Making homemade dulce de leche is simpler than it looks. With just one ingredient and a little time, a sealed can of sweetened condensed milk becomes a rich, silky caramel sauce. Gently simmering the can yields a deep golden spread that far surpasses store-bought versions. It’s perfect for drizzling over ice cream, filling cookies, or spooning onto fruit—this straightforward method is reliably delicious.
One-Ingredient Dulce de Leche from Sweetened Condensed Milk
This is one of the easiest recipes you can make at home. The secret isn’t only the single ingredient but the method: simmering the factory-sealed can in water prevents scorching and produces a smooth, evenly caramelized dulce de leche with no stirring required. Because the can stays sealed during cooking, the finished dulce de leche is shelf-stable until opened, making it convenient to batch-cook and store in the pantry for weeks.
Simmering a few cans at once is a great way to have dulce de leche on hand for gifts, quick desserts, or last-minute baking. Once opened, transfer the dulce de leche to an airtight container and refrigerate.
Glue Removal Tip
Remove the paper label and any adhesive before cooking. If the label remains, the glue can dissolve into the water and stick to your pot. Use a safe adhesive remover or soak the can in warm, soapy water to loosen the label. In my experience, generic cans sometimes have tackier glue than branded cans, so check carefully.
Dulce de Leche Recipe
Equipment
-
Kitchen Scale (optional)
Ingredients
- 14 ounces sweetened condensed milk (1 can)*
Instructions
-
Remove the paper label and any remaining glue from the can.14 ounces sweetened condensed milk
-
Leaving the can sealed, place it upright or on its side in a medium pot. Pour in enough water to keep at least 2 inches of water covering the can throughout cooking.
-
Bring the water to a gentle simmer, then reduce the heat so the water stays at a low simmer. Cook for 3 hours, topping up the water as needed to keep the can submerged.
-
Carefully lift the can from the water and let it cool completely before opening. Opening while hot will cause the dulce de leche to spray out.
Notes
Tips:
- If using an aluminum pot, add a splash of white vinegar or lemon juice to the water to minimize scale build-up.
- Avoid cans with pull-tab openers; cans that require a can opener are less likely to deform or burst during cooking.
- Keep at least 2 inches of water above the can at all times to prevent overheating. Check every 20–30 minutes and add water as needed.
- Placing the can on its side can reduce rattling while the water simmers.
- Always let the can cool fully before opening to avoid splattering hot caramel.
- If the dulce de leche appears grainy after opening, whisk vigorously or blend briefly to smooth it out.
- For extra flavor, stir in a pinch of flaky sea salt, a teaspoon of vanilla paste, or a splash of dark rum after opening.
- Once opened, transfer to a food-safe airtight container—do not store in the can.
Alternative Cooking Methods:
- Crockpot: Remove labels, place sealed cans on their side in a slow cooker, cover with at least 2 inches of hot water, and cook on LOW for 8–10 hours. Let cans cool completely in the water before removing and opening.
- Oven: Pour sweetened condensed milk into a pie dish, cover tightly with foil, place the dish in a water bath, and bake at 425°F for 90–105 minutes or until it reaches the desired color. Cool to room temperature before using.
Make-Ahead: Unopened, cooked cans can be stored at room temperature for up to 3 months.
Storage: After opening, refrigerate dulce de leche in an airtight container for up to 2 weeks or freeze for up to 3 months. Thaw in the refrigerator overnight. If chilled too firm, warm briefly in the microwave to soften before serving.

Customize Your Consistency
I usually cook cans for 3 hours for a thick, spreadable dulce de leche that works for most uses. For a thinner sauce, reduce the time; for a denser, fudgier consistency, cook longer. Use these guidelines:
| Cook Time | Color | Consistency | Use |
|---|---|---|---|
| 2 hours | light | saucy | drizzling over desserts |
| 3 hours | deep golden | ideal; spreadable | spreading and dipping |
| 4 hours | dark | fudgy | filling cookies, candy |
How to Make Dulce de Leche Step-by-Step
Submerge the Can: Remove the label and any glue from a 14-ounce can of sweetened condensed milk. Leave the can sealed and place it in a medium pot. Fill the pot with water so there are at least 2 inches of water above the can.
Simmer the Can: Bring the water to a simmer over medium-high heat, then lower to maintain a gentle simmer. Cook for about 3 hours, topping up the water as necessary to keep the can submerged. Checking every 20–30 minutes works well.
Cool and Open: Carefully remove the can from the water and allow it to cool completely before opening. Opening a hot can can cause the dulce de leche to burst out under pressure, so patience is essential.
How to Store, Freeze, and Reheat
An unopened, cooked can can be stored at room temperature for up to 3 months. After opening, transfer dulce de leche to an airtight container and refrigerate for up to 2 weeks or freeze for up to 3 months. Thaw in the refrigerator overnight. If chilled dulce de leche becomes too firm, warm it briefly in the microwave for 10–15 seconds to soften.
