"Ultimate Carrot Layer Cake" (the cake I made last weekend)

Last edited Thu Sep 11, 2014, 02:09 AM - Edit history (1)










I made this cake primarily to test it and my ability at making it before I make it again in September, for my GF's late birthday celebration.

And, I transcribed the recipe below because one of my friends with whom I shared it was so blown away by the flavor and quality (I was to, to be honest ) that I promised to copy the recipe for her to try. So, I thought I'd share it with y'all, in case you don't have this particular baking book


Ultimate Carrot Layer Cake
(from Cook’s Illustrated Baking Book)


WHY THIS RECIPE WORKS
Building a show-stopping carrot cake comes with plenty of obstacles. The carrots make the cake sticky and prone to breaking. No more than two layers of the moist, heavy cake can be stacked without risk of toppling. And the frosting often gets compromised in the process. We wanted to reengineer humble carrot cake as a four-tier, nut-crusted confection that could claim its place among the most glamorous desserts.

BAKE IN A SHEET PAN
Removing, slicing, and stacking carrot cake from traditional cake rounds was almost impossible. Instead, we decided to bake our cake in a rimmed baking sheet and then stack them into a tall, rectangular cake. This concept has a lot going for it: The cake bakes up quickly and takes only 30 minutes to cool. And because the middle sets almost as quickly as the edges, the cake doesn’t dome.

SOFTEN THE CARROTS
We ran into one issue with our baking sheet method. Thanks to the drastically reduced baking time, the coarse shreds of carrot didn’t have time to soften and they bake up coarse and crunchy. We remedy this by adding some extra alkaline baking soda to the batter. This raises the pH of the cake and breaks down the carrot shreds’ cell walls for softer carrots.

FINESSE THE FROSTING
Cream cheese frosting makes the perfect partner to carrot cake, but we needed it to be thick enough to stay sandwiched between the cake layers. Confectioners’ sugar provides structure, but it can also overshadow the cream cheese’s tanginess. A secret ingredient enabled us to get the best of both worlds: Buttermilk powder lends the frosting a pleasant, cheesy than and also allows us to add as much confectioners’ sugar as we needed without sacrificing flavor.

FINISH WITH NUTS
To make our cake special occasion-ready, we needed to hide the delicate cut sides, which looked messy compared with the pristine top layer. That’s where nuts come in. we had omitted them from the batter because they caught on our knife during slicing. To camouflage the imperfections—and to satisfy tasters who missed the crunch of the pecans in the cake—we press toasted nuts on the crumb-speckled sides.


ULTIMATE CARROT LAYER CAKE
SERVES 10 TO 12

Shred the carrots on the large holes of a box grater or in a food processor fitted with the shredding disk. Do not substitute liquid buttermilk for the buttermilk powder. To ensure the proper spreading consistency for the frosting, use cold cream cheese. If your baked cake is of an uneven thickness, adjust the orientation of the layers as they are stacked to produce a level cake. Assembling this cake on a cardboard cake round trimmed to a 6 by 8-inch rectangle makes it easy to press the pecans onto the sides of the frosted cake.

CAKE
1 ¾ cups (8 ¾ ounces) all-purpose flour
2 teaspoons baking powder
1 teaspoon baking soda
1 ½ teaspoons ground cinnamon
¾ teaspoon ground nutmeg
½ teaspoon salt
¼ teaspoon ground cloves
1¼ cups packed (8 ¾ ounces) light brown sugar
¾ cup vegetable oil
3 large eggs
1 teaspoon vanilla extract
2 2/3 cups shredded carrots (4 carrots)
2/3 cup dried currants

FROSTING
3 cups (12 ounces) confectioners’ sugar
16 tablespoons unsalted butter, softened
1/3 cup buttermilk powder
2 teaspoons vanilla extract
¼ teaspoon salt
12 ounces cream cheese, chilled and cut into 12 equal pieces
2 cups (8 ounces) pecans, toasted and chopped coarse


