Top 25 Sweetened Condensed Milk Recipes: Cakes, Flan, Fudge and More

Sweetened condensed milk is already cooked — the milk has been heat-treated and concentrated — which means it behaves differently from fresh milk or cream in a recipe. It browns faster in the oven because it is high in sugar and milk solids, both of which darken readily with heat. This is a benefit in a caramel sauce or dulce de leche but can mean over-browning in cakes if the oven is too hot. Baking condensed milk recipes at a moderate 170–180°C / 340–350°F rather than a hot oven reduces this.

In flan and custard, condensed milk provides both the sweetener and much of the fat and protein that allow the custard to set. A standard flan ratio uses one tin of condensed milk with one tin of evaporated milk (or whole milk) and three to four eggs. The condensed milk makes the flan sweeter and more stable than an all-fresh-milk recipe. Do not try to substitute evaporated milk for condensed milk in flan — they behave completely differently and the result will not set correctly.

In no-bake fudge and sweets, condensed milk is the key ingredient because it already contains the right ratio of sugar to milk solids to set when combined with chocolate or cooked briefly on the stove. Brazilian brigadeiros and many Indian sweets rely on this property. The fat in condensed milk prevents crystallisation, giving a smooth, creamy fudge rather than a grainy one — which is why recipes that use condensed milk as the base rarely require a candy thermometer.

Homemade sweetened condensed milk requires only two ingredients: full-fat milk and sugar. Combine 1 litre of whole milk with 200–250 g of sugar in a heavy-bottomed pan, bring to a gentle simmer and cook uncovered over low-medium heat for forty to fifty minutes, stirring regularly, until reduced by roughly half and thickened to a pourable syrup consistency. It will thicken further as it cools.

Stir more frequently as it thickens because the bottom scorches easily once enough water has evaporated. A silicone spatula that reaches the bottom corners is better than a wooden spoon for this. If you see any browning on the bottom, turn down the heat immediately — a slightly scorched condensed milk will taste burnt throughout. The finished condensed milk should coat a spoon and drip slowly, not pour freely.

For dairy-free condensed milk, coconut milk works well: use full-fat tinned coconut milk and follow the same reduction process. It takes slightly less time to thicken because coconut milk is already richer than dairy milk, and the finished product has a mild coconut flavour that works well in most dessert recipes. Oat milk can also be used but results in a thinner, less rich product that is better suited to drinks and light desserts than to fudge or flan.

Condensed milk is not a direct substitute for fresh milk — it is much sweeter and much thicker. If a recipe calls for condensed milk and you only have evaporated milk, mix it with an equal volume of sugar and simmer briefly until the sugar dissolves. The result is close enough for most purposes. Conversely, if a recipe calls for evaporated milk you cannot substitute condensed milk without removing significant sugar from the recipe elsewhere.

In no-churn ice cream, condensed milk replaces both the sugar and the stabiliser in the base — the sugar concentration is high enough to keep the ice cream soft and scoopable without an ice cream maker. This is why condensed milk-based no-churn ice creams are so reliable: the ratio is essentially fixed at one tin of condensed milk to 500 ml of whipped cream. Any flavouring — cocoa powder, vanilla extract, instant coffee, fruit puree — can be folded in without adjusting the base.

In fudge and sweet recipes, condensed milk can often replace both the cream and the sugar in a standard recipe, streamlining the process. Add 200 g of dark chocolate to one tin of condensed milk heated over a bain-marie, stir until smooth and pour into a lined tin to set. After two hours in the fridge you have a smooth, dense chocolate fudge with nothing more than those two ingredients. This ratio — one tin to 200 g of chocolate — is one of the most useful things to memorise in sweet-making.

An opened tin of condensed milk should be transferred to a clean sealed jar or airtight container — the tin can impart a metallic taste after the first twenty-four hours and is not food-safe for long-term storage once opened. In the fridge in a sealed container it keeps for up to two weeks without any quality loss. A film of clingfilm pressed onto the surface before sealing prevents a skin forming on top.

If you only used part of a tin, the remaining condensed milk is useful in coffee (it is the base for Vietnamese iced coffee), stirred into oatmeal instead of sugar and cream, drizzled over fruit, or used as a dip for fresh bread. It is stable enough at room temperature to sit on the counter for a day while you find other uses. Do not leave it in the tin, though — decant and cover.

Condensed milk can be frozen for up to three months in a sealed container with a little headroom for expansion. Thaw overnight in the fridge and stir well before using — it sometimes separates slightly when frozen and thawed, but a good stir brings it back. Frozen-then-thawed condensed milk works fine in baking, flan and fudge, though for coffee or drinks where the texture matters the fresh version is better.
