Nut Free and Grain Free Sweet Potato Healthy Brownies

These brownies are vegan, paleo, refined sugar-free, gluten-free, plant-based, nut free, grain free and oil free. That is a long list of diets but the main point is they are bursting with nutrition and are delicious.

It may look like a lot of ingredients but all the toppings are a case of just mixing or blending and you don’t have to use all four – just one or two are more than enough!

Ultimate Healthy Chocolate Brownie - Grain-Free

There are lots of sweet potato brownies out there but I have experimented to make one that is vegan, grain free, gluten free, nut free and full of nutrition from sunflower, chia, dates and buckwheat.

Buckwheat despite the confusing name is actually a gluten-free seed and nothing to do with wheat. It’s one of my staples on a healthy diet as it’s cheap, nutritious and very versatile.

One of my best recipes is for buckwheat bread that is naturally gluten-free. Buckwheat is often known as pseudocereal as it is used as a cereal or grain but isn’t one.

You can taste the brownie batter before you bake to check the sweetness – all the ingredients are safe to eat raw. If you wanted to have iced healthy brownies but are short of time just save one-third of the brownie batter mixture and blend it with a bit of water to make the frosting.

I thought about making the recipe just like this but this recipe to be popular the photos will need to have silky smooth icing and while using the mixture would still look good it will be as aesthetic.

Total Time 1 hour 10 minutes



  • 2 lb / 1kg Sweet potato

  • 1 cup / 175g Dates
  • 4 tbsp Cacao/Cocoa powder
  • 1 cup / 120g Buckwheat or Coconut Flour
  • 4 tbsp Maple/Coconut syrup, or similar
  • 3 tbsp Chia seeds
  • 9 tbsp Water
  • 2 tsp Cinnamon

  • 1 tbsp Cacao/Cocoa powder

  • 2 tbsp Coconut sugar
  • 6 tbsp Water


  1. Pre-heat oven to 180 C / 350 F.
  2. Bake the sweet potatoes for about half an hour until soft. Allow to cool then peel away the skin so you are left with just the flesh.
  3. Soak the chia seeds in 9 tbsp of water. Soak the sunflower seeds for at least 10 mins then rinse and drain.
  4. Place all of the brownie ingredients into a food processor for 2-3 mins until broken up.
  5. Pour the healthy chocolate brownie mixture into a tin lined with greaseproof paper. Use a large tin about 10″ by 6″, any will do but you may need to adjust the cooking times.
  6. Bake at 180 C / 350 F for 30-35 mins until when you stick in a fork it comes out clean. Leave to cool and firm up for 15 mins before taking out of the pan.
  7. Blend all the avocado frosting ingredients together, you may need to add a few tbsp of water.
  8. Whip the coconut milk for a minute to make the coconut whipped cream.
  9. Blend all the sunflower caramel ingredients together to make this nut free caramel sauce.
  10. Layer up the ultimate healthy chocolate brownie – brownie layer followed by avocado frosting, repeat this twice then top with coconut whipped cream and drizzle with chocolate sauce and sunflower seed caramel.
  11. It looks best with three layers of brownies, but it will self-destruct into a delicious mess when you attempt to tackle it!

Chocolate and chilli pair very well together and the Aztecs often enjoyed both together. This because chilli peppers contain capsaicin that releases endorphins and chocolate releases serotonin, the happy brain chemical. This combination together produces what is described as an extreme aphrodisiacal effect by the World of Chillies.

Don’t bin the sweet potato skins, instead bake them at low temp for a crispy delicious chefs treat! The skins of sweet potatoes are very nutritious. I always bake sweet potatoes whole as its quick, makes cooked sweet potato full of flavour and it’s easy to scoop out the orange flesh and enjoy the skins.

  1. This is amazing – I already have date caramel sauce and coconut whipped cream made in my refrigerator. These might have to happen before I run out! I eat dessert every night but this would almost require a special occasion to eat it just LOOKS like such a treat.

      Thanks Ashley, glad you like the recipe. I sometimes have this as a full meal, that in itself seems like a special occasion 🙂

  2. Hi Bastian, I am really wanting to try this but I can’t eat dried fruit (have to avoid sugar); could I replace the dates with more sweet potato? Or mashed chickpeas? Also, please can I double check that it is 1 cup coconut flour as I know that it is super absorbent compared to other flours
    Many thanks

      Hi Hen, You could add more sweet potato, however, it’s never going to get as sweet as it indented without any sugar. I wonder if things like birch sugar (xylitol) would work for you? Yes, that’s the amount but as with all my recipes its high in natural products so you may want to add a bit less if you think it’s too much – maybe 20% less? Cup sizes are US. Let me know how you get on 🙂

    1. Sure! I would use the drier prunes rather than the wet ones but honestly, the fruit is just there for sweetness. You may want to test it to check you’ve got the right sweetness for your tastes – it’s hard to say the right amount to use as there’s so much natural variation.

    1. I’ve got a ninja kitchen system at the moment, although I have broken the lid so need to hold it down at the moment. It’s good but i think it maybe trys to do too much. I really want to buy a magimix as hopefully that will last a long time, although I’ve been saying that since I moved house 5 years ago!

    1. Hi there, it’s per serving so 3 brownies with the fixings. Hope that helps and let me know if you try this healthy chocolate brownie!

  3. Hi! I soak and sprout my buckwheat. I am assuming i cannot just mix my sprouted buckwheat with all the other ingredients in food processor?

    Instead, would i have to dehydrate my sprouts and run through my flour mill?

    Hoping the first option would work.

    1. Hi Kelly,

      I usually try to use sprouted and dehydrated in this and do a big batch every month. However I think the first method should work so soak your buckwheat then leave somewhere to drain and dry as much as possible then just use in the recipe. It might take a bit longer to cook but I’m sure it will work just as well. Let me know how you get on.

    1. Hi Janet, its for a regular oven – but it’s just a very rough estimation as the size of the sweet potatoes will determine how long they need to bake more than anything else.

      1. Thanks.
        For anyone who does use a fan oven. The temperature adjustment is to use 160*c [if a recipe calls for 180*c]. This is more important for cooking the brownies to prevent burning.

        1. I’m so sorry I got my recipes mixed up this morning! I thought you were talking about the three ingredient brownies as had a comment before yours about that, in that one it really doesn’t matter as you are just cooking the potatoes before scooping out the flesh. For this recipe it does indeed matter!

          You are spot on, for a fan assisted do reduce by about 20C.

  4. Yummm!! Would love to eat the whole thing in one sitting but gotta savor! How long will the coconut whip cream and avocado sauce keep in the frigid?

  5. Hi Bastian,
    Thanks for sharing this recipe. It came out great but I struggled without a big enough food processor. How many cups in your processor? I am in the market for a new one and hope that I can make this again without having to do the processing in small batches!

    1. Hey there, I think mine does about 8 cups. A food processor is good but I find 95% of the time I just use a bullet one. But saying that I do live on my own.

    1. Bastian Durward

      I would use something like young coconut or anything fatty like cashew nuts to replace the avocado in the chocolate avocado frosting
