Ingredients
  

Chocolate Cake
  • 2 cups all purpose flour
  • 2 cups granulated sugar
  • ¾ cup unsweetened cocoa powder
  • 1½ tsp baking powder
  • 1½ tsp baking soda
  • 1 tsp fine salt
  • 2 large eggs
  • 1 cup whole milk
  • ½ cup vegetable oil
  • 2 tsp vanilla extract
  • 1 cup boiling water
Orange Buttercream
  • 1 cup unsalted butter softened
  • 3½ to 4 cups powdered sugar sifted
  • ¼ cup milk or heavy cream plus 1 to 3 tbsp more as needed
  • 2 tsp vanilla extract
  • Pinch of fine salt
  • Orange gel food color
  • Decorations
  • Halloween sprinkles candy eyes, mini pumpkins, or gummy bats

Equipment

  • Two 9 inch round cake pans, lined and greased
  • Mixing bowls, large and medium
  • Hand mixer or stand mixer
  • Measuring cups and spoons
  • Whisk and rubber spatula
  • Wire racks
  • Offset spatula and bench scraper
  • Piping bags and round or star tips, optional
  • Parchment paper

Method
 

Method
  1. Heat oven to 350°F. Grease two 9 inch pans, line bases with parchment, and lightly flour sides.
  2. In a large bowl whisk flour, sugar, cocoa, baking powder, baking soda, and salt.
  3. In another bowl whisk eggs, milk, oil, and vanilla. Pour wet into dry and beat 1 to 2 minutes until smooth.
  4. Carefully whisk in boiling water. Batter will be thin. Divide evenly between pans.
  5. Bake 30 to 35 minutes until a toothpick comes out with a few moist crumbs. Cool 10 minutes in pans, then turn out to racks to cool completely.
  6. Make the buttercream. Beat butter until pale and fluffy, 2 to 3 minutes. Add 3½ cups powdered sugar, salt, vanilla, and ¼ cup milk or cream. Beat on low to combine, then on medium high until light and smooth, 2 to 3 minutes. Adjust with more sugar for thickness or a splash of milk for softness. Tint to a vivid orange with gel color.
  7. Level cake layers if needed. Place one layer on a board, add a generous layer of buttercream, top with the second layer, and crumb coat. Chill 15 minutes, then apply a smooth final coat.
  8. Decorate with sprinkles and candies or halloween decorations. Pipe small swirls or borders if you like. Chill 10 minutes to set before slicing.

Tips & Variations

  • Sheet cake option, bake in a 9 by 13 inch pan for 30 to 35 minutes and frost the top only.
  • Flavor twist, add 1 tsp espresso powder to the dry ingredients for richer chocolate.
  • Color control, use gel color (not liquid) for bright orange without thinning the frosting.
  • Make ahead, bake layers 1 day ahead, wrap and chill. Frost day of or the evening prior.

FAQ

Q: Can I make the frosting black instead of orange.  
A: Yes. Use black gel color or black cocoa buttercream. If using gel, start with a dark chocolate base so you need less dye.
Q: How do I keep crumbs out of the frosting.  
A: Apply a thin crumb coat and chill 15 minutes before your final coat. Work with a slightly chilled cake and a soft, spreadable buttercream.
Q: Will the colors bleed onto the candy.  
A: Gel colors are stable, but moisture makes sprinkles bleed. Decorate close to serving time if using gummy candies, or store the finished cake loosely covered in a cool room.
Q: Can I freeze it.  
A: Freeze unfrosted layers up to 2 months, well wrapped. Thaw overnight in the fridge, then frost.
Q: How should I transport the cake.  
A: Chill the frosted cake 20 to 30 minutes to firm the buttercream, place in a snug cake carrier, and keep flat during travel.
