Instructions
Step 1: Combine the Milk and Butter
Pour the milk into a medium-sized, heavy-bottomed saucepan.
Add the butter and place the saucepan over low to medium-low heat.
Stir gently until the butter has completely melted into the milk.
Do not allow the mixture to boil aggressively. Gentle heating helps prevent the milk from scorching.
Step 2: Reduce the Milk
Once the butter has melted, continue cooking the mixture over low heat.
Stir frequently, especially around the bottom and edges of the pan.
The goal is to slowly evaporate some of the water from the milk, leaving behind a thicker and creamier mixture.
This process can take approximately 20–30 minutes, depending on the size of your saucepan and the heat level.
Avoid turning the heat too high. Cooking too quickly can cause the milk to scorch or develop an unpleasant flavor.
Step 3: Add the Sweetener
Once the milk has reduced and become noticeably thicker, remove the saucepan from the heat.
Add your powdered sugar substitute.
Whisk thoroughly until the sweetener has completely dissolved and the mixture is smooth.
Using powdered sweetener helps prevent a gritty texture.
Step 4: Cool
Allow the condensed milk to cool at room temperature for several minutes.
Don’t worry if it seems slightly thinner than expected while hot. The mixture will continue to thicken as it cools.
For an even thicker consistency, refrigerate it for a few hours.
Step 5: Store
Transfer the cooled condensed milk to a clean, airtight glass container.
Keep refrigerated and use it within approximately 5–7 days, depending on the freshness of your ingredients and storage conditions.
Always use a clean spoon when removing portions from the container.
How to Get the Best Texture
The key to homemade condensed milk is patience.
Keep the heat low and allow the milk to reduce gradually. Rapid boiling can cause the milk to scorch and may create a grainy or unpleasant texture.
For the smoothest result:
- Use whole milk.
- Use a heavy-bottomed saucepan.
- Stir regularly.
- Avoid high heat.
- Use powdered sweetener.
- Allow the mixture to cool completely before judging its final thickness.
If Your Condensed Milk Is Too Thin
If the mixture isn’t as thick as you’d like, return it to the saucepan and cook it over low heat for a few additional minutes.
Stir continuously while it reduces.
Remember that the mixture will become thicker once refrigerated, so avoid reducing it too much while it’s still hot.
If Your Condensed Milk Is Too Thick
If your finished condensed milk becomes too thick, whisk in a small amount of warm milk until it reaches your desired consistency.
Add the milk gradually so you don’t accidentally make it too thin.

Recipe Variations

Important Note About “Sugar-Free”
Although this recipe contains no regular table sugar, the nutritional content depends on the type of milk and sweetener you use.
Also, not every sugar substitute behaves exactly like sugar when heated or refrigerated. Some sweeteners can crystallize or leave a cooling sensation.
For the smoothest texture, choose a powdered sweetener designed to dissolve easily.
Frequently Asked Questions
Can I use skim milk?
You can, but whole milk generally produces a richer and creamier result. Lower-fat milk may produce a thinner condensed milk.
Can I use regular powdered sugar?
Yes, but then the recipe will no longer be sugar-free.
Can I use liquid sweetener?
You can experiment with liquid sweeteners, but they may change the consistency. A powdered sweetener is generally easier to incorporate into this recipe.
Why is my condensed milk grainy?
The sweetener may not have dissolved completely, or the mixture may have been cooked at too high a temperature. Using powdered sweetener and gentle heat can help produce a smoother texture.
Does it thicken after cooling?
Yes. Homemade condensed milk usually becomes noticeably thicker as it cools and chills.
Storage
Store the finished condensed milk in an airtight container in the refrigerator.
For the best quality, use it within 5–7 days and discard it if you notice an unusual smell, appearance, or texture.
