  1. Heat oven to 180C/fan 160C/gas 4. Butter and line a 20 x 30cm baking tin with baking paper. Put the butter, sugar and ground almonds into a food processor, then pulse until the mixture resembles very rough breadcrumbs. Spoon out half the mix into a bowl and set aside.

  2. Add 140g flour into the mix in the processor and whizz until it just forms a dough. Tip into the tin and press down with the back of a spoon. Bake for 15-20 mins until golden. Leave to cool for 10 mins.

  3. To make the filling, put the remaining butter and the sugar and almond mix back into the processor, saving a few tbsp for the topping. Add the eggs, the 25g flour, cinnamon and baking powder and whizz to a soft batter. Spread over the base.

  4. Top with the plum pieces and a little extra caster sugar and cinnamon. Bake for 20 mins, then sprinkle with the remaining crumble mix and flaked almonds. Cook for another 20 mins or until golden. Leave to cool in the tin before slicing.

Sorry - was so enthusiastic about my review that I forgot to rate it. Would give it 6 stars if I could.

This recipe is AMAZING! It's so amazing that I even though I managed to burnt the bottom of it was still one of the most amazing desserts I've ever had :) Looking forward to making it again when my parents come to visit. (Clearly, I will be attempting not to burn the base next time).

Oh yeah, the plums I had were a little underripe so I stewed them very lightly with some agave syrup. I think that was the only thing I did differently...

This went down a treat on cake day at work !

Although I thought it was a bit time consuming (do the base, in the oven, do the filling, in the oven, do the topping in the oven!) I have to admit the comments recevied at work today makes it so worthwhile! I did find that the mixture wasn't quite breadcrumb texture at the end of step 1, despite using v cold butter. But nonetheless, no-one complained ;-)

Great cake large amount of ground almonds lovely, used soft marg instead of butter as I always do.

I must try this recipe, it sounds quick and easy, that's for me. Will write a comment when I've made this delicious sounding tray cake.

Please help - tried to make this twice now and tastes amazing, BUT the base has burnt both times, despite following time/temperature in recipe. Could it be due to using a thickish tin to bake in, the baking paper or just needs less time in the oven? Any thoughts much appreciated, thanks!

Does anyone know how long this would keep for? Would like to make some for a hamper, so would need to keep for a few days. Please let me know! Thanks.

I only had 200g ground almonds but the base was perfect - firm but not too soft or crunchy. I cut the plums into smaller pieces and added half a tsp of vanilla essence. I also added a little demerara sugar to the crumble mixture to make it crunchy. My work colleagues were super impressed!

Lovely cake. I always enjoy making this one in late summer/early autumn.

tasted lovely if a bit soggy, found it difficult to save some of the mix for the topping and by the time the cake had cooked the flaked almonds just sit on the top but a good tasting recipe

Easy to make and very tasty. Bit concerned about how much mixture to keep back but worked out fine. Will be making again. Not crumbly at all as others suggested - maybe I did it wrong but tastes good anyway!

This was really easy to make, and the plums just melted into the sponge. Beautiful!

Brilliant way to use a plum glut. Rather too crumbly when taken on a picnic, but delicious

Made this with raspberries when the family came to stay, and everyone loved it. For the topping, I just broke off blobs of the mixture and scattered them over the top, thinking perhaps the raspberries would burn or dry up as some were left uncovered, but it cooked perfectly. A great dessert - perhaps a touch sweet - and what was left over kept well, uncovered, in the fridge. I can highly recommend this one.

Amazing recipe, absolutely delicious & I think it's one of those where you can deviate a bit and it'll still be gorgeous. I doubled the recipe to fill a large bakingtray. Having read other comments I didn't double the butter (did about x1.7 instead) and it didn't matter, the pastry was light & crispy and the filling was moist. My base never resembled breadcrumbs either.
For the topping, because I had dough instead of breadcrumbs, I added more flour, 100g of chopped almonds and some granulated brown sugar, so it was a bit more crumbly to spread on top and easier to cut without losing it. It was so so delicious, the ones I took to kindergarten went in a blink and my husband and both children ( 4 and 2) loved it too. Don't normally write reviews, but this cake is straight into family favourites.

I made this for my sisters 60th Birthday party. It got rave reviews! My brother described it as a 'trensendent' dessert (= very very yum). Not a scrap of it left over. Strongly recommend it and will be making it again.

I made this yesterday with my daughter and niece, we made it by hand rather than in a food processor and the girls had a great time making it. The recipe works perfectly and if a 2 and 5 year old can make it then anyone can! I swapped half the ground almonds for oats cause I'd ran out and it still worked well. The girls and the rest of the family were very happy with their results!

I couldn't get hold of plums, so used apples instead! Turned out beautifully and went down very well. Next time i will make extra crumble for the topping. Yum!
