Making Homemade Sweetened Condensed Milk is surprisingly easy and requires just two simple ingredients. It’s a great trick to have up your sleeve when you run out of the canned version or if you want to avoid the additives and preservatives found in many store-bought brands.
This version is creamy, sweet, and perfect for any recipe that calls for sweetened condensed milk, from key lime pie to Thai iced tea or even just mixed into your coffee.
Homemade Sweetened Condensed Milk
This recipe uses the stovetop method for a rich, thick, and authentic result.
Prep time: 1 minute
Cook time: 15-20 minutes
Cooling time: 1 hour+
Yield: About 1 ½ cups (equivalent to one standard 14 oz can)
Ingredients
· 2 cups (480 ml) whole milk (Do not use skim or low-fat milk; the fat is essential for creaminess.)
· ⅔ cup (135 g) granulated sugar (You can also use organic cane sugar or even brown sugar for a caramel-like flavor.)
Optional Enhancements:
· 2 tablespoons unsalted butter (adds richness and a smoother texture, similar to commercial brands)
· Pinch of salt (balances the sweetness)
Instructions
- Combine Ingredients: In a medium-sized, heavy-bottomed saucepan (a heavy bottom is important to prevent scorching), combine the whole milk and sugar.
- Heat and Dissolve: Place the pan over medium heat. Stir continuously with a whisk or heatproof spatula until the sugar has completely dissolved and the milk is hot but not yet boiling. This takes about 3-4 minutes.
- Simmer and Reduce:
· Once the sugar is dissolved, reduce the heat to low.
· Switch to a silicone spatula or wooden spoon for stirring. Let the mixture come to a gentle simmer—you want small bubbles around the edges, not a rolling boil.
· Cook, stirring frequently, for about 15-20 minutes. The mixture will slowly reduce and thicken. Stirring frequently prevents a skin from forming and stops the milk from scorching on the bottom. - Check for Doneness:
· The mixture is done when it has reduced by about half and has a creamy, slightly thickened consistency. It should coat the back of a spoon.
· The Cold Saucer Test: Place a small saucer in the freezer for a few minutes. Drop a small spoonful of the milk mixture onto the cold saucer. Let it sit for 30 seconds. If it thickens to a syrupy consistency similar to store-bought condensed milk, it’s ready. Remember, it will thicken further as it cools. - Finish (Optional): If you are using butter and salt, remove the pan from the heat and stir them in now until melted and fully incorporated.
- Cool and Store:
· Pour the finished sweetened condensed milk through a fine-mesh strainer into a heatproof jar or bowl. This ensures a perfectly smooth texture.
· Let it cool completely to room temperature. It will thicken significantly as it cools.
· Once cool, cover tightly and store in the refrigerator for up to 2 weeks.
Why This Works & Troubleshooting
· The Science: You are simply evaporating the water content from the milk, leaving behind a concentrated, sweet, and creamy liquid. The sugar acts as a preservative, which is why it lasts so long in the fridge.
· It’s Too Thin: If your milk hasn’t thickened after 25 minutes, you may not have simmered it long enough, or the heat was too low. Simply continue simmering for a few more minutes, watching it closely. It’s better to err on the side of slightly underdone than burnt.
· It’s Grainy: This can happen if the sugar wasn’t fully dissolved before the mixture started simmering, or if it boiled too vigorously. Constant stirring helps prevent this.
· It Scorched on the Bottom: This happens if the heat was too high or you stopped stirring. If you get a few dark specks, straining the final product through a fine-mesh sieve will save it.
How to Use It
Use this homemade version in any recipe that calls for sweetened condensed milk:
· Desserts: Key Lime Pie, Tres Leches Cake, Fudge, Flan.
· Drinks: Thai Iced Tea, Vietnamese Iced Coffee.
· Topping: Drizzle over fresh fruit, ice cream, or pancakes.
It’s a simple, rewarding kitchen staple that tastes far better than anything from a can
