Seriously Easy Syn Free No Bake Berry Cheesecake

I’m talking creamy, soft, delicious, cream cheese-y, cheesecake, not wobbly jelly on a dry base which unfortunately is often the way that Slimming World cheesecake go!

I made this completely Syn Free Cheesecake for my taster evening at Slimming World this week, and I have to say it went down really well…I was even surprised at how delicious it was and I made it! Obviously when I say syn free it doesn’t come without a little caveat, which is that per slice you use your Healthy Extra B and just a third of your Healthy Extra A…but that’s a very small price to pay for a proper cheesecake!

I’m not sure I can stress enough that this isn’t jelly on a cheesecake base, which frankly my last cheesecake was, this is made with cream cheese and quark (which you can’t taste I promise!). Regular full fat cheesecake is made with cream cheese and cream, so this is probably about as close as you’re going to get, unless some genius invents fat free cream some time soon! 

DSC01027 (2)

Cheesecake is something which has taken a long time to creep up on me to be honest, and for most of my life I couldn’t eat it because to be honest the words ‘cheese’ and ‘cake’ sounded disgusting together. It wasn’t until I tried cream cheese icing for the first time (YUM!) that I realised I was being a moron and it wasn’t like my cake was about to be filled with Stilton! 

DSC01018 (2)

Another exciting discovery that I made, which lead to the inception of this delicious cheesecake recipe, was that Sukrin do an icing sugar sweetener (buy it here)! This means it’s completely syn free, and removes the need for pots and pots of Muller Light, and completely changes the dynamic of the recipe.

Instead of needing tonnes of gelatin to stabilise a liquid mess, you just need enough to set the two kinds of cream cheese (Lightest Philadelphia and Fat Free Quark) which is the reason you’re not left with jelly! Rather, you end up with a creamy layer of yumminess, that your spoon slides through like butter and completely melts in the mouth! Deeee….licious! 

DSC01021 (2)

I’ve made the base here out of the Special K Chewy Delight Bars which can be used as your Healthy Extra B, but you could equally use HiFi bars or another sticky Healthy Extra B bar of your choice. The key is that when they’re melted they’re still sticky because this removes the need to add extra butter and makes the base syn free when using it as your Healthy Extra B choice.

New Updated Information: 

In accordance with Slimming World’s new rules the following information has changed: 

  • Philadelphia Lightest is no longer classed as a Healthy Extra A. Recipe calls for 360g which now equals 14 syns. 
  • Sweetener is now synned at 1/2syn per tablespoon. 200g Sukrin equals approximately 10tbsp which now equates to 5 syns. 

Therefore, this recipe no longer counts as your Healthy Extra A and counts as just under 2 syns per slice plus your Healthy Extra A! Still pretty great fora proper cheesecake!

5 based on 1 review(s)


  • 2x 180g Pots Philadelphia Lightest
  • 1x 250g Pot Fat Free Quark
  • 1x 200g Pack of Sukrin Melis Icing Sugar
  • 1.5x Packet of Powdered Gelatin
  • 50mls Boiling Water
  • 2tsp Vanilla Extract
  • 10x Special K Chewy Delight Bars (Healthy Extra B - or use equivalent HexB bar)
  • 1x Punnet Raspberries
  • 1x Punnet Strawberries


  1. Break up the cereal bars in to a microwave proof bowl, and microwave for 30 seconds until they're soft and falling apart.
  2. Tip these into a round spring form cake tin (with a removable base) and press down to form a consistent base using your fingers and a spoon. Place in the fridge to cool and harden.
  3. Dissolve your gelatin in the boiling water completely and let cool.
  4. Tip the Philadelphia Lightest, Quark, Icing Sugar, Gelatin and Vanilla Extract into a large mixing bowl and whisk together either using an electric whisk or a hand whisk.
  5. Chop half of the fruit into small pieces and stir these into the mixture.
  6. Remove your base from the fridge, line with halved strawberries (with the chopped middle facing outwards and pressing against the side of the cake tin).
  7. Pour in your cheesecake mix onto the base, cover with cling film and place on a level shelf in the fridge to set overnight.
  8. Just before you're ready to eat the cheesecake, remove it from the fridge and top with the rest of the fresh fruit. Drizzle with Choc Shot if you want (add syns depending on how much you use).
  9. Serve immediately, it won't last long!


One Special K Chewy Delight Bar is classed as your Healthy Extra B choice, so sliced into ten slices this recipe equals one portion per slice.

      how is it syn free with icing sugar
      1. Cliona

        27/06/2016 at 7:03 am

        Hi Sheila, the Sukrin Melis Icing Sugar is a sweetener so is completely Syn free! Hope that helps, Cliona.
        1. Sally

          20/06/2017 at 1:59 pm

          That icing sugar seems to cost thirty quid for 200g- seriously?
          1. Cliona

            01/07/2017 at 10:23 am

            Sometimes on Amazon they sell out and the price gets hiked up! You can usually find it on Holland & Barrett for cheaper :)
          2. Joy

