Pre-heat the oven to 180 C / 350 F
Grease a 9" cake pan with some butter
In a bowl, mix together the almond flour, coconut, and brown sugar
Add lime zest to this mixture and stir well to combine. Lime adds a beautiful flavour to the cake so please don't skimp on it
Add melted and cooled butter to the above
Mix gently to combine
Add vanilla and salt and mix again
Add the eggs and beat again until you get a smooth mixture. You can also beat the eggs separately in a small bowl and add to the batter at this stage which is probably what I'd do if I made this almond cake again
Transfer to the greased cake tray.
Smoothen the top and gently tap the cake pan on the kitchen counter to let out any air bubbles.
Add almond flakes on top evenly.
Bake in pre-heated oven for 40 minutes or until a skewer inserted into the centre of the cake comes out with moist crumbs
Cool completely, cut, and serve
