This 3-ingredient oven baked condensed milk dessert is the kind of simple little miracle I love to pull out when friends are coming over and I’m short on time. You literally pour a can of raw sweetened condensed milk straight into a roasting pan, add just two pantry ingredients, and let the oven do all the work. The result is a caramelized, custard-like treat that tastes like a cross between flan and a gooey bar cookie—sweet, silky, and rich with a golden top. It’s the kind of recipe that feels like a small-town potluck classic: humble ingredients, big comfort, and everyone asking, “Okay, but what did you put in this?”
Serve this warm or at room temperature, scooped into bowls or cut into soft squares. It’s lovely on its own, but a small spoonful of whipped cream or a scoop of vanilla ice cream makes it extra special. Fresh berries help balance the sweetness if you have them on hand. For a cozy family night, I like to pass around the pan with a stack of small plates and let everyone help themselves. A hot cup of coffee or tea for the grown-ups and cold milk for the kids rounds it out into a simple, homey dessert everyone can linger over.
3-Ingredient Baked Condensed Milk Custard
Servings: 6–8
Ingredients
1 (14-ounce) can sweetened condensed milk
2 large eggs
1 teaspoon vanilla extract (or 1 teaspoon ground cinnamon for a cozy twist)
Directions
Preheat your oven to 325°F (165°C). Place a metal roasting pan (8×8-inch or similar oven-safe metal pan) on the counter. Lightly grease the bottom and sides with a bit of butter or cooking spray so the dessert releases easily later.
Open the can of sweetened condensed milk and pour the thick, raw condensed milk directly into the center of the roasting pan. It will slowly spread out over the bottom—this is exactly what you want for that gooey, caramelized texture.
In a small bowl or liquid measuring cup, whisk the eggs and vanilla extract together until the mixture looks smooth and evenly blended. You don’t need to whip in a lot of air, just break up the yolks and combine everything well.
Pour the egg and vanilla mixture evenly over the layer of condensed milk in the roasting pan. Use a fork or a small whisk to gently swirl the top a few times, just enough to lightly mix without fully combining into one uniform color. Those subtle swirls help create a pretty, marbled, custardy texture when baked.
Tap the roasting pan gently on the counter to release any large air bubbles. Place the pan on the middle rack of the preheated oven. Bake for 30–35 minutes, or until the edges are set and lightly golden and the center still has a gentle wobble when you nudge the pan. A knife inserted near the edge should come out mostly clean, while the center stays soft.
Remove the roasting pan from the oven and set it on a cooling rack or a folded kitchen towel. Let the dessert cool in the pan for at least 20–30 minutes. As it cools, it will firm up into a scoopable, sliceable custard. For neater squares, let it cool to room temperature and then chill for 1–2 hours before cutting.
To serve, scoop the warm custard straight from the roasting pan with a spoon, or cut into squares and lift them out with a spatula. Spoon any caramelized condensed milk from the corners over the top of each serving so no one misses the best part.
Variations & Tips
For a cinnamon version, swap the vanilla for 1 teaspoon ground cinnamon and whisk it with the eggs before pouring over the condensed milk. You can also use 1/2 teaspoon vanilla plus 1/2 teaspoon cinnamon for a cozy, bakery-style flavor. If your family likes a little citrus, add 1 teaspoon finely grated lemon or orange zest to the egg mixture for a bright note that cuts the sweetness.
To dress this up for company, serve the warm custard over crumbled shortbread cookies or graham crackers in small bowls, or top with toasted chopped nuts after baking for a bit of crunch. For picky eaters, keep it plain and offer toppings on the side—sprinkles, mini chocolate chips, or a dollop of whipped cream let everyone customize their dish.
Food safety tips: Always use fresh, refrigerated eggs and avoid using cracked or dirty shells. Make sure the dessert is baked until the edges are set and the center is gently wobbly but not liquid; underbaked egg dishes can be unsafe. Let leftovers cool, then cover the roasting pan tightly and refrigerate within 2 hours of baking. Eat refrigerated leftovers within 3–4 days, and reheat individual portions gently in the microwave or enjoy chilled.
