Pre-heat oven at 350°F (175°C)
In a mixing bowl, add the zucchini, carrots, banana, eggs, vanilla extract, oil, and brown sugar. Mix well.
In another bowl, add the flours, baking soda, spices, and salt. Mix until well combined.
Add the dry ingredients to the wet ingredients and mix just until combined.
Stir in the dates (make sure they are separated and not in clumps), chocolate chips, and chopped nuts if using.
Divide the batter into a 12-muffin silicon tray and sprinkle with rolled oats (and a chocolate chip!)
Bake for 20-23min, checking at the 20min mark to see if those additional 3min are needed! Make sure the toothpick comes out clean (or only covered in chocolate). Muffins should be perfectly golden.
Let cool in the muffin tray for 10min then transfer to a wire rack.
Enjoy warm with a cup of coffee and drop some off to your friend's place for their family to enjoy too!
