  • 1 cup cooked, mashed purple sweet potato (from about 1 small-medium sized potato -- see notes)
  • cup buttermilk
  • 2 large eggs
  • ½ cup olive oil
  • 1 tablespoon granulated sugar
  • ¾ teaspoon sea salt
  • 1⅓ cup all-purpose flour
  • teaspoons baking soda
  • 1 cup Gruyère cheese, divided
  • 1 tablespoon plus 1/2 teaspoon fresh rosemary, finely chopped
  • 2 tablespoons unsalted butter, softened to room temperature


  • Preheat the oven to 350°F, and adjust a rack to the center. Line a muffin tin with 12 paper cups. Set aside.
  • In a large mixing bowl, combine the mashed sweet potato (see notes on how to mash the potato), buttermilk, eggs, oil, sugar and salt. Mix until smooth -- you can use an electric mixer if that's easier.
  • Add the flour and baking soda and mix only until it's incorporated.
  • Fold in ⅔ cup of the grated cheese and the rosemary.
  • Fill each paper muffin cup about ¾ the way up with the batter.
  • In a small bowl, mix the softened butter with the remaining 1/3 cup of grated cheese and then evenly distribute this on top of each batter-filled cup.
  • Bake in the preheated 350°F oven until the muffins are set and becoming golden, 20 to 25 minutes.
  • Let them cool for at least 10 minutes before serving.


To mash the potato: Peel and then cut the potatoes into large chunks. Place them in a steamer over boiling water and cover. Steam until the potatoes are fork tender, about 10 minutes. Remove them from the steamer and use a fork to mash them immediately. Let them cool to room temperature before using them in the recipe.
