Pre-heat the oven to 350 degrees F and grease a small casserole dish. Mine is a unique size of 6×8 but anything close to that will work including a 9×5 bread loaf pan or an 8×8 inch brownie pan (although you might want to slightly alter the baking time depending on your size).
Add all ingredients to a blender MINUS the carrot and nuts. Blend until creamy and little to no chunks of the oats remain. Fold in carrots and walnuts.
Pour batter into the greased baking dish and top with additional shredded carrot and chopped nuts as desired. Bake for 25-30 minutes (mine was perfect at 25 minutes).
Unlike my original version, this one ends up closer to the consistency of oatmeal (less cakey) but it's still SO GOOD! ENJOY!
