Have you ever wondered does boiling a can of condensed milk turn into caramel? It sounds like a kitchen hack too good to be true, but the answer is a resounding yes! When sweetened condensed milk is boiled long enough, it transforms into a rich, creamy caramel-like sauce that is both versatile and delicious. In this article, we’ll dive deep into the process, explore different methods, address safety concerns, and provide tips on how to make the perfect caramel from condensed milk.
What is Sweetened Condensed Milk?
To begin with, it’s important to understand what sweetened condensed milk is. It’s a thick, sugary milk product made by removing most of the water from cow’s milk and adding sugar. To explore more creative ideas, check out our article on What Are the Common Uses of Condensed Milk?. This results in a concentrated, syrupy liquid used in many dessert recipes. Its high sugar content makes it the ideal candidate for caramelization. However, you might be curious, does condensed milk turn into caramel when boiled?
Yes, it does! When heated for a long period, the sugars in condensed milk caramelize, turning the liquid into a golden brown, thick, sweet sauce. That is to say, it’s an easy way to create caramel-like flavors without the need for complex ingredients.
The Science Behind Caramelization
The transformation of sweetened condensed milk into caramel is all about chemistry. Sugar undergoes caramelization when exposed to high heat. During this process, the sugars in the condensed milk break down and recombine into new molecules that give caramel its distinct flavor, color, and texture.
Moreover, heating the milk causes water to evaporate, further thickening the sauce. You can also try other recipes featuring this ingredient, like in our Condensed Milk Recipes: Sweet and Savory Dishes. In the case of condensed milk, its high sugar content accelerates this caramelization process. As a result, you get a smoother and creamier caramel compared to making caramel from just sugar and water. In other words, sweetened condensed milk contains everything needed for caramel in one can—sugar, milk, and water.
Methods to Turn Condensed Milk into Caramel
There are multiple ways to make caramel from condensed milk, ranging from the classic can-boiling method to faster stovetop options. Let’s explore each method in detail, so you can decide which is best suited to your needs and preferences.
Boiling the Can Method
The most traditional and well-known method is to boil the entire unopened can of condensed milk. This technique has been popular for decades and produces consistent results.
Steps for Boiling a Can:
- Start by removing the paper label from the can.
- Place the can in a large pot, ensuring it’s fully submerged in water.
- Bring the water to a boil, then reduce the heat to a simmer.
- Allow the can to simmer for 2 to 3 hours. Simmering for 2 hours results in a lighter caramel, while 3 hours yields a thicker, darker caramel.
- Throughout the boiling process, make sure the water level stays above the can. You may need to add more boiling water to maintain the level.
- After boiling, let the can cool completely before opening it to avoid any accidents.
Safety Tip: Boiling a can of condensed milk can be dangerous if not done correctly. Most importantly, never open the can while it’s hot. The pressurized steam inside could cause the contents to burst out, potentially causing burns. Therefore, always wait for the can to cool down fully before opening.
However, if you’re nervous about boiling a can, there are safer and equally effective alternatives.
Stovetop Method
If boiling a can seems risky, you can make caramel from condensed milk directly on the stovetop. For more delicious dishes made with this ingredient, explore our article on What Can I Do With A Can Of Condensed Milk?. This method is faster and avoids the dangers of an unopened can.
Steps for Stovetop Caramel:
- Pour the condensed milk into a heavy-bottomed saucepan.
- Set the heat to low to prevent scorching.
- Stir constantly with a wooden spoon or spatula as the milk thickens and darkens.
- Continue stirring until the desired caramel color and thickness are reached. This usually takes 20 to 30 minutes.
The stovetop method requires constant attention, but it eliminates the risks associated with boiling a can. Moreover, you have more control over the texture and consistency of your caramel.

Oven Method
Another method that minimizes risk is baking the condensed milk in the oven. This approach is more hands-off compared to the stovetop method.
Steps for Oven Caramel:
- Preheat your oven to 425°F (220°C).
- Pour the sweetened condensed milk into a glass baking dish.
- Cover the dish tightly with aluminum foil.
- Place the baking dish inside a larger pan, then fill the larger pan with water to create a water bath.
- Bake for 60 to 90 minutes, checking the caramel occasionally for consistency.
The oven method is less labor-intensive because you don’t have to stir constantly. However, it takes longer than the stovetop method, but the results are well worth the wait. Be sure to use a water bath, as it helps maintain an even temperature and prevents the milk from burning.
Instant Pot Method
For those who want quicker results with minimal effort, the Instant Pot is an excellent choice. By using a pressure cooker, you can make condensed milk caramel in about half the time it takes using the traditional methods.
Steps for Instant Pot Caramel:
- Place the unopened can of sweetened condensed milk on the trivet inside your Instant Pot.
- Add enough water to cover the can by at least 1 inch.
- Set the Instant Pot to high pressure for 40 minutes.
- After the timer goes off, let the pressure release naturally.
- Allow the can to cool completely before opening.
The pressure-controlled environment of the Instant Pot reduces the risk of the can exploding, and it speeds up the process significantly. However, safety precautions still apply—never open a hot can.
Dulce de Leche vs. Caramel: What’s the Difference?
It’s important to understand that when you boil a can of condensed milk, you’re actually making dulce de leche rather than traditional caramel. Though both are delicious, there are subtle differences between the two.
Differences Between Dulce de Leche and Caramel:
- Ingredients: Caramel is made primarily from sugar, sometimes with the addition of cream or butter. Dulce de leche, however, is made from milk and sugar.
- Texture: Caramel tends to have a silkier, smoother texture. In contrast, dulce de leche is thicker and creamier, thanks to the milk content.
- Flavor: Caramel has a more intense, sometimes slightly burnt flavor. Dulce de leche, on the other hand, is milkier and sweeter, offering a more rounded flavor profile.
Consequently, if you’re aiming for a creamy, milk-based caramel sauce, boiling condensed milk into caramel will give you what you’re looking for. However, if you prefer the traditional burnt sugar taste of caramel, you might want to stick with standard caramel recipes that rely on sugar alone.

How Long Should You Boil a Can of Condensed Milk?
Timing is critical when you want to make the perfect condensed milk caramel. The time you boil the can determines the thickness and depth of flavor in your caramel.
- For a lighter caramel: Boil the can for 2 hours. The result will be a smoother, pourable sauce ideal for drizzling over desserts.
- For a thicker caramel: Boil for 3 hours. This yields a richer, more spreadable caramel, perfect for spreading on toast or using as a pie filling.
Regardless of how long you boil it, be sure the can is submerged in water the entire time. If the water level drops too low, the can could overheat and burst. Therefore, keeping an eye on the water level is crucial for both safety and achieving the right consistency.
