Ingredients You’ll Need
This recipe calls for a handful of simple, wholesome ingredients that come together beautifully to create a dessert packed with balanced flavors. Each component plays a key role, from adding tropical brightness to creamy coolness and a rich, boozy caramel finish.
- Whole fresh pineapple: The star ingredient, providing juicy sweetness and perfect grill marks for that smoky touch.
- Vanilla ice cream: Adds creamy coolness and a classic flavor that pairs marvelously with warm pineapple.
- Unsalted butter: Essential for creating a silky, rich caramel sauce without overpowering the natural sweetness.
- Dark brown sugar: Gives depth and molasses notes to the caramel sauce, enhancing the sweetness.
- Ground cinnamon: Adds a subtle warm spice that complements both the pineapple and caramel flavors.
- Coconut rum and dark rum: These spirits bring a vibrant island flair and a hint of complexity to the caramel sauce.
- Toasted coconut (optional): Perfect for adding texture and a nutty accent as a garnish.
How to Make Grilled Pineapple Sundaes with Coconut Rum Caramel Sauce Recipe
Step 1: Prepare the Coconut Rum Caramel Sauce
Start by melting the butter gently over low heat with dark brown sugar and cinnamon in a small saucepan until the sugar fully dissolves. This slow cooking lets the flavors marry, creating that irresistibly smooth caramel base just begging to be drizzled on your pineapple. Then, carefully stir in the coconut rum and dark rum. Allow the mixture to simmer for about three minutes to deepen the flavors and slightly thicken the sauce before setting it aside in a sealed container to cool until you’re ready to serve.
Step 2: Slice and Core the Pineapple
Lay your whole fresh pineapple on its side and slice it into roughly half-inch thick rounds—a thickness that’s ideal for grilling without losing juiciness. Using a sharp knife, cut around the edges carefully to remove the tough skin. Then, with an apple corer or a slender knife, remove the hard core from the center of each slice. This ensures every bite is tender and easy to enjoy.
Step 3: Grill the Pineapple
Place the pineapple slices onto a preheated grill and cook them for three to five minutes on each side. The goal here is to get those appealing grill marks and a slight caramelization of the pineapple’s natural sugars without making them mushy. The smoky aroma combined with the pineapple’s tropical sweetness will have you hooked just watching this step.
Step 4: Assemble Your Sundaes
Once grilled, transfer each pineapple slice into individual serving bowls or plates. Top generously with scoops of vanilla ice cream that will start to melt over the warm pineapple creating a luscious contrast. Finally, drizzle this with the decadent Coconut Rum Caramel Sauce and finish with a sprinkle of toasted coconut if you want that extra crunch and flavor pop.
How to Serve Grilled Pineapple Sundaes with Coconut Rum Caramel Sauce Recipe
Garnishes
To elevate these sundaes, toasted coconut flakes are a divine choice—adding a subtle crunch and nutty flavor that contrasts beautifully with the smooth caramel and soft ice cream. If you want to get adventurous, a sprinkle of chopped macadamia nuts or a few fresh mint leaves can introduce freshness and textural play that impress your guests.
Side Dishes
This dessert shines perfectly on its own but can also be paired with light sides like a coconut-lime sorbet for extra tropical vibes or a small serving of spiced rum cake to keep the theme going strong. Fresh berries can add a tangy burst, balancing the caramel’s richness beautifully.
Creative Ways to Present
For a stunning presentation, serve the pineapple rounds in hollowed-out pineapple bowls or on a rustic wooden board accompanied by ramekins of additional sauce. Layered into parfait glasses with additional caramel sauce and ice cream makes an elegant, multi-textured treat that looks almost too good to eat.
Make Ahead and Storage
Storing Leftovers
If you happen to have any leftover caramel sauce, keep it in an airtight container in the fridge for up to two weeks. Avoid storing leftover grilled pineapple for too long as it tends to become too soft, but if needed, it can be refrigerated for a day or two.
Freezing
The caramel sauce freezes well in portions inside ice cube trays or small containers, providing an easy way to have it ready on hand. However, avoid freezing grilled pineapple slices or sundaes with ice cream, as the texture will suffer once thawed.
Reheating
To refresh the caramel sauce after refrigeration or freezing, warm it gently on the stovetop or in the microwave, stirring often to restore its smooth consistency. For grilled pineapple, a quick reheating on the grill or in a hot pan for a minute or two can bring back some warmth and brightness.
FAQs
Can I use canned pineapple instead of fresh?
While canned pineapple can work in a pinch, fresh pineapple offers far superior texture and natural sweetness that makes this recipe truly shine, especially when grilled.
Is it possible to make this recipe alcohol-free?
Absolutely! You can skip the rums or substitute them with coconut extract or pineapple juice to maintain the tropical notes without alcohol.
Can I use ice cream flavors other than vanilla?
Definitely! Coconut, mango, or even rum raisin ice cream would add exciting twists that complement this dessert beautifully.
How long does the coconut rum caramel sauce last?
Stored properly in a sealed container in the refrigerator, the sauce stays fresh for up to two weeks, making it perfect for make-ahead entertaining.
What’s the best way to toast coconut for garnish?
Simply spread shredded coconut on a baking sheet and toast it in a 350°F oven for 5-7 minutes until golden brown, stirring occasionally to prevent burning.

Ingredients
Grilled Pineapple
- 1 whole fresh pineapple
Ice Cream
- 2 cups vanilla ice cream
Coconut Rum Caramel Sauce
- 1/4 cup unsalted butter
- 1 cup dark brown sugar
- 1/2 teaspoon ground cinnamon
- 1/4 cup coconut rum
- 1/4 cup dark rum
Garnish (Optional)
- Toasted coconut
Instructions
- Make the Coconut Rum Caramel Sauce: In a small saucepan, combine the dark brown sugar, unsalted butter, and ground cinnamon. Cook over low heat, stirring occasionally, until the sugar fully dissolves and the mixture is smooth.
- Add the Rums: Carefully pour in the coconut rum and dark rum, stirring continuously to combine. Allow the sauce to simmer gently for 3 minutes to meld the flavors and thicken slightly. Remove from heat and store in a sealed container in the refrigerator until ready to use.
- Prepare the Pineapple: Place the fresh pineapple on its side and slice into approximately 1/2-inch thick rounds. Using a sharp knife, carefully cut around the outer edge of each slice to remove the skin without breaking the pineapple rings.
- Remove the Core: Use an apple corer or a sharp knife to cut out the tough core from the center of each pineapple slice, creating a hollow ring.
- Grill the Pineapple: Preheat your grill to medium-high heat. Place the pineapple slices directly on the grill grates and cook for 3 to 5 minutes per side, until they have nice grill marks and are slightly caramelized and tender.
- Assemble the Sundaes: Place each grilled pineapple ring in a serving bowl. Top generously with a scoop of vanilla ice cream. Drizzle warm coconut rum caramel sauce over the top to add a luscious finish.
