FAQs
Yes absolutely! Mix and match with any of your preferred jelly flavours. We have used strawberry jelly in this recipe as that's what is traditionally used.
Yes you do! If you pour the jelly onto the middle layer before it's set, the jelly will seep into the creamy filling rather than sitting in a nice layer on top.

Hi can I bake the base I think it would be nicer, 🌸
Lucy says
Hi Helen, we find that the best results are when the recipe is followed exactly 🙂
Shari says
This looks delicious - just wondering if I can double the recipe? I have a larger than normal slice tin so want to make sure the layers are nice and thick!
Lauren Matheson says
Hi Shari, I haven't actually tried to double this recipe before I'm afraid. I normally use a 28 x 18cm slice tin and it does make a big thick slice in that one if that helps 🙂
Felicity Oberg-Cooper says
Question for all you Jelly Slice lovers; can it be frozen? Doing school lunchbox mega cook to stock the freezer for the term and would love to include this. Thanks in advance.
Lauren Matheson says
I Felicity, I haven't tried to freeze this recipe before but I don't think it would freeze too well. Sorry xx
