Preheat the oven 365F. Grease a loaf pan and line with parchment paper.
Mix soy (almond) milk and apple cider vinegar (it will be used as a vegan buttermilk substitute).
In a large bowl, use a fork to mash 3 bananas. Mix in oil, buttermilk and vanilla and set aside.
Whisk together the flour, sugar, baking powder, gingerbread spices and salt. Pour the banana mixture into the dry ingredients and stir gently.
Pour the batter into the loaf pan and bake 30 min. or until well risen and a toothpick inserted into the center comes out clean. Leave to cool completely before slicing.
Notes
Tip: for the glaze sift the confectioner's sugar (80 g) into a bowl and stir in the lemon juice (1-2tbsp) until smooth. Dizzle over the cooled cake.
