Marshmallow Crunch Traybake

Sometimes I wonder if many of these traybakes are just people taking the main ingredients in Fifteens and using them just a little bit differently, like in this Marshmallow Crunch Traybake. You have digestive biscuits, coconut, cherries and marshmallows, plus a few other standard baking ingredients.

Now, although this is called Marshmallow Crunch, it’s not actually all that crunchy. The base is a little crisp and the topping is sticky and gooey. Maybe, if you use a different sort of toffee it might come out a little crunchier, but whatever the case, it’s sticky and gooey and crisp and delicious! And not dissimilar to my Marshmallow Fudge Traybake, which is more caramel with a bit of marshmallow, rather than marshmallow with a bit of caramel – see, there are a lot of similar themes running through these recipes!

It’s all fairly straightforward to make too. The recipe calls for ‘soft toffees’ like Toffo. But my research seems to suggest that Toffos were discontinued some years ago, so that wasn’t going to work. I used Werther’s Chewy Caramels in my recipe, and anything like that will work here.

When you’re melting the butter and toffee together, they don’t really mix, so don’t worry if they’re separate. Once you add the marshmallows, it all comes together nicely into a sticky topping, that isn’t crazy difficult to spread over the base. Not totally easy either, but it gets there in the end!

2oz/55g brown sugar

    So I just made these today, after failing miserably at the topping of the Marshmallow Fudge Traybake last week (lol), and the base of this one came out super crumbly. Like, not really keeping together at all.
    Any advice on what to increase/decrease to get a base that stays together?

      It’s possibly down to the wet ingredient/dry ingredient mix. Maybe a bit more butter or a little less on the biscuit crumbs? Also, you can press it down quite firmly to help it come together in the tin.

        Thanks! I’ll try 1.5ing the wet ingredients, and maybe find a weight to squash the whole thing down with! lol
