Super Simple Healthy Carrot Cake

If you’re a fan of baking but still want to slim down, no matter what lifestyle plan you’re following, it’s important to find recipes which fit within that whilst still giving you the same satisfaction of baking something delicious! This Healthy Carrot Cake is the perfect healthy bake…and it’s gluten free too!

How Is This Healthy Carrot Cake Gluten Free?

This healthy carrot cake is absolutely gluten free because it’s made with oats! You obviously have to ensure that you’re using oats which are marked as gluten free, some are made in factories so can be cross contaminated, but as long as you do that you’re set! Personally I’m not gluten intolerant but I love to make recipes which can be enjoyed by everyone and this is one of those bakes. You can find more of my gluten free recipes here.

How Many Syns in this Healthy Carrot Cake?

The beautiful thing about this cake is that you can have two slices (the cake is 10 slices in total) as your Healthy Extra B! If you ask me, having two thick slices of cake beats two small slices of wholemeal bread any day. Using two slices as your Healthy Extra B this cake is five servings.

Using your Healthy Extra B, the ENTIRE cake is JUST 9.5 SYNS including the icing! That’s UNDER ONE SYN PER SLICE!

How great is that though, you can have two big slices of this cake for your Healthy Extra B and one syn all in! If you decide not to use your Healthy Extra B you’ll have to count an extra six syns for the oats in the recipe per serving, but 7 syns for two slices of cake is still pretty great!

The icing on this cake is a cream cheese icing, made using a mix of Philadelphia Light and vanilla yogurt which works really well! What’s even better, if you needed another reason to make this cake, is it has carrot in which is speed food! Whilst I don’t think you could exactly say you’re eating this cake as the speed on your plate, it dramatically reduces the calories in the cake and ups the health and nutrient factors too.

Why Is The Sweetener Synned In This Recipe?

Under Slimming World’s recent changes granulated sweetener has to be synned if there is a tablespoon or more per serving in the recipe. It is synned at 0.5 syns per tablespoon, but if it’s in the recipe at less than a tablespoon per portion you aren’t required to syn it. This recipe contains five tablespoons of sweetener and has five servings so the sweetener is synned at half a syn per tablespoon, a total of 2.5 syns in total…still so much better than sugar!

          You could use any syn free vanilla flavoured yogurt :)

    This post had me scrambling over to Wikipedia to find out what Syns and Synning were! My husband adores carrot cake, but detests diets. What he doesn't know won't hurt him, eh? This sounds yummy, especially with that cream cheese icing!

      Thanks Michelle! It all sounds very complicated I know, but trust me it isn't! Slimming World is more like a lifestyle plan there's really no need to tell him ;)

        Thought blitzing oats would be a tweak ending up high syns ? ?
        1. Cliona

          21/04/2017 at 12:44 pm

          Hi Anne, tweaks only reference a free food being made into a non free food like flour. For example if this used quinoa as flour then that would be a tweak as you'd be in danger of overeating the quinoa and putting your weight loss at risk. With oats however you are either synning them or using it as your Healthy Extra B and therefore you are limited to the amount you can eat and therefore it isn't a tweak. If you don't use these as your Healthy Extra B then you have to syn the oats as oats, but if you are using your HexB then you can count the oats as syn free for that given quantity. Hope that helps!

    Carrot cake is one of my favorites. The restaurant that catered my wedding actually had a mostly guilt-free carrot cake using quinoa; it was easily the best carrot cake I've ever had in my life but have yet to replicate it. I'll have to try your cake in the meantime. :)

      23/03/2017 at 11:27 am

      I've not tried it with quinoa before but I have heard that it's lovely that way!

        Hi! Have made this recipe three times in the last two months... I make 12 cupcakes out of this mix, so I can just take one, and know my quantities. But I have two questions about alternatives. 1) Can I use liquid sweetener instead, and how much? 2) Is there an alternative to eggs? Thanks /H
        1. Cliona

          24/09/2020 at 1:25 pm

          Hi Henriette, I'm so glad you like the recipe! I think you could certainly use a liquid sweetener, but you would need to adjust the quantities based on whatever sweetener you were using. In terms of egg alternatives, I haven't tried it myself but I know people often use a flaxseed or chia seed mixture instead of eggs for vegan recipes. If you look up substitution quantities you should be able to find the information you need. I'm intrigued to hear how it goes!

