Original post (with pictures) here.

2 tsp chia seeds in 1/2 cup water
1 small butternut pumpkin, or 1 cup cooked and mashed pumpkin
2 cooking apples
1 cup self-raising flour
1/4 cup brown sugar
1 tsp baking powder
1 tsp mixed spice
1/4 tsp cardamom
1/2 cup apple sauce (mine was sweetened)

1. Preheat your oven to 180'C and prepare a loaf tin. Combine the chia seeds with water and set aside.
2. If cooking pumpkin from scratch, peel and chop your pumpkin and then steam pumpkin pieces for 15-20 minutes or until soft.
3. Roughly chop one of the apples and steam or boil for roughly 10 minutes (I added my pieces to the pumpkin steamer half-way through).
4. Finely slice the remaining apple and set aside.
5. When the pumpkin and apple have cooked, mash together roughly.
6. In a large bowl, combine the flour, brown sugar, baking powder and spices. Mix to combine. Add the apple sauce and chia-water mix. Add the mashed pumpkin-apple mix and mix well.
7. Transfer the batter to your loaf tin and then arrange the remaining apple slices on top.
8. Bake for 40 minutes, or until an inserted skewer comes out clean.
