Sweet Potato Cupcakes with Marshmallow Frosting

Happy Monday friends!! I hope you had a good weekend and are getting ready for the holiday season. We went to the mall this weekend to get a few winter items for the baby and I was surprised to find out that we are full-on holiday shopping mode. Not only was the mall packed with humans, but it was also all decked out for Christmas. I am NOT ready for this but with only two weeks to Thanksgiving, I guess I have no choice. This is why I focus on sweets. These sweet potato cupcakes with marshmallow frosting are next on my Thanksgiving dessert crawl.

Everyone hails the pumpkin for Thanksgiving. From pumpkin pie to pumpkin cake, it’s all about the pumpkin. But I think sweet potatoes need more love besides being a side dish. I am guilty of this too because, besides this brown butter sweet potato bread, I have no other sweet potato recipe. But thanks to these sweet potatoes cupcakes and an upcoming sweet potato pie, I am hailing sweet potatoes this fall.

These cupcakes are of course inspired by my favorite Thanksgiving side dish – sweet potato casserole. These cupcakes start with a browned butter batter filled with homemade sweet potato puree. The cupcake bakes into a sweet moist little cake thanks to the sweet potato.

The cupcakes are finally topped with a fluffy marshmallow buttercream. I didn’t use my usual marshmallow frosting in these spiced apple cupcakes but instead, I wanted a smooth, silky buttercream with the marshmallow flavor. I used marshmallow fluff in the buttercream for this and it was an incredible blend. Just the perfect topping to a perfectly spiced cupcake.

Prep Time 30 minutes
Cook Time 15 minutes


For Cupcakes:

  • 1 ¼ cup all-purpose flour
  • 1 ¼ teaspoons baking soda
  • ¼ teaspoon kosher salt
  • ½ teaspoon ground cinnamon
  • ¼ teaspoon ground nutmeg
  • 1/3 cups brown sugar, packed
  • 1 large egg
  • 2 teaspoons pure vanilla extract
  • ½ cup unsalted butter, melted, browned and cooled
  • 2/3 cup sweet potato puree
  • ½ cup whole milk

For Frosting:

  • ¾ cup unsalted butter softened
  • 1 ½ cups marshmallow fluff
  • 2 teaspoons pure vanilla extract
  • 3 cups powdered sugar


  1. Preheat oven to 350 degrees F. Prepare a cupcake tin with liners.
