Indulge in a banoffee flapjack crumble for a comforting winter dessert. Enjoy with custard, ice cream, or cold single cream would be equally delicious, too.
Based on 6 servings, adjust as needed.
Cut the bananas into ½cm-thick slices on an angle, then arrange in a baking dish (ours was 22cm). Squeeze over the lemon juice, add a generous sprinkling of brown sugar and lightly toss together to combine.
Weigh the remaining 50g sugar and the butter, flour and oats into a bowl. Rub the butter into the dry ingredients using your fingertips, then drizzle in the syrup and add a pinch of salt. Mix everything together using a cutlery knife. Stir in the chocolate pieces, then scatter the crumble over the bananas in an even layer. Heat the oven to 200°C/180°C fan/gas 6.
Bake for 20 mins until golden and crunchy on top. Leave to cool slightly and serve warm with cream, custard or ice cream.
