Best Ever Lemon Coconut Slice!

I absolutely love lemon coconut slice. Like really, really love it! Each time I make it I seem to end up using a slightly different recipe… some have been good and others could best be described as crap! After the effort it takes to get the ingredients out and make a slice it is so annoying when the icing stays runny or the base crumbles!

Haha I love this quote!

So you can imagine how thrilled I was when I made lemon coconut slice (again!) this weekend and it seriously turned out the best ever!

Little slice of heaven!

The icing set hard (in fact maybe a little too hard… but more on that later!), and the base held together perfectly when it was cut! Best of all, it tasted awesome! And considering I had a tummy bug yesterday and my entire diet for the day consisted of toast for breakfast, chocolate cake (lol I thought I was starting to feel better… turns out I wasn’t!) for lunch and then toast for dinner, I was pretty excited to be feeling like eating real food again!


Anyway, back to the slice… I absolutely love lemons. I was one of those kids who would just happily suck on a lemon (yes I was a weird child!). I don’t do that anymore, but I am still a sucker for anything lemon flavoured! So I did change the recipe a bit to include extra lemon in both the base and the icing.

Condensed milk, lemon and butter… could life be any sweeter?

Well of course it could… just add biscuits and coconut!

A clever tip to get the base pressed down really hard is to roll a flat, round glass across the slice while pushing down. You could also use the bottom of a glass jar and press down.

Pile it in!

Press it down…

While the slice is in the fridge, make the icing in a saucepan. Beware! This icing sets so fast you literally need to pour it on and have a hot knife ready to spread it like a mad woman! Mine ending up setting a bit too quickly because I was icing the slice in in my PJ’s on a lazy morning and clearly my brain hadn’t quite woken up yet!

Mix icing sugar and lemon juice together over very low heat until smooth and warm

So if you feel like making a fool proof lemon coconut slice, then this one is for you! It went down a treat with a hot Milo, a movie and a lazy afternoon on the couch. Gotta love those days! Sweet, sweet laziness!

Morning! Just wanted to say I stumbled across this page yesterday while looking for a lemon slice recipe. Anyway, made it yesterday and if I didn’t have control of myself or my girls, it would have been eaten by yesterday arvo! Will be adding this to my go-to slice recipes. Also, as a tip for anyone else reading the recipe, wanted to say that with the icing setting so quickly, I filled a tall glass with hot water and put a couple of flat knives/spatulas in it to heat them, and this helped with smoothing out the icing once it… Read more »
