Slimming World Chocoalte Brownie

1 Syn Chocolate Brownies

I’m a chocolate girl through and through, but when I saw that people were making Slimming World brownies I was pretty sceptical. How can you get decent brownies which are still good to eat on the Slimming World diet? Here’s how…

Well having looked at plenty of recipes and done some of my own testing I’ve come to the conclusion that you totally can! Many of the recipes that I’ve seen don’t have any flour in, but I have included a little bit to help give them the best rise possible but I’ve kept them very low syn! The flour is optional though, it makes the brownies bigger but less soft, personally I always go with bigger as it means they’re more filling and satisfying but it’s up to you! These brownies are a decent size but still only one syn per square, which is pretty epic in my books…you’re never going to get the gooey unhealthy effect that you do with regular brownies but if you’re looking for a chocolate fix then they’re incredible!

The perfect low syn chocolate fix you were looking for...

  • 30g Cocoa Powder
  • 35g Sweetener
  • 1tbsp Self Raising Four
  • 3 Eggs (separated)
  • 2tbsp Water


  1. Pre heat your oven to 180 degrees.
  2. Whisk the egg whites until they form soft peaks (you should be able to hold the bowl upside down without them falling out).
  3. In a separate bowl whisk together the egg yolks, sweetener, cocoa powder and water until they're smooth.
  4. Gently fold in the egg whites until they're all incorporated and then fold in the flour.
  5. Pour into pre-prepared container - I used quite a small deep one because I wanted thicker brownies but simply use a wider one if you're looking for a thinner brownie.
  6. Bake for 20 minutes.


If cut into 8 squares these brownies are 1 syn each on Slimming World (full batch = 8 syns)

    I tried these at the weekend. Lovely texture, nice rise, nice taste...until the hideous aftertaste I'd too much artificial sweetener hit. I never usually use artificial sweetener, but family do and agreed that there was too much. I used there a better one for this recipe? All of the SW brownie recipes I find say about the same amount of sweetener but none specify what type, and because I'm a novice with sweetener I have no idea of where to start to modify it myself! Or if I were doing these with sugar how much would I use? If I know that I can calculate how to use Sweet Freedom instead. Thanks!

      Hi Jo, thanks very much for your comment! Since making this recipe I have discovered Sukrin which is a brand of sweeteners that is seriously above and beyond everything else! They have the same texture and consistancy as normal sugar and they're substituted 1:1 which is really handy too (no more using an entire tub for one recipe!). They also don't have the nasty aftertaste either which is a big bonus!

    Hi Caliona, Do you used gold or white Sukrin for this? Just tried it with stevia and thought it was okay, after taste wasn’t too bad. Want to try with the Sukrin. Many thanks Lucy

      You could use either depending on the flavour you want Lucy, gold will give a more caramel flavour to it :)

    Could u use Belgian choc options instead of cocoa? If so how many syns would u suggest? Thanks
    1. Cliona

      22/01/2018 at 9:46 pm

      Yes you definitely could, you'd just need to adjust the syns by removing the cocoa syns and adding the choc shot ones!

    Made these and they lasted 2 minutes in my house. Very yummy. However, showed the recipe to my slimming world group and due to the sweetener now needing to be syned in cooking, they have advised that, to protect weight loss they should be syned at 4 per slice. Still super low for how they taste though and will be making them again ( this time I'll hide them though )
