Keto Spiked Root Beer Float

Low Carb / Keto / Gluten Free

Now, it may not come to anyone's surprise, but I really enjoy drinking alcoholic beverages. I mean, I am 23-years-old after all. Initially, that was one of the reasons that I started keto – it gave me the option to still enjoy nights out with friends drinking alcohol and also lose weight!

In the beginning, I stuck to my guns. I would drink either gin or vodka with soda and lime. If I was going to drink a shot, it would be either whiskey or more vodka (as noted in a previous post, you unfortunately have to avoid Jagermeister at 10 carbs/ounce).

One day, I was browsing the Reddit Keto group on Facebook and came across quite a few people who were enjoying their diet sodas with a splash of cream in them. I was a bit skeptical. It seemed a little weird.

I splashed a bit in my Diet Dr. Pepper and took a drink. OH MY GOSH. So delicious. It was kind of like a root beer float, only with Dr. Pepper. Perfectly creamy and such a great treat.

I took this a step further when I added alcohol…

Yes, a low carb and keto-friendly root beer float. I used The Kraken spiced rum for this recipe!

As always, remember to be responsible when drinking. Especially because it’s VERY easy to get drunk on a keto, low carb diet. Lack of carbs = total lush. Even you big guys, be careful!

    I know you wrote this years ago, but I found something you might want to try if you are still doing this. Today I found Bai Rioja Root Beer. No sugar, no artificial sweetheners. 10 grams of carbs from erythitol. Still not perfect but a lot better tasting than the diet stuff. Should mix incredibly well.

    Thank you! Thank you! Thank you!

    I love Kraken! And I’ve been on the keto diet for a month now and summer had become dull and tasteless (Root beer floats are a staple for summertime) until this recipe came along. I use plain whipping cream to get extra froth on top. I love it!

    Now, when you list four ingredients, including ice, and say to put “both ingredients into martini shaker with ice”, which two are you referring to, and are we talking about more ice?

    Just giving you a hard time, the cream in diet root beer move is the bomb. Props.

      Haha, isn’t it awesome though? I feel dumb that I had to make a “recipe” for it, but people like recipes, no matter how simple.

    Spiced rum is full of sugar. Might want to pick something else.

      My Kraken Spiced Rum has 0g of sugar and carbs.
