What a shame I had to make these cookies for you this week 🙂 And I hate to say there are none left! Ooooops! But hey they are healthy right? These cookies are perfect to make with kiddos. Messy and sticky but tasty and healthy too. A great cookie that will keep for 5 days in an airtight container so one for the lunch box each day?

Anyone who knows me will realise I am a huge fan of peanut butter products (especially reece’s and M&M’s) but I don’t actually like peanut butter! Weird huh? But smother it in chocolate and I’m all yours!

Is this recipe Slimming World friendly?

As always I need to remind you that our recipes are unofficial and not checked by Slimming World. But here at fatgirlskinny towers we estimate these to be 6 Syns per cookie. 

Even though this recipe uses oats, I have not taken these from the Healthy Extra allowance because the mixture allows for 18 cookies.. I do not see you devouring 18 cookies in one day. (I would sure give it a good go though haha) 

TIP: If you purchase a “reduced fat peanut butter” available from some supermarkets, you can reduce the cookies to 5.5 Syns each.
