I absolutely love this recipe for Lemon Crumble Slice. It’s by far one of my favourites (and that’s really saying something, given my addiction to all things involving sugar). I love this slice because not only does it have the yummiest oaty layers, but it seriously has the most amazingly creamy and delicious lemon filling. Creamy + lemony + oaty = all kinds of awesome.
The Thermomix really does make this lovely little recipe so simple. There’s really not much to it. Once you’ve made the oat layers, you whip up a simple lemon filling. No mess, no hassle. Gosh it’s recipes like this that really make me love my Thermomix. A LOT!!
So what are you waiting for? If you’re a fan of lemon flavoured desserts and slices, then you really, really must make this. You’ll love it – I pinky promise!!!

I’m keen to try this. Has anyone tried with out the lemon extract?
ok so I’m confused, at number 11 you say to spread half of the crumb mixture into the tray, are we then supposed to side aside the other half? or do we leave it in there & zest the lemon on top of it? The instructions aren’t clear.

Yes you set the second half of the crumble mixture aside (as that is what you crumble over the top). The lemon zest forms part of the middle (the creamy portion).
I have made this 4 times. so good. i don’t have lemon extract so skip it. still tastes great
That’s excellent!
Can the oats for substituted for something else to make this Gluten Free?

Hi Tammy, I’m not sure as this is the only way I’ve made it. You could try experimenting though!!
This recipe is delicious. Thank you.
Can you please tell me if this slice is suitable to freeze?

I personally dont like to freeze this slice as I have found that the filling can go a bit runny when defrosted. That being said, I know other people who are happy freezing it!! xx
