For the blackberry caramel

  • Put the blackberries in a non-stick, non-reactive pan and heat over a medium to high heat with two tablespoons of water and a pinch of salt
  • Cook for a few minutes, until the blackberries change colour and start to release their liquid and become squishy. Remove to a bowl and squash with the back of a fork.
  • Wipe out the pan and melt the sugar slowly. Add the butter and crème fraiche and cook for 3-5 minutes, until you have a smooth caramel sauce.
  • Add in the blackberries and their juice and cook, stirring into the caramel. You should have a lovely, slightly purple fruity caramel.
  • Season with salt to balance and bring out the flavours

For the blondies

  • Preheat the oven to 180 degrees and line a high sided, 18cm x 25cm (7in x 10in) high sided metal baking tin with greaseproof baking paper.
  • In a medium bowl, stir melted butter and brown sugar until smooth.
  • Next add the egg, vanilla, salt and stir vigorously until smooth.
  • Add the flour and half the almonds and stir until no streaks remain.
  • Spread half the batter across the baking tin, top with the blackberry caramel, spreading it out as evenly as you can.
  • Top with the rest of the batter and spread out over the caramel, using a toothpick to marble. Press in the remaining blackberries and scatter over the flaked almonds.
  • Bake for 20 to 25 minutes until a toothpick inserted into the middle comes out relatively clean.
  • Transfer quickly and efficiently onto a wire rack to cool, then cut into squares and serve garnished with blackberries.
