Prepare the flax eggs by mixing 2 tbsp ground flaxseed with 5 tbsp of water in a small bowl. Leave for 10-15 minutes to set.
In a large bowl, mix together the flour, ground almonds, salt and baking powder. Pour in the lemon juice, maple syrup and coconut oil, then fold in the set flax eggs and lemon zest.
Mix the batter, then pour into a loaf tin lined with baking paper (I used a 22×12 cm loaf tin).
Bake for 45-50 minutes until the top is golden brown and a skewer inserted into the centre comes out clean. Leave to cool completely before icing.
Mix the icing sugar and lemon juice in a small bowl, then pour over the top of the load and spread evenly with a spatula to cover the top.
