This quick and easy caffeinated sugar-free milkshake is a terrific grab-and-go summer treat. Each milkshake is just 5.8g net carbs- so it's definitely a treat. Just put all the ingredients in a blender and give it a whirl!
One of my favorite drinks before going completely low-carb was a MooLatte. We didn't go to Dairy Queen often, but when we did, I liked to get a MooLatte so I could have my ice cream in the car while driving without making a mess.
I'm also a lover of all things coffee. This sugar-free coffee milkshake is my spin on a coffee MooLatte drink. It's certainly not as healthy as low-carb smoothies, but it's a nice alternative to keto coffee for summer.
This milkshake also kind of resembles a frappuccino. No matter what you call it, this is an ice-cold caffeinated delight!
Ingredients Needed For A Sugar-Free Milkshake
This is such a simple recipe that you don't need very many ingredients. Here is a little more information about what I used.
This is my favorite part of the milkshake. Use finely-ground espresso powder to give this the coffee taste (and caffeine kick!).
The best replacement for espresso powder is going to be coffee ice cubes. You make them by brewing strong coffee and then pouring the coffee into an ice cube tray. Then, use these frozen coffee cubes in your milkshake.
I used 15 drops of Stevia. You can use your favorite sugar-free sweetener in this milkshake. Just make sure you use about two tablespoons. You will need to use either a granular or liquid sweetener!

The ice is what gives it a delightful and thick texture. Don't skip it!
Low-Carb Vanilla Ice Cream
If you want to make your own keto-friendly vanilla ice cream, I have an easy ice cream recipe.
You can also buy keto-friendly ice cream from the grocery store. Just make sure it is low in carbs.
Use unsweetened almond milk. I prefer to use plain almond milk, but you can use vanilla flavor if you like it.
This is completely optional. I like to add some cocoa powder because it turns my milkshake into a mocha.
Please note: Check out the recipe card at the bottom for a full list of ingredients used to make this low-carb recipe.
- Enjoy your milkshake immediately. It will melt and the texture will change, so drink it up as soon as you make it.
- To slow down how fast your milk shake will melt, store your glass in the freezer.
- If you want to make your shake thicker, use more ice cream and ice.
- To make your shake thinner, add more almond milk.
How To Make A Sugar-Free Milkshake With Coffee
This recipe makes two sugar-free milkshakes. So, if you want to make just one for yourself, I suggest cutting the ingredient amounts in half.
Blend Everything In A Blender
There really isn't a secret order to add things to your blender. Just add all the ingredients to the blender and pulse until it is nice and creamy.
That's really how easy it is! If you have a NutriBullet, you can drink your milkshake right in the glass you blended it in. It's so handy!
What To Serve With A Sugar-Free Milkshake
This milkshake is the perfect post-workout snack to re-energize you. It's also incredibly refreshing on a hot day!
For a post-workout snack, you'll want to munch on something high in protein (to repair the muscles you just worked). In that case, I like to eat a keto granola bar. It's high in fiber and protein and keeps me full until my next meal.
I also really enjoy dipping some keto fries into my milkshake. It's the ultimate way to indulge in both sweet and salty cravings.
If your chocolate cravings are going through the roof, then these peanut chocolate clusters, along with my mocha milkshake, are sure to do the trick.
Talk about a chocolate overload. Yum!
Frequently Asked Questions About Coffee Milkshakes
Before I get to the printable recipe card, here are some common questions people often ask about sugar-free milkshakes. If you don't see your question in this list, please leave it in the comments.
What do I do if my blender won't cut the ice up very well?
If your blender doesn't do a very good job cutting through ice, you'll want to use crushed ice. If your refrigerator doesn't have an ice-crushing mode, you can always go old-school and place some ice in a resealable plastic bag and use a rolling pin to crush it.
What is the best blender for cutting ice?
If you think you are going to be making lots of shakes and smoothies, I suggest investing in a professional blender like a Ninja or a Vitamix. They chop up ice into smooth drinks in no time at all - and will last you for years too.
If you don't think you'll get that much use out of it, then I suggest getting a NutriBullet. It's strong and powerful and can make just one shake at a time.
What are some low-carb things I can add on top of my sugar-free milkshake?
This is the fun part! Remember, every time you add something to your shake, you are possibly increasing how many carbs it has.
I like to top my shake with some whipped cream. You can also drizzle it with sugar-free chocolate syrup.
I've also seen people add unsweetened coconut flakes on top or some slices of fresh fruit.
What are some other flavors of milkshakes I can make?
There are so many options! Add some peanut butter for a peanut butter cup milkshake. Or, use almond butter and coconut flakes to create a shake that tastes like an Almond Joy.
If you create a fun flavor, let me know - I'd love to hear what you made!