            05/08/2017 at 8:21 am

            It's also now syned if you use more than a teaspoon per portion - 1 tablespoon = 0.5 syns like all other sweetener granules and powders
      2. sheila ingram

        27/06/2016 at 7:14 am

        ok, but what about the chocolate
        1. Cliona

          27/06/2016 at 7:16 am

          The chocolate is just a topping, you'll see in the recipe it's noted as an addition with syns ?

        sorry, i have to complain again, but you do realise vanilla extract isnt free @?
        1. Cliona

          28/06/2016 at 9:03 am

          Hi Sheila, I'm afraid that's not correct. All flavourings, food colourings and essences are Syn free. Thanks for your comment though. Cliona

    Is there a substitute for the Sukrin Melis icing sugar I can use? Tia Paul
    1. Cliona

      22/06/2016 at 7:26 am

      Hi Paul, as far as I'm aware there isn't another icing sugar sweetener, but you may find one if you have a really thorough Google. I wouldn't try just regular sweetener as I don't think you would get the same result, is there a reason you don't want to use the Sukrin one? Let me know and perhaps I can suggest a more helpful answer! Thank you, Cliona

        28/10/2016 at 10:05 am

        Hi I am trying this tonight but can't get the icing sugar in big supermarket. ...what is its function in the recipie is it to sweeten or to aid with setting?
        1. Cliona

          28/10/2016 at 10:07 am

          Fantastic! It's to sweeten and I know lots of people have had great results with regular sweetener so you can definitely give that a go instead! Just sweeten to your taste ?
      2. Paula Marsh

        05/02/2019 at 9:31 pm

        Yes there is I bought the PINK SUN Erythritol Sweetener Powdered 1kg (or 2kg 3kg 5kg) Fine Powder Natural Icing Sugar Replacement Zero Calories Non GMO, sin free and only £8 for 1kg and I only needed 100g

    This looks absolutely gorgeous and would make a lovely dessert for an "occasion". Can't wait to try it! Where do you buy Sukrin Melis? I've never heard of it, let alone seen it in Sainsbury's. Also Choc Shot. HELP!
    1. Cliona

      22/06/2016 at 1:34 pm

      Thank you very much Janine! It's a bit of a pain but I don't think you can get the Sukrin Icing Sugar in stores, I got mine on Amazon when I discovered it existed! There is a link in the text of the post to take you to the page on Amazon. I think you can also get it on Muscle Foods which is great, but you would obviously have to order past their £25 minimum so it's a good place to get it when you're doing a meat shop with them (if you do, they're amazing!). Choc Shot is however very available in stores, it's usually somewhere near the hot chocolate! Thanks for commenting!

    The gelatin has gone lumpy in the cheese help ?
    1. Cliona

      25/06/2016 at 1:28 pm

      Hi Caroline, so sorry to hear that! Did you use powdered gelatin like in the recipe? You have to completely dissolve it in water before adding it to the cheese. Hope that helps? X
      1. Stacey Sage

        06/01/2017 at 2:08 pm

        Hi Cliona, your recipe says 50mls of water is this correct, only the gelatine pack says each pack makes 1 pint of water & that you should add much more water than 50 mls, I have just made this cheese cake & the gelatine went into a complete lump just like Carolines did so now I have a cheese cake without the gelatine ahhh ! is it likely to set at all ? please can you reply asap - Thanks
        1. Cliona

          06/01/2017 at 2:13 pm

          Hi Stacey, thanks for commenting. Did you use boiling water? If it isn't dissolving then pop the gelatin with a little more boiling water (another 50mls) in the microwave for 10/20 seconds and that should do it ? Hope that helps!
          1. Stacey Sage

            06/01/2017 at 2:23 pm

            yes it all dissolved no problem, the problem occurred when I added it to the cheese mixture ? it pretty much set straight away which is what makes me think the gelatine should have been added to much more water than 50 mls ?
  • Caroline

    26/06/2016 at 11:19 am

    Hi yes I did - I sieved the cheese mix to get rid of the lumps and then added that to more dissolved gelatine, it is slightly jelly looking bit ill give it a try - it doesn't look beautiful like yours! Xx
    1. Cliona

      26/06/2016 at 11:50 am

      How strange I've never had that problem! Glad it has turned out OK, I'm sure it'll be tasty especially with all is the hard work you've put in! Xx
    2. Cliona

      06/01/2017 at 2:34 pm

      I'm sure it looks lovely! I've never had that issue with the gelatine, so I'm not 100% sure what to suggest as it always stirs in perfectly for me! If you make it again maybe use 100mls first, also allow it to cool slightly before adding incase the sudden hot to cold makes it lumpy (the only think I can think of!) hope you enjoy it! ?
  • Janine Lawrence

    27/06/2016 at 6:54 am

    I made it yesterday and IT IS absolutely gorgeous! I wasn't able to wait for the Sukrin order, so decided to take the bull by the horns and use granulated sweetener (mine is from Lidl and is called Cologran, the one with the yellow lid). It works perfectly well, in fact you just wouldn't know. I didn't weigh it as it's so light, but added it by taste. In other words, once it was sweet enough for me I stopped adding it! This cheesecake is seriously lovely and looks great too! I've added a photo of it to my SW group Facebook page and there have been lots of admiring comments! Well done on creaing this, Cliona. This will be a staple on my dessert menu,
    1. Cliona

