Ingredients:
- 1 ½ cups (192g) all-purpose flour, plus more for dusting
- ¾ cup (75g) unsweetened cocoa powder
- 1 ½ teaspoons baking powder
- ¾ teaspoon baking soda
- ¾ teaspoon salt
- 1 ½ cups (300g) granulated sugar
- ½ cup (120ml) vegetable oil
- 1 ½ teaspoons vanilla extract
- 1 cup (240ml) buttermilk, room temperature
- 2 large eggs, room temperature
- ¾ cup (180ml) boiling water
- 1 cup (226g) unsalted butter, softened
- 4 cups (480g) powdered sugar, sifted
- ¼ cup (60ml) heavy cream
- 1 teaspoon vanilla extract
- Red gel food coloring
- Black gel food coloring (optional)
Instructions:
- Preheat oven to 350°F (175°C). Line cupcake pan with liners.
- Whisk together flour, cocoa powder, baking powder, baking soda, and salt in a large bowl.
- In a separate bowl, cream together sugar, oil, and vanilla extract. Beat in eggs one at a time, then gradually add the buttermilk, mixing until combined.
- Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Do not overmix.
- Slowly pour in the boiling water and mix until the batter is smooth. The batter will be thin.
- Fill each cupcake liner about 2/3 full.
- Bake for 20-25 minutes, or until a toothpick inserted into the center comes out clean.
- Let cupcakes cool in the pan for a few minutes before transferring them to a wire rack to cool completely.
- In a large bowl, beat the softened butter until light and fluffy.
- Gradually add the sifted powdered sugar, alternating with the heavy cream, until a smooth frosting forms. Beat in vanilla extract.
- Divide the frosting into two bowls. Tint one bowl a deep, vibrant red using the gel food coloring. Add a tiny touch of black food coloring to the other bowl, just to create a shadowy, greyish hue (optional).
- Frost the cupcakes. Option 1: Use a piping bag to create red and gray swirls over each cupcake. Using a toothpick, gently swirl the colors together to create a marble effect. Option 2: If using a piping bag, fill with white frosting and frost the cupcake. Gently dab a thin layer of red and grey frosting over the white frosting, and use a toothpick to swirl.
- Chill the frosted Blood Moon Cupcakes Striking Halloween for about 15 minutes to allow the frosting to set (optional).
