Preheat oven to 200ºC. Lightly grease a doughnut baking tray with spray oil. In a bowl, add the coconut oil, sweetener and eggs and whisk to combine. Add yoghurt, milk and vanilla and continue to whisk.
In a separate bowl, combine the flour, salt and shredded coconut. Fold dry ingredients into wet. Add frozen raspberries into batter and stir until just combined.
Scoop batter into each doughnut mould and bake for 15-20 minutes, or until doughnuts are lightly golden on top. Place on a rack and allow to cool completely before glazing.
For the glaze, place icing sugar into a bowl and whisk in lemon juice slowly, adding more or less depending on the consistency of the glaze you’d like. Dip doughnuts into the glaze and on to a wire rack with a tray underneath to catch the excess glaze. Double dip for a thicker icing on top. Sprinkle with roasted coconut chips while the glaze is still wet. Serve with a cup of tea!
