Firstly, line up the muffin trays or cup cake trays with suitable liners of your choice.
Switch on the oven and preheat at 180°C or 350º F.
In a food processor or blender, make a puree of chopped apple pieces, milk, oil, essence, sugar, food colour and vinegar.
Transfer this puree into a large bowl.
Into the same bowl sieve in the whole wheat flour, all purpose flour, baking soda, baking powder and salt.
Using a spatula gently cut and fold everything , till the wet and dry ingredients combine perfectly.
Using an ice-cream scoop, pour in this batter into the cup cake moulds up to ¾ level of each hole.
Put the trays into the pre-heated oven
Bake them for 15-20 mins or until a toothpick inserted comes out clean
Take the trays out and put them on the cooling rack.
Once they are cooled completely, only then remove the cupcakes from the trays.
