Ingredients for St Thomas Banana Daiquiri
A handful of tropical staples blend into this island-inspired glass of paradise.
| Ingredient | Amount | Notes |
|---|---|---|
| Light Rum 🍹 | 4 oz | White or gold variety |
| Dark Rum 🍹 | 2 oz | Aged for depth |
| Ripe Banana 🍌 | 1 whole | Fresh or frozen |
| Fresh Lime Juice 🍋 | 1 ½ oz | About 2-3 limes |
| Simple Syrup 🍯 | 1 oz | 1:1 sugar-water ratio |
| Coconut Cream 🥥 | 1 oz | Full-fat for creaminess |
| Orange Liqueur 🍊 | ½ oz | Triple sec works too |
| Ice Cubes ❄️ | 1 ½ cups | Crushed or cubed |
| Fresh Mint Sprig 🌿 | 1 piece | For garnish |
| Lime Wedge 🍋 | 1 piece | For garnish |
The rum is key here. Light rum keeps it crisp while dark rum adds caramel depth—Bacardi and Captain Morgan are easy to find at any liquor store. Bananas should be spotty-ripe for natural sweetness (frozen ones work great too, and they’re already cold). For the coconut cream, Coco López is the classic choice, but any full-fat canned coconut milk works if you blend it well first.
No coconut cream? Heavy cream isn’t vegan, so swap in coconut milk beverage at half the amount for a lighter texture. Out of simple syrup? Agave nectar or maple syrup work perfectly—just adjust to taste. The orange liqueur is optional but adds that signature Caribbean brightness (skip it entirely if you prefer). Fresh lime is non-negotiable though—bottled just doesn’t compare.
This is best served immediately, but you can prep the base (without ice) up to 24 hours ahead. Shake before using. Leftover blended mix? Freeze in popsicle molds for a boozy treat that keeps 1 month.

Step-by-Step Instructions for St Thomas Banana Daiquiri
Here’s how I blend this tropical masterpiece with the perfect balance of rum and banana flavor.
Step 1: Muddle the Ripe Banana
Peel the ripe banana and slice it into ½-inch rounds. Add the slices to your blender first—this positions them closest to the blade for even puréeing. I like to break it up a bit with a spoon before blending to help the process along.
The banana should be soft and speckled, which means it’s at peak sweetness. If you’re using a frozen banana, let it thaw for 5-10 minutes so it blends smoothly without straining your machine. This step ensures a silky texture without chunks.
Step 2: Combine All Liquid Ingredients
Pour in the 4 oz light rum, 2 oz dark rum, 1.5 oz fresh lime juice, 1 oz simple syrup, 1 oz coconut cream, and 0.5 oz orange liqueur. The dark rum adds depth, while the light rum keeps it crisp and refreshing.
I always add the coconut cream last of the liquids—it’s thick and tends to stick to the measuring spoon. A quick rinse with a splash of the lime juice helps get every last drop. Stir briefly with a long spoon to start combining everything before blending.
Step 3: Add Ice and Blend to Smooth Perfection
Toss in the 1.5 cups ice cubes and secure the lid tightly. Blend on high for 20-30 seconds until completely smooth. You shouldn’t see any ice chunks—just a creamy, frothy mixture.
If it’s too thick, add a splash of cold water and blend for another 5 seconds. The texture should be like a thick milkshake, pourable but with body. Stop blending as soon as it reaches this consistency to avoid over-diluting with melted ice.
Step 4: Taste and Adjust
Pour a small amount into a glass and taste. The balance should be tropical and tangy with a hint of coconut. If it’s too tart, add a touch more simple syrup and blend briefly. If it needs more rum character, a splash of light rum will do the trick.
I find the orange liqueur really ties everything together, but if you want more citrus punch, a bit more fresh lime juice brightens it up. This is your chance to fine-tune the flavors to your preference.
Step 5: Serve and Garnish
Divide the daiquiri between two chilled glasses. The colder the glass, the longer your drink stays frosty and refreshing. I like to run the lime wedge around the rim before pouring for an extra citrus aroma.
Garnish each glass with the fresh mint sprig—give it a light slap between your palms to release its oils before placing it on top. This final touch adds a fresh, herbal note that complements the tropical flavors perfectly. Serve immediately with a straw for sipping.
Pro Tips For Making St Thomas Banana Daiquiri
- Freeze the Banana: Cut your ripe banana into coins and freeze for at least 2 hours before blending—this eliminates the need for ice and gives the daiquiri a creamier, frostier texture.
- Balance the Rums: Use a 2:1 ratio of light to dark rum, like 4 oz light and 2 oz dark, so the dark rum adds depth without overpowering the banana and lime.
- Strain It Smooth: After blending, strain through a fine-mesh sieve to remove any fibrous bits from the banana—sounds tedious, but it makes the texture silky.
- Sweeten in Stages: Start with half the simple syrup, taste, then add more as needed; over-sweetening drowns the banana flavor, and it’s easier to add than to fix.
Dietary Considerations for This Dish
Vegan-Friendly Swaps
This tropical treat is naturally vegan as written—no dairy or animal products here. The coconut cream replaces traditional cream beautifully, adding richness without compromising dietary needs. Even the simple syrup is plant-based. 🌱
Gluten-Free Naturally
All ingredients in this blend are gluten-free by default. Rum is distilled from sugarcane, not grains, and the other components contain no gluten. Just double-check your orange liqueur brand—most are safe, but some cheaper versions may have additives.
Sugar Considerations
To reduce sugar, cut the simple syrup by half and let the ripe banana’s natural sweetness shine. For a sugar-free version, swap in monk fruit sweetener—use ¾ oz to match the sweetness level. The lime juice balances the flavors perfectly.
Allergen Alerts
The only potential allergen here is coconut in the cream. For nut-free versions, skip the coconut cream entirely and use oat milk for creaminess—though the texture will be lighter. Always check rum labels for hidden allergens if you have severe sensitivities. 💡
Low-Calorie Option
For a lighter version, reduce the coconut cream to ½ oz and use 1 cup ice instead of 1.5 cups. The result will be less creamy but still flavorful. A frozen banana adds thickness without extra calories—just blend it first with a splash of water.
Alcohol-Free Adaptation
Replace the rum with coconut water and add ½ tsp vanilla extract for depth. The orange liqueur can be swapped for orange juice. This creates a delicious mocktail that still captures the tropical essence, perfect for designated drivers or dry days.

Frequently Asked Questions
Can I use a frozen banana instead of fresh?
A frozen banana works perfectly and creates an even frosty texture. Just let it thaw for 5-10 minutes first so it blends smoothly without straining your machine.
What if I don’t have coconut cream?
Substitute coconut milk beverage at half the amount for a lighter texture. For richness, heavy cream works but isn’t vegan. Blend well to avoid separation.
How can I make this less sweet?
Reduce the simple syrup by half and rely on the banana’s natural sweetness. For zero sugar, use ¾ oz monk fruit sweetener instead. The lime balances it perfectly.
Can I prep this ahead for a party?
Mix all ingredients except ice up to 24 hours ahead. Store in the fridge, then blend with ice just before serving. Shake before using.
