Understanding Sweetened Condensed Milk and Its Uses
Before diving into the process of making slow cooker sweetened condensed milk, it’s helpful to understand what sweetened condensed milk is and how it’s typically used in cooking and baking.
What Is Sweetened Condensed Milk?
Sweetened condensed milk is a thick, sweet dairy product made by removing most of the water from cow’s milk and adding sugar. The result is a creamy, viscous liquid with a rich, caramel-like flavor. It’s a common ingredient in desserts such as key lime pie, fudge, and caramel sauces. Its long shelf life and sweet, concentrated flavor make it a pantry staple for many bakers.
Common Uses in Recipes
- Caramel and Dulce de Leche: Using slow cooker methods, you can turn sweetened condensed milk into deep, luscious caramel or dulce de leche.
- Frostings and Fillings: It’s used as a base for creamy frostings, cheesecakes, and no-bake desserts.
- Cookies and Bars: Many recipes incorporate condensed milk for moisture and sweetness.
- Beverages: It can be used to sweeten hot beverages like Thai iced tea or coffee.

Why Use a Slow Cooker to Make Sweetened Condensed Milk?
The traditional way to make caramel or dulce de leche involves boiling a sealed can of sweetened condensed milk, but this method carries risks such as can rupture, burns, or uneven cooking. Using a slow cooker offers several advantages:
- Safety: No need to boil cans, reducing the risk of explosions or leaks.
- Ease: Set it and forget it—minimal monitoring needed.
- Uniform Heating: Slow cooker provides gentle, even heat, resulting in consistent caramelization.
- Convenience: Perfect for busy schedules or large batches.

How to Make Slow Cooker Sweetened Condensed Milk
Transforming sweetened condensed milk into caramel or dulce de leche in a slow cooker is straightforward. Here’s a step-by-step guide:
Ingredients Needed
- 1 can (14 oz or 400 g) of sweetened condensed milk
- Optional flavorings (vanilla extract, sea salt, etc.)
Equipment Required
- Slow cooker (preferably a large one)
- Baking or ramekin dish (if you want to prevent direct contact)
- Aluminum foil or lid
- Tongs or oven mitts
- Storage containers
Step-by-Step Process
1. Prepare the Can or Container:
- Option 1: Use the unopened can of sweetened condensed milk. This is the most traditional method.
- Option 2: Transfer the condensed milk to a heatproof, oven-safe dish or ramekin to avoid contact with water and prevent can corrosion or contamination.
2. Set Up the Slow Cooker:
- Fill the slow cooker with hot water until it reaches about halfway up the side of the can or dish containing the condensed milk.
- Ensure the water is hot but not boiling before placing the can or dish inside.
3. Cooking Time:
- For a rich, caramelized dulce de leche, cook for approximately 4-6 hours.
- For a lighter, more milk-like consistency, cook for 2-3 hours.
- The longer the cooking time, the darker and thicker the final product will be.
4. Monitoring:
- Check periodically to ensure water levels remain consistent, adding hot water if necessary.
- Avoid opening the lid frequently, as this affects the cooking process.
5. Cooling and Storage:
- Once the desired caramelization is achieved, carefully remove the can or dish using tongs or oven mitts.
- Allow it to cool before opening the can or transferring to storage containers.
- Store in an airtight container in the refrigerator for up to 2 weeks.
