Sweet Potato Recipe With Sweetened Condensed Milk: Caramelized Custard Clouds in One Pan

A sweet potato recipe with sweetened condensed milk transforms humble ingredients into something extraordinary—creamy, caramelized clouds that melt in your mouth.

This one-pan dessert combines the natural sweetness of roasted sweet potatoes with the rich depth of sweetened condensed milk, creating a texture that's impossibly tender yet sturdy enough to hold its shape.

I developed this recipe after realizing how often we overlook sweet potatoes as dessert stars, and the results speak for themselves.

The magic happens when you bake the sweet potatoes until they're fork-tender, then swirl in the condensed milk while still warm. This creates a silky custard-like center with a caramelized crust that's almost too pretty to eat—until you take that first bite.

The combination of warm spices like cinnamon and nutmeg enhances the natural sweetness of the potatoes, while a pinch of salt balances the richness. It's the kind of dessert that feels indulgent but comes together with minimal effort.

What you'll end up with is a dish that's equal parts comforting and elegant—perfect for holiday gatherings, cozy weeknight treats, or when you want to impress without spending hours in the kitchen. The aroma alone will have everyone gathering around your table, and the taste?

Pure, velvety perfection that pairs beautifully with a scoop of vanilla ice cream or a dollop of whipped cream. This recipe proves that sometimes the simplest ingredients create the most memorable desserts.

Ready in just 45 minutes with 5 simple ingredients, this dessert requires no special equipment beyond a baking sheet and mixing bowl. The best part? It doubles easily for crowds, and leftovers reheat beautifully—though I doubt you'll have any. Let's get baking!

Ingredients for sweet potato recipe with sweetened condensed milk

Five simple ingredients transform into velvety sweet potato clouds with caramelized edges.

The sweet potatoes are the heart of this dessert—choose firm, vibrant orange ones with no soft spots. Trader Joe's and Whole Foods carry the sweetest varieties, but your regular grocery store's organic section works too. Peel them first to save time later, then cut into even cubes (about 1.5 inches). The size matters—too big and they won't soften properly; too small and they'll overcook. For extra richness, I sometimes use orange sweet potatoes if available, but regular ones work perfectly fine. Just make sure they're fully peeled and dried before baking.

No sweetened condensed milk? Homemade version works—simmer 2 cups evaporated milk with 1 cup sugar until thickened—but store-bought is fine too. The Dulce de Leche brand has a slightly caramelized flavor that's worth hunting down. For the spices, Penzeys or bulk bins at natural markets offer the freshest ground cinnamon and nutmeg. If you only have whole nutmeg, grate it fresh—it makes a world of difference. The vanilla extract can be imitation, but pure Madagascar bourbon vanilla elevates this dessert to restaurant-quality. And if you're feeling fancy, swap the granulated sugar for turbinado sugar for subtle crunch.

This dessert reheats beautifully—just pop it in the oven at 350°F for 10 minutes. Store leftovers covered in the fridge for up to 5 days, though I've never had any last that long. For make-ahead convenience, assemble the dish (before baking) and refrigerate overnight—it develops even deeper flavor. The caramelized edges? That's where the magic happens—don't skip the final broil. And if you're serving a crowd, double the recipe—it's that good.

Step-by-step instructions for sweet potato custard clouds

This one-pan wonder transforms humble sweet potatoes into silky custard with a caramelized crown.

Preheat your oven to 375°F while you prepare the sweet potatoes. Peel and cut the 3 medium sweet potatoes into 1-inch cubes, ensuring they're all roughly the same size for even cooking. Place them in a medium pot and cover with 2 inches of cold water.

Bring to a boil over medium-high heat, then immediately reduce to medium-low and simmer for 8-10 minutes until the cubes are just tender when pierced with a fork. Drain thoroughly in a colander, shaking gently to remove excess water. This parboiling step prevents the potatoes from becoming too dry during baking.

In a medium bowl, whisk together the 1 can (14 oz) sweetened condensed milk, 0.5 cup granulated sugar, 2 tsp ground cinnamon, 0.5 tsp ground nutmeg, 0.25 tsp salt, and 1 tsp vanilla extract until completely smooth. The mixture should be silky and free of any lumps - this is your custard base. Here's the thing - using freshly ground spices makes a noticeable difference in flavor, so if you have them, freshly grind your cinnamon and nutmeg.

Melt the 2 tbsp unsalted butter in a small saucepan over low heat until completely liquid, then let it cool slightly. This butter will add richness and help create that signature caramelized crown on top of your custard.

Transfer the drained sweet potato cubes to a 9-inch oven-safe skillet or baking dish. Pour the custard mixture evenly over the potatoes, gently pressing down to ensure they're fully coated. The potatoes should be submerged in the custard mixture, but it's okay if they're not completely covered - the residual heat will help everything meld together.

Drizzle the melted butter evenly over the top of the custard mixture. This is where the magic happens - the butter will rise to the surface during baking, creating that beautiful caramelized crown. Place the dish on the middle rack of your preheated oven.

Bake for 45-50 minutes until the custard is set and the top has developed a deep golden brown caramelized crust. You'll know it's ready when the custard pulls away slightly from the edges of the pan and the top is firm to the touch. The center should still have a slight wobble, like a perfect custard.

Here's a pro tip: If you notice the custard browning too quickly before it's set, tent the pan with aluminum foil to prevent over-browning while allowing it to continue cooking. Remove from the oven and let it rest for 10 minutes before serving - this resting time allows the custard to fully set and the flavors to meld together.

Run a knife around the edges of the pan to loosen the custard, then invert onto a serving plate if desired. The custard should come out in one beautiful, golden cloud. Serve warm, straight from the oven, for the best texture and flavor experience.

For an extra touch, you can top with additional caramelized nuts or a sprinkle of cinnamon. This dish serves 6 generously, making it perfect for family gatherings or cozy dessert nights. The combination of sweet potatoes and sweetened condensed milk creates a texture that's both creamy and slightly firm, with a caramelized top that adds just the right amount of crunch.

Essential equipment for this dish

Oven-Safe Skillet

Your 9-inch oven-safe skillet is the star of this recipe—it needs to handle both stovetop prep and oven baking. I recommend a Le Creuset stoneware skillet for its even heat distribution and beautiful presentation, but any oven-safe ceramic or cast-iron skillet (like Lodge's pre-seasoned version) works perfectly.

If you don’t have one, a 9x9-inch baking dish with a tight-fitting lid will do the trick. Just make sure it’s oven-safe up to 400°F. 🔥

Mixing Bowl

A medium-sized mixing bowl (about 3-4 quarts) is essential for whisking the custard mixture smoothly. I prefer a stainless steel bowl from OXO—it’s durable and won’t retain flavors from other dishes.

If you’re short on space, a glass measuring cup with a whisk attachment works in a pinch. Just ensure it’s large enough to hold the 1 can of condensed milk without spills.

Measuring Tools

Precision matters here, especially with the spices and sugar. Use a set of stainless steel measuring spoons (like Kitchy’s magnetic set) for the 2 tsp cinnamon, 0.5 tsp nutmeg, and 0.25 tsp salt.
