Sometimes at the end of a meal you just want a dessert . . . that you can drink. Enter the key lime pie martini. This recipe, which mimics the flavors of a key lime pie, is delicious, smooth, and perfect when you are looking for a dessert cocktail.

Key Lime Martini Ingredients

  • Vanilla vodka: There are several brands that make vanilla vodka and it has just a slight vanilla flavor that adds so much to recipes. Use it again in my White Christmas Martini.
  • Citrus vodka: Look for a citrus or lemon vodka.
  • Key lime juice: You can’t make anything key lime flavored without key lime juice. This is different from regular lime juice and you can use it again in my key lime pie or key lime cheesecake.
  • Cream of coconut: This is coconut milk that is sweetened and thicker than regular coconut milk. It adds a little flavor and creaminess to the martini. I like using the Coco Lopez brand and you can find it in the international food aisle of your grocery store. I love it in my Coconut Margarita too!
  • Heavy whipping cream: It will give this martini recipe the perfect decadent taste and creaminess you are looking for. If you can’t find heavy whipping cream, use half and half (half heavy cream and half whole milk) or milk, just know your cocktail won’t be as thick and creamy.

How to Make a Key Lime Martini

This recipe is as simple as adding everything to a cocktail shaker. I start with ice, add the remaining ingredients, and then I shake until the shaker feels cold. Finally, strain it into a martini glass.

How To Serve

I love serving these in a martini glass with a simple lime slice. Often in restaurants you will see this cocktail served with a rim of crushed graham crackers. That works great as well! To do that, you will want to crush the graham crackers really fine. You could do that with a rolling pin on a ziplock bag, but you will find you can get them much more fine if you run them through a food processor.

To do the graham cracker rim, put a little bit of corn syrup on a plate and gently run the rim of the glass through it. Be careful not to get too much syrup on the rim. then dip the rim of the glass in the graham cracker crumbs. Add the martini and enjoy!
