In large mixing bowl, add flour, sugar, coconut, cinnamon, baking soda, salt and baking powder. Whisk together.
In another medium size bowl, whisk eggs, oil, and vanilla. Add grated carrots, zucchini and apples.
Mix together, until all fruit and vegetables are mixed well. Do not use a mixer, mix by hand!
Pour liquid ingredients into dry ingredients all at once.
Fold until all incorporated, adding raisins and nuts if using. The batter will be very thick.
Scoop the batter into greased muffin pan using a large cookie scoop. Or use a large spoon or measuring cup. Fill the muffin tins almost to the top to ensure full, rounded muffin tops.
Bake the muffins for about 16-18 minutes or until golden and the top springs back when touched lightly. You may also insert a toothpick in center of muffin, if it comes out clean, muffin is done.
Leave the muffin in the tin or on a cooling rack for about ten minutes to cool.
