The easiest and most delicious baked Lemon Slice ever…. with the BEST creamy & tangy lemon frosting – this is such a quick, simple and classic recipe.
Well hello there!! I’m so, SO happy that you’re here checking out my Lemon Slice recipe… because it is seriously going to make your day! It’s quick. It’s easy. And most importantly – it’s so damn delicious. Tickety, tick, tick, tick!
If you’re new to Bake Play Smile, you might not know that one of the most popular recipes on my blog is my No-Bake Lemon & Coconut Slice (it also just happens to be my hubby’s favourite slice). If you haven’t made it yet, please do. It’s pretty darn awesome. But if you want a different kind of lemon slice (as in a baked lemon slice), this is the recipe for you!
My Lemon Slice recipe is quite literally the simplest thing ever. Basic ingredients. Basic equipment. Mix. Bake. Add frosting. That’s pretty much it. And if you’re like me and have a cute little toddler who has decided to grab onto your leg at ALL times… then this is the recipe you need! Trust me, it’s totally possible to make this slice with a little person attached to your leg!!!
I love this Lemon Slice because the base is so deliciously tangy and moist. And don’t even get me started on the frosting. It’s actually the exact same frosting I use on my classic Lemon & Coconut Slice. There’s really no reason to change it… it’s seriously delicious (and easy!!).
But rather than listen to me blabber on anymore, go and make this super easy slice. Your tummy (and that of your hubby and kids!) will love you for it. Ohhh and before you go, check out my favourite traditional slice recipes AND the best no-bake slices. Soooo much slice-y goodness!!!!
PS. Here’s a video to show how totally easy this Lemon Slice is (just in case you need any more convincing!).

Butterfly used and on Speed 6? Isn’t the max speed when butterfly is called for is speed 4?
My apologies Liz, yes that was a typo (I’ve fixed it now). It should have been Speed 4. Thanks for picking it up! xx
Oh yum, lemon slice is one of my favourite childhood treats. This looks divine!.
Mine too!
Yum! Perfect way to use up some of the crop from our hugely prolific lemon tree. Just one question: butter is so terribly expensive over here in NZ at the mo, do you have any experience of replacing butter with oil? I don’t want to damage the flavour or texture!
Hi Nikky, hmm I personally haven’t tried it with oil and don’t think it would have the same texture or flavour. You could try though!! I didn’t realise butter was expensive in NZ!!!
Thanks Lucy. It’s nearly doubled in price in the last year! 🙁
Wow I didn’t realise!!!
Same here in qld. Was paying 1.39 approx. 12 months ago and now 2.65 for 250g.
How much is the juice of one lemon? Quantity varies enormously, as it does with oranges. Then we have pulp of 3 passion fruit???? Your help would be appreciated.
Generally the juice of 1 lemon is about 3 tbs. I would adjust the amount of lemon you use in this recipe depending on your tastes. Personally I love lemon and so always add a little extra! xx
