Ingredients

Cupcakes

1 cup all-purpose flour
⅓ cup unsweetened cocoa powder
¾ cup granulated sugar
¼ cup dark brown sugar (light brown works too)
1 teaspoon baking powder
½ teaspoon baking soda
½ cup buttermilk (room temperature)
¼ cup vegetable oil
1 large egg (room temperature)
1 teaspoon vanilla extract
½ cup hot water
black food dye

Buttercream Frosting

1 cup unsalted butter (room temperature)
2 cups powdered sugar
1 teaspoon vanilla extract
1 tablespoon heavy whipping cream
Pinch of salt

Edible Fake Blood

¼ cup strawberry jam
½ tablespoon water
Red & black food coloring

Instructions

Step 1: Prepare the black chocolate cupcakes

Preheat your oven to 350°F (175°C). Line a muffin pan with cupcake liners.
In a large bowl, whisk together the flour, cocoa powder, granulated sugar, brown sugar, baking powder, and baking soda.
In a separate bowl, whisk the buttermilk, vegetable oil, egg, and vanilla extract until smooth.
Combine the wet and dry ingredients, mixing until just combined.
Slowly add the hot water and a few drops of black dye, stirring gently (be careful not to splash!).
Fill cupcake liners halfway with batter.
Bake for 18-20 minutes, or until a toothpick inserted in the center comes out clean.
Let cupcakes cool completely before frosting.

Step 2: Make the Fake Blood

In a microwave-safe bowl, mix the strawberry jam and water.
Microwave for 20 seconds, then stir.
Add one drop of red food coloring and half a drop of black food coloring, then mix until you achieve a deep blood-red color. Set aside.

Step 3: Prepare the Frosting

Using a hand or stand mixer with a paddle attachment, beat the butter for 2 minutes until it becomes pale and creamy.
Add the vanilla extract and salt, mixing well.
Gradually add the powdered sugar while mixing on low speed.
Pour in the heavy cream and increase the speed to medium-high, whipping for 4 minutes until light and fluffy.

Step 4: Assemble & Decorate

Transfer the frosting into a piping bag fitted with a large star tip.
Pipe a swirl of frosting onto each cupcake.
Drizzle fake blood over the frosting using a spoon.
Serve and enjoy the black chocolate cupcakes.

Tips for Success

Don’t Overmix – Stir until ingredients are just combined for the best texture.
Use Room-Temperature Ingredients – This ensures a smoother batter and better cupcake rise.
Chill the Fake Blood – Letting it sit for a few minutes thickens it slightly for a more realistic blood effect.
Experiment with Flavors – Try raspberry jam instead of strawberry for a different taste.
