Carrot Layer Cakefrom Bridget Lancaster, Julia Collin Davison
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.
1 3/4 cups (8.5 ounces) all purpose flour
2 teaspoons baking powder
1 1/2 teaspoons ground cinnamon
3/4 teaspoon ground nutmeg
1/2 teaspoon salt
1/4 teaspoon ground cloves
1 1/4 cups packed (8.75 ounces) light brown sugar
3/4 cup vegetable oil
3 large eggs
1 teaspoon vanilla extract
2 2/3 cups shredded carrots (4 carrots)
2/3 cups currants
16 tablespoons unsalted butter, softened
3 cups (12 ounces) confectioners' sugar
1/3 cup buttermilk powder
2 teaspoons vanilla extract
1/4 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 overn rack to middle position and heat oven to 350 degrees. Grease 18 by 13-inch rimmed baking sheet, line with parchment paper, and grease parchment. Whisk flour, baking powder, baking soda, cinnamon, nutmeg, salt and cloves together in large bowl.
2. Whisk sugar, oil, eggs and vanilla together until mixture is smooth. Stir in carrots and currants. Add flour mixture and fold with rubber spatula until mixture is just combined.
3. Transfer the batter to prepared baking sheet and smooth surface with offset spatula. Bake until center of cake is firm to touch, 15 to 18 minutes. Cool in pan on wire rack for 5 minutes. Invert cake onto wire rack (do not remove parchment) and then reinvert onto second wire rack. Cool cake completely, about 30 minutes.
4. For the Frosting: Using stand mixer fitted with paddle, beat butter, sugar, buttermilk powder, vanilla and salt 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 cake and parchment in half crosswise and then lengthwise to make 4 equal rectangles, about 6-8 inches each.
6. Place 6 by 8-inch cardboard rectangle on cake turntable or plate. Place 1 cake rectangle, parchment side up, on cardboard and carefully remove parchment. Using offset spatula, spread 3/4 cup frosting evenly over cake layer. Repeat with two more layers of cake, frosting each layer with 2/3 cup frosting and pressing gently on each layer to level. Place last rectangle of cake on top and frost top of cake with 1 cup frosting. Use remaining frosting to coat sides of cake. (it's fine if some crumbs show through frosting on the 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.
