Key Lime Pie Mojito Cocktail Recipe

There’s just something about a Key Lime Pie Mojito that makes summer feel like it’s right here, even if it’s not. That mix of fresh lime, mint, and sweetness? It’s basically a tropical breeze in a glass.

Honestly, I can’t get enough of how this cocktail brings together the creamy tang of key lime pie and all the refreshing kick of a classic mojito.

You can make this drink with simple ingredients and a few easy steps—nothing fancy here. I’ll go through the equipment, the ingredients, and each step so you end up with a cocktail that feels both familiar and kind of new.

Key Lime Pie Mojito Cocktail Recipe

I usually make this when I want something cool, creamy, and citrusy. Key limes bring a tart punch, the mint keeps things fresh, and rum smooths it all out.

Crushed graham crackers and a splash of cream give it that pie-like twist, making it both refreshing and just a little bit rich.

Equipment

• Cocktail shaker for mixing everything together
• Muddler for pressing the mint leaves and releasing their oils
• Jigger or a small measuring cup for the rum, juice, and syrup
• Bar spoon for gentle stirring
• Fine strainer to catch mint bits and ice shards
• Short glass or rocks glass for serving
• Small plate or bowl for the crushed graham crackers to rim the glass
• Citrus juicer for squeezing fresh key limes
• Ice scoop or a spoon to handle the crushed ice

I like to have all my tools nearby before I start—makes things smoother. A chilled glass keeps the drink cold longer, and honestly, it just feels better.

Ingredients

• 2 oz white rum
• 1 oz fresh key lime juice
• ½ oz simple syrup
• 6–8 fresh mint leaves
• 1 tbsp heavy cream
• 2 tbsp crushed graham crackers for rimming
• Crushed ice or ice cubes as needed
• Splash of club soda
• Key lime wheel and mint sprig for garnish

I always go for fresh key limes—they give a sharper, brighter flavor than the regular ones. Heavy cream softens the acidity, and that graham cracker rim? It’s like a little nod to the pie crust.

Instructions

• Rim your glass with lime juice, then dip it into the crushed graham crackers.
• In a shaker, muddle the mint leaves gently with simple syrup and lime juice.
• Pour in the white rum, add heavy cream, and toss in a handful of crushed ice.
• Shake it up for about 10 seconds—just until it’s chilled and a bit frothy.
• Strain the drink into your prepared glass filled with ice cubes.
• Add a splash of club soda on top.
• Garnish with a mint sprig and a thin key lime wheel.

I shake just enough to mix the cream in without turning it too thick. If it looks separated, I’ll give it a quick stir before serving.

Notes

I really do prefer fresh key lime juice—it just pops more. If you can’t find key limes, regular lime juice will do, though the flavor’s a little less bold.

Want it lighter? Skip the cream and pour in more club soda. If you like it sweeter, add a touch more simple syrup.

The graham cracker rim softens fast, so I usually rim the glass right before I pour. And when I want a slushier drink, I use crushed ice instead of cubes.

Tasting Notes

Right away, the mint flavor jumps out at me. It’s fresh and cool, giving the drink a crisp start.

The mint actually keeps the sweetness in check, so every sip stays light.

Then the lime kicks in. Tart, but not too sharp—it adds this bright citrus edge that honestly reminds me a bit of a classic mojito.

The lime juice slices through the creaminess of the pie-inspired mix and keeps things lively.

A graham cracker rim brings a soft crunch, plus just a hint of sweetness. It makes the drink feel like dessert, but without weighing it down.

I pick up a little rum in the background. It’s smooth, blending right in with the lime and mint.

The rum leaves a warm finish that lingers, but not in an overpowering way.

That cream or condensed milk gives the whole thing a silky texture. It softens the acidity and ties everything together.

Flavor balance:

• Sweetness: mild and creamy
• Sourness: moderate from lime
• Mintiness: cool and refreshing
• Texture: smooth with a light froth

Every sip feels clean and refreshing. There’s this mix of sweet, tart, and minty notes that just stay balanced all the way through.
