There’s something about a moist, spiced Carrot Cake Sheet Cake that feels like a warm hug on a plate. It’s tender, packed with shredded carrots and warm cinnamon, and topped with the creamiest cream cheese frosting you can imagine.
I baked my first sheet version back in 2021 for a potluck, and I’ll never forget watching it disappear in under ten minutes someone even asked if I’d used a secret ingredient. The trick? Buttermilk keeps it ridiculously soft, and baking it flat means more frosting coverage. After testing this dozens of times as a food blogger, I promise it’s foolproof and feeds a crowd without the fuss of layering.
Carrot Cake Sheet Cake Recipe Easy and Delicious
Ingredients
Method
- Set your oven to 325°F (161°C) convection and grease plus line a 9×13 inch baking pan.
- In a mixing bowl, combine the flour, baking powder, baking soda, salt, and cinnamon thoroughly.
- In a separate large bowl, whisk together the oil and both sugars until smooth, then add the eggs and sour cream, mixing well.
- Carefully fold in the dry flour mixture just until it is incorporated.
- Add the shredded carrots, chopped pecans, lemon zest, and juice, gently folding until evenly mixed.
- Pour the batter into your prepared pan and bake for about 45 minutes or until the cake springs back when lightly pressed.
- Allow the cake to cool fully before applying frosting.
- For the frosting, beat the butter, cream cheese, and vanilla at medium-high speed for 1 to 2 minutes until well mixed, scraping the bowl as needed.
- Add the salt and powdered sugar gradually, mixing first on low speed just to combine, then increase to medium-high and beat for 5 minutes until smooth and no longer gritty.
- If the frosting feels too soft, chill it for 10-15 minutes, stir, then chill again for another 10-15 minutes.
- To assemble, spread one third of the frosting on the first cake layer placed on a flat surface, then add the second layer and refrigerate for 30 minutes to firm up.
- Next, apply a thin crumb coat of frosting over the chilled cake and return it to the fridge for 15-30 minutes until set.
- Use the remaining frosting to cover the cake smoothly with an offset spatula, using a turntable and a scraper for a polished look.
- Finish by sprinkling chopped pecans on top for a crunchy garnish.
Notes
- For best results, ensure all refrigerated ingredients are at room temperature before starting. Store any leftover cake covered in the fridge for up to 4 days. This cake also freezes well if wrapped tightly.

The carrots, pecans, and lemon get stirred in last so they stay evenly distributed without overmixing the batter.
Once it’s in the oven, your kitchen will smell like a cinnamon dream. The cake bakes low and slow at 325°F, which keeps it from drying out. When it springs back lightly in the center, it’s doneno need to overbake.

Frosting Tips & Timing
The cream cheese frosting is where this cake really shines. After years of testing frostings, I’ve learned that beating it for a full five minutes is essentialit transforms grainy powdered sugar into something cloud-like and smooth. If it feels too soft to spread, pop it in the fridge for 10–15 minutes, stir, and chill again briefly.
For the smoothest finish, apply a thin crumb coat first, chill the cake until firm, then spread the final layer. Use an offset spatula and a light handit doesn’t have to be Instagram-perfect to taste incredible.

FAQs (Carrot Cake Sheet Cake)
How long does this cake stay fresh?
This recipe stays perfectly moist for up to 4 days at room temperature when covered tightly. For longer storage, refrigerate for up to a week or freeze unfrosted cake for up to 3 months. The cream cheese frosting helps keep it extra tender and delicious.
Can I make this recipe ahead of time?
Absolutely! You can bake the unfrosted cake up to 2 days ahead and store it covered at room temperature. The frosting can be made 3 days in advance and refrigerated. Just bring the frosting to room temperature before spreading for the smoothest application.
What size pan works best for sheet cake?
A standard 9×13 inch metal baking pan gives the perfect thickness and even baking. Glass pans work too but may need 5-10 extra minutes. Make sure to grease and flour the pan well, or line with parchment paper for easy removal.
Should I peel carrots before grating?
Yes, always peel carrots before grating for the best texture and appearance. Use a box grater or food processor for consistent, fine shreds. Fresh carrots work much better than pre-shredded bags, which tend to be dry and create a less tender cake.
Why is my cream cheese frosting runny?
Runny frosting usually happens when the cream cheese or butter is too warm, or if you overmix it. Make sure both are at cool room temperature, not soft or melty. If it gets runny, chill the frosting for 30 minutes and whip briefly to restore the proper consistency.