1. FOR THE CAKE: Adjust oven rack to middle position and hear cover to 350 degrees. Grease 18 by 13-inch rimmed baking sheet, line with parchment paper, and crease parchment. Whisk flour, baking powder, baking soda, cinnamon, nutmeg, salt, and cloves together in large bowl.
2. Whisk sugar, oil, eggs, and vanilla together in second bowl until mixture is smooth. Stir in carrots and currants. Add flour mixture and fold with rubber spatula until mixture is just combined.
3. Transfer batter to prepared sheet and smooth surface with offset spatula. Bake until center of cake is firm to touch, 15 to 18 minutes, rotating pan halfway through baking. Cool in pan on wire rack (do not remove parchment), then re-invert onto second wire rack. Cool cake completely, about 30 minutes.

4. FOR THE FROSTING: Using stand mixer fitted with paddle, beat sugar, butter, buttermilk powder, vanilla, and salt together on low speed until smooth, about 2 minutes, scraping down bowl as needed. Increase speed to medium-low; add cream cheese, 1 piece at a time, and mix until smooth, about 2 minutes.
5. Transfer cooled cake to cutting board, parchment side down. Using sharp chef’s knife, cut the cake and parchment in half crosswise, then lengthwise, to make 4 equal rectangles, about 6 by 8 inches each.
6. Place 6 by 8-inch cardboard rectangle on cake platter. Place 1 cake layer, spread 2/3 cup frosting evenly over top, right to edge of cake. Repeat with 2 more layers of cake, pressing lightly to adhere and frosting each layer with 2/3 cup frosting. Top with last cake layer and spread 1 cup frosting evenly over sides of cake. (It’s fine if some crumbs show through frosting on sides, but if you go back to smooth top of cake, be sure that spatula is free of crumbs.)
7. Hold cake with 1 hand and gently press chopped pecans onto sides with other hand. Chill for at least 1 hour before serving. (The frosted cake can be refrigerated for up to 24 hours before serving.)

Do you have a trick to get the sides so well crusted with nuts? I seem to always have trouble with that, and yours looks so good.

I have a delicious chocolate orange carrot cake that I like to bake. It has a chocolate frosting, instead of cream cheese.

Sat Jun 28, 2014, 01:21 AM

is to hold the cake with one hand (it's on cardboard from a former cake 'round') and over the bowl with the chopped nuts. Grab a handful, and press from the bottom up. You may have to go up the side in increments, and then from the front to the back the same way.

I still had about half a cup of chopped nuts leftover. I did get some frosting on my hand or fingers from time to time, but you just have to ignore that until finished.

One trick I did do for both getting the frosted cake into my hand at all and then back to the platter was to use my offset spatula to lower it. It's pretty strong, so I didn't fear bending or breaking it. I think it's a Dexter brand, probably bought in a restaurant supply store, like AceMart.

And I've got a decent-quality cake-carrier, though I still put a piece of looped-back tape underneath to keep it from slipping during transport. If you don't have a carrier, tape it to a larger cake round in a delivery box (the thin cardboard fold-up kind bakeries use.) And if you don't have to take it somewhere, don't worry about any of that

Would you be able to post your carrot cake recipe? Or what it is that makes it chocolate-orange? That is always a great combination

Or is it flat on the counter while applying the nuts?

I will look for my recipe tomorrow. It's late. But what makes it chocolate orange is basically cocoa powder in the batter, and chopped up canned mandarin oranges added with the carrots. And the frosting is whipped chocolate ganache. It's very good, and loaded with calories. I like to dry a few of the mandarin slices whole, and drizzle them with melted chocolate to decorate the top, in addition to trying to apply nuts to the sides.

I have a strange weakness for cake carriers, I probably have 8-10 different ones. My daughter gave me a cupcake carrier shaped like a cupcake. Transporting a cake without a proper carrier is a real drag.

but have used bakery boxes in the past without problems. There's a great shop here in town that sells nothing but cake-making and -transporting supplies. It's where I get my cake rounds. I'll be looked at their rectangular pieces next time so I don't have to ruin a round to make one for this cake.

