Blackberry Cake Bars

Blackberry cake bar

In my memory, blackberry picking always took place in the cold on the windswept downs of the Isle of Wight. So every year I am surprised when blackberries appear in abundance in August. Luckily we have some at the end of the road so if I ever feel the need for a blackberry fix, I only have to go round the corner.

This recipe uses both blackberry jam and fresh blackberries. If you don’t have any blackberry jam it won’t take you too long to make some and if you need any tips for jam making, check out this post.

I found the inspiration for this recipe in my new favourite cookbook, the Yeo Valley Great British Farmhouse Cookbook. Contrary to my expectations, not every recipe contains yogurt. Or even dairy produce.

I adapted this recipe from the original to suit my ingredients and tin size and made a slightly smaller, but deeper, cake bar.

This is so good warm and would make a brilliant dessert with custard or your favourite alternative accompaniment, either as a bar, or baked in a deep round cake tin with a removable base, or even a pie dish with a removable base. You would just need to adjust the cooking time accordingly.

It is also delicious cold and makes a great picnic bar.



For the Base

150g soft butter or margarine

50g icing sugar

150g plain flour

35g cornflour

200g blackberry jam

For the Topping:

125g butter or margarine

125g soft brown sugar

Grated zest of one lemon

175g SR flour

25g ground almonds

200g blackberries

25g flaked almonds


Line a tin with baking parchment and set the oven to 180ºC. I used a 20x25cm roasting tin.

Cream the butter and icing sugar together until pale and fluffy.

Mix in the flour and cornflour to form a soft dough.

Tip into the tin and carefully and evenly smooth over the base.

Spread the base evenly

Bake for around 15 minutes.

Remove from the oven and allow to cool while you make the topping.

For the topping, cream the butter and sugar together.

Beat in the lemon zest and eggs one by one.

Fold in the flour and ground almonds.

Spread the jam over the biscuit base and dollop small spoonfuls of the cake mixture over the jam.

Carefully and evenly smooth over the base.

Scatter the blackberries over the mixture and gently press them into it.

Scatter over the flaked almonds.

Ready to bake

Bake for around 45-55 minutes, until golden brown and a skewer inserted into the middle comes out clean.

Allow to cool for a while in the tin before removing and leaving on a wire rack to cool fully.

Slice into bars and enjoy!

  1. We have a load of blackberries near us and I’m looking for some ideas other than just making jam. These look delicious and really good for lunch boxes.

  2. Oh, this looks so delicious…perfect with a cup of tea…even though sugar is not my friend…i officially have cake envy.

  3. Blackberries around the corner? Lucky you! And such a tasty way to get a blackberry fix.

  4. Yum! This looks divine! I love the addition of that gorgeous shortbread and jam base. It’s been so long since I’ve had a fresh blackberry (sigh!) as they’re not grown here in Australia, as far as I know. I might have to try this with frozen blackberries. Definitely not as nice but it’ll have to do. Thanks for the gorgeous recipe (oh, and I would have assumed the Yeo Valley cookbook was all yoghurt recipes too! Haha) xx

  5. Yum! These look so good! I have some blackberries I should try this!

  6. Oh this is lovely! I think the Isle of Wight is a beautiful place but the wind! It must be something in the winter.

    • Especially at the top of the Downs! And I remember physically battling with the wind on a regular basis round one particular corner when it was windy, just down from where we lived. I haven’t thought about that in a while but your comment has reminded me!
