Ingredients for St Thomas Banana Daiquiri
A few tropical ingredients transform into this velvety frozen treat with ease.
| Ingredient | Amount | Notes |
|---|---|---|
| Ripe Bananas 🍌 | 2 whole | Frozen for best texture |
| White Rum 🍹 | 4 oz | Caribbean or St. Thomas preferred |
| Coconut Cream 🥥 | ½ cup | Full-fat for creaminess |
| Fresh Lime Juice 🍈 | 2 tbsp | Newly squeezed for tang |
| Agave Nectar 🍯 | 1 ½ tbsp | Adjust sweetness to taste |
| Ice Cubes ❄️ | 2 cups | Crushed or cubed |
| Vanilla Extract 🌿 | ½ tsp | Pure for best flavor |
| Ground Cinnamon 🌶️ | ¼ tsp | Optional for warmth |
| Pinch of Salt 🧂 | 1 pinch | Balances sweetness |
The bananas are key—use the ripest ones you can find (the heavily speckled kind). Trader Joe’s and Whole Foods always have good options, but any grocery store works. The rum makes a difference too—Cruzan or Captain Morgan are solid choices for that authentic Caribbean flavor. Frozen bananas blend smoother, so freeze yours overnight if they aren’t already.
No coconut cream? Full-fat coconut milk works, but it’ll be slightly thinner. Out of agave? Maple syrup or date syrup at the same amount. If you want extra richness, add a splash of coconut water (about 2 tbsp). The cinnamon is optional but adds a nice warmth—skip it if you prefer pure tropical flavor (I usually do).
This blend is best fresh but holds up for 1-2 hours in the freezer. Shake or stir before serving if it separates. Makes 2 large or 3 small daiquiris—scale as needed.

Step-by-Step Instructions for St Thomas Banana Daiquiri
Here’s the method. Straightforward, tested, works every time.
Step 1: Prepare and Freeze the Bananas
Peel the 2 whole Ripe Bananas and slice them into ½-inch thick rounds. Arrange the slices in a single layer on a parchment-lined tray. Freeze for at least 2 hours or until completely solid.
I always freeze the bananas first—this gives the daiquiri that perfect thick, creamy texture without needing to add extra ice. The slices should be hard and cold to the touch before blending. If you’re in a hurry, you can freeze them for 1 hour, but the texture won’t be quite as smooth.
Step 2: Combine Liquid Ingredients in Blender
In a high-powered blender, add the 4 oz White Rum, 0.5 cup Coconut Cream, 2 tbsp Fresh Lime Juice, 1.5 tbsp Agave Nectar, 0.5 tsp Vanilla Extract, 0.25 tsp Ground Cinnamon, and 1 pinch Pinch of Salt.
Pulse a few times to combine the liquids. I like to let this mixture sit for 1-2 minutes while the frozen bananas finish their final freeze. This gives the flavors a chance to meld before blending. The coconut cream should be fully incorporated—no white streaks remaining.
Step 3: Add Frozen Bananas and Ice
Add the frozen banana slices and 2 cups Ice Cubes to the blender. Secure the lid tightly. Start blending on low speed, then gradually increase to high. Use a tamper to push the mixture down toward the blades if your blender has one.
Blend for 30-45 seconds until completely smooth, stopping to scrape down the sides if needed. The mixture should be thick and creamy, like a milkshake. If it’s too thin, add a few more ice cubes and blend again. If it’s too thick, add a splash of rum or water to reach your desired consistency.
Step 4: Taste and Adjust
Pour a small amount into a glass and taste. The balance should be tropical and refreshing with a hint of warmth from the cinnamon. The lime should provide a bright contrast to the sweetness of the bananas and agave.
If you want it sweeter, add a little more agave nectar and blend again. If it needs more tang, squeeze in a bit more lime juice. I’ve found that the cinnamon and vanilla add depth, but they shouldn’t overpower the banana and coconut flavors. Serve immediately for the best texture.
Pro Tips For Making St Thomas Banana Daiquiri
- Chill Your Bananas: I learned this the hard way—using room temperature bananas makes the drink foamy and thin. Freeze ripe bananas for at least 2 hours before blending for a thick, creamy texture.
- Use Fresh Lime: Bottled lime juice just doesn’t cut it here. Freshly squeezed lime juice adds the bright, zesty kick that balances the sweetness of the banana and agave.
- Blend in Stages: Start with the liquids first—rum, coconut cream, and lime juice—then add the frozen banana and agave. This prevents the blender from getting stuck and guarantees a smooth, even consistency.
- Adjust Sweetness Last: Bananas vary in ripeness, so taste before adding all the agave. I often need less than the recipe calls for, especially if the bananas are extra sweet.
Essential Equipment for This Recipe
High-Powered Blender
A high-powered blender is non-negotiable for that ultra-smooth texture. I swear by my Vitamix 5200—it pulverizes frozen bananas and ice into a creamy dream in seconds. Budget pick: Ninja Professional works too, though you may need to scrape the sides more often. 💡
Precision Measuring Tools
Accurate measurements matter with cocktails. Use a jigger for the 4 oz rum and a liquid measuring cup for the 0.5 cup coconut cream. I keep a OXO Good Grips set in my drawer—durable and easy to read.
Freezer-Safe Prep Tools
For freezing bananas, a parchment-lined baking sheet prevents sticking. I use half-sheet pans from USA Pan—they’re sturdy and fit perfectly in my freezer. Once frozen, transfer slices to a ziplock bag for storage.
Serving Glassware
Chilled 12-oz daiquiri glasses enhance the experience. Pop them in the freezer for 10 minutes before serving. No special glasses? Mason jars work in a pinch and add rustic charm. The cold glass keeps your drink frosty longer.
Bar Essentials
A long-handled bar spoon helps stir and taste without spilling. I also keep a fine-mesh strainer handy for any stray ice chunks. For garnish, a microplane quickly zests lime or grates fresh nutmeg over the top.

Frequently Asked Questions
Can I use fresh bananas instead of frozen?
Fresh bananas will work but the texture won’t be as thick. Add 1 extra cup of ice to compensate. Frozen bananas create that perfect creamy consistency without watering down the flavor.
What type of rum works best?
For authentic St. Thomas flavor, use a Caribbean white rum like Cruzan. Darker rums add depth but may overpower the banana. Always choose a quality rum—it makes a noticeable difference.
How do I make this less sweet?
Reduce the agave nectar to 1 tbsp or omit it entirely. The natural sweetness of ripe bananas and coconut cream may be enough. Balance with an extra 1 tbsp lime juice for tang.
Can I prepare this ahead of time?
Best served immediately, but you can store in the freezer for 1-2 hours. Stir well before serving as separation may occur. Avoid storing longer as it can develop ice crystals.
