Sweet potato cupcakes transform the beloved Thanksgiving side dish into a perfectly portioned dessert that captures all the cozy flavors of the holiday season. These soft, moist cupcakes feature the natural sweetness of sweet potatoes enhanced with warm cinnamon and a hint of ginger, creating a tender crumb that melts in your mouth. Topped with a cloud-like marshmallow buttercream, they cleverly reimagine the classic sweet potato casserole in handheld form—complete with that irresistible marshmallow topping that gets everyone excited for dessert.
I first experimented with these cupcakes when hosting a Friendsgiving where several guests needed to leave early. The solution? A dessert they could easily take with them! These cupcakes were such a hit that they've become my signature contribution to fall gatherings. There's something magical about the way the sweet potato adds incredible moisture while the spices create that perfect autumn warmth—and the fluffy marshmallow frosting takes them over the top in the most delightful way.
Simple Seasonal Ingredients
- Sweet potato puree: Creates ultra-moist cupcakes with natural sweetness and beautiful color
- Warm spices: Cinnamon and ginger bring those classic sweet potato casserole flavors to life
- Vanilla extract: Enhances the natural sweetness with subtle aromatic notes
- Vinegar: Works with baking soda to create a perfect rise without eggs
- Marshmallow extract: Gives the frosting that authentic marshmallow flavor without needing actual marshmallows
The versatility of these cupcakes is part of what makes them so special. Any variety of sweet potato works beautifully—from the traditional orange-fleshed ones to purple or white varieties. I typically roast fresh sweet potatoes for the most intense flavor, but canned sweet potato puree (not pie filling) works perfectly when time is short. The recipe also accommodates various dietary needs, working well with plant-based milk and oil-free substitutions.
Creating Perfect Cupcakes
- Prepare The Wet Ingredients:
- In a large mixing bowl, combine sweet potato puree, water or milk of choice, vanilla extract, vinegar, and oil. This mixture creates the moist foundation for your cupcakes. Let it sit for about 10 minutes while you prepare the oven and cupcake liners, allowing the flavors to meld.
- Mix The Batter:
- Add the flour, sugar, baking powder, baking soda, salt, cinnamon, and ginger to the wet ingredients, stirring just until combined. This gentle mixing prevents gluten development, ensuring your cupcakes stay tender rather than tough. The batter will be fairly thick but still scoopable.
- Portion Carefully:
- Divide the batter among nine lined cupcake wells, filling each about two-thirds full. This specific amount ensures the cupcakes rise properly without overflowing or remaining too flat. For perfectly even cupcakes, use an ice cream scoop with a release mechanism.
- Bake With Precision:
- Bake in a preheated 350°F oven for exactly 18 minutes. The cupcakes should rise beautifully with slightly domed tops, and a toothpick inserted in the center should come out clean or with a few moist crumbs. The precise timing prevents dry cupcakes while ensuring they're completely baked.
- Cool Completely:
- Allow the cupcakes to cool in the pan for 5 minutes before transferring to a wire rack to cool completely. Patience here is key—attempting to frost warm cupcakes will result in melted frosting. For the best texture and flavor, refrigerate overnight very loosely covered.
- Create Cloud-Like Frosting:
- Whip butter or plant-based butter with powdered sugar, vanilla extract, and marshmallow extract until light and fluffy. This marshmallow buttercream perfectly mimics the topping on traditional sweet potato casserole while being stable enough to pipe beautifully.
My favorite memory with these cupcakes was bringing them to a Thanksgiving potluck where several guests couldn't eat traditional desserts due to egg allergies. Watching their faces light up when they realized they could enjoy these cupcakes without worry made all the effort worthwhile. One friend later told me it was the first time in years she felt included in the dessert portion of Thanksgiving—a reminder of how food can bring people together.
Serving Suggestions
Serve these cupcakes slightly chilled for the best texture and flavor. For a dramatic presentation, pipe the marshmallow buttercream high on each cupcake and lightly toast the frosting with a kitchen torch to mimic the browned marshmallows on a sweet potato casserole. Arrange on a tiered stand with fresh sage leaves or small cinnamon sticks as garnish for a stunning Thanksgiving dessert table centerpiece. These cupcakes pair beautifully with coffee, spiced cider, or even a small glass of bourbon for an adults-only treat.

Creative Variations
Transform this basic recipe by adding a cranberry jelly filling to mimic another Thanksgiving favorite. Create a streusel-topped version by sprinkling a mixture of brown sugar, flour, and chopped pecans on top before baking. Make a "sweet potato pie" version by adding a graham cracker crust to the bottom of each liner before filling with batter. For a maple twist, replace some of the sugar with maple syrup and add maple extract to the frosting. During winter holidays, add a touch of nutmeg and clove to the spice blend for a more complex flavor profile.
Storage Solutions
Store frosted cupcakes in an airtight container in the refrigerator for up to 5 days. The sweet potato keeps them moist far longer than traditional cupcakes. For make-ahead convenience, freeze unfrosted cupcakes for up to 3 months, wrapped individually in plastic wrap and stored in a freezer bag. Thaw overnight in the refrigerator before frosting. The marshmallow buttercream can be made up to 3 days ahead and stored in the refrigerator—just bring to room temperature and rewhip before using.

Frequently Asked Questions
- → How do I make sweet potato puree for this recipe?
- To make sweet potato puree, wash a medium sweet potato and pierce it several times with a fork. Either bake it at 400°F for 45-60 minutes until very soft, or microwave for 5-8 minutes until tender. Let it cool slightly, then peel and mash with a fork until smooth. You can also use a food processor for an extra-smooth texture. One medium sweet potato typically yields about 1 cup of puree.
- → Can I make these cupcakes gluten-free?
- Yes! Simply use a gluten-free all-purpose flour blend in place of the regular flour. Look for a blend that contains xanthan gum for the best texture results. Bob's Red Mill 1-to-1 Baking Flour and King Arthur Measure for Measure are both good options that work well in this recipe.
- → What kind of frosting pairs well with these cupcakes?
- These cupcakes pair beautifully with cream cheese frosting (regular or vegan), maple buttercream, cinnamon frosting, or even a simple glaze made from powdered sugar and a splash of milk or maple syrup. For a healthier option, try a lightly sweetened Greek yogurt topping with a sprinkle of cinnamon.
- → Why do the cupcakes taste better the next day?
- Like many spiced baked goods, these cupcakes benefit from resting time which allows the flavors to meld and deepen. The moisture from the sweet potato also continues to distribute evenly throughout the cupcake, improving the texture. Additionally, the cupcake liners release more easily after the cupcakes have had time to set completely.
- → Can I add mix-ins to these cupcakes?
- Absolutely! Try adding ⅓ cup of chopped nuts (walnuts or pecans work well), ¼ cup of raisins or dried cranberries, or even ¼ cup of mini chocolate chips. For extra autumn flavor, you could also add ½ teaspoon of pumpkin pie spice along with the cinnamon and ginger.
