Ingredients:
- 1 ½ cups All-Purpose Flour (sifted)
- ¾ cup Granulated Sugar
- ½ cup Unsweetened Cocoa Powder (high-quality dark cocoa)
- 1 tsp Baking Soda
- ½ tsp Salt
- 2 large Eggs, at room temperature
- ½ cup Buttermilk, at room temperature
- ¼ cup Neutral Vegetable Oil
- 1 tsp Vanilla Extract
- ½ cup Hot, Freshly Brewed Coffee
- 1 cup Frozen Raspberries
- ¼ cup Granulated Sugar (for filling)
- 1 tsp Lemon Juice
- 1 cup (2 sticks) Unsalted Butter, softened
- 4 cups Powdered Sugar (sifted)
- ½ tsp Salt (for buttercream)
- 2 tsp Vanilla Extract (for buttercream)
- 3-4 tbsp Milk or Cream
- Green Gel Food Colouring
- 10 Chocolate Sandwich Cookies, crushed (filling removed optional)
- 12 Small Plain Rectangular Biscuits (for tombstones)
Instructions:
- Prepare the Raspberry Filling: Combine raspberries, sugar, and lemon juice in a small saucepan over medium heat.
- Reduce: Bring to a boil, then reduce heat and simmer for 10-15 minutes, stirring occasionally, until the mixture has thickened to a jam consistency.
- Cool: Transfer the 'blood' filling to a small bowl and place it in the refrigerator to cool completely.
- Preheat and Prepare: Preheat oven to 350°F (180°C). Line the muffin tin with paper cases.
- Combine Dry Ingredients: Whisk together the sifted flour, cocoa, sugar, baking soda, and salt in a large bowl.
- Combine Wet Ingredients: In a separate medium bowl, whisk together the eggs, buttermilk, oil, and vanilla extract.
- Mix Batter: Pour the wet ingredients into the dry ingredients and mix on low speed until just combined (do not overmix!).
- Add Coffee: Carefully pour the hot coffee into the batter and mix until smooth. The batter will be thin—this is correct.
- Bake: Fill the cupcake cases about two-thirds full. Bake for 18–20 minutes, or until a skewer inserted into the centre comes out clean.
- Cool: Transfer the cakes to a wire rack immediately and allow them to cool completely before assembly.
- Cream Butter: Using an electric mixer, beat the softened butter on medium speed until very pale and fluffy (about 3-4 minutes).
- Add Sugar: Gradually add the sifted powdered sugar, one cup at a time, mixing on low speed until incorporated, then increase speed to medium-high.
- Finish Frosting: Add the salt and vanilla. Beat in the milk or cream, one tablespoon at a time, until the buttercream reaches a smooth, pipeable consistency.
- Colour: Add a few drops of green gel colouring and mix thoroughly until you achieve your desired eerie hue.
- Prep Grave Dirt: Crush the chocolate sandwich cookies until they resemble fine, dark soil.
- Core: Once the cupcakes are fully cool, use an apple corer or a small sharp knife to cut a shallow, conical hole in the centre of each cake.
- Fill: Spoon 1–2 teaspoons of the chilled raspberry 'blood' filling into each cavity.
- Frost: Fit the piping bag with a large star nozzle and pipe a generous swirl onto each cupcake.
- Decorate: Dip the frosted cupcakes lightly into the crushed chocolate ‘dirt’ so the edges of the buttercream are coated.
- Tombstones: Insert one rectangular biscuit into the top of the 'dirt' mixture on each cake to resemble a small tombstone.
