Ingredients
- 2 cups (480 ml) whole milk
- ⅔ cup (135 g) granulated sugar
- 2 tbsp unsalted butter
- 1 tsp vanilla extract (optional)
Instructions
- Combine milk and sugar
In a medium saucepan, whisk together the milk and sugar. - Simmer gently
Heat over medium-low until the mixture begins to steam.
Reduce heat to low and let it simmer gently, stirring occasionally.
Avoid boiling — it should stay at a slow simmer. - Reduce the mixture
Continue simmering for 30–40 minutes, until the liquid reduces by about half.
It should look slightly thickened but still pourable; it will thicken more as it cools. - Add butter and vanilla
Remove from heat and stir in the butter (for smoothness) and vanilla, if using. - Cool
Let it cool completely. It will thicken to the classic condensed-milk consistency.
Storage
- Refrigerate in an airtight jar for up to 1 week.
- Freeze for up to 3 months (thaw in the refrigerator).
Tips
- For a richer version: substitute ½ cup of the milk with heavy cream.
- For a dairy-free version: use full-fat coconut milk and follow the same steps.
