Preheat the oven to 180°C and line a baking tray with non-stick baking paper.

Toss the apple quarters in the lemon juice. Combine the lemon zest, chopped macadamia nuts and coconut in a bowl.

Combine the egg and sugar in another bowl and dip the apple quarters into the mixture.

Allow the excess egg to drip off, then roll the apple quarters in the coconut mixture.

Place on baking tray and bake for 20 – 25 minutes or until the apples are cooked and golden.
