perfect balance of bright citrus and creamy sweetness. The key lime juice cuts through with a zingy tartness, mellowed by the rich, smooth texture of sweetened condensed milk. The mint adds a cool, refreshing lift, while the white rum brings subtle warmth and depth. Then there’s the club soda — giving it a crisp, bubbly finish. Topped with whipped cream and graham cracker crumbles, the whole thing becomes a cocktail you might need a spoon for. It’s tropical, dreamy, and truly like sipping a pie.

Ingredients (Serves 2)

• ½ cup white rum
• ¼ cup fresh key lime juice (or regular lime juice if needed)
• 2 tablespoons sugar
• 8–10 fresh mint leaves
• ½ cup club soda
• ½ cup sweetened condensed milk
• Ice (as needed)
• Whipped cream (for topping)
• Crushed graham crackers (for garnish)
• Lime slices and mint sprigs (optional garnish)

Kitchen Tools You’ll Need

• Cocktail shaker or small pitcher
• Muddler or the back of a spoon
• Measuring cups and spoons
• Serving glasses (highball, mason jars, or cocktail glasses work great)
• Small plate (for rimming glasses with graham crackers)

Ingredient Substitutions and Additions

The great thing about this recipe is how flexible it is. You can easily tailor it to suit your preferences or what you’ve got in your pantry.

• No key limes? Regular limes will do the trick. You’ll still get plenty of zing.
• Different spirits: Swap white rum for coconut rum, spiced rum, or even tequila for a unique twist.
• Make it tropical: Add a splash of pineapple juice or mango purée for extra island vibes.
• Dairy-free version: Use coconut condensed milk for a vegan-friendly, tropical alternative.
• Sweetness level: If sweetened condensed milk is too rich for you, try using just ⅓ cup or add more lime juice to balance the sweetness.
• Frozen style: Toss all the ingredients in a blender with ice to make a frozen mojito slushie.

Step-by-Step Instructions

Step 1: Prepare the Glasses

Take your serving glasses and run a wedge of lime around the rim. Dip the rims into a plate of crushed graham crackers to coat them. This gives that perfect “pie crust” touch. Drop a few lime slices and fresh mint leaves into each glass for an aromatic base layer.

Step 2: Muddle the Base

In a cocktail shaker or small pitcher, combine the fresh mint leaves, sugar, and lime juice. Use a muddler (or the back of a spoon) to gently crush the mint, releasing its oils while dissolving the sugar into the juice.

Step 3: Add the Liquids

Pour in the white rum and sweetened condensed milk. Add plenty of ice and shake (or stir vigorously if using a pitcher) until everything is well chilled and the milk has fully blended, creating a creamy texture.

Step 4: Assemble the Cocktail

Strain the mixture into your prepared glasses filled with ice. Leave a little room at the top and pour in a splash of club soda for fizz.

Step 5: Garnish and Serve

Top each glass with a generous swirl of whipped cream, a sprinkle of crushed graham crackers, and (optional but beautiful) a lime wedge and sprig of mint. Serve immediately with a straw and a spoon — because yes, you might want to scoop the whipped cream!

What to Serve With a Key Lime Pie Mojito

This cocktail shines on its own, but it also pairs beautifully with a range of light bites and tropical dishes. Here are some pairing ideas:

• Shrimp ceviche or fish tacos with lime crema for a zesty match
• Grilled pineapple skewers or tropical fruit salad for a sweet and tangy contrast
• Jerk chicken sliders for a spicy-savory pairing
• Mini crab cakes or coconut shrimp for elegant party bites
• Key lime pie bars if you want to go all in on the theme!

Tips for Success

• Use fresh ingredients: Freshly squeezed lime juice and vibrant mint make all the difference.
• Balance is key: Adjust the lime juice or condensed milk to your taste for that perfect sweet-tart harmony.
• Chill everything: Cold ingredients help the drink stay smooth and refreshing. You can even chill your glasses ahead of time!
• Shake well: That sweetened condensed milk needs to emulsify with the lime and rum — don’t skip this step!
• Layer your garnishes: Whipped cream first, then graham cracker crumble, then fresh mint and lime. This adds texture and a stunning presentation.

Storing and Make-Ahead Tips

You can mix the mojito base (everything except the club soda and garnishes) and store it in the refrigerator for up to 2 days. When ready to serve, just give it a good shake or stir, pour it over fresh ice, and top with soda and garnishes. Avoid storing the fully assembled cocktail — the soda will lose its fizz, and the whipped cream won’t hold.

Frequently Asked Questions

Can I make this without alcohol?
Yes! Just skip the rum and add a little extra club soda or a splash of coconut water. It still tastes like a creamy lime dream.

Is it too sweet?
It depends on your palate. The sweetened condensed milk adds a rich sweetness, but it’s balanced by the tart lime juice. If you prefer it less sweet, reduce the amount of condensed milk or increase the lime juice slightly.

Can I batch this cocktail for a party?
Definitely. Multiply the ingredients to suit your crowd and prepare the base in a pitcher. Just add ice, soda, and garnishes right before serving to keep it fresh and fizzy.

Is this drink heavy like a milkshake?
Not at all! It’s creamy, yes, but still light and drinkable thanks to the lime and mint. It strikes a wonderful balance between indulgent and refreshing.
