Pre-heat oven to 180°C (375°F) grease your loaf tin and line it with a sheet of baking paper
In a large bowl scoop in your apple sauce and puree with a handheld mixer or in a blender.
Add the plant milk, lemon zest, oil, vanilla and sugar to the apple puree and stir well.
If you're are using a standing blender you can add these ingredients to the blender and blend again until smooth.
In a separate bowl, sift together flour, baking soda, cinnamon, and salt.
Add the flour mixture to the apple mixture and stir until just combined.
Pour the mixture into your lined loaf tin and smooth out the top. If you are not adding icing later sprinkle on your flaked almonds now (before baking). If you are adding icing leave them for later.
Bake for 50-55 minutes at 180°C / 356°F minutes until a wooden/metal skewer inserted in the middle comes out clean.
Remove from oven and cool in loaf tin for at least 10 minutes.
Then transfer to a cooling rack to cool completely before adding icing.
