Fruity and scrumptious raspberry crumble bars with an oaty crumble base, raspberry filling, and much more scrumptious crumble on prime!

Say whats up to a number of the most scrumptious bits of heaven you’ll ever eat… these raspberry crumble bars. They’re HEAVENLY and simply so extremely moreish and delicious. 


So yeah, one other traybake so as to add to my by no means ending roster of bakes that I’m at all times in love with. Actually, if in case you have adopted me for some time you’ll know {that a} traybake associated bake is considered one of my favorite issues ever and that’ll by no means change. 

Traybake can are available many a type, reminiscent of brownies, blondies, cookie bars, flapjacks and so forth. These raspberry crumble bars are a brand new one so as to add to the listing of goodness.

All of my traybake recipes, if I may help it, are made into a 9″ sq. tin. That is for ease, and in order that I cut back the quantity of ins and outs it is advisable to purchase! I at all times use this traybake tin


So everyone knows what a crumble is correct? Its some of the iconic traditional issues you’ll be able to ever eat. I’ve diverse crumble associated bakes on my weblog reminiscent of my apple crumble traybake, and even my apple crumble cupcakes.. however this one? Oh that is on one other league. 

It isn’t fairly ‘crumble’ to the concept of a traditional dessert – however its a crumble like oaty scrumptious combination of substances that create the most effective base and topping for these bars. 

  • Oats – for this bake, I needed an oaty flavour to come back via to go with the raspberries and likewise create a extra textured crumble. 
  • Flour – an apparent one, however plain flour is a should!
  • Sugar – I made a decision to make use of mild brown comfortable sugar, however this could work nicely with different sugars reminiscent of caster sugar, and even darkish brown comfortable sugar. 
  • Elevating brokers – this one could sound somewhat odd, however belief me – you need the tiny raise from the baking powder!
  • Butter – I exploit unsalted butter as at all times, however a salted butter would work nicely additionally. I might keep away from any baking spreads of margarines as they’re too comfortable for the crumble combination. 


The principle half proper? The raspberries! A scrumptious candy and sharp combination of heaven. I made a decision to not simply add in some raspberries and hope for the most effective, and I didn’t simply wish to do a layer of jam as some recipes do… I needed to stage it up and make a combination! 

  • Raspberries – So for ease, I might advocate recent berries. You want to have the ability to mash them up and frozen would make this too arduous. You’ll be able to attempt thawing frozen berries, however you would wish to eliminate any extra liquid earlier than utilizing them. 
  • Jam – A raspberry jam – a traditional! Seedless, with seed, easy, lumpy… no matter! 
  • Lemon – The lemon is required to chop via the sharpness of the raspberry but additionally deliver out the flavour splendidly. 
  • Cornflour – A thickening agent on this case. Please use it, it’s a lot better than simply utilizing plain flour. 

It might sound foolish within the methodology, however truthfully the easiest way I discovered to make this filling was so as to add the substances to a bowl and mash them barely with a potato masher. It meant I nonetheless had texture, however every little thing had blended in nicely sufficient. 


As you’ll be able to see from the pictures there are layers to those raspberry crumble bars. It’s pretty merely although – a majority of the crumble combine goes into the lined 9×9″ sq. tin and also you press it down firmly. I discovered 500g of the crumble combine was excellent for this layer after some experimenting with ratios. 

Then, you prime the bottom with the mashed raspberry combine and unfold evenly, after which sprinkle over the remainder of the crumble combine. This a part of the crumble combine doesn’t want urgent down as it will flip right into a raspberry mush. 


For a bake like this, and principally any bake ever until acknowledged in any other case, you want a preheated oven. I’ve a fan oven so I bake at 180ºc on the fan setting, however if in case you have a daily oven it will be 200ºc. That is additionally so far as I’m conscious fuel mark 6, or 400ºf if that helps – though I’ve by no means baked in a fuel oven. 

The temperature is barely increased in comparison with different traybake recipes I’ve completed, however you need the additional heat to actually begin toasting and baking the crumble combine and it actually helps. 

The combination might be barely comfortable, so make certain the crumble combination is popping splendidly golden and exquisite earlier than taking out of the oven. 

Ideas and Methods 

So relating to making a bake like this, it’s surprisingly straightforward, however there are methods to assist make certain it really works splendidly. When making the crumble combine I merely use a big bowl, add the substances, and rub them along with my fingertips. This implies you’ll be able to nonetheless have the great texture of the oats within the crumble with out unintentionally destroying them in a meals processor or mixer.

For the raspberry combine, I genuinely simply use one other bowl and a potato masher – however a big spoon or fork works nicely, it simply takes a bit longer. You don’t wish to over combine this both as you need texture to the combination. 

As talked about above, I exploit this traybake tin as its the proper measurement.
