The rum is non-negotiable here. Havana Club or Bacardi Superior are classic choices—smooth, clean, and not too sweet. For the coconut cream, Coco López is the easiest (find it in the international aisle at most grocery stores), but full-fat canned coconut milk works too if you’re in a pinch. Bananas should be spotty ripe for maximum sweetness—freeze them first for that signature daiquiri thickness.
No white rum? Gold rum adds depth but goes heavier on the spice notes. Skip the simple syrup? Agave or honey at a 1:1 ratio works fine. If coconut cream isn’t your thing, half-and-half or condensed milk can sub in (but it won’t be dairy-free). Fresh lime is a must though—bottled just doesn’t cut it here (trust me on this one).
This keeps 1-2 days in the fridge, but it’s best fresh—blend and serve immediately. The banana might brown slightly, but a quick stir fixes that. Freeze leftovers in popsicle molds for a boozy treat later (or just make another batch).

Step-by-Step Instructions for St Thomas Banana Daiquiri
Here’s the method to blend this tropical treat to perfection every time.
Step 1: Prepare the Base Ingredients
Start by peeling the 2 whole Ripe Bananas and slicing them into chunks. I like to freeze the banana slices for 15-20 minutes before blending—this gives the daiquiri that signature creamy, milkshake-like texture.
Measure out the 4 oz White Rum, 1.5 oz Fresh Lime Juice, and 1 oz Simple Syrup and have them ready to go. Using chilled ingredients here keeps the drink refreshing and prevents it from getting watery too quickly.
Step 2: Blend the Tropical Foundation
Add the banana chunks, 4 oz White Rum, 1.5 oz Fresh Lime Juice, 1 oz Simple Syrup, and 2 oz Coconut Cream to your blender. The coconut cream adds that rich, island-inspired depth that makes this drink special.
Blend on high for 20-30 seconds until completely smooth. You shouldn’t see any banana chunks or separation in the mixture. If it looks too thick at this point, don’t worry—the crushed ice will help balance it out.
Step 3: Incorporate the Ice and Final Flavors
Add all 2 cups Crushed Ice to the blender along with the 0.5 tsp Vanilla Extract and 0.25 tsp Ground Cinnamon. The vanilla enhances the banana flavor while the cinnamon adds a warm, subtle spice that complements the tropical notes perfectly.
Blend again on high for 30-45 seconds until the mixture is thick and smooth, like a frozen milkshake. Stop and scrape down the sides once or twice if needed. You want it to be pourable but still have that spoonable thickness.
Step 4: Serve with Island Flair
Pour the daiquiri into two chilled glasses. The serving size is perfect for 2, so divide it evenly. For the finishing touch, garnish each glass with 2 slices Lime Wedges and 2 whole Fresh Mint Leaves.
The lime wedges add a fresh, citrusy aroma, while the mint brings a pop of color and a hint of brightness to each sip. Serve immediately with a straw for the full tropical experience.
Pro Tips For Making St Thomas Banana Daiquiri
- Freeze the Bananas: Toss your ripe bananas in the freezer for at least 2 hours before blending—they’ll thicken the daiquiri naturally and save you from adding ice that waters it down. I learned this the hard way after too many slushy, diluted drinks.
- Use Overripe Bananas: The blacker the peel, the sweeter the flesh—these will give your daiquiri a deeper flavor and reduce the need for extra simple syrup. Sounds weird, but it works.
- Shake the Coconut Cream: Give the coconut cream a good shake or stir before measuring, as it separates in the can. My first batch had a greasy layer on top because I skipped this—ruined the texture.
- Chill Everything: Refrigerate your rum, lime juice, and simple syrup for 30 minutes before blending. It keeps the drink cold without diluting it with ice, and the flavors actually taste cleaner.
Storing and Reheating Leftovers
Short-Term Chilling
If you have leftovers, pour the daiquiri into an airtight container and refrigerate for up to 24 hours. The flavors stay vibrant, but the texture softens as it warms. Give it a quick stir before serving over fresh crushed ice to restore that frosty consistency. ❄️
Freezing for Later
This blend freezes beautifully for up to 1 month. Pour into ice cube trays or small freezer-safe jars. Thaw in the fridge for 2-3 hours before re-blending with ½ cup crushed ice to revive the perfect texture.
Re-Blending Tips
After storing, the mixture may separate slightly. Simply add ¼ cup fresh lime juice or 1 oz coconut cream, then blend again for 20-30 seconds. This refreshes the flavors and brings back the creamy consistency.
Avoiding Ice Crystals
To prevent icy textures when storing, use freshly crushed ice in your initial blend. Store-bought bagged ice can introduce excess water. I always crush my own for the smoothest results.
Serving from Frozen
For a slushie-style treat, blend frozen daiquiri cubes with 2 oz white rum and ½ cup crushed ice. This creates a stronger, more concentrated version perfect for sipping by the pool. 💛

Frequently Asked Questions
Can I use dark rum instead of white?
Yes, but it changes the flavor profile. Dark rum adds deeper molasses notes, making the drink richer. For the classic St. Thomas taste, stick with white rum though.
Why freeze the bananas first?
Frozen bananas create that thick, creamy texture without watering down the drink. Fresh bananas work but result in a thinner consistency. Freeze for at least 15-20 minutes.
What if my daiquiri is too thick?
Add 1-2 oz of coconut milk or lime juice and blend again. The key is balance—you want it thick but still pourable.
Can I make this non-alcoholic?
Replace the rum with 4 oz of coconut water or pineapple juice. You’ll still get that tropical flavor, just without the kick.
