Sugar-Free Condensed Milk: Just 3 Ingredients! (Easy & Economical)

3. Check the Thickness

As the water evaporates, the liquid will turn a light cream color and begin to thicken. You will know it is ready when the liquid coats the back of your spoon or falls off the spatula in thick, heavy ribbons.

💡 Pro-Tip: Don’t let it get too thick on the stove! Condensed milk thickens up significantly as it cools down in the refrigerator. If it looks like a thick, pourable syrup, it’s time to remove it from the heat.

4. Cool and Store

Remove the pan from the heat and stir in the vanilla extract and tiny pinch of salt if using. Allow the mixture to cool completely at room temperature for about 20 minutes. Pour the smooth syrup into clean glass jars, seal tightly, and store in the refrigerator.
