Hi Lauren – thank you for the receipe. Made this last night and the mars mixture is really gooey! It hasnt set like your pocture. Where did I go wrong?
Lauren Matheson
Hi Angie, I’m sorry to hear this. How long did you leave it before cutting into pieces? I’m not sure what could have gone wrong, possibly the brand of rice bubbles might have made a difference? I’d suggest adding an extra mars bar and another 30g of butter next time to help it set. Merry Christmas xx

You can’t go wrong with Mars Bars!
Kim @ Land of Zonkt
Oh here too.
It truly is one of the easiest and most loved in this house.
I don’t have a thermi, but it still comes up pretty easy using the standard method I guess.
I’d love a thermi though, just for dinners and not having to think… also the custard is meant to be AMAZING
Lauren
It’s super easy no matter how you make them! I like ours as it makes dinner prep a lot easier, which is always a good thing! I haven’t made the custard in ages, thanks for inspiring me!
Lisa @ Chocolate Meets Strawberry
You had me at Mars Bar, Lauren! I am trying my best to avoid too much sugar at the moment, but I really do have a weak spot for Mars Bars and miss them! On the bright side of things, when I do eat one it means I really enjoy it! I can imagine these would be perfect for kids’ birthday parties. Who could possibly not love these delicious little slices of heaven?! 🙂
Lauren
That’s very true, when you don’t eat something a lot it’s all the more enjoyable – maybe I should try doing that 😉