Your variation sounds wonderful, and I may have to try it some time. I'll add it to my recipe here as a variation.

Another thing to try in place of the dried mandarins is candied orange peels. I just watched a pretty good show on the Cooking channel (I haven't watch such shows in a while) that's just on sweets. I think it's called "Sweet Julia" and in her debut episode she made candied orange peels differently than the recipes I've used in the past. I'll have to transcribe it or find a youtube clip and post it soon

Yes, I do hold the cake in my hand. The baking book has some nice drawings indicating that part, but I don't have a scanner to post them. Any cake where I have to decorate the sides whether with ganache, frosting, and/or chopped nuts, I assemble it on a cardboard round or rectangle/square. The kind of cardboard made just for that purpose is much stiffer than what you'll find in your typical cardboard box, but you can use that stuff as well. Just be aware it may not be strong enough. In which case, use two layers with the corrugations angled across the other (so that if one layer folds, the other doesn't.)

I have some assembly images I didn't post before, so I'll paste them in here for you to see


First layer with cardboard support



4th (and last) layer before final frosting



Let me know if you need any further help with this

If you try it, and then leave it as a sheet cake, I'd think it would still be just as delicious. Plus you'd be able to put more nuts into the cake recipe. I did anyway, but they were crushed walnuts, so I'd have no trouble cutting the rectangles.

This Cook's Illustrated Baking Book is going to be a favorite of mine, I know that much!

I have adapted to high altitude because I live at 7,000 feet above sea level, in Santa Fe, NM.

I can say that most people get it wrong about the high altitude adjustment, including some professionals I know. It's not hard: reduce the leavening by half. Leave the sugar alone. Increase liquid slightly, which can be done by using larger eggs. Also, add slightly more of the shortening. Reduce the flour by about a tablespoon per cup. The problem with these adjustments is that they're slightly tricky to quantify into exact amounts, and most publishers of recipes want very simple measurements: one cup, one half cup, one teaspoon, one half teaspoon, and so on. It's only in older recipes that you'll find a third of a cup or some such slightly oddball measurement. As a consequence, I've learned that the older recipes are much better, and are actually easier to adjust to high altitude.

The other complaint I have about most high altitude adjustments is that they call for more flour. Excuse me, but we're already in a dry place. You do not want to do anything that makes the resulting product drier. I'm driven crazy by the grocery stores here, even Sprouts and Whole Foods, because apparently they follow the conventional "add more flour" wisdom, and as a consequence the breads they bake are stale a few hours later. It's criminal, because it's not that hard and they get it wrong.

due to CI adding more baking powder as a means of softening the carrot shreds.

I know I've made some stuff that didn't look as good as it tasted, so I understand

The reasoning given in the beginning of the recipe said they did that due to the thinness of the cake, having made sheet cakes without as much and the shreds didn't soften much. Now, the baking time affects that, and this one is only in the oven no more than 18 minutes. If you're cooking yours longer, then that's probably why you wouldn't need something else to help them soften. Plus, these are coarse-shreds, so thinner shreds would soften better, too.

CI is good at figuring out the science of this kind of thing. Maybe you could send them your tips on high-altitude baking of carrot sheet cake

Carrot Cake

4 eggs 3 cups grated carrots
1 ¼ cups vegetable oil 1 cup chopped pecans
2 cups white sugar 2 ½ teaspoons vanilla
2 cups less 2 tablespoons flour ½ teaspoon nutmeg
1 teaspoon baking powder 1 teaspoon baking soda
½ teaspoon salt 2 teaspoons ground cinnamon

Preheat oven to 350 degrees F. Lightly grease a 9x13 pan.

In a large bowl beat together the eggs, oil, sugar, and vanilla. Mix in dry ingredients. Stir in carrots and pecans. Pour into pan. Bake 40-50 minutes. Then let cool for at least a half hour.

