Tropical Boozy Cocktail Cubes for Summer Drinks

One of the best things about these frozen cocktail cubes is how flexible they are. Serve them with plain club soda for a crisp, bubbly drink, or use flavored sparkling water if you want an extra layer of taste. As the cubes melt, the drink gradually becomes sweeter and more tropical, creating a refreshing cocktail that changes with every sip.

For the photos, sparkling water was used so the melting cubes could be seen clearly in the glass. You can use the same idea at home, or choose any liquid that complements pineapple, coconut, and rum. The finished drink looks especially pretty in stemless wine glasses, cocktail glasses, or tall Collins glasses.

If you enjoy tropical drinks, these pineapple coconut rum cubes are a simple way to bring vacation-style flavor to your glass without needing a long list of ingredients or special equipment.

Tropical Cocktail Booze Cubes Instructions:

Before you begin, gather all of the ingredients so the preparation process is quick and easy. You will need pineapple juice, coconut water, rum, and club soda or sparkling water for serving. A large pitcher or blender works well for mixing, but any container that holds more than 30 ounces will do.

Add the pineapple juice, coconut water, and rum to the pitcher. Stir or gently mix until everything is well combined. There is no need to blend aggressively; the goal is simply to make sure the flavors are evenly distributed before freezing.

Next, pour the cocktail mixture into a large ice cube tray. Depending on the size of your tray, you may have some mixture left over. If that happens, simply pour the extra into another ice cube tray or use it in a popsicle mold to make boozy frozen pops. You can also save the extra mixture and use it in another drink.

Because this recipe contains alcohol, the cubes may take longer to freeze than regular ice cubes. Place the tray in the freezer for at least 8 hours. For the best texture and easiest handling, freeze the cubes overnight. If you remove them too early, they may be soft, sticky, and difficult to release from the tray.

Once the tropical cocktail booze cubes are fully frozen, place 3 cubes into a glass and pour about 8 ounces of club soda or sparkling water over the top. The cubes will slowly melt into the bubbles, creating a chilled pineapple coconut rum cocktail. For faster melting, use room temperature sparkling water rather than very cold liquid.

Garnish each drink with fresh fruit if desired. Lemon wedges, lime wedges, or strawberries all work nicely and make the drink feel bright and summery. Serve immediately and enjoy as the cubes gradually flavor the glass.
