Sweetener for Keto Vanilla Milkshake

To add a little bit of sweetness to the keto vanilla milkshake, you can add your favorite sweetener. In this recipe, I use Lakanto brand of sweetener. I opted for the powdered form to make sure all of the sweetener gets dissolved to create a smooth, creamy vanilla shake. You can substitute with your favorite sweetener as long as it measures cup for cup with sugar.

Milk Options

Although this sugar-free milkshake can be made entirely from heavy whipping cream, I like to thin it out with a nut milk. This will help decrease the calories consumed. My favorite nut milk is macadamia nut milk. It is creamy and contains very low carbs compared to other nut milks. If you can’t source macadamia nut milk, you can use any nut milk as a replacement. Try coconut milk, almond milk, hemp milk, pili nut milk or cashew milk when making your keto vanilla shake.

Keto Protein Powder

If you want to add a little protein to your keto vanilla smoothie, I highly recommend the whey protein powder by Perfect Keto. This protein powder is made with clean ingredients and from grass-fed cows.

Adding protein powder to a milkshake is a great way to add a little extra protein to help keep you full. It’s a good way to get protein in my kids’ diet without them knowing. My kids love vanilla shakes in the summer time and this is one tasty treat I don’t mind making for them – especially if it has a little extra protein. They also love it with a straw and cherry on top!

Absolutely! While this recipe calls for unsweetened macadamia nut milk, you can substitute it with any unsweetened nut milk like almond or coconut milk, or even unsweetened soy milk.

What can I substitute for powdered monkfruit or erythritol?

If you prefer a different sweetener, you could use stevia or allulose, but keep in mind that the sweetness level may vary, so start with a smaller amount and adjust to taste!
