Ingredients
Method
- Preheat oven to 350°F (175°C). Line a 12-cup muffin tin with paper liners.
- Cream butter and sugar until fluffy. Add eggs one at a time, then vanilla and red coloring.
- Whisk flour, cocoa, and salt. Alternate adding dry mixture and buttermilk. Mix baking soda with vinegar, fold in quickly.
- Divide batter evenly, filling 2/3 full. Bake 18-20 minutes. Cool 5 minutes in pan, then transfer to rack.
- Mix cake crumbs, condensed milk, melted butter, and food coloring for filling. Hollow centers of cupcakes and fill with mixture.
- Beat butter until creamy. Add powdered sugar gradually, then vanilla and milk. Tint with ivory/peach coloring.
- Frost cupcakes smoothly to cover filling. Chill briefly for neat surface.
- Make two puncture marks with candy fangs or gel. Drizzle red syrup to simulate blood drips.
Notes
Cool cupcakes fully before decorating to avoid melting frosting. Use gel-based coloring for vibrant results. For realistic blood drips, apply edible red gel and let gravity form natural trails.
