Number Of Ingredients 15

1 stick (1/2 cup) unsalted butter, melted, plus more for pans
2 cups unbleached all-purpose flour, plus more for pans
2 teaspoons baking soda
1/2 teaspoon baking powder
2 teaspoons ground cinnamon
1/2 teaspoon ground ginger
3/4 teaspoon kosher salt
2 cups packed light-brown sugar
2 large eggs
4 Granny Smith apples, peeled, two coarsely grated and two sliced
3 sticks (1 1/2 cups) unsalted butter, room temperature
1 1/2 pounds (three 8-ounce bars) cream cheese, room temperature
5 cups confectioners' sugar, sifted
2 pinches kosher salt
Apple chips, for garnish (optional)

Steps:

Cake: Preheat oven to 350 degrees. Butter three 8-inch round cake pans; line with parchment. Butter and flour parchment, tapping out any excess.
In a medium bowl, whisk together flour, baking soda, baking powder, cinnamon, ginger, and salt. In a large bowl, whisk together butter, brown sugar, and eggs until well combined; fold in grated and diced apples. Add flour mixture; mix just until combined. Divide batter among prepared pans; smooth tops.
Bake until a tester inserted in centers comes out clean, 35 to 40 minutes. Let cakes cool in pans 20 minutes, then invert onto wire racks; remove parchment. Invert cakes again; let cool completely on racks.
Frosting: In the bowl of a mixer fitted with the paddle attachment, beat butter on medium-high speed until fluffy, about 2 minutes. Add cream cheese and beat until well combined and fluffy, about 2 minutes more. Add confectioners' sugar and salt; beat 5 minutes.
Place a cake layer on a serving plate. Spread about 1 cup frosting evenly over it; top with a second cake layer. Repeat with another 1 cup frosting and third cake layer. Spread remaining frosting over top and sides of cake. Refrigerate at least 1 hour and up to 4 days. Return to room temperature before serving. Garnish with apple chips, if desired; use a serrated knife to slice cake.
