Easy and tasty slice! Love this lemony goodness and delicious icing. Will be a favourite at our house for sure. Thanks Lauren x
Rebecca
Is this suitable for freezing?
Lauren Matheson
Hi Rebecca, yes it sure is 🙂
Danielle
Do you freeze before icing or does it freeze iced?
Lauren Matheson
You can freeze either before or after icing 🙂
Kay Carter
I make a similar receipe, but use orange rind in the mix and use butter, icing sugar and orange juice only for the icing. My family love it. I tried it with a lime once. Not as good but ok.
Sandra
Made this and the base is really wet .. I noticed this recipe has a lot more condensed milk than others. Are the quantities in this recipe right?
Lauren
Hi Sandra, Yes the quantities are right, I’ve always made this slice with a full can of condensed milk. The slice does firm up after it goes into the fridge, however if you are worried the mixture is too wet you could add a little extra coconut.
Sandra
Thanks Lauren .. Yes, it’s firmed up but still a bit raw tasting. I’ll try adding more coconut next time. Cheers

I want some of that lemon slice. I shouldn’t have clicked on your post since I’m doing this whole30 thing. It’s making me sweat …thanks a lot. HA!
Eva @ The Multitasking Mummy
I think one of my favourite slices would have to be a lemon slice and I’ve also discovered the Philadelphia Lemon Cream Cheese Icing which is great for a cooking cheat like me!
