  • 180 g blackberries
  • 4 tablespoons crunchy peanut butter
  • 1 ripe banana mashed
  • 1.5 cups rolled oats
  • 1.5 tablespoons cacao or cocoa
  • 2/3 cup almond flakes a little less than a cup
  • 50 g butter plus a knob for greasing the tin
  • 5 tablespoons honey/maple or agave syrup


  • Preheat the oven to 325 F/ 170 C/ gas mark 3. Lightly grease a square 20cm tin (or equivalent), line with baking paper and set aside.
  • In a saucepan combine the blackberries, butter, banana, honey and cocoa, and cook over a low heat for about 7-8 minutes, squashing the blackberries with the back of a spoon or fork, stirring often. Remove from the heat and stir in the peanut butter. 
  • In a large bowl combine the fruit mixture with the oats and almond flakes, stir thoroughly, then pack the mixture tightly into the baking tin. Smooth out the top with the back of a spoon or spatula and bake for 25 minutes.
  • Remove from the oven and let cool before cutting into bars (or other shapes).
