Preheat the oven to 425℉.
In a bowl, mix the eggs, oil, sour cream, honey and the vanilla together. Separately, add the flour, baking powder, salt and spices to a bowl. Combine the dry and wet ingredients.
Next, fold in the carrots, zucchini and walnuts. Fill the muffin cup with the batter and leave a little room for them to rise at the top. Place the pan in the oven and bake for 15 minutes or until muffins are done.
Remove them from the oven and allow the muffins to cool before serving, enjoy.
