These carrot cake bars are my go to treat when I want something comforting and crowd pleasing without a lot of fuss. Moist and warmly spiced with sweet shredded carrots and a thick swirl of cream cheese frosting they take all the best parts of classic carrot cake and turn them into an easy shareable dessert for everyday or special gatherings.

The first time I baked these it was for a neighborhood potluck and I barely got to try one because the whole tray disappeared so fast I have learned to make a double batch if I want leftovers

Ingredients

  • All purpose flour: gives the bars structure and a tender crumb Look for unbleached flour for best texture
  • Baking powder and baking soda: help the bars rise and keep them light Check the date to be sure they are fresh
  • Salt: balances sweetness and lets the spices shine Use fine sea salt for even mixing
  • Ground cinnamon: adds signature warming flavor Choose a fragrant fresh jar for maximum aroma
  • Nutmeg and ground ginger (optional): lend extra warmth and complexity Freshly grated nutmeg makes a big difference
  • Vegetable oil: keeps the bars extra moist Neutral oils like canola or sunflower work well
  • Granulated sugar and brown sugar: create a soft crumb and deep flavor Use dark brown sugar for a caramel twist
  • Large eggs: bind the batter and help it rise Room temperature eggs work best
  • Vanilla extract: brings out the sweetness and spice Use pure extract for best results
  • Finely shredded carrots: are the star Use sweet crisp carrots and grate them finely by hand for the best texture They add moisture and color
  • Chopped walnuts or pecans (optional): add crunch and nutty flavor Choose fresh nuts and toast for deeper flavor if you like
  • Raisins (optional): for chewy bites Golden or regular raisins both work well
  • Cream cheese: for the frosting should be softened Full fat block style works best for silky texture
  • Unsalted butter: blends into the frosting for richness Let it come to room temperature
  • Powdered sugar: sweetens and provides a fluffy texture to the frosting Sift if lumpy
  • Vanilla extract (for the frosting): ties all the flavors together again

Step by Step Instructions

Prep the Pan and Oven:
Set your oven to 350 degrees Fahrenheit and let it come fully to temperature for consistent baking. Line your nine by thirteen inch pan with parchment after greasing it so the bars lift out easily.
Mix the Dry Ingredients:
In a medium bowl vigorously whisk together the flour baking powder baking soda salt cinnamon nutmeg and ginger if you are using it This helps evenly distribute the leaveners and spices for even flavor.
Combine the Wet Ingredients:
In a large bowl whisk together the oil granulated sugar brown sugar eggs and vanilla extract until completely smooth. This step gives the bars a silky texture because the sugar dissolves into the oil and eggs.
Bring Dry and Wet Mixes Together:
Add the dry ingredients to the wet bowl in two or three batches stirring gently between each addition until just combined Do not overmix as this could make the bars tough.
Fold in the Carrots and Extras:
Use a spatula to gently fold in the freshly grated carrots and if you like the chopped nuts and raisins Make sure the carrots are evenly spread through the batter for even moisture.
Bake the Bars:
Pour the batter into your prepared pan and smooth the top Bake for twenty five to thirty minutes. The bars are done when the edges are golden and a toothpick inserted in the center comes out clean
Cool Completely:
Let the bars cool fully in the pan on a wire rack. This sets the texture and prevents the frosting from melting
Make the Cream Cheese Frosting:
In a clean bowl beat the softened cream cheese and unsalted butter together on medium speed until silky and smooth Gradually add powdered sugar and vanilla extract beating until fluffy and light
Frost the Bars:
Once the bars are totally cool spread the frosting thickly over top using a spatula for swirls or smoothness
Cut and Serve:
Slice the frosted bars into squares while still in the pan and gently lift each one out Ready to enjoy
