What is Sugar Free Vanilla Syrup Made Of?
Sugar free vanilla syrup is made of water, vanilla extract, salt, and erythritol.
This sweetener is not necessarily bad for you and can actually be considered a much healthier alternative. However, we still believe it is very important to consider the ingredients and their nutritional value.
Therefore, we advise you to use this sauce in moderation. Moreover, our recipe is keto-friendly. Erythritol contains only 0.2 grams of net carbs per teaspoon, making it a great option for a keto diet.

Best Sugar Free Vanilla Syrup Brands
If you're looking for convenience or are in a bit of a rush, we recommend Torani, Starbucks, and Monin as the best sugar free vanilla syrup brands. The carbs in these sauces are 0 grams of carbohydrates per pump or ½ tbsp.
These options for Starbucks sugar free vanilla syrup are super popular among people observing a low-carb or ketogenic diet. However, ultimately it would be cheaper and healthier to make it from scratch.

Sugar Free Vanilla Syrup Ingredients
The main ingredients needed to make our homemade Starbucks sugar free vanilla syrup include water, vanilla extract, salt, and erythritol.
Vanilla Extract
Vanilla extract uses are very diverse in drink-making and baking. Therefore, it is an important ingredient in any pantry. However, there are two main types of extract available, pure and imitation.
The pure extract is made with beans and alcohol. Meanwhile, imitation extract is made with synthetic flavouring. Our recipe will use the pure extract as it is of higher quality and possesses a deeper, more complex flavour.
Salt
We use salt to enhance the flavour of the sugar free vanilla syrup. Just a small amount of it can bring out the sweetness and complexity of the flavour profile.
Erythritol
Erythritol is a sweetener that we derive from natural sources such as corn or birch. It has a sweetness level that is similar to sugar but with zero calories. So, if you want to savour your favourite desserts guilt-free, erythritol is your best bet!
Furthermore, it is a popular choice for low-carb recipes as it doesn't have a strong aftertaste, nor does it cause digestive issues.

Alternatively, if you can't find erythritol, use ½ -1 teaspoon of powdered stevia or ¼ -½ cup of monk fruit sweetener. However, keep in mind that stevia has a slightly bitter aftertaste, which can be off-putting. Conversely, monk fruit is a good substitute, adding a slightly fruity aftertaste to your sugar free vanilla syrup. But it is relatively more expensive in comparison to the other options.
How to Make Sugar Free Vanilla Syrup
Start by combining water and erythritol in a saucepan over medium heat. Stir until the sweetener dissolves. Allow the glaze to simmer for 5-7 minutes or until the mixture thickens slightly.
Once it thickens, remove the saucepan from heat and stir in the extract and salt. Allow the fragrant glaze to cool down to room temperature. Finally, store the sugar free vanilla syrup in a bottle or jar in the refrigerator.
When stored properly in a clean, airtight container in the refrigerator, this sauce should last up to 1 month. However, ensure you sterilise jars or bottles first before filling them in. You can do this by washing and heating them in a preheated oven at 120 degrees Celsius for 10 minutes or until dry.

Uses of Sugar Free Vanilla Syrup
This aromatic sweetener is a versatile ingredient that you can utilise in a plethora of recipes. The taste profile is quite harmonious with most flavours. Feel free to experiment with different flavour profiles and your preferred level of sweetness.
