A delicious lunchbox treat or an afternoon tea showstopper 

August only means one thing in my household and thats plums. We have our beautiful plum tree in the back yard that year after year provides the most beautiful fruit. Much like our raspberries after we’ve been eating plums for weeks, have enough jam to last the year and incorporated them into every dish we can think of I have to start to get creative.


These bars have a beautiful shortbread base topped with a delicious crumble and sandwiched between is a gloriously sticky plum jam. Absolutely perfect for a cheeky lunchbox treat or let them take pride of place at your next afternoon tea.

Super simple to make this three step process is simple enough for even the novice baker.


Ingredients – for the crumble 

  1. 100g demerara sugar
  2. 100g plain flour
  3. 50g ground almonds
  4. 60g butter – cold
  5. pinch of salt

Ingredients – for the base

  1. 420g plain flour
  2. 180g butter
  3. 100g sugar
  4. 100g icing sugar
  5. 1tsp vanilla essence
  6. pinch of salt

Ingredients – for the filling

  1. 1kg pitted plums, sliced
  2. 470g sugar
  3. 250ml water
  4. 1tsp vanilla essence


Method – for the filling

  1. Preheat your oven to 190C/375F
  2. Line and grease an 8×8 baking tin
  3. Add plums, water, sugar and vanilla to a large pan, cook over a medium heat until the plums start to break down. Once the plums are soft take the pan from the heat and leave to cool. (feel free to start on the base and crumble mix whilst the filling is cooking/cooling)
  4. Once cool transfer to a blender and blend until smooth
  5. Pop the mixture back in the pan and cook again over a medium heat for around 15-20 minutes stirring occasionally so that nothing sticks. Once you can scrape your spoon through the mixture and see a trail you are there. Leave to one side off the heat whilst you finish the base and crumble.

Method – for the base 

  1. Using a stand alone or electric mixer, cream together your butter, vanilla, sugar and icing sugar.
  2. Slowly add in the flour and salt until combined
  3. Press the mixture into the baking tin until it is flat and even
  4. Bake for 15 min

Method – for the crumble 

  1. Mix all of the dry ingredients in a bowl
  2. Cut the butter into cubes then add this to the dry ingredients
  3. To make the crumble rub the butter and flour mixture between your fingers. Keep going until you have a crumbly texture.
  4. To assemble the bars take the base in the tin, cover with a layer of the filling, and top with another layer of the crumble.
  5. Pop the bars into the oven for 20-30 minutes until everything is beautifully golden brown.
  6. When baked leave in the tray and pop in the fridge to cool. It will be much easier to slice when chilled.


And there you have it. Gorgeous plum crumble bars, perfect for any occasion.
