Preheat the oven to 350F
Grease a loaf pan with softened butter and flour - shake off the excess flour.
Zest the rind of the mandarin, divide in half and set it aside.
In a large mixing bowl, whisk together the flour, sugar, baking powder, and salt. Set aside.
In a second mixing bowl, whisk together the coconut milk, eggs, and vanilla extract.
Carefully fold the wet ingredients into the dry ingredients.
Gently fold the softened butter into the mix as well.
Pour the batter into the loaf pan and bake for approximately 50 minutes.
Leave to cool on a wire rack while you make the glaze.
Combine the confectioner's sugar and mandarin juice in a cup to make the glaze.
Once cool, turn the loaf onto a wire rack and put it on top of a board.
Slowly pour the glaze over the loaf. Top with remaining mandarin zest.
