Ingredients You’ll Need

• 1 ¾ cups light brown sugar: This adds deep sweetness and helps create that luscious moist texture. If you don’t have brown sugar, you can use granulated sugar, though the taste may vary slightly.
• 3 large eggs (room temperature): Eggs help bind the ingredients and provide structure. Room temperature eggs blend better into the mixture.
• ¾ cup vegetable oil: Oil keeps the bars moist. You can substitute it with melted coconut oil for a different flavor profile.
• 2 teaspoons vanilla extract: Adds a lovely background flavor that enhances the sweetness. Always opt for pure vanilla extract for the best taste.
• 2 cups all-purpose flour (spooned and leveled): This is the base of your bars. For a gluten-free version, you can use a gluten-free baking blend, but ensure it contains xanthan gum.
• 1 ½ teaspoons baking powder: Helps the bars rise beautifully as they bake.
• ¾ teaspoon baking soda: Provides additional lift and helps balance the acidity from the carrots.
• ½ teaspoon salt: Enhances flavors and balances the sweetness in the bars.
• 2 teaspoons ground cinnamon: Adds warmth and depth—carrot cake is nothing without a good amount of spice.
• ¾ teaspoon ground ginger: The warm heat from ginger complements the sweetness remarkably well.
• ¼ teaspoon ground nutmeg: A pinch of nutmeg brings out the flavors of the other spices perfectly.
• 2 ¼ cups finely shredded carrots: Freshly shredded carrots provide moisture and a sweet crunch. Avoid pre-shredded carrots; use the fine side of a box grater for best results.
• 8 ounces full-fat cream cheese (softened): The main ingredient in your frosting, it lends a tangy contrast to the sweetness of the cake.
• 2 tablespoons butter (softened): Adds additional creaminess to the frosting.
• 2 cups powdered sugar: Sweetens the frosting to perfection—gradually add to avoid a sugar cloud!
• 1 teaspoon vanilla extract: For a richer frosting flavor, just like in the cake.
• ⅛ teaspoon salt: Balances the sweetness and enhances the frosting’s flavor.

How to Make Classic 9×13 Carrot Cake Bars

1. Preheat the Oven: Begin by preheating your oven to 350°F (177°C). Prepare a 9×13-inch baking pan by greasing it, and if you’d like easy removal later, line it with parchment paper.
2. Mix Wet Ingredients: In a large mixing bowl, whisk together the 1 ¾ cups light brown sugar and the 3 large eggs for about a minute until it becomes frothy. Then, add the ¾ cup vegetable oil and 2 teaspoons vanilla extract. Continue whisking for another minute until smooth and slightly thickened.
3. Combine Dry Ingredients: In a separate bowl, whisk together the 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 to combine thoroughly.
4. Mix Dry Into Wet: Carefully fold the flour mixture into the wet ingredients until you see just a few streaks of flour. Make sure to scrape the sides and bottom of the bowl but avoid overmixing for the best texture.
5. Add Carrots: Gently fold in the 2 ¼ cups finely shredded carrots, breaking up any clumps as needed. Once incorporated, spread the batter evenly into the prepared baking pan.
6. Bake: Place your cake batter in the oven and bake for 28-32 minutes. You’ll know they’re done when the edges look set, and a toothpick inserted into the center comes out with a few moist crumbs.
7. Cool Completely: Allow the bars to cool completely in the pan before froasting. Patience is key here; it’s easier to frost when they’re completely cooled!
8. Frosting Preparation: For the creamy frosting, beat 8 ounces of softened full-fat cream cheese until smooth and creamy. Gradually add 2 cups of powdered sugar while mixing, then blend in 1 teaspoon vanilla extract and ⅛ teaspoon salt until the frosting is light and spreadable.
9. Frost Cake Bars: Once the cake bars are completely cool, spread the cream cheese frosting evenly on top. Feel free to get creative with toppings like chopped nuts or additional shredded carrots for an extra touch.

Storing & Reheating

For optimal freshness, store your carrot cake bars at room temperature in an airtight container for up to 2 days. If you want to keep them longer, transfer to the fridge where they can last for up to a week. You can also freeze them for up to three months. Just make sure to wrap them tightly in plastic wrap and then aluminum foil. To enjoy later, simply thaw them in the fridge overnight, and if you’d like, warm them in the microwave for a few seconds to refresh their texture.

Chef’s Helpful Tips

• Room Temperature Ingredients: Always ensure your eggs and cream cheese are at room temperature for the best mixing results.
• Avoid Overmixing: Overmixing the batter can result in dense cake bars. Mix just until combined with visible flour streaks.
• Moisture Check: If your carrots are particularly juicy, consider patting them down with a paper towel before adding to the batter.
• Frosting Variations: Feel free to add a pinch of cinnamon or some lemon zest to the frosting for a delightful twist.
• Make Ahead: You can prep and bake the cake bars a day in advance; just frost them right before serving, ensuring they stay fresh.
