Healthy sweet potato brownies made with wholesome ingredients are fudgy, rich and lightly sweetened with pure maple syrup. These vegan brownie bites also have cute google-y eyes inspired by soot spirits in Totoro! The perfect quick and easy Halloween treat. (Vegan + Gluten Free)
With most of us spending Halloween indoors this year, homemade Halloween treats is what we all need. Eric and I made these spooky cute mini two bite brownies on a whim based off of my favourite pumpkin brownies and they came out so delicious that I wanted to share this last minute quick and easy halloween treat!
What are soot spirit brownies?
If you've watched Totoro or Spirited Away from Studio Ghibili Films, then you're probably familiar with the cute lil' soot sprites. If you're unfamiliar, they're these little round fuzzy dust bunnies with big round eyes. Wanting a Halloween treat that was easy to make, brownies were an obvious choice because... chocolate! Plus, they come out of the pan round so no shaping required.
PS. Both Totoro and Spirited Away are the perfect movies to watch on Halloween. Kid friendly, cute but also spooky with a creepy store behind the movies.
How to Make Sweet Potato Brownie Bites
The Ingredients (+ substitutions)
These healthy brownie bites are made with wholesome ingredients AND contain hidden veggies. Plus, they're vegan, gluten free, oil free, refined sugar free and nut-free so everyone can enjoy!
- Flax egg: made by stirring 1 tablespoon of flax and 2 table spoons of water and letting it rest for 5 minutes.
- Sweet potato: either steamed or baked.
- Sunflower butter: these brownies are nut-free but you can also use any nut butter of your choice.
- Maple syrup: keepin' these healthy brownies naturally sweetened! You can also use agave or coconut sugar but you may need to add 1-2 tablespoon of non-dairy milk to compensate the wet ingredients.
- Vanilla: for flavour.
- Cocoa powder: use good quality cocoa powder for best results. I use unsweetened dutch processed cocoa powder which is darker (perfect for these soot spirits) but also more mild in bitterness.
- Oat flour: I've only tested these with oat flour but gluten free all purpose, spelt flour or all purpose flour should work as well. For a paleo version, substitute with 2 tablespoon coconut flour.
- Candy eyes: For the soot spirits! I made my own with vegan powdered sugar but you can also purchase them.
These have no chocolate chips added to them but you can totally add some.
These sweet potato brownies are incredibly easy to make in just a food processor:
- Process all the ingredients together until smooth.
- Transfer to mini brownie cups.
- Bake for 12-15 minutes at 350 F.
And then once cooled, just decorate them with the candy eyes.
BOOM. Perfect fudgy rich veggie hidden chocoalte-y goodness-- thats also super cute and spooky.
Can I make these without a food processor?
Yes! Just mash the sweet potato well until its smooth. Whisk the wet ingredients together and then add in the dry. Then bake as instructed.
Tips for Brownie Bites
- Non-stick mini muffin tin: Use a good non-stick muffin tin to remove the brownies easily. I still do highly recommend greasing the pan just a bit to ensure they don't break when taking them out.
- High quality cocoa powder: Use dutch processed cocoa powder for tastier brownies, especially if you're not adding chocolate. They're less acidic but have a rich flavour.
- Baking time: Mini brownies bake up quick. Keep an eye on them at about the 12 minute mark. If unsure, pull them out early rather than over baking.
- Let the brownies cool: These brownies need time to set or they'll be difficult to remove from the pan, fall apart and be too fudgy. Letting them cool will also intensify their rich chocolate-y flavour. Plus, if you add the eyes they will melt if you add them while they're still warm. If you prefer eating your brownies warm, microwave for about 5-10 seconds and enjoy!
Storing & Freezing Brownie Bites
These bites are best eaten within a day or two of making. Keep in a airtight container at room temperature for up to 2 days or refrigerate for up to 4 days. These also freeze beautifully and will keep for up to 1 month. When ready, just thaw at room temperature or microwave them for about 15 seconds (or until warm) with a damp paper towel covering it.
Happy halloween, friends!

The best mini muffin pan, it's so good for small batch baking! I hope you enjoyed 🙂
So cute and yummy! I made these with my little ones today and we devoured them. I like that they're really chocolatey and not overly sweet. I'll have to make sure I have some little eyes on hand for next time we watch Spirited Away or Totoro!
I love these!! I make them all the time when I’m wanting something kinda sweet that doesn’t leave me feeling gross! It’s dense, chewy, and superr fudgy. Love them to death lol.

Happy to hear you enjoyed, Katie!

Super easy and yummy! I used rice flour instead of oat flour. Because of that I needed more liquid and I used about 70ml soy milk. The brownies took 30 minutes to bake and they came out absolutely delicious!
I'm sadly not the owner of a food processor or a mini muffin pan, but I mashed my sweet potato on a plate and baked this in a 9x4 inch loaf pan and it came out perfectly! So delicious and probably going to be my go-to brownie recipe from now on because they are perfectly fudgy and not overly sweet
