Ingredients

10 tablespoons (1 1/4 sticks) unsalted butter, melted, plus more softened for pans 

2 tart apples (1 pound total), such as McIntosh or Granny Smith 

1/4 teaspoon ground cinnamon 

1/4 teaspoon ground nutmeg 

1 tablespoon granulated sugar 

1 cup plus 1 tablespoon packed light-brown sugar 

1 cup all-purpose flour 

1/2 teaspoon coarse salt 

1 large egg, lightly beaten 

1 cup walnut halves (about 3 1/2 ounces), toasted and coarsely chopped 

Preparation

Preheat oven to 350 degrees. Butter three 5 3/4-by-3 1/4-inch nonstick straight-sided mini loaf pans. Peel, core, and cut apples into 1/4-inch-thick wedges; transfer to a medium bowl. Add spices and granulated sugar; toss. Arrange in a line down center of pans so that apples stand upright.

Whisk brown sugar, flour, and salt in a large bowl. Add egg and butter; whisk until just combined. Stir in walnuts. Pour batter over apples in pans. Smooth top.

Bake until tops are deep golden brown and a cake tester inserted into centers comes out clean, 35 to 40 minutes. Let cool slightly in pans on wire racks, about 25 minutes. Run a knife around edges of cakes to loosen, and turn out each onto a large plate. Using a serrated knife, cut each cake into 6 slices, and serve.