    How many slices should it serve ?
    1. Cliona

      23/03/2017 at 11:25 am

      Hi Sue, the cake should be 10 slices which is 5 servings. Hope that helps!

        10/01/2018 at 8:57 pm

        At the top it says serves two?
        1. Cliona

          13/01/2018 at 10:29 am

          Each serving is two slices ?

    What temperature do you bake this cake
    1. Cliona

      It's baked at 180 degrees.

    I love carrot cake but I don't have a food processor. Would it work using a blender instead. Thanks
    1. Cliona

      24/03/2017 at 2:06 pm

      Hi Isabel, a blender would definitely work!
  • Emma Smith

    26/03/2017 at 4:03 am

    High Cliona, does turning the oats into a sort of flour increase syn value even more? Only my consultant says that once you alter the natural state if it, it has to be synned ?? I really want to try this recipe but am worried I may be having more syns than described :o/ thanks for your brilliant posts and site x
    1. Cliona

      27/03/2017 at 2:21 pm

      Hi Emma, don't worry! It's not a tweak if it's being used as your Healthy Extra B and if you're not using it as that you're synning it anyway so you're not in danger of overeating. A tweak only counts for free foods being used in a different way, for example if quinoa was being used as the flour, this would need to be synned as flour!
  • Michelle

    27/03/2017 at 3:37 pm

    I make the syns 26 for the whole cake (25g oats =4syns, Philadelphia light 25g=2syns)
    1. Cliona

      28/03/2017 at 1:56 pm

      Hi Michelle, as explained in the recipe the recipe the oats in this can be used as your Healthy Extra B or are synned.
  • Monika Dabrowski

    28/03/2017 at 5:22 pm

    This really is a healthy cake and it looks so beautiful too! I've never used sweetener instead of sugar, I must take a look at that section in the supermarket next time I go shopping.

    Made this cake today it looks great can't wait to try it. How long does the cake keep for? Do i need to store it in the fridge?
    1. Cliona

      11/04/2017 at 5:06 pm

      Enjoy! It lasts about 3-4 days. You don't need to sore it in the fridge :)
  • Lynbe

    14/04/2017 at 8:07 am

    I'm sure the syns are much higher than stated. The oats are 40g for your hex b then 7 syn s per 40g on top of that. Add the sweetener and it must be at least 30 syns for the whole cake.
    1. Cliona

      15/04/2017 at 11:20 am

      Hi Lynne, the syns stated are per slice not for the whole cake and also take into account using two slices as your HexB. If you do not do this then you have to syn the oats accordingly.
    2. Katy

      30/09/2017 at 12:34 pm

      I agree, the syns are very difficult to work out, especially as it says serves 2. Perhaps if the recipe said how many to cut it into to make it the HEB and 2 syns per serving then it would be easier to understand

    07/05/2017 at 5:40 pm

    Not on slimming world, could I use spelt flour instead of the oats?
    1. Cliona

      07/05/2017 at 11:56 pm

      Absolutely, it would work a treat! You may need to adjust the liquid slightly so maybe add gradually and mix until you get the right consistency!

        21/10/2020 at 6:35 pm

        Hi made 2 of these cakes lovely texture , but not at all sweet I’m using Betty winters granulated sweetener should this make a difference? It just needs to be sweeter Martin
        1. Cliona

          21/10/2020 at 7:47 pm

          Hi Martin, thanks for your comment. It may indeed be the kind of sweetener you're using, but I haven't used that specific brand before so I can't say for sure. You could try adding a bit more sweetener if you like, or maybe adding a natural sweetener like agave syrup for an extra sweet touch. If you do the latter though just make sure to account for it in the syn value if you're following Slimming World! All the best, Cliona

    Made this today came out fab. When I tasted it, it seemed salty ( no idea why) ! I stuck to all the ingredients x
    1. Cliona

      02/11/2018 at 4:27 pm

      Hi Claire, that's very odd. None of the ingredients are salty, so I can only imagine that maybe some salt has migrated its way into your sweetener, or maybe that the oats somehow have salt in? Otherwise I really can't imagine why! I'm very glad it came out well anyway, maybe put a big dollop of sweetened yogurt on if its a little salty for some reason?

    Made this cake today to take to a garden party and it was an absolute hit. Not a huge fan of sweetener, so I replaced the 5tbsp with 3tbsp of Honey instead, though I know I’ll need to adjust the syns per serving accordingly. This is definitely now my go-to Carrot Cake recipe.
