This apple crumble slice brings crumble and cake together to make one mouthwatering dessert or afternoon treat.

Traditional cinnamon and apple flavours are combined with soft sponge and topped with a crumble in this delicious twist on an apple crumble recipe. In all other ways apart from shape, it's much like a traditional apple crumble. It has a buttery, sugary, crunchy topping with soft apples at the bottom. We've used cinnamon to give it that warming kick, too. However, these are sliced up into pieces.

  3. Add the milk and vanilla and mix, then add the flour and mix until just combined and pour into the tin.
