No, unopened store-bought dulce de leche doesn’t require refrigeration, but once opened or homemade, it must be refrigerated to maintain safety and quality.
Does Dulce De Leche Need To Be Refrigerated?
Let’s get right to it – the answer depends on whether you’re dealing with store-bought, unopened dulce de leche or an opened can (store-bought or homemade). Dulce de leche is a gloriously thick, sweet, caramel-like treat used in baking, desserts, and even just enjoyed on its own. It’s made by slowly simmering milk and sugar, and the result is pure deliciousness. But, like many foods, how you store this treat plays a major role in keeping it safe to eat and maximizing its shelf life.
Store-Bought, Unopened Dulce De Leche
Store-bought dulce de leche typically comes in cans. While unopened, these cans are shelf-stable, meaning you don’t need to refrigerate them. A cool, dark pantry or cupboard is the ideal spot to stash them.
Why is it shelf-stable? Well, commercial processing involves high heat that effectively sterilizes the product, making it safe to store at room temperature.
How Long Does Unopened Dulce de Leche Last?
Check the “best by” or “use by” date on the can. Unopened dulce de leche can easily last for months past this date if stored correctly. Here’s a general guideline:
| Type of Container | Shelf Life |
| Unopened can | Up to 3 months past the “best by” date |
| Unopened jar | Check the product label |
Opened Dulce de Leche
Once you crack open that can or jar of dulce de leche, the rules change! Air exposure introduces the possibility of contamination and spoilage. Here’s the lowdown:
- Refrigeration: Opened dulce de leche must be refrigerated.
- Storage Container: Transfer any leftover dulce de leche from the can into an airtight container. This will keep it from drying out and absorbing fridge odors.
- Shelf Life: Refrigerated dulce de leche will usually stay good for about two weeks.
Homemade Dulce De Leche
If you’ve whipped up your own batch of dulce de leche, follow these guidelines:
- Refrigeration: Homemade dulce de leche is always best stored in the refrigerator.
- Storage Container: An airtight container is a must for your homemade creation.
- Shelf Life: Enjoy homemade dulce de leche within one week for maximum freshness.
How to Tell if Dulce de Leche has Gone Bad
Even with proper storage, dulce de leche can eventually go bad. Here are some signs to look out for:
- Mold: Any sign of mold means it’s time to toss the dulce de leche. Don’t try to scrape it off – mold can have invisible roots that extend into the product.
- Off-Odor: A sour or fermented smell is a sure sign your dulce de leche has spoiled.
- Texture Changes: Separation, lumpiness, or extreme dryness indicate it’s past its prime.
- Taste: If it tastes off, don’t take the risk. Just get rid of it.

Methods for Making Homemade Dulce de Leche
If you’re feeling adventurous, making your own dulce de leche is surprisingly easy! Here are a few popular methods:
- Slow Cooker Method: This hands-off approach is super simple.
- Pour a can of sweetened condensed milk into a slow cooker.
- Cover completely with water.
- Cook on low for 8-10 hours, or until the desired caramel color is achieved.
- Oven Method: Baking dulce de leche gives you great control over the final color and texture.
- Pour a can of sweetened condensed milk into an oven-safe dish.
- Cover tightly with foil.
- Place the dish into a larger baking pan and fill halfway with hot water.
- Bake at 425°F (220°C) for about 2 hours, or until your desired thickness is reached.
- Stovetop Method: This method is quickest but requires constant attention.
- Pour a can of sweetened condensed milk into a saucepan.
- Simmer over low heat, stirring continuously to prevent scorching.
- Cook until thickened and caramelized, about 1-2 hours.
Important Safety Note: If you use a can for any of these methods, do NOT attempt to open it while hot. The pressure buildup inside could cause the hot dulce de leche to explode outward. Always let the can cool completely before opening.

Freezing Dulce de Leche
Good news – you can freeze dulce de leche to extend its enjoyment! Here’s how:
- Portion: Divide the dulce de leche into smaller portions for easier defrosting. Ice cube trays work well for this!
- Freeze Individually (if applicable): If using an ice cube tray, freeze the dulce de leche portions solid before transferring them to a freezer-safe bag or container. This prevents them from sticking together.
- Label and Date: Label the container with the contents and the date of freezing.
How Long Can You Freeze Dulce de Leche?
Frozen dulce de leche will maintain its quality for up to three months. To thaw, simply place the desired amount in the refrigerator overnight.
Troubleshooting: Separation After Thawing
Sometimes, thawed dulce de leche might separate. Don’t worry – it’s still safe to eat! Give it a good stir to re-combine, or gently warm it in a saucepan over low heat while whisking continuously.

Does Dulce de Leche Need to be Refrigerated? – The Bottom Line
Whether you need to refrigerate your dulce de leche depends entirely on whether it’s store-bought and unopened, or if it’s been opened or homemade. Unopened store-bought dulce de leche has a long shelf life, but once opened or made from scratch, refrigeration is necessary to maintain its safety and quality.
