Preheat oven to 350° F. Line a jumbo muffin pan with 10 liners and set aside.
In a large bowl whisk together the flour, sugar, baking soda, cinnamon and salt. Stir in the carrots, raisins, coconut and walnuts. Set aside.
In another large bowl, whisk together the eggs, oil, pineapple and shredded apple. Add the dry ingredients and mix with a rubber spatula until incorporated.
Fill muffin liners three-quarters full. Sprinkle each muffin with a teaspoon of sunflower seeds. Bake for 28 to 30 minutes or until centers bounce back when pressed.
