    These are amazing! I didn’t use as much sweet potatoes (I used 1 and a half). I also used coconut milk instead of the oil but they taste so yummy!!! I love how they are gluten free and wheat free, mostly because I’m coeliac and a health freak 😛 Deffo a must try for any choccy lovers out there.

    These are lovely! Substituted the coconut oil with some sunflower oil and they came out delicious. I will endeavour to find some coconut oil though, as I think they’d taste even better then!

      Hi Kristine! Thanks for letting me know- great to have an alternate option. My Protein sell coconut oil online if you’re interested! Nic x

    Loved the flavour of these (though might try without the cinnamon and add some chopped pecans next time) but they came out a bit flat! Should I have whisked the egg whites?! I can get LucyBee coconut oil in my local Sainsbury’s – my personal favourite is Viridian but it’s not so handy to buy.

      Hey! I bought the Groovy Food company coconut oil from Waitrose if that helps – £7 I think! Love idea of adding pecans. Mmmmm if they came out a little flat I suppose a little baking powder could help things. Do let me know if you try it – although brownies are meant to be quite compact! I hope this helps! Nic x

    OH. MY. GOD.

    Ok so you’re looking at the recipe and feeling a bit dubious about the use of Sweet Potato, don’t be. These are amazing! Moist, chewy, tasty and healthy too. Seriously, make a batch and you’ll agree!

    I can’t stop raving about these today, thank you Nic!!!

    Great recipe! Added raisons and chopped nuts to mine, also a little less chocolate and then saved some to put on the top. Shared a picture on twitter and Instagram today that looked delicious, in the hope others may copy the recipe! thanks again

    I don’t have a sweet tooth and rarely ever eat any desserts or chocolate but was really intrigued by these given the fact they had sweet potato in! I’m trying to get more calories in my diet and struggling to find decent snacks, well I think that problem is solved with these, they taste awesome!

    I’ve added cranberries to mine so far but will try other fruits and nuts and even tempted to see if chilli might work for a bit of a kick?

    This site is awesome Nichola and already proving a great resource for me as I love cooking and trying new things! Keep the recipies coming and keep sharing on twitter!

    • August 28, 2013 / 7:51 pm

      Thank you so much for your lovely message Dave – that really does mean a lot!! 🙂 I love your suggestion of chilli = and dried fruit! Coffee too would go good – ooh the options are endless. Thank you for your support!

    I made these last night, wow they are gorgeous! I made a brownie cake as I had left my baking tray in my mums house and it still turned out great. For the dark chocilate I used a few sqaures of the Green and Blacks Maya Gold which added a lovley warm spicy flavour. I also used drinking chocolate powder instead of the protein powder.
    Thank you so much for all your amazing recipe’s, my only trouble is what to try next!

    • September 17, 2013 / 4:36 pm

      Aw thank you Mandy!! I’l upload your fab pic too – love your idea of hot choc powder – I’ll add that into the recipe. Thank you!! Nic xx P.s can’t wait to see what you make next!! xx

    I made these this morning for the first time, I love the recipe and so simple to make. I’m a cakeaholic trying to give up, these make the perfect substitute. I can’t taste the sweet potato what so ever. I’ll be interested to see the difference in the chick pea ones. They’re next on the list along with the over night oats. Love this web sight. Going to make my way through each fab recipe. Keep them coming

      Aw thanks Rebecca! What a lovely comment! Thanks for your lovely pic too, I’ll be sure to upload it! Nic xx

    Hi Nic, have you tried freezing these brownies? I wonder if you could make in advance for Xmas? X

    • November 22, 2013 / 6:03 pm

      Hello! Yes I have.. why don’t you do a batch-free-defrost test to see?! They are so yummy you can have them guilt free before xmas too 🙂 xx

    Hi Nic, can I make these without egg white or is there an alternative?? I have issues with egg white, but am fine with egg yolks – would egg yolk be okay?
    Thanks for all the fab recipes x

    • December 20, 2013 / 9:48 pm

      Hello! Yes I’m sure egg yolk would be ok – or you could use chia seeds mixed with water for a ‘binding agent’! xx

    Hi Nic!
    Love these protein brownies, really want to try them!
    What whey powder do you recommend? What is better.. whey concentrate and whey isolate?

    Sorry for all the questions, just want to make sure I’m not putting anything into my body that it cannot digest easily!

    Thanks!
    P.S. I’ve just sent off my UCAS application to study Dietetics, hope i get in!! You are a great Dietitian role model for me, thanks 🙂

    • January 9, 2014 / 5:58 pm

      Aw thanks Zoe! I use Purition (whey), Sativa (plant protein) or MyProtein (whey) – there’s a full review under ‘reviews’ of Purition and Sativa plus a promo code so you know! xx
