Super Simple Bloody Knife Halloween Cupcakes

These bloody knife Halloween cupcakes are super simple to make and would be a great scary dessert for your Halloween party or murder mystery dinner.

If you’re like me, you see all kinds of beautiful Halloween cupcakes on Pinterest and know that you have no chance of successfully making any of them. Which is why I like to come up with really easy alternatives (like my graveyard Halloween cupcakes and these devilish cupcakes) that still look good but are perfect for those of us who aren’t great bakers.

These bloody knife Halloween cupcakes would be perfect for a slaughter house Halloween party or a murder mystery dinner…or if you just want some spooky cupcakes in the Halloween spirit.

As usual with decorated cupcakes, these are my really easy take-off of a much fancier dessert that I found on Pinterest. With my limited baking skills, I always have to make the cupcake decorations as easy as possible!

Having said that, here’s the original inspiration for these cupcakes…this awesome cake from

I knew there was no way I was going to get red icing that would look like blood dripping down the side of the cake and actually stay like that. But I love the idea of this cake for Halloween, so I came up with my super simple version.

As always, I prefer cupcakes for my parties…they’re just easier to serve.

How To Make Bloody Knife Halloween Cupcakes

Part of the appeal of this cake is that the inside is red, too. So I made the cupcakes using my favoriteĀ red velvet cake recipe, but you could also use a store bought red velvet cake mix if you prefer.

Then I mixed up some cream cheese icing to go with it. You can use the store-bought kind if you want, but this recipe is really easy and tastes great so I actually prefer to make it myself.

To get the icing piled high on the cupcake, I made my homemade version of a piping bag using a ziploc bag. To do this:

  • cut off one of the bottom corners of the ziploc bag
  • fill it up with icing and zip the bag closed
  • squeeze the icing out through the hole while moving your hand in a circular motion over the cupcake. I find that starting on the outside edge and moving in works the best.

Of course, if you have a proper piping bag, that works, too šŸ™‚

To get the “blood”, drizzle a little bit of strawberry or raspberry sundae sauce over the top. Be careful not to pour too much on or it will drown the cupcake.

Finally, stick a candy knife* in the top of the cupcake and you’re done! See, that wasn’t hard at all!
