I made this last night and it is a hit!
I had to use nearly a whole pack of marshmallows to get pretty good coverage, so maybe my slice tin was a bit bigger than it should have been. The slice base isn't crumbly though -maybe thinner works better? I did press down pretty firmly, and had also mixed it longer than the recipe stated until the base dough was coming together (was still very floury/dry after the time in the recipe), if that makes a difference.
It's a good thing I am taking most of it to an afternoon tea today as it is far too delicious!
Ah maybe that is the thing - mix it longer! I always mix cakes a lot less than the recipe says as I think the TM beats the poor things to death! This one obviously needs a good flogging!!
Will try that next time.
In the essence of research and development (and scoffing ourselves silly on yet another batch of wagon wheel slice
) Miss 17 made it again yesterday. Only problem was Miss 17 and I
ate sampled tested a couple too many marshmallows and there wasn't quite enough to go right over the top
... you do need to use more than half a packet if you want them touching side by side
Tip** don't test the marshmallows, you do need a fair few!
The base is still a bit crumbly and I cooked it 5 minutes less at the start, so will try jo's tip above.
I'd love to post a photo but it seems it's not only the marshies that have been well sampled!
