Ingredients
Method
- Preheat oven to 350°F (175°C). Grease two 9-inch round pans and line bottoms with parchment. Whisk flour, cocoa, sugar, baking powder, baking soda, and salt. Add eggs, buttermilk, oil, and vanilla; beat 2 minutes. Mix in hot coffee on low until just combined.
- Divide batter into pans, tap to release bubbles. Bake 28-32 minutes until a toothpick comes out with moist crumbs. Cool in pans 10 minutes, then turn out and cool completely.
- Beat butter 4 minutes until fluffy. Gradually add powdered sugar, then cream, vanilla, and salt. Beat 2 minutes, then tint with red gel coloring until bright red.
- Place one cake layer on a plate, spread 1 cup frosting, top with second layer. Apply a thin crumb coat, chill 20 minutes, then frost the entire cake red.
- Melt yellow candy melts, pipe curved strings and small dots for lights. Use black icing to pipe letters along the sides. Serve at room temperature.
Notes
The cake layers can be baked a day ahead and wrapped well. Cool them fully before frosting, and give the finished cake at least 30 minutes to come to room temperature after chilling if you store it in the fridge.
