Carrot Sheet Cake

If you love carrot cake but don’t feel like stacking layers and fussing with frosting, this carrot sheet cake is exactly what you need. It has all the warm spices and soft texture you expect, baked in a simple 9×13-inch pan and finished with swoopy browned butter cream cheese frosting.

I love a tall, layered carrot cake, but most of the time I just want something I can bake, frost, and slice without overthinking it. This version has the same familiar flavor, just in a simpler, more relaxed format. (If you love carrot cake in smaller, handheld form, you might also enjoy my carrot cake muffins, which have a similar soft texture.)

It’s easy, unfussy, and just right for spring gatherings, Easter, or any time you want a cozy, crowd-pleasing dessert without the extra work.

Why You’ll Love This Carrot Sheet Cake Recipe

• All the flavor of classic carrot cake — none of the fuss. No layering. No assembling. Just bake, cool, and frost.
• Soft, tender, and perfectly spiced. Finely shredded carrots melt right into the crumb, giving you moisture without chunky texture. Cinnamon leads the way, with just enough nutmeg and ginger to keep it interesting.
• Oil + butter for the best of both worlds. Oil keeps the cake tender for days, while butter adds richness and flavor.
• Browned butter cream cheese frosting. This is what makes this version stand out. Browning the butter adds a subtle nutty warmth that pairs beautifully with the spices and carrots while still tasting unmistakably like classic cream cheese frosting.
• Baked in a 9×13-inch pan. Easy to slice, easy to transport, easy to share.

Key Ingredients and Why They Matter

Let’s take a closer look at what makes this carrot sheet cake so soft and flavorful.

• Finely shredded carrots – The finer the shred, the more they disappear into the cake. You’ll get moisture and flavor without noticeable texture.
• Brown sugar – Adds depth and a little extra moisture alongside the granulated sugar.
• Buttermilk – Just enough to give the cake tenderness and balance the sweetness.
• Neutral oil + melted butter – Oil keeps the crumb soft for days, while butter adds richness.
• Browned butter – Browning the butter before adding it to the frosting deepens the flavor and gives the frosting a subtle caramel-like warmth.

How to Make Carrot Sheet Cake

Whisk the dry ingredients thoroughly.
Make sure the spices and leavening are evenly distributed so every bite has balanced flavor.

Mix just until combined.
Once you add the wet ingredients to the dry, stir gently. Overmixing can make the cake dense.

Fold in the carrots last.
This keeps the batter light and prevents overworking it.

Bake just until done.
The center should spring back lightly when touched, and a tester should come out clean or with a few moist crumbs.

Cool completely before frosting.
Cream cheese frosting will soften quickly on a warm cake, so patience here makes a difference.

Brown butter cream cheese frosting

I adore classic cream cheese frosting, so I didn’t want to change it too much but rather just give it a little depth. Browning the butter does exactly that. It only takes a few extra minutes, but it transforms the frosting.

Cook the butter until the milk solids turn deep golden and smell nutty. Chill it until it’s opaque and just starting to firm up. It should be soft but scoopable. That texture makes it easier to whip smoothly with the cream cheese.

The result is creamy, lightly nutty, and just a little more special than traditional cream cheese frosting without feeling over-the-top.

If you prefer a completely classic approach, you can always use a traditional cream cheese frosting recipe like I pair with my red velvet sheet cake.

Variations and Serving Ideas

• Add raisins or coconut. Stir in ½ cup with the carrots if you like a little extra texture.
• Toast the nuts first. A quick 5 -8 minutes in the oven deepens the flavor. If you want more guidance, see my tips for toasting nuts.
• Skip the nuts altogether. Prefer a smoother crumb? Simply leave them out.
• Keep the frosting classic. If you’d rather not brown the butter, you can use a traditional cream cheese frosting instead.
• Serve it slightly chilled or at room temperature. For clean slices, cut it chilled. For the softest texture and fullest flavor, let it sit at room temperature for about 20–30 minutes before serving.
• Make it part of a spring dessert spread. Pair this cake with something bright and citrusy like my lemon sheet cake or a berry-filled favorite like Chantilly cake for a beautiful spring or Easter dessert table.

How to Store

Because of the cream cheese frosting, this cake should be refrigerated once frosted. Because of the oil in the cake, it stays moist even after refrigeration. Store covered in the refrigerator for up to 4 days. Let slices sit at room temperature for about 20–30 minutes before serving for the best texture.

You can also freeze the unfrosted cake (well wrapped) for up to 2 months. Thaw overnight in the refrigerator before frosting.

Carrot Cake, Made Simple

Sometimes you just want carrot cake without turning it into a project.

This carrot sheet cake gives you all the cozy flavor of the classic version — tender crumb, warm spices, cream cheese frosting — but in the simplest possible form. And that browned butter frosting? It’s the kind of small upgrade that makes people ask what you did differently.

Bake it for a holiday, a potluck, or a random Tuesday. Honestly, this is the kind of cake I’ll happily bake on a random weekend — no special occasion required.
