It is amazing that we can use sweet potatoes for desserts. The sweet potatoes replace sugar and also give chewiness and consistency to the desserts.
But this recipe is even more amazing, it has only 3 main ingredients, it’s vegan, gluten-free, and sugar-free. So, you should definitely try these 3-ingredient vegan sweet potato cookies.
This recipe is inspired by my other 3-ingredient cookies – oatmeal peanut butter banana cookies. I have just replaced the banana with the sweet potatoes. Also, the amount of oatmeal is different.
It is sometimes hard to eat a sweet potato on its own. But in a cookie form, it’s easy-peasy.
Especially when knowing the amount of micro and macronutrients of the sweet potatoes (they are so nutritious!).

What you need to know before making these vegan sweet potato cookies
- Make them crunchier! If you prefer crunchy over moist, after 10 minutes of baking the cookies, turn on the ventilation/fan mode of your oven. Bake them for 5 minutes on this mode.
- Is the batter too wet? Add a couple of tbsp more of oatmeal four/other gluten-free flour (rice flour, buckwheat flour, coconut flour).
- What kind of sweet potatoes to use? Doesn’t matter, as long as the potatoes are sweet!
- Add more nutrients! You can replace the pumpkin seeds with other highly nutritious ingredients, such as walnuts, almonds, sunflower seeds, pecans, or others.
- Don’t have enough mashed sweet potatoes? Add some mashed ripe banana or pumpkin puree. The batter might get too watery though, so add some more oatmeal flour into the batter.
- Allergy to peanut butter? Use seed butter instead!
- Make the cookies sweeter! Add up to ¼ cup of any liquid sweetener of your choice if you know that you like really sweet cookies (maple syrup, date syrup, agave syrup, honey)

Sweet potato cookies – ingredients
- Sweet potato. Use canned sweet potatoes, either bake them yourself. The color of them doesn’t matter, as long as they are called sweet potatoes. The sweet potatoes will give the cookies sweetness and will make them moist and chewy.
- Oatmeal. This ingredient replaces regular flour in the recipe. It’s gluten-free and very nutritious. If you have oatmeal flour, it’s even better. Just omit the blending part of the old-fashioned rolled oats and use the same amount of oatmeal flour.
- Peanut butter. This butter is a nice replacement to the regular butter, or to the oil. Actually, that is why we are using it. Also, peanut butter gives a nice aftertaste and aroma to the cookies. But feel free to replace it with other nuts/seed butter of your choice.
- Pumpkin seeds. This is an optional ingredient. It is added because it is healthy and nutritious. However, you can replace the pumpkin seeds with other seeds like sunflower seeds; or with nuts such as walnuts, pecans, chopped almonds. Or you can just stick to the main 3 ingredients of the cookies.

How to make vegan sweet potato cookies?
- Bake the sweet potatoes. Firstly, using a fork or knife, make some holes in the sweet potatoes. Then, in a preheated to 200 C/400 F oven, bake them for about an hour.
- Mash them. Next, let them cool. Remove the skin when cooled and mash them with a fork.
- Blend the oats. Add into a food processor the old-fashioned rolled oats and blend until you obtain a flour-like consistency.
- Combine the ingredients. Into a mixing bowl, add the oatmeal flour, mashed sweet potatoes, peanut butter, and (optional) the pumpkin seeds.
- Mix. Using a spatula, mix the ingredients until they are well combined. Optionally, add some sweetener to the batter (maple syrup, honey) to make the cookies sweeter.
- Shape the cookies. Take around 2 tbsp of batter and form a cookie out of the batter. The cookies don’t spread in the oven, so you can leave very little space between them. Then, using a form, press on the cookies to make them look cool and to make the outside of the cookie crunchier.
- Bake them. Into a preheated to 175 C/350 F oven, place the cookies and let them bake for about 15 minutes.
- Let them cool. After removing them from the oven, place them on a cooling rack and let cool for about 10 minutes before serving.
- Enjoy!
