This Watermelon Smoothie is the most refreshing summer beverage you will ever try. And, yes, it really is low carb and keto!
I spent many years working at Friendly's as a waitress. From when I was 17 off and on until I got married at 21. By the time I quit right before my wedding and college graduation, I knew what my menu favorites were. My favorite beverage was the Frozen Watermelon Slammer. It is made with watermelon sherbet and sprite. I've been craving one the past few years and I'm thrilled to now have a low carb and sugar-free watermelon smoothie alternative.
In this free 5-day email series learn all my tips for incorporating a low-carb lifestyle into the life of your family.
My mom hates anything watermelon flavored (she does love real watermelon) but I love it. I also love anything cotton candy flavored and my favorite Italian Ice as a kid was banana. I remember getting it from the Italian Ice truck during summer camp. It was bright yellow and tasted like the bananas in Runts candy. I might be the only one in the world with that as their favorite. What is your favorite Italian ice or popsicle flavor? Tell me in the comments, I'd love to hear!
When I found out that Lorann flavoring oils came in watermelon it made my day. (They do also come in cotton candy, banana, and a hundred other flavors). I can buy these at a local candy making store but they are also sold on Amazon. There are a few sellers that let you pick 12 different flavors for $15. I use the cinnamon oil in my Red Hot Gummies and the orange oil in my Creamsicle Gummies.
Ingredients in the Watermelon Smoothie: sweetener, half and half or heavy cream, lemon-lime seltzer, watermelon flavoring oil, lemon extract, vanilla extract, ice cubes, xantham gum (optional, keeps the drink from separating)
For another refreshing summer beverage, try my Sugar Free Lemonade, Keto Berry Smoothie, or Keto Pina Colada!
Make this for the kids? Add in some real watermelon. Check out How to Pick Watermelon here.

Do you think you could make this somehow with the True Lemon watermelon flavor?
Taryn says
Good idea! I'm not sure how many packets but I think it would work.
Angelique says
I really enjoyed reading about your fav flavors. My favorite memory was getting the banana or pistachio mini gelato cones from this Italian restaurant in Germany (where I grew up) that had a great little gelato stand in the front of the restaurant. mmmm I would love to recreate that keto someday. Now in TX this recipe looks perfect for our summer that lasts for over half the year.
Angelique says
Oh & I forgot to ask. Do you think this would be good to make into an alcoholic drink?
Taryn says
Sure. I'd use vodka since it is mild flavored.

I too was a fan of the Watermelon cooler at Friendly's, except I always ordered with water, I didn't like the fizz. I can't wait to try this!!!
