Found this recipe and just had to share since it's so close to Halloween.
Plus it's so easy:
Here's how:
1) Bake cupcakes using your favorite recipe.
2) Once cooled, dig a small lump of cupcake out of the top. Set the removed chunk aside.
3) Pour a little bit of an edible, reddish, runny substance, such as strawberry jam or cherry pie filling, into the hole.
4) Re-insert removed chunk.
5) Frost the top (thereby covering up the evidence of step 2).
6) Dip a toothpick into some of the leftover jam (filling, sauce, red icing, etc.) and stab the top of the cupcake twice to give the appearance of fang marks.
Put these cupcakes out on your Halloween snack table and you will be crowned the buffet vampire slayer.