    Hi I'm confused as Philadelphia lightest is synned according to my slimming world so how is it free? Am I not finding the right Philadelphia ? Thanks
    1. Cliona

      28/06/2016 at 6:43 am

      Hi Dee, have you read the recipe? Philadelphia Lightest can be used as your healthy extra a option and therefore per slice you are using 1/3 of that which makes this Syn free as mentioned a few times above. If you aren't using it as such though yes you would have to Syn it. I hope that helps! Cliona

    29/06/2016 at 7:04 pm

    Where can you get powdered gelatin from and exactly how much is used in the recipe as it says 1.5 packet but no size for the packet. I would love to try the recipe so please help.
    1. Cliona

      29/06/2016 at 8:12 pm

      Hi Carolin, you can get the packs from most supermarkets. They're 12g each ?

    1. Cliona

      02/07/2016 at 9:05 am

      Hi Anne, thanks so much for commenting! Quark is a type of cream cheese, but it tastes and looks a bit more like a thick yoghurt. On its own it's quite tasteless however it's a fabulous healthy cooking ingredient! I use it for loads of things!

    Ive have just made this but my geletin went all lumpy too so had to take some out any ideas how to solve this problem for next time plz
    1. Cliona

      04/07/2016 at 8:30 pm

      Hi Karen, did you mix the gelatin with the water until it was completely smooth? If so it shouldn't have gone lumpy. However perhaps try adding 20/30mls more boiling water next time, it might make a difference! Hope that helps!
  • Vanessa

    05/07/2016 at 9:07 pm

    1. Cliona

      Hi Vanessa, I used a 20cm tin but depending on how thick you wanted it you could use a bigger one or a smaller one!

    Can you suggest a vegetarian way of making it? i.e no gelatine? Or alternatives and amounts?
    1. Cliona

      05/07/2016 at 10:54 pm

      Hi Rags, I haven't tried it in a vegetarian way however I know that you can buy veggie gelatin which I presume would just be used in the same way! If you get some it should tell you how to substitute it on the packaging. Hope that helps!

      Hi Heidi, there aren't any other icing sugar sweeteners, I do know that people have tried it with regular granulated sweetener and it works but it's not quite as nice. You can buy Sukrin through the link in the post on Amazon or on Muscle Foods ? hope that helps!

          05/09/2016 at 9:00 am

          Hi Elizabeth, the Sukrin sweeteners are sold out in a lot of places right now unfortunately which has driven up the price of the ones on Amazon super high! They have let me know that they'll be getting more in soon though so this price should go down very soon! Last time I ordered it it was about £4 a pack so it will go down!

    Hello, this is a wonderful cheesecake o thanks for that. I actually bought two tubs of quark by mistake and only 1 tub of Philly and it worked out just fine too. I also substituted the icing sugar for sweetener and put in frozen strawberries and raspberries (defrosted)and mixed it up. It was super delicious so thanks for that.

    07/12/2016 at 8:07 am

    Unfortunately sweetener is now 1/2 syn per tbsp :( . Do u use the full 200g of sukrin?
    1. Cliona

      07/12/2016 at 9:38 am

      Hi Tanya, I wrote this recipe long before Slimming World decided to syn sweetener, however in posts since I have talked about how personally I don't do this. As your limited to one slice because of your Healthy Extras you can only have a limited amount of this cheesecake, unlike for instance the 1/2 syn cake which you could eat the entirety of. I have lost almost four stone without synning sweetener as have many people before me so it's just not something that I'm going to do. However if you prefer to do so then you can of course syn the sweetener in this cheesecake to protect your own weight loss journey. Hope that helps!

    Yummers. Made this yesterday so nice. I couldn't find the special k bars so used 10 Aldi Benefit Light Summer Berry bars (2 are a hexb), i'm also new to slimming world so i synned the sweetner (75g) synning the bars, philly and sweetner it works out at 6syns a slice (10 portions) but I don't know how many syns it would be if I used my hexb and hexa daily allowance for a slice too. Can you help? It would be easy if the bars were 1 for hexb like your recipe but there 2. Sorry for being a pain i just can't get my head around it.

    Where the heck are "Special K Chewy Delight Bars " or any other "extraB" bars, which are loaded with nothing but shit, syn free? Since when are low fat products (processed foods) syn free? Icing sugar + Gelatin (made of animal fats) syn free? This is wrong education at it's finest. If you want a real syn free cake you take avocados, honey/maple syrup and cocoa powder/dark chocolate +nuts and oats and other RAW INGREDIENTS but not bars from Kelloggs, one of the worst brands on this planet
    1. Cliona

      23/05/2018 at 11:01 am

      Hi Patrick, thank you for your comment. I would urge you to look more closely at this site, as many of these recipes are geared specifically towards people following the Slimming World plan. I think you are confusing the term 'syn', which is specific to Slimming World, with the concept of 'clean eating' which this site doesn't pretend to be.
