Description

This professional-grade Devil’s Food Layer Cake features a robust, structurally sound crumb and an intense depth of flavor achieved through a precise Dutch-processed cocoa and hot coffee bloom. Engineered for clean slicing and perfect stacking, this cake delivers a moist, tender interior paired with a sophisticated, rich chocolate profile.


Ingredients

  • All-purpose flour
  • Baking soda
  • Baking powder
  • Fine sea salt
  • Unsalted butter, room temperature
  • Granulated sugar
  • Light brown sugar
  • Dutch-processed cocoa powder
  • Vegetable oil
  • Eggs
  • Vanilla extract
  • Milk
  • Sour cream
  • Hot coffee


Instructions

  1. Prepare pans. Preheat the oven to 350°F and grease two 9-inch round pans, lining the bases with parchment paper and dusting with flour.
  2. Sift dry ingredients. Combine and sift the all-purpose flour, baking soda, baking powder, and fine sea salt at least twice to ensure even aeration.
  3. Cream fat and sugar. Beat room-temperature butter with granulated and light brown sugars in a stand mixer until pale and fluffy.
  4. Emulsify cocoa paste. Whisk Dutch-processed cocoa powder and vegetable oil in a separate bowl until smooth before adding to the butter mixture.
  5. Incorporate eggs. Add eggs one at a time, beating for 30 seconds after each addition and scraping the bowl to maintain a stable emulsion.
  6. Alternate dry and wet. Mix in one-third of the dry ingredients followed by half of the milk and sour cream mixture, repeating until incorporated.
  7. Add hot coffee. Pour the hot coffee into the batter in a steady stream while mixing on low speed to bloom the cocoa and gelatinize starches.
  8. Bake the layers. Divide batter equally into pans and bake for 40 to 45 minutes until the centers spring back, then cool for 15 minutes before unmolding.
  9. Assemble and frost. Level the cooled cakes, stack with a generous layer of buttercream, and apply a crumb coat before final frosting.

Notes

  • Use a digital kitchen scale to measure ingredients in grams for the most consistent chemical reaction during baking.
  • Ensure all dairy and eggs are at room temperature to prevent the batter from curdling when the cocoa-oil mixture is added.
  • Wrap baked layers tightly in plastic wrap and chill before frosting to create sharper edges and minimize crumbs during assembly.
  • The cake batter will appear quite thin due to the addition of hot coffee; this is normal and essential for achieving a moist crumb.
