  • 1 teaspoon vanilla extract

Equipment

  • To create this dark masterpiece, gather the following:
  • Two 9-inch round cake pans
  • Electric mixer or stand mixer
  • Mixing bowls (large, medium, small)
  • Whisk and spatula
  • Sifter (for cocoa and flour)
  • Cooling racks
  • Measuring cups and spoons
  • Saucepan (for blackberry reduction)
  • Offset spatula or butter knife (for frosting)
  • Optional: Cake turntable for easy decorating.

Method
 

Step 1: Make the Blackberry Reduction
  1. In a small saucepan, combine 2 cups blackberries, lemon juice, and 1 tablespoon sugar.
  2. Simmer over medium heat for 10 minutes, stirring occasionally, until berries break down.
  3. Mash gently, then strain through a fine sieve to remove seeds.
  4. Set aside to cool — this will add natural sweetness and color to the frosting.
Step 2: Prepare the Cake Batter
  1. Preheat oven to 350°F (175°C).
  2. Grease and line two 9-inch cake pans with parchment paper.
  3. In a large bowl, whisk together flour, black cocoa, cornstarch, baking powder, baking soda, and salt.
  4. In another bowl, beat sugar, eggs, buttermilk, canola oil, and vanilla until smooth and creamy.
  5. Slowly add the dry ingredients to the wet mixture, mixing on low until combined.
  6. Stir in hot coffee and ¼ cup water — the batter will be thin, but that’s what makes it ultra-moist.
Step 3: Bake the Cake
  1. Pour batter evenly into prepared pans.
  2. Bake for 30–35 minutes, or until a toothpick comes out clean.
  3. Cool in pans for 10 minutes, then transfer to wire racks to cool completely.
Step 4: Make the Blackberry Cream Cheese Frosting
  1. In a large mixing bowl, beat butter and cream cheese until smooth and fluffy (about 2 minutes).
  2. Add vanilla extract and blackberry reduction; mix until incorporated.
  3. Gradually sift in powdered sugar, beating until light and creamy.
  4. If you want a darker hue, mix in 1 tablespoon black cocoa or a drop of black food gel.
Step 5: Assemble the Cake
  1. Level the cooled cakes if needed.
  2. Spread a thick layer of blackberry frosting between the cake layers.
  3. Frost the top and sides, smoothing evenly with an offset spatula.
  4. Chill for 30 minutes to set before decorating.
Step 6: Decorate the Forbidden Beauty
  1. Arrange chocolate skulls and fresh blackberries on top.
  2. Sprinkle with dried rose petals and lightly dust with powdered sugar for a gothic snow effect.
  3. Optional: place a cinnamon stick or two for a rustic, eerie touch.
  4. Your cake will look like something right out of a dark fairy tale — mysterious, elegant, and completely irresistible.

❓ 10 FAQs

It enhances the chocolate flavor — you won’t taste the coffee itself, but it deepens richness.
