Preheat the oven to 350°F (175°C). Line an 8×8 inch baking pan with parchment paper, leaving an overhang on the sides for easy removal.
In a large mixing bowl, combine the rolled oats, shredded carrots, chopped walnuts, shredded coconut, ground flaxseed, ground cinnamon, ground nutmeg, ground ginger, and salt. Stir well to evenly distribute the ingredients.
In a small microwave-safe bowl, gently warm the honey, almond butter, and applesauce for about 20-30 seconds until they are easier to mix. Stir in the vanilla extract.
Pour the wet mixture over the dry ingredients and mix thoroughly until all the dry ingredients are well coated and the mixture is sticky.
Fold in the raisins evenly throughout the mixture.
Transfer the mixture to the prepared baking pan. Using a spatula or your hands, press the mixture firmly and evenly into the pan to create a compact layer.
Bake in the preheated oven for 22 to 25 minutes, or until the edges are golden brown and the center is set.
Remove from the oven and allow the granola bars to cool completely in the pan on a wire rack. Once cooled, use the parchment paper overhang to lift the bars out of the pan.
Cut into 12 equal-sized bars and store in an airtight container.
