Bleeding cupcakes

I wanted to make some Hallween themed cupcakes that still tasted good, and this is what I came up with!

Step 1: Ingredients

To make these cupcakes, you will need ingredients for a white cake and some kind of red colored berry preserves of some kind.  I used raspberry jam.
I used a boxed french vanilla cake mix and substituted the amount of water they call for with buttermilk and added an extra egg.
