Grab a big bowl and mix your flour, cocoa powder, salt, and baking soda together. Give it a good whisk until everything's fully combined.
02 -
Take your room temperature butter and sugar and beat them together with your electric mixer on medium until they're fluffy and pale.
03 -
Drop in your eggs one at a time into the butter-sugar mix, making sure each one is fully mixed in before adding the next. Then stir in your vanilla and red food coloring.
04 -
In a small bowl, mix your buttermilk with the white vinegar. Add this liquid mix bit by bit, switching back and forth with your dry ingredients until you've got a smooth batter.
05 -
Spoon your batter into paper-lined cupcake tins, filling each about two-thirds full. Pop them in your oven at 350°F for 20 to 25 minutes. They're done when a toothpick comes out clean. Let them cool completely on a wire rack.
06 -
Mix your saved cupcake crumbs with the sweetened condensed milk, melted butter, and red food coloring. Stir until you've got a smooth, thick mixture that holds together.
07 -
After your cupcakes have cooled, cut out a small hole in the middle of each one using a knife or cupcake corer. Fill each hole with your red velvet mixture right up to the top.
08 -
Whip your softened butter until it's really creamy. Slowly add in your sifted powdered sugar, then splash in some milk or cream until it's just right. Mix in the vanilla and a tiny bit of ivory or peach coloring until you get a nice pale shade.
09 -
Spread or pipe your buttercream over each cupcake. Try to get the tops nice and smooth to look like skin.
10 -
Stick two candy fangs or red gelatin spots on each cupcake to make bite marks. Drip some red syrup or gel from these marks down the sides. If you want, stick a piece of red straw in for extra effect and add more drips around your cupcakes.

Put your finished cupcakes on a black or red plate. Add extra red syrup for a bloody look and maybe throw in some spooky props like toy bats or Halloween candles.
