The simplest way of describing a buckle is a cake, laden with fruit (I have chosen blackberries because they are still in season here) and topped with an oaty crumble. However, some recipes don’t have a topping and some recipes pile  half the fruit on top of the cake batter so I’m not sure there is a definitive way of cooking buckles. Either way it is delicious-served warm with custard for pudding, or cold with coffee midmorning or tea at four o’clock.

Ingredients

  • For the topping
  • 90g porridge oats
  • 40g plain flour
  • 60g cold unsalted butter, cubed
  • 60g demerara sugar
  • For the buckle
  • 240g plain flour
  • 2 teaspoons baking powder
  • Pinch salt
  • 150g unsalted butter, softened at room temperature
  • 130g golden caster sugar
  • 2 medium eggs, beaten
  • 1 teaspoon vanilla paste (or extract)
  • 90ml buttermilk
  • 400g blackberries

Method

  1. For the topping, put the porridge oats and flour in a mixing bowl and rub in the butter until no visibly large lumps remain. Stir in the sugar and set aside.
  2. Heat the oven to 180˚c, fan oven 170˚c, mark 4. Grease and line a 9 x 9 inch (22.5 cm) square cake tin with non-stick baking parchment. Mix the flour with the baking powder and salt and set aside. Cream the butter and sugar together in a mixer or with an electric beater. Slowly beat in the eggs followed by the vanilla paste. Stir in the buttermilk-don’t worry if it looks curdled. Fold in the flour mixture until you have a smooth batter. Fold in the fruit.
  3. Spoon the batter into the prepared tin and spread to the edges, leveling out the surface. Sprinkle over the crumble topping. Bake in the oven for about 40-45 minutes until the cake feels firm in the centre and a skewer inserted comes out clean. Leave the cake to cool in the tin for 20 minutes then carefully lift it out and place on a wire rack. Cut into squares and serve warm with custard or cold with a cup of coffee or tea.
