Let’s dive into the step-by-step process of bringing these Carrot Cake Bars to life:

1. Preheat your oven to 350°F (175°C) and line a 9×9 inch baking pan with parchment paper.
2. In a medium bowl, whisk together the flour, granulated sugar, brown sugar, baking powder, baking soda, cinnamon, nutmeg, and salt.
3. In a large bowl, combine the grated carrots, applesauce, eggs, and vanilla extract. Mix until well blended.
4. Gradually add the dry ingredients to the wet ingredients, stirring gently until just combined. Avoid overmixing to keep the bars tender.
5. Fold in the walnuts and raisins if using. These add a delightful texture, much like the surprise elements my abuela loved to incorporate in her cooking.
6. Pour the batter into the prepared baking pan, spreading it evenly with a spatula.
7. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean. The aroma will remind you of cozy afternoons spent in a warm kitchen.
8. Allow the bars to cool in the pan for 10 minutes, then transfer to a wire rack to cool completely before slicing.

With these simple steps, you’ll have a batch of Carrot Cake Bars that capture the essence of home and heart.
