Fake Blood Recipes

What’s a Halloween costume party without blood for special effects? Fake blood is available in novelty and party supply stores but making it yourself is fun and you’ll see more realistic results. Mix up a batch before a party and keep the local vampires in good supply.

Here are some recipes for you to make your own realistic-looking fake blood. Real blood is reddish brown so you may need to alter the amounts of ingredients for the desired affect. Keep in mind, fake blood is messy and some of these recipes may leave stains, so use with caution and allow plenty of time for drying.

Homemade Fake Blood

  • 1 c. Karo Syrup
  • 1 Tbsp Water
  • 2 Tbsp Red Food Coloring
  • 1 tsp Yellow Food Coloring

Mix together in a mixing bowl and you’re done. Try adding blue or yellow for a different shade.

Chocolate Fake Blood

  • 1/2 c. Warm Water
  • 4 Tbsp Corn Syrup
  • 1 Tbsp Powdered Cocoa
  • 1 tsp Red Food Coloring

Blend the water and cocoa together and then add the rest of the ingredients. Let the concoction sit for awhile and skim the bubbles off of the top. Add a couple of drops of yellow food coloring if you’re not satisfied.

Simple Fake Blood

  • Clear Corn Syrup
  • Red Food Coloring
  • Milk – Optional

However much fake blood is how much corn syrup you’ll need. Pour it into a bowl and mix in some red food coloring. Add some blue if you like. Adding a small amount of milk will make the blood appear darker and thicker.

Realistic Recipe

  • 2/3 c. Corn Syrup
  • 1/3 c. Warm Water
  • 5 Tbsp Corn Starch
  • 4 tsp red food coloring
  • 1 Tbsp Powdered Cocoa
  • 2 drops of green or yellow food coloring

Mix the corn starch with the water in a large mixing bowl. Stir in the corn syrup. Add the food coloring slowly, checking for color.

Thanks to Andy for the following recipes:

Gravy Blood

This is fairly new and I haven’t had chance to test it properly but its looks GREAT!

  • Gravy Granules
  • Red Food Coloring
  • HOT Water

The directions are EASY, all you do is make the gravy up as you would normally but if you feel like it, you can make it a bit thicker, then add the red food coloring. It’s up to you how much you add but too much will stain as it will not have been diluted enough.

Cheap ‘N’ Easy Blood

This is good for spidering:

  • Plain Flour
  • Water
  • Red Food Coloring
  • 1 tsp. of Coffee

Boil the water on the stove, then sieve in the flour, making sure you get ALL of the lumps out. The quantity of ingredients aren’t important, it just depends on how much you want. Once you have the flour mixed nicely into the water it should look nice and thick. Next, add the red food coloring.

You will notice that it’s a ghastly, bright red colour but don’t worry this is why we add the coffee. It is important that when you add the coffee to make sure the mixture is hot, otherwise it wont dissolve, but up until adding the coffee can be done in a ordinary mixing jug or pan.

Palmolive Imitation Blood

You can also make fake blood with Palmolive dish soap, (it doesn’t matter how much you put in) it depends on how much blood you want! Add red berry powdered Kool-Aid!

I know another way to make fake blood!

Get some writing icing. Put it on your hand. Put some water on it! Then spread it all over your hand and there ya’ go!

Blood Paste Recipe

I was browsing through your site for recipes and thought you might like my fake blood paste recipe. I’m a makeup artist part time. I am sending a few photos as well. It would be a great pleasure if you used the recipe and photos for others to see.

What you will need:

  • Crimson red food colouring
  • Green food colouring
  • Egg yellow food colouring
  • Cheap transparent hair thick hair gel
  • Teaspoon
  • Small syringe
  • Small plastic container


1. Take 2 heaped teaspoons of hair gel and put it into the container.

2. Put a Teaspoon of Crimson Red food colouring into the container, and mix well with the teaspoon.

3. Use the syringe to suck up some green food colouring, and put 3 drops of green into the mixture, again, mix well.

4. Clean the syringe with warm water, and suck up some egg yellow food colouring, and add 3 drops to the mixture, mix well.

5. Finally, add an extra 4 drops of Crimson Red food colouring to get the right “realistic” blood tone you like.

This recipe is for a blood paste, which doesn’t run. What’s great about it is the fact that it doesn’t stain the skin because the hair gel has a cleansing agent in it. I have not yet tested it on clothing, but I am guessing it WILL stain material. But as far the skin, it’s wonderful compared to other expensive professional blood paste products, and looks exactly the same. For larger quantities, do measurements according to your desired amount.
