Waffles are a brunch staple and kid-favorite breakfast food. These sweet potato waffles make it easy to sneak in veggies, while also boosting your daily vitamin A and fiber intake. Another bonus is they’re naturally gluten-free since they’re made with oat flour. This recipe is a great way to use up plain, leftover roasted or mashed sweet potatoes, but don’t let a lack of leftovers stop you from making them. They're worth cooking a sweet potato or two.

Most waffle irons have a handy light that goes on or off, signaling the waffles are ready, but don’t rely on them solely or else you risk over- or under-done waffles. A sure sign of doneness: The steam stops shooting out the sides of the waffle maker.


  • 1 1/2 cups oat flour
  • 1 tablespoon baking powder
  • 1/4 teaspoon salt
  • 1 cup sweet potatoes (cooked, cooled and mashed)
  • 2 large eggs
  • 2/3 cup milk
  • 6 tablespoon butter (melted)
  • 1 teaspoon vanilla extract

Steps to Make It

  3. Pour the milk mixture over the oat flour mixture and stir with a fork until just combined. Let sit for five minutes. This resting time allows the baking powder to activate.

  4. Meanwhile, heat your waffle iron. Pour or ladle enough batter to cover about 2/3 of the surface (the rest will spread once you close the top). Close and cook according to the waffle iron manufacturer’s instructions.

  • If you don't have leftover sweet potatoes, cook them until tender, then mash them. Scrub the potatoes, poke them with a fork a few times, then bake in a preheated 425 F oven until tender when pierced with a fork, about 45 minutes. Alternatively, you can cook them in the microwave for about 5 minutes on high power, depending on the size of your potatoes and your microwave's wattage.
  • If you can’t find oat flour or want to save some money, you can easily make it at home. Just add whole, old-fashioned oats (not quick-cooking) to the bowl of a food processor and pulse until they’re ground into a fine flour. 

Recipe Variations

  • To make this recipe dairy-free, just swap in your favorite unflavored, unsweetened milk alternative, and use a neutral oil, like sunflower or grapeseed, in place of the melted butter.
  • Can you use canned sweet potatoes? Yes! As long as they’re unseasoned and plain, you can use cooked, canned sweet potatoes. Even frozen sweet potatoes steamed or cooked in the microwave will work. The key is to make sure the sweet potatoes are plain and not seasoned with any spices or other ingredients.
  • Spice it up! We wanted to let the sweet potatoes shine in this waffle recipe. Feel free to spice up your breakfast by adding 1/4 to 1/2 teaspoon cinnamon, allspice, or even pumpkin spice.
