- Preheat oven to 350°F.
- In a mixing bowl, stir together the carrots, orange juice, vanilla, olive oil, honey, and pineapple until well blended.
- In another bowl, stir together the flours, baking soda, and spices. Mix in the walnuts.
- Blend the dry ingredients into the carrot mixture, stirring until just mixed.
- Pour the batter into a 12-cup muffin pan lined with paper liners. Fill muffin cups 2/3 full. Bake for 30-35 minutes.
Note: You can also pour the batter into a nonstick 8-inch-square baking pan and bake for 45-60 minutes until a knife inserted in the center comes out clean. Remove from oven, let cool slightly, cut into 12 pieces, and serve.
