Step-by-Step Instructions
- Preheat the Oven:
- Heat your oven to 350°F or 175°C and get a 9 by 13 inch baking pan ready by greasing and lining it with parchment paper This prevents sticking and ensures clean edges when you cut the bars
- Mix the Dry Ingredients:
- In a medium bowl vigorously whisk together flour baking powder baking soda salt cinnamon nutmeg and ginger if using Whisking aerates and evenly distributes all the leaveners and spices
- Combine the Wet Ingredients:
- In a large bowl whisk together vegetable oil granulated sugar brown sugar eggs and vanilla extract Aim for a smooth glossy mixture with no visible streaks or clumps This step is key for a tender crumb
- Incorporate the Carrots and Dry Ingredients:
- Gently fold the dry ingredient mixture into the wet mixture just until you see no dry streaks Be careful not to overmix or your bars can turn dense Add in the finely shredded carrots and your choice of nuts and raisins if using Fold gently to keep the batter fluffy
- Bake the Bars:
- Spread the thick carrot cake batter evenly into your prepared pan Bake for 25 to 30 minutes A toothpick inserted into the center should come out clean with maybe a crumb or two attached Let the bars cool completely in the pan This helps the flavor develop and prevents crumbly edges
- Prepare the Frosting:
- In a mixing bowl beat the cream cheese and butter together until the texture is completely smooth You want no lumps Gradually add sifted powdered sugar and vanilla extract Keep beating until the frosting is light fluffy and easy to spread
- Frost the Bars:
- Once the carrot cake bars are totally cool dollop the frosting all over the surface Use a spatula or knife to create decorative swirls or a perfectly smooth finish
- Serve:
- Cut the frosted slab into even squares and transfer to a serving platter Enjoy immediately or stash leftovers in the fridge in an airtight container

Storage Tips
Store the frosted bars in a tightly sealed container in the refrigerator for up to five days Layers of wax paper between the bars help keep the frosting pristine If preparing ahead freeze the unfrosted bars and frost right before serving for best texture
Ingredient Substitutions
Swap half of the oil with unsweetened applesauce for a lighter version No nuts Use pumpkin seeds or leave them out entirely For dairy free try a plant based cream cheese and margarine in the frosting If you are out of brown sugar simply use all white sugar though the bars will be a bit less rich
