Homemade Sweetened Condensed Milk Recipe

1. Combine milk and sugar in a medium saucepan over medium heat.
2. Stir constantly until the sugar fully dissolves (about 2–3 minutes).
3. Bring to a gentle simmer — do not boil. Reduce heat to low.
4. Simmer uncovered, stirring occasionally, for 30–40 minutes. The mixture should reduce by about half and thicken slightly. It will thicken more as it cools.
5. Remove from heat. Stir in butter and vanilla (if using) until smooth.
6. Let cool, then store in a glass jar or airtight container in the fridge for up to 1 week.
