Ingredients for this Decadent Carrot Cake Bars with Cream Cheese Frosting
For the Carrot Cake Bars:
- 2 cups finely grated carrots (about 4 medium carrots)
- 1 1/4 cups all-purpose flour
- 1/2 teaspoon baking soda
- 1/2 teaspoon baking powder
- 1/4 teaspoon salt
- 1 teaspoon ground cinnamon
- 1/4 teaspoon ground nutmeg
- 2/3 cup light brown sugar, packed
- 2 large eggs
- 1/2 cup vegetable oil
- 1 teaspoon vanilla extract
- 1/2 cup crushed pineapple, drained
- 1/2 cup chopped walnuts or pecans (optional)
For the Cream Cheese Frosting:
- 8 oz cream cheese, softened
- 1/4 cup unsalted butter, softened
- 1 1/2 cups powdered sugar
- 1 teaspoon vanilla extract
- A handful of chopped pecans for garnish (optional)

Step 1: Prep Your Ingredients
Preheat your oven to 350°F (175°C). Grease and line an 8×8 inch baking pan with parchment paper. Grate the carrots finely and drain the crushed pineapple thoroughly.
Step 2: Mix the Dry Ingredients
In a medium bowl, whisk together flour, baking soda, baking powder, salt, cinnamon, and nutmeg. Set aside.
Step 3: Blend the Wet Ingredients
In a large bowl, beat together the eggs, brown sugar, oil, and vanilla extract until well combined. Stir in the grated carrots and crushed pineapple.
Step 4: Combine Wet and Dry
Gently fold the dry mixture into the wet ingredients until just incorporated. If using, add chopped nuts at this stage.
Step 5: Bake the Bars
Pour the batter into the prepared baking pan and smooth the top with a spatula. Bake for 30-35 minutes or until a toothpick inserted in the center comes out clean. Let it cool completely in the pan.
Step 6: Make the Cream Cheese Frosting
In a mixing bowl, beat the softened cream cheese and butter until smooth. Gradually add powdered sugar and vanilla extract, beating until fluffy and spreadable.
Step 7: Frost and Garnish
Spread the frosting evenly over the cooled bars. Sprinkle with chopped pecans if desired. Chill slightly before slicing into bars for clean edges.
How finely should I grate the carrots?
Use the fine side of a box grater. Finer carrots blend better into the batter and make the bars moist.
Can I use pre-shredded carrots from the store?
You can, but freshly grated carrots yield better moisture and flavor. Pre-shredded varieties are usually too coarse and dry.
What can I substitute for crushed pineapple?
Applesauce is a good substitute. Use the same amount (1/2 cup), but expect a slightly different flavor.
Do I need to use nuts?
No, nuts are optional. They add crunch and flavor but can be left out or replaced with raisins or shredded coconut.
Can I double this recipe for a larger batch?
Yes, double all ingredients and bake in a 9×13-inch pan. Add 5-10 extra minutes to the baking time and check with a toothpick.
How do I get neat, clean slices?
Chill the bars before cutting and use a sharp, clean knife. Wipe the blade between cuts for tidy edges.
