Ingredients
4 medium sweet potatoes
Peel and cut the sweet potatoes into 1-inch cubes. Sweet potatoes provide the naturally creamy, tender base of the dessert and become wonderfully soft as they bake.
1 cup brown sugar
Brown sugar supplies the main sweetness while adding a deeper molasses-like caramel flavor. As it melts with the butter, it creates the glossy syrup that makes this dessert so irresistible.
1/2 cup unsalted butter, melted
Butter brings richness and helps transform the brown sugar and cinnamon into a luscious coating. Using unsalted butter also gives you better control over the final flavor.
1 teaspoon ground cinnamon
Cinnamon adds warm spice and makes the sweet potatoes taste especially cozy and aromatic. It is a simple ingredient, but it gives the dessert that unmistakable homemade comfort-food flavor.
How to Make 4-Ingredient Oven-Baked Sweet Potato Dessert
1. Prepare the oven and pan
Preheat your oven to 375°F. Lightly grease an oven-safe metal baking pan to help prevent sticking and make serving easier.
2. Add the sweet potatoes
Place the raw cubed sweet potatoes directly into the prepared baking pan. Spread them into an even layer so they cook as consistently as possible.
3. Add the butter, brown sugar, and cinnamon
Pour the melted butter evenly over the sweet potatoes. Sprinkle the brown sugar and cinnamon across the top, distributing them as evenly as possible.
There is no need to make a separate sauce. Everything comes together naturally in the oven.
4. Cover and bake
Loosely cover the pan with foil and bake for 30 minutes. Covering the pan initially helps the sweet potatoes soften as they begin cooking.
5. Uncover and finish baking
Carefully remove the foil and gently stir the sweet potatoes so the buttery brown-sugar mixture can coat the pieces.
Return the pan to the oven and bake uncovered for another 20 to 25 minutes, or until the sweet potatoes are fork-tender and the syrup is bubbling around the edges.
6. Let it rest
Remove the pan from the oven and allow the dessert to rest for 5 to 10 minutes. This gives the syrup a little time to thicken and cling beautifully to the warm sweet potatoes.
Pro Tips for Perfect Sweet Potato Dessert
Cut the sweet potatoes evenly. Try to keep the cubes close to 1 inch in size. Uniform pieces cook more evenly and help prevent some pieces from becoming overly soft while others are still firm.
Don’t skip the foil at the beginning. The initial covered baking time helps the sweet potatoes become tender before the uncovered portion encourages the syrup to thicken and caramelize.
Give everything a gentle stir. After removing the foil, carefully turn the sweet potatoes through the syrup so every piece gets coated.
Watch the final baking time. Ovens vary, so start checking around the 20-minute mark after uncovering. You want tender sweet potatoes and bubbling syrup, not burnt sugar.
Let it rest before serving. Those extra few minutes allow the buttery brown-sugar coating to settle and become thicker.
Easy Variations
Sweet Potato Pecan Dessert
Add a handful of chopped pecans or walnuts during the final 10 minutes of baking for a delicious nutty crunch.
Extra Creamy Serving
Top warm portions with a scoop of vanilla ice cream. The contrast between the hot, syrupy sweet potatoes and cold, creamy ice cream is especially delicious.
Whipped Cream Version
Add a generous spoonful of whipped cream just before serving for an easy dessert that feels perfect for Sunday dinner or the holidays.
Extra-Cinnamon Flavor
If you love warm spices, add a little extra cinnamon to taste. You can also combine cinnamon with a tiny pinch of nutmeg for a more holiday-inspired flavor.
What to Serve With It
This baked sweet potato dessert is wonderful on its own, but it also makes a beautiful ending to a comforting family meal.
For a savory dinner, serve it after baked chicken, roasted pork chops, meatloaf, or glazed ham. The natural sweetness of the potatoes creates a delicious contrast with savory main dishes.
For a holiday table, serve small portions alongside turkey, ham, roasted vegetables, and homemade dinner rolls.
And for dessert, simply add vanilla ice cream, whipped cream, or chopped pecans and serve it warm.
How to Store Leftovers
Allow leftovers to cool, then cover and refrigerate for up to 3 days.
To reheat, warm individual portions gently in the microwave or place the sweet potatoes in a baking dish and warm them in the oven. Spoon some of the brown-sugar syrup from the pan over the top before serving.
