This tropical cocktail combines the tangy flavors of key lime pie, the creaminess of cheesecake, and the island vibes of a piña colada into one unforgettable frozen drink. The graham cracker rim and cream cheese addition transform a classic beach cocktail into a dessert-inspired indulgence you can sip.
I created this cocktail for my sister's tropical-themed birthday party last summer, and it quickly became the most requested drink at all our family gatherings. Even my mother-in-law who rarely drinks alcohol asks for one every time she visits!
Ingredients
- White rum: Provides the classic boozy foundation without competing with other flavors
- Key lime juice: Brings authentic tangy brightness that regular limes can't match
- Cream of coconut: Adds tropical sweetness and silky texture look for Coco López brand
- Pineapple juice: Contributes natural sweetness and tropical fruit flavor use 100% juice not from concentrate
- Heavy cream: Creates the milkshake-like consistency that mimics cheesecake richness
- Cream cheese: The secret ingredient that transforms this from a standard piña colada to a cheesecake experience
- Powdered sugar: Allows you to control sweetness while dissolving completely
- Ice: Chills and thickens the drink to perfect frosty consistency
Step-by-Step Instructions
- Prepare the Garnishes:
- Create the signature "pie crust" rim by wetting the edge of your glass with key lime juice. The juice acts as an adhesive for the graham cracker crumbs which should be finely crushed for the best adherence. This step not only looks impressive but adds texture and flavor with each sip.
- Blend the Cocktail:
- Combine all liquid ingredients with the cream cheese and ice in a high-powered blender. The order matters add the cream cheese first so it fully incorporates without clumping. Blend on high speed for at least 30 seconds until completely smooth with no visible cream cheese pieces. The texture should be thick but pourable similar to a milkshake.
- Assemble and Serve:
- Pour immediately after blending as the cocktail will begin separating if it sits too long. Fill the glass to about 1/4 inch below the rim to leave space for toppings. Add whipped cream in a decorative swirl and sprinkle with graham cracker crumbs for visual appeal and flavor reinforcement.

I discovered the magic of adding cream cheese while trying to use up leftovers from a cheesecake baking project. That happy accident completely transformed the drink giving it the perfect texture that reminds me of the creamy filling in my grandmother's key lime pie that she made every summer during our beach vacations.
Make-Ahead Tips
Prepare all ingredients except ice up to 4 hours in advance and store in the refrigerator. This cocktail preparation method allows the cream cheese to fully infuse with the tropical flavors creating an even more integrated taste profile. Simply add ice and blend when ready to serve. For parties consider preparing a large batch of the liquid mixture then blending individual portions with fresh ice as guests arrive.
Flavor Variations
The versatility of this cocktail base allows for numerous creative adaptations. Substitute the key lime juice with lemon for a lemon meringue pie version. Replace pineapple juice with strawberry puree for a strawberry cheesecake experience. Add a tablespoon of chocolate syrup and use chocolate graham crackers for the rim to create a chocolate key lime variation. My personal favorite twist is adding a half teaspoon of cinnamon to the mixture which adds warmth and complexity.
Serving Suggestions
While this cocktail stands beautifully on its own it pairs wonderfully with tropical desserts or as a dessert replacement itself. Serve in hurricane glasses for casual gatherings or in martini glasses for an elegant presentation. For a dramatic serving option freeze hollowed pineapple halves for 30 minutes and use them as natural cocktail vessels. The drink makes an excellent finale to a Caribbean inspired meal featuring jerk chicken coconut rice or grilled seafood.