Frosting: ½ cup unsalted butter, softened
8 oz cream cheese, softened. Use regular, not whipped or low fat.
4 cups confectioners sugar
1 teaspoon vanilla
1 cup chopped pecans
In a bowl combine the butter, cream cheese, sugar and vanilla. Beat until smooth and creamy, then add the chopped pecans. Frost the cake.

The recipe I printed out tells you to grease and flour the pan, so that after it's cooled you can take it out of the pan to frost. I just lightly grease the pan with Crisco, and leave the cake in the pan. I have already made the high altitude adjustments, so if you want to try this at lower altitude double the baking powder and soda, put the flour back up to two full cups, and reduce the vanilla by a quarter teaspoon in the cake recipe. At high altitude a little more flavoring needs to be added, and I don't know why.

I've never had to bake anything for high-altitude, so it's interesting to see the amounts

Plus, now I see what you mean by a "sheet pan." I don't know the classic name for a 9x13" pan, other than by its dimensions. Whereas, I have two half-sheet pans, measuring 13x18" and maybe 3/4" deep. Something like this:




producing the carrot cake like this:




Now, that same book has a recipe on the following page for a 9x13" cake, so I'll have a look and see how it compares to yours, minus the adjustments. If it looks like something you might want to try, or just read, I'll transcribe it for you

And never, never, never bake cookies on a totally flat pan. The low sides of a cookie sheet are necessary to keep in the right amount of heat to keep the cookie dough from spreading all over.

I use a 9x13 pan with two inch sides. At high altitude if you baked a really thin cake I think it would come out very crunchy because it would dry out terribly.

Also, I often substitute brown sugar for white in a lot of what I bake.

This is the second time in my life I've lived and baked at high altitude. The previous time was in Boulder, which is only 6,000 feet. The thousand feet higher I am here in Santa Fe actually makes a difference. A slight one, but I'm VERY OCD about all of my recipes.

Sun Jun 29, 2014, 11:52 PM

I use them for cookies or sheet-cakes like this one. Basically, it's the same kind of pan you would use to make a typical jelly roll cake. It must be shallow to allow you to roll the final product.

Under "Essential Bakeware" here's what CI has to say about this kind of pan:

Baking Sheets
In the test kitchen, we use baking sheets for baking everything from cookies to jelly rolls and tarts. When buying baking sheets, look for the ones that are light and thick. A light-colored surface will heat and brown evenly, making for perfectly browned baked goods. And a pan that isn't thick enough can buckle or transfer heat too intensely, burning the food. We prefer pans that are 18 by 13 inches with a 1-inch rim all around. Note that a traditional jelly roll pan is smaller than these industrial-sized baking sheets. And because they have so many different uses, we recommend having more than one.

I have two already, and have been thinking of getting a couple more. I've had these two a good fifteen years or more. A full-size sheet pan still has the 1-inch lip, but they measure 18 by 26 inches, way too big for my oven (or most typical home ovens.)

I do have a Pyrex 9 by 13-inch pan (another pan they recommend) which is the kind for your kind of sheet cake. I think I need to look at straight-side metal pans for this size and to replace or compliment my square pans. Eventually, I'll have my kitchen organized to where I know everything I own (other than the eight loaf pans I've acquired or inherited) so I can do almost anything baking-wise

The substitution of brown sugar is probably just right for your high-alt adjustments as it adds both extra moisture and the molasses is good for you. Now I need to look up Gingersnaps because my friends asked about that, giving me an idea of what their mother's cookies were like. Another challenge!

Which is why I need to get some metal square/rectangular pans. I have plenty of round metal pans. I'll have a look when I'm at a local cake-making supply business tomorrow

The only times I've made a jelly roll was in school and at one bakery where I worked for a year. We did a lot of thin cakes there using no more than metal cake rings on the black-metal sheet pans (they had a carbon coating on fairly thick steel, and it acted like a non-stick coating.) I was always amazed at how the batter stayed in the rings and didn't seep under them.
