Instructions
6 steps- 1
Combine milk and sugar: In a wide, heavy-bottomed saucepan, whisk together the whole milk and sugar. Bring to a gentle simmer over medium heat, stirring to dissolve the sugar.
- 2
Add baking soda: Once simmering, carefully whisk in the baking soda. The mixture will froth and bubble up rapidly, which is normal.
- 3
Simmer patiently: Reduce the heat to low. Allow the mixture to simmer gently for 1.5 to 2 hours. Stir occasionally at first, then more frequently as the mixture reduces and thickens to prevent burning.
- 4
Monitor color: The milk will slowly turn from white to a deep, rich caramel brown due to the Maillard reaction.
- 5
Test consistency: It is done when the mixture thickly coats the back of a spoon and leaves a clear path when you draw a line through it.
- 6
Finish: Remove from heat and stir in the vanilla extract. Pour into a glass jar and let cool completely (it will thicken further as it cools).

Cultural context
Dulce de leche is a South American milk caramel, made by cooking milk and sugar slowly until the sugars brown and the mixture thickens into a spreadable, deeply caramelized paste. It's claimed across several countries including Argentina and Uruguay as a defining national confection, used as a filling, spread, or dessert component on its own.
Listahan note
This version cooks the milk and sugar mixture low and slow with frequent stirring, since rushing the heat scorches the sugars unevenly before the milk has had time to reduce and thicken properly.
Technique cues
- Simmering milk and sugar together over low heat for an extended time lets the sugars caramelize gradually rather than burning before the mixture thickens.
- Stirring regularly, especially as the mixture reduces and thickens, prevents the milk solids from catching and scorching on the bottom of the pot.
- A pinch of baking soda added early raises the pH slightly, which speeds up the browning reaction that gives dulce de leche its characteristic color.
- Cooking until the mixture coats the back of a spoon and holds a slow drip signals it's reached the right thickness before cooling.
Kitchen flow
- Parallel prep
- While Dulce de Leche is in the oven, measure out any garnish or topping — like the milk — so it's ready the moment the bake finishes cooling. Plan around the simmer; that's the slow part.
- Make-ahead
- Dulce de Leche's dough or batter (built around milk) can usually be made a day ahead and refrigerated, then baked fresh — many doughs actually improve with an overnight rest. Everything else is quick — the simmer is the one step that takes real time.
- Leftover move
- Leftover Dulce de Leche freezes well — wrap individual portions tightly and thaw at room temperature, or crumble it over ice cream for a quick second life. This one leans on the milk. Everything else is quick — the simmer is the one step that takes real time.
- Cleanup rhythm
- Soak the mixing bowl and beaters for Dulce de Leche right away — sugar and butter residue hardens fast once it cools. This one leans on the milk. The simmer step is what sets the pace here.
Ingredient brief
Role, handling, and swap guidance for each key ingredient.
4 cups whole milk
Richness and texture
Purpose: cups whole milk rounds the texture and helps the dish feel complete.
Handling: Prep before heat is high so the cooking step can move without rushing.
Adaptation: Use unsweetened dairy-free alternatives only where they still provide enough fat and body.
1 cup granulated sugar
Sweetness and aroma
Purpose: cup granulated sugar adds aroma, sweetness, or warmth without needing extra garnish.
Handling: Measure before heating and break up clumps so the mix distributes evenly.
Adaptation: Use the closest fresh equivalent and expect a modest shift in flavor or texture.
1/4 tsp baking soda
Flavor support
Purpose: tsp baking soda supports the balance of Dulce de Leche and should taste integrated.
Handling: Prep before heat is high so the cooking step can move without rushing.
Adaptation: Use the closest fresh equivalent and expect a modest shift in flavor or texture.
1 tsp vanilla extract
Sweetness and aroma
Purpose: tsp vanilla extract adds aroma, sweetness, or warmth without needing extra garnish.
Handling: Prep before heat is high so the cooking step can move without rushing.
Adaptation: Use the closest fresh equivalent and expect a modest shift in flavor or texture.
Technique notes
- Dulce de leche continues to thicken as it cools, so it should look slightly looser than the final desired texture while still warm.
- Store in a sealed jar in the refrigerator, where it keeps for weeks, and warm gently before using if it's stiffened.
- Use it as a spread, a filling between cookies, or a topping for ice cream without needing to cook it further.
Ingredient swaps
- Dairy-free direction
- Swap the milk for a neutral dairy-free butter and a full-fat plant milk (oat or coconut give the closest richness) — the texture shifts slightly but the dish holds together.
- Lower-sodium direction
- Season lighter on salt than the recipe calls for, then adjust right before serving — it's easier to add more than to fix an oversalted batch. Clock it at close to 120 minutes to feed 8. It's a South American dish through and through. The ingredient list here is 4 items long.
- Weeknight shortcut
- Mix and chill the batter or mix-ins up to a day ahead so the night-of step is just baking, not mixing. Clock it at close to 120 minutes to feed 8. South American technique drives this recipe. Count the ingredient list and it's 4 deep.
Serve alongside
- Fresh berries
- Citrus fruit salad
- Mint leaves
- Black coffee
- Hot tea

Equipment
- Mixing bowls
