Preheat oven to 350°F (175°C). Line a muffin tin with paper liners.
In a large bowl, mix flour, sugar, brown sugar, baking powder, baking soda, salt, cinnamon, and nutmeg.
In another bowl, whisk eggs, oil, and vanilla extract.
Add wet ingredients to dry ingredients and mix until just combined.
Fold in grated carrots, walnuts, and raisins.
Divide batter evenly among muffin cups.
Bake for 20-25 minutes or until a toothpick inserted into the center comes out clean.
Let muffins cool in the tin for 5 minutes, then transfer to a wire rack to cool completely.
For coconut whip, refrigerate coconut milk overnight. Scoop out the solid part into a bowl.
Add powdered sugar and vanilla extract to the coconut cream and whip until fluffy.
Serve muffins with a dollop of coconut whip on top.
