Instructions

  • Sweet Potato Prep: Wash, dry, and poke the Japanese sweet potato all over with a fork. Add it to a baking sheet and roast it at 400F (204C) until soft, about an hour. Cook time will depend on the size - I used 3 small ones. You can do this step up to 3 days in advance and store them in the fridge. Preheat your oven to 350F (175C). Line a muffin tin with 6 liners or grease well.
    A hand holds a roasted sweet potato on a baking tray with other sweet potatoes, bathed in sunlight—perfect for making Healthy Sweet Potato Muffins.
  • In a large bowl, mash the cooked Japanese sweet potato until smooth. Add the eggs, milk, maple syrup or honey, and vanilla. Mix well.
    Milk being poured into a white bowl containing two raw eggs and mashed bananas, perfect for preparing Healthy Sweet Potato Muffins, set on a wooden surface.
  • Add the flour, baking powder, baking soda, salt, and cinnamon (if using) to the bowl. Stir gently until just combined. Do not overmix.
    A hand holds a glass bowl containing flour, baking powder, and cinnamon above a larger white bowl with a yellow mixture on a wooden surface—perfect for making Healthy Sweet Potato Muffins.
  • With a large cookie scoop, divide the batter evenly into 6 muffin cups, filling each about 3/4 full.
    A six-cup muffin tray lined with paper cups, each filled with healthy sweet potato muffins batter, sits on a wooden surface, ready to be baked.
  • Bake for 18-22 minutes at 350F (17%C), or until a toothpick inserted in the center comes out clean. Mine took 22 min. Let cool in the pan for 5 minutes before transferring to a wire rack.

Notes

  • Sweet Potato Swap: Use regular sweet potato or pumpkin purée (not pumpkin pie mix) in place of Japanese sweet potato. Keep in mind these swaps will contain more moisture so you may need to adjust the flour. See my Healthy Pumpkin Muffins recipe for exact quantities.
  • Sweetener Options: Maple syrup adds a subtle caramel flavor, but honey or agave work just as well.
  • Flour Substitutions: Swap all-purpose flour with oat flour, almond flour, or a 1:1 gluten-free blend.
  • Milk Alternatives: Any dairy or non-dairy milk works here. Yogurt or applesauce also work.
  • Add Some Crunch: Fold in chopped nuts for texture and a boost of healthy fats.
  • Freezer Friendly: Freeze baked muffins for up to 2 months in a freezer-safe container or bag. Reheat in the oven or in the microwave in 30 second bursts.
