Blackberry Oaty Traybake – Ideal for Late Summer

This blackberry traybake is a delicious way to enjoy the fruit from those heaving bramble bushes, whether you’ve picked them from a nearby field or lane, or a pick-your-own farm or even just from the nearest park.

Late summer with its bountiful harvest of rich blackberries, plums, and all kinds of soft fruits – in a way this time of year makes me sad, sad that summer is nearly over, with that bittersweet yearning you get for missing out on something, the sense that summer is coming to a close.

But also there is the excitement of the new (school) year to come as well.

Oozing with blackberry juice, this blackberry traybake or sheet cake is perfect sliced into squares and packed up for a picnic or added to a lunchbox.

Using oats in a cake makes it feel much healthier than your usual cake, in fact it would also work well for breakfast. Cake for breakfast = winning!

Not quite the same as a flapjack which is denser and more chewy, this is a light oaty cake with a layer of mashed blackberries through it. As you slice through the deep red of the blackberry layer inside is revealed, it makes the cake juicy and soft.

I tried this combination of ingredients after picking up some lovely blackberries at the supermarket. An open packet of oats was calling out to be finished off in my cupboard, and knowing that oats can be made into flour using a food processor, I thought I would see how it would turn out. Not having a food processor to hand, I used them whole in my blackberry oaty traybake.

How happy my children were to see I had been baking! They love picking blackberries if we spot brambles down at the park as well as at our local pick-your-own farm.

Those juice-stained faces and hands are always a dead giveaway that they’ve been trying a few samples!

That deep red juice just oozes out. It’s a lovely bake to make as you want it to look rustic, so you don’t need to spend too much time on spreading the mashed blackberry layer too carefully.

I just dolloped it in, spread it round and then topped with the rest of the oat mixture.

Blackberries are also a big favourite here in that autumn and winter staple, the fruit crumble. I’ve found that the flavour of blackberries is enhanced by the addition of rose water, as shown in my blackberry and rose crumble.

My oaty traybake is almost a tidier way of eating a crumble, in bar form. The good thing about the traybake though is that the fruit is unsweetened and really shines on its own.

If the tart flavour of blackberries is a favourite with you, you must try this recipe.
