Preheat the oven to 356 degrees Fahrenheit.
Line the bottom of 2 8-inch tins with parchment paper. Spray it with non-stick cooking spray.
In a large bowl, whisk the flour, baking soda, nutmeg, cinnamon, raisins, and salt together. Place it aside for the moment.
In another large bowl, whisk the eggs, natural maple syrup, almond milk, and vanilla extract until the mix is smooth.
Now gently add in the carrots.
Combine the mixture from the first bowl into the second and combine them well until you get a smooth texture.
Pour the mixture evenly into the two trays.
Bake them for 25-30 minutes. Then let it cool in the tin.
Meanwhile, mix the icing ingredients and refrigerate.
When the cakes are cool enough, remove them from the tins. Cover one cake with icing. Place the other cake on top then top it with icing. Finally, decorate with the remaining pecans.
