Soft Carrot Cake Bars with Cream Cheese Glaze

"The bars are super soft, moist, dense, and not at all cakey. They aren't like traditional carrot 'cake' and are like carrot cake blondies because of how buttery and rich they are. The bars are robustly flavored with cinnamon, ginger, allspice, nutmeg, and cloves before folding in as many carrots as the batter can hold. There's enough spices so you know they're there, without being overwhelming. I grate my own carrots because storebought bagged shredded carrots are usually coarse and thick, and don't bake up very nicely. I kept out all raisins, dried fruit, nuts, chocolate, etc. but 1/2 cup to 1 cup total of your favorite add-ins can be incorporated. The bars are so soft and moist from the juicy carrots and the brown sugar, and they don't need gobs of frosting. They're comforting, homey, packed with flavor, and the carrots add so much chewy texture...."
