Delicious, Healthier Blondies with Sweet Potato

Do your kids enjoy sweet potato? Mr 3 is a sweet potato fiend. It’s one of his favourites. Miss 3 doesn’t mind them either. But Mr 7 has not had a piece of sweet potato between his lips since I don’t even know when. But you know what? When I offered him a slice of this Healthy Sweet Potato Blondie, he didn’t hesitate. And he adored them. And I feel like that is even an understatement. He loved them. Luuuurrvvved them.

And I do too. These Healthy Sweet Potato Blondies are all kinds of amazing. This healthy blondie recipe tastes quite sweet but they’re actually comparatively low in added sugar.

There is only a small amount of maple syrup and white chocolate chips added to this recipe – 1/3 cup of each and it’s largely sweetened by the sweet potato. This is a huge reduction in sugar compared to some recipes that can have up to 2 cups of white sugar and 1 1/2 cups of white chocolate. And none of the nutritional benefits of the added sweet potato.

I love to add veggies to baking to give it that extra boost and I love the extra fibre and vitamin c the sweet potato brings to these Healthy Sweet Potato Blondies.

This moist and soft healthy blondies recipe comes together pretty quickly too and the recipe is simple enough to make this with your kids. The twins loved helping to make this, especially being quality control for the white chocolate. I especially think it’s important to let your kids get in on the baking action when you are baking with vegetables to normalise the different ways of enjoying vegetables.

These delicious Healthy Sweet Potato Blondies are a healthier take on blondies. Lower in added sugar, made with wholemeal flour and a generous serve of sweet potato, these blondies are a must bake.


  • 1 cup mashed sweet potato (250g raw) – see note
  • 125g butter melted
  • 1/3 cup maple syrup
  • 2 eggs
  • 2 tsp vanilla extract
  • 1/3 cup white chocolate chips (50g)
  • 1 1/4 cup plain wholemeal flour (150g)
  • 1/4 tsp baking powder


  1. Prepare your sweet potato and set aside to cool (see note)
  2. Preheat your oven to 175c and grease and line a 27.5cm x 17.5cm x 3.5cm slice pan
  3. Melt the butter in the microwave and allow to cool slightly
  4. In a large bowl whisk together the sweet potato, butter, maple syrup, vanilla and eggs and whisk thoroughly together
  5. Add in the white chocolate chips and then fold through the flour and baking powder until just combined
  6. Spread into the prepared slice pan and bake at 175c for around 15 minutes or until the brownie is just cooked through and the top bounces back when lightly touched and a skewer inserted comes out mostly clean
  7. Allow to cool in the pan before removing and cutting into 16 portions


To make the sweet potato, boil in as little water as possible for around 15 minutes until soft and cooked through but not overly mushy. Drain any remaining water then mash the sweet potato and set aside to cool before making the blondies.

I hope you love these Healthy Sweet Potato Blondies as much as we do. Remember to get social with me – take a pic with your baked goodies and share with my on Instagram or Facebook.

Happy baking,

  1. Hello,

    We need to avoid dairy and can sub butter for Nuttelex but wondering what you’d recommend as a substitute for the white chocolate chips? Would raspberries work do you think?

    • Sorry for the very delayed response. I would go for a dairy free chocolate chip rather than raspberries. Or raisins might work too? Bernadette x

  2. These look great, what could I substitute the butter for? (my son is dairy intolerant) perhaps oil? or would nutellex also work?

  3. made a batch of these delicious blondies and they were so yummy and easy to make plus freezer friendly for lunchboxes, thank you for the great recipe bernadette!

  4. Hi, How do you store these? Can they be frozen?

    • Hello, I freeze these after they have been portioned in an airtight container. I separate layers with baking paper if stacking. Bernadette x

  5. Here in my poorly stocked corona isolation kitchen, I substituted roasted oat flour and my maple syrup ran out halfway so I substituted the rest with honey. It came out absolutely brilliantly! The crumb was extremely tender and the flavor wonderful. I’m going to just keep making them this way in the future. Thanks for the lovely recipe.

  6. Delicious!! I substituted maple syrup for rice malt syrup as i didn’t have enough maple. My husband has no idea these Blondies have sweet potato in them 😂 Hopefully they will be a hit in my fussy 4 year olds kindy lunchbox tomorrow too! 🤞

  7. omg, soooooooo gooooooood! should have baked a double batch

  8. Kristy Staples

    Yummy, this is delicious!

  9. Charlotte

    I’ve just made these and they are amazing thank you so much for the recipe! Please can I ask how you store them? I think I might try freezing them so I don’t eat them all in one go and I have them for a quick snack for my toddler? x

  10. Jodie Nixon

    Can I use golden syrup instead of maple syrup?

    • Bernadette

      I have not tried – I would say you could, I think it would be a bit sweeter so you may want to reduce the amount a little. Bernadette x

  11. These were awesome thanks so much my kids and hubby loved them!!!

  12. Just made a batch today and OMG, yum!! Super easy and great as a treat in the lunchbox.

  13. Hi, what else could I use instead of the plain wholemeal flour? Would self raising or plain flour work? Thanks heaps!

  14. Amanda Tong

    Hi lovely lady,
    Do you think it would work out OK egg free?

    • Bernadette

      I haven’t tried but I would think it would work. It may be more chewy. Let me know how you go! Bernadette x

  15. Love your blog :D. I have a question, what can I use instead of the white chocolate chips? Thank you very much!

    • Bernadette

      Thank you! Maybe just dark chocolate chips, or are you looking to avoid the chocolate? Bernadette x

      • Hiya this rec looks amazing ..just one question can I substitute the white flour to anything more healthier or mayb gluten free ..thanks

        • This recipe calls for wholewheat or wholemeal flour so this flour has more fibre than white flour. Unless you have allergies, intolerances or are coeliac gluten free flour offers no more health benefits than wheat flour. Thanks Bernadette.

  16. Is it ok to double this recipe please? Thinking it would make a great snack for the kids at daycare!
