Ingredients You’ll Need

1 ¾ cups light brown sugar: Provides moisture and a rich, caramel-like taste that enhances the overall flavor profile. Dark brown sugar can also be used for a deeper flavor.
3 large eggs, room temperature: Eggs help bind the ingredients together and contribute to the cake’s rise. Take them out of the fridge ahead of time for the best results.
¾ cup vegetable oil: This keeps the cake moist and tender. For a healthier option, you can substitute applesauce or melted coconut oil.
2 teaspoons vanilla extract: Enhances the sweetness and adds depth to the cake. Pure vanilla extract is always a better choice than imitation.
2 cups all-purpose flour: This forms the base. Be sure to spoon and level the flour for accuracy; too much flour can make the cake dense.
1 ½ teaspoons baking powder: This leavening agent will help give the bars a nice lift.
¾ teaspoon baking soda: Combines with the acidic ingredients to create lift and lightness in the cake.
½ teaspoon salt: Balances the sweetness and enhances all the flavors.
2 teaspoons ground cinnamon: Adds warmth and a familiar spice note that pairs perfectly with carrots.
¾ teaspoon ground ginger: Offers a slight zing that enhances the overall flavor profile.
¼ teaspoon ground nutmeg: Introduces a warm, nutty flavor that complements the spices beautifully.
2 ¼ cups finely shredded carrots: The star of the show! Freshly grated carrots keep the cake moist and flavorful.
8 ounces full-fat cream cheese, softened: This is the base for our creamy frosting, adding richness and a slight tang.
2 tablespoons butter, softened: Helps to create a smooth, spreadable frosting.
2 cups powdered sugar: Sweetens the frosting while ensuring it’s light and fluffy.
1 teaspoon vanilla extract: The same lovely addition to the frosting brings everything together.
⅛ teaspoon salt: A pinch of salt balances the sweetness in the frosting.

How to Make Classic 9×13 Carrot Cake Bars

Preheat the Oven: Begin by preheating your oven to 350°F (177°C). Prepare a 9×13-inch baking pan by greasing it thoroughly or lining it with parchment paper for easy removal.
Mix the Wet Ingredients: In a large mixing bowl, whisk together the 1 ¾ cups light brown sugar and 3 large eggs until the mixture becomes foamy, about 1 minute. Stir in the ¾ cup vegetable oil and 2 teaspoons vanilla extract, continuing to whisk for another minute until smooth and slightly thickened.
Combine Dry Ingredients: In a separate bowl, whisk together 2 cups all-purpose flour, 1 ½ teaspoons baking powder, ¾ teaspoon baking soda, ½ teaspoon salt, 2 teaspoons ground cinnamon, ¾ teaspoon ground ginger, and ¼ teaspoon ground nutmeg. Ensure all spices are evenly distributed for maximum flavor.
Incorporate Dry Mixture: Gently fold the dry ingredients into the wet mixture. Your goal is to combine them until you see just a few streaks of flour—overmixing can lead to dense bars! Scrape the bottom and sides of the bowl during this process.
Add Carrots: Carefully fold in the 2 ¼ cups finely shredded carrots, breaking up any clumps. This ensures the carrots are evenly distributed throughout the batter.
Spread Into Pan: Pour the batter into your prepared pan. Spread it evenly, ensuring all corners are filled.
Bake: Bake in your preheated oven for 28-32 minutes. Keep an eye out for those edges—they should be set, while the center springs back slightly when touched, and a toothpick inserted should come out with a few moist crumbs.
Cool: Remove your cake bars from the oven and let them cool completely in the pan so you can frost them without melting off all your hard work.
Make the Frosting: In a mixing bowl, beat the 8 ounces of softened cream cheese until smooth and creamy. Gradually add in the 2 cups powdered sugar, then mix in 1 teaspoon vanilla extract and ⅛ teaspoon salt, beating until light and spreadable.
Frost the Cake: Once the cake has cooled, spread your cream cheese frosting evenly over the top.

Storing & Reheating

Store your Classic 9×13 Carrot Cake Bars at room temperature for up to 3 days in an airtight container. If you prefer refrigeration, they can last for about a week, keeping flavors fresh. To freeze, wrap individual bars in plastic wrap followed by aluminum foil, and store them in a freezer-safe container for up to 3 months. When you’re ready to enjoy them again, pop them in the oven at 350°F (177°C) for a few minutes, or let them thaw at room temperature to bring back their delicious texture.

Chef’s Helpful Tips

Avoid overmixing the batter to keep your bars light and fluffy.
Use freshly grated carrots for the best moisture and flavor; pre-shredded carrots can be drier.
Make sure all your wet ingredients are at room temperature for even mixing.
Don’t skip the cooling step before frosting; hot cake will melt your cream cheese frosting!
Feel free to add nuts or raisins to the batter for extra texture and flavor.

Nothing beats the flavors and nostalgia of these bars. The spiced aroma, the tender crumb, and the rich cream cheese frosting come together to create a dessert experience everyone will cherish. You’ll undoubtedly want to share these Classic 9×13 Carrot Cake Bars with family and friends, but don’t forget to save a piece or two just for yourself. Enjoy!

Recipe FAQs

Can I make this recipe ahead of time?

Absolutely! You can bake the bars a day in advance. Just make sure to frost them only after they’ve completely cooled, and keep them covered in the fridge until you’re ready to serve.

How can I make these bars gluten-free?

You can substitute the all-purpose flour with a gluten-free blend that is designed to measure cup-for-cup. Just make sure it contains xanthan gum for the best texture.

What can I use instead of cream cheese in the frosting?

If you’re looking for a healthier option, try a Greek yogurt frosting. Use about 8 ounces of plain Greek yogurt and mix in powdered sugar and vanilla to taste.

Can I add nuts or raisins?

Absolutely! Finely chopped walnuts or pecans add a nice crunch, while raisins offer a touch of sweetness. Add about 1 cup of either to the batter when you fold in the carrots for added texture.
