How we chose
Research-backed · reviewed Aug 2026
We matched the required pair, exact nine-inch footprint, uncoated aluminum construction, model 46904AMZ, manufacturer UPC, heat behavior, care burden, and exact Amazon identity. Kwilt has not baked with these pans.
Nordic Ware Naturals 9-Inch Round Cake Pans, Set of 2 · 46904AMZ: The two-pan set matches the recipes' simultaneous layer bake, while uncoated aluminum conducts heat evenly without the dark finish that can overbrown delicate cake edges. Trade-off: Uncoated aluminum needs hand washing and can mark over time; grease and parchment the pans exactly as the recipe directs for clean release.
Another workable path: Use two matching light-colored 9-inch round pans with the same depth; mismatched materials can produce uneven bake times and different browning.

Ingredients

1× recipe · Makes 12 slices

2 cups (240 grams) all-purpose flour
3/4 cup (64 grams) Dutch-process cocoa powder
1 3/4 cups (350 grams) granulated sugar
2 teaspoons baking soda
1 teaspoon baking powder
1 teaspoon fine sea salt
2 large eggs, room temperature
1 cup (240 grams) buttermilk, room temperature
1/2 cup (100 grams) neutral oil
2 teaspoons vanilla extract
1 cup (240 grams) hot coffee or hot water
1 cup (226 grams) unsalted butter, softened
3 1/2 cups (420 grams) confectioners' sugar
2/3 cup (57 grams) Dutch-process cocoa powder, for frosting
1/2 cup (120 grams) heavy cream, as needed
Pinch of fine sea salt, for frosting

Instructions

Heat oven to 350°F. Grease , line bottoms with parchment, and grease again. Whisk flour, 3/4 cup cocoa, granulated sugar, baking soda, baking powder, and 1 teaspoon salt until no cocoa lumps remain.
Whisk in eggs, buttermilk, oil, and vanilla, then slowly whisk in hot coffee; the batter will be thin. Divide evenly between pans and bake 27 to 34 minutes until the tops spring back and a tester shows moist crumbs. Cool 15 minutes in pans, then turn onto racks and cool completely.
For frosting, beat softened butter until creamy. On low, add confectioners' sugar, 2/3 cup cocoa, and the pinch of salt. Beat in cream a tablespoon at a time until spreadable, then beat 2 minutes until lighter; avoid making it so loose that the layers slide.
Set one level cake layer on a plate and spread with about 1 cup frosting. Add the second layer upside down for a flat top. Apply a thin crumb coat, chill 15 minutes, then cover top and sides with remaining frosting. Let stand 20 minutes before slicing.
Store covered at cool room temperature up to 2 days or refrigerate longer; return slices to room temperature before serving so buttercream and crumb soften. If making ahead, wrap unfrosted cool layers airtight and freeze rather than refrigerating them uncovered.

About this recipe

American chocolate layer cake developed through nineteenth- and twentieth-century access to cocoa, chemical leaveners, and dependable home ovens; the moist devil’s-food family emphasizes a tender dark crumb and generous frosting.

This is the familiar American celebration cake often associated with devil's food: dark, deeply chocolatey, and tender rather than brownie-dense. Oil keeps the crumb soft, buttermilk supports flavor and lift, and hot coffee blooms cocoa without making the finished cake taste like coffee. A simple chocolate buttercream supplies the nostalgic layer-cake finish without ganache or pastry components. This Kwilt version follows the reviewed household adaptation: Synthesize the recurring oil-buttermilk-coffee cake architecture with a conventional cocoa buttercream, prioritizing tenderness and reliable assembly over a third chocolate component or elaborate decoration.
