I found a new way to make my favorite Watermelon Splash cocktail that is even better than my previous version (you can check out my Watermelon Pineapple Splash here). This one is a little fruitier and contains less sugar than the original version.

I also found a new sparkling water that is now my go-to whenever I want something bubbly, cool and refreshing – Bai Bubbles! I’m not being paid to say that I just love all the flavors and, even better, getting it without all the calories. My favorite flavors are grapefruit, blood orange and, of course, pineapple. You can still use soda in your version but it really is just as delicious, actually more so, with the Bai Bubbles.

To create this refreshing cocktail all you need is a blender, chunks of watermelon and fresh pineapple, some rum or vodka and several cans of Bai Bubbles. That’s it! Just blend up the watermelon and pineapple with either rum or vodka then pour into your favorite glasses. I used my stemless wine glasses and they worked perfectly. Add the sparkling water and garnish with either a watermelon wedge, lemon slice or pineapple slice or go for it and garnish with all three!

It’s deliciously thick, kind of a cross between a regular cocktail and a slushie, and perfect to sip with or without a straw. Now, sit back, relax and take a sip. Don’t you feel like you just got cooler? Can’t you feel the island breezes? OK, maybe I went a little far with that one but it really does have the all the tropical flavors of summer in a glass. It’s perfect for two or as a punch for your next picnic or BBQ. So what are you waiting for, it’s 5 o’clock somewhere, so go blend some up right now! I promise you’ll love it!
