Cranberry and apple crumble bars have a fruity filling sandwiched between two layers of oat crumble. These fruit crumble slices can be served hot or cold, as a dessert with cream, custard or ice cream, or can be enjoyed with a cup of tea or coffee.
Sift the flour into a large bowl and add the baking powder and butter. Rub in the butter until the mixture resembles breadcrumbs. This stage can be done in a food processor if you prefer.
Stir in the oats and sugar and mix. Place in the fridge until you are ready to assemble the cranberry and apple crumble bars.
To prepare the fruit filling
Peel and core the apples, chop into small pieces and place in a medium sized saucepan.
Add the orange zest, cranberries, sugar and sufficient water to almost cover the fruit.
Simmer gently until the apples have softened, stirring from time to time. Add a little more water if necessary.
To assemble the fruit crumble bars
Spread half the crumble mixture over the base of the lined tin. Press into place and compact with the back of a spoon.
Spread the cranberry and apple filling evenly over the crumble base making sure there is an even distribution of apples and cranberries.
Spoon the remaining half of the crumble mixture evenly over the top of the fruit filling, making sure that the fruit is all covered and none is protruding through the crumble.
To bake
Bake in the centre of the oven at 190oC, 375oF, gas mark 5 until slightly golden on top (around 25 to 30 minutes).
Place on a wire rack and leave to cool in the tin.
