This Keto Blueberry Moscow Mule Cocktail is perfect for summer sipping, and won’t kick you out of ketosis! Coming it at only 72 calories and 2g net carbs, this is going to be your new favorite keto cocktail!
When pondering my options for a blueberry themed summer cocktail to post this month, I almost passed this Keto Blueberry Moscow Mule concept by. Moscow Mules are typically considered more a winter drink, maybe because of the ginger. But my love of ginger and the Moscow mule cocktail in all it’s forms cannot be bound by season.
So I went for it and I promise you’ll be glad I did! As an added bonus, these are a gorgeous color, so you can forsake your usual copper mugs and serve it a glass tumbler to fully appreciate the experience!
To get the pretty color and blueberry flavor for these low carb Moscow Mules, I pureed fresh (you could also use frozen) blueberries with a little sweetener and water. Then I strained it through a fine strainer to get all of the seeds and skins out. It takes a couple of extra minutes to do it this way, but the results are worth it, and the blueberry juice can be stored in the refrigerator or even frozen until you need it.
I recommend making a big batch of the juice while blueberries are in season, and then you’ll have some available whenever the craving for this Keto Blueberry Moscow Mule strikes. The amount called for in this recipe makes enough for about 12 mules.
I used diet ginger beer for this Keto Blueberry Mule recipe but if you can’t get it, you can make the keto ginger syrup I use in these keto Minty Moscow Mules that I posted a couple of years ago. Just leave out the mint and pour in the blueberry juice and you’ll be very close to the flavors in this version.
I chose to garnish the rim of my Keto Blueberry Moscow Mules with a mix of cinnamon and granulated erythritol (I used Swerve) and it worked like a charm. The hint of cinnamon in each sip gave it a homey flavor, reminiscent of blueberry pie – but with a ginger kick. Hard to describe, awesome to experience.
I highly recommend the rim garnish if you can, but these Keto Blueberry Moscow Mules are still refreshing and delicious without it!

I know that diet ginger beer is not available. Do you think diet gingerale would work? I bet it does not have a big enough kick. I remember my first ginger beer was in the Caribbean and it was pretty potent. Thanks for all you do.
You can make my ginger syrup and that will boost the ginger flavor – it can be frozen and kept as ice cubes for future use!
