Frankenstein Halloween CP Soap Design and Recipe

Ahhhh Frankenstein. Does anything represent monsters and Halloween better? Interesting fact. Did you know that the monster created by Victor Frankenstein in Shelley’s novel was nameless? Over the years, the monster has been called Frankenstein.

This Frankenstein inspired soap is easy to make using a cardboard raking/sculpting tool. It is perfect for Halloween lovers who are looking for a spooky + fun soap.

Frankenstein Halloween Soap

  • Coconut Oil – 12 oz.
  • Shea Butter – 2 oz.
  • Olive Oil – 10 oz.
  • Castor Oil – 2 oz.
  • Avocado Oil – 2 oz.
  • Rice Bran Oil – 4 oz.
  • Sodium Hydroxide – 4.6 oz.
  • Distilled Water – 9.2 oz.
  • Green Mica – 2 teaspoons
  • Charcoal – 1/2 teaspoon (or enough to color black)
  • Lemongrass Essential Oil – 2 oz. (or your favorite Halloween fragrance oil)

Safety Warning: This recipe is for soapmakers who have a basic knowledge of the soapmaking process and know the correct safety procedures to use when handling lye. If you are new to soapmaking, visit our free soap making guide or check out our Basic Soapmaking eBook. Be sure to wear safety goggles and gloves while soaping.

This recipe fits into a 12″ tall and skinny silicone loaf mold from Bramble Berry.

First create your raking tool. I used a piece of cardboard that I had sitting around. I cut the cardboard to fit inside of the mold and then cut triangles out to create a hairline as shown below.

Step 1 – Create your lye solution. Weigh out the water and sodium hydroxide into separate containers. In a well-ventilated area, sprinkle the sodium hydroxide into your water while stirring slowly. Stir until dissolved and set aside to cool.

Step 2 – Weigh and melt the shea butter and coconut oil.

Step 3 – Weigh and add the liquid oils to the melted oils. This helps to cool everything down.


Step 4 – Weigh the essential oil or fragrance oil into the oil mixture.

Step 5 – Bring your mixture to emulsion. Don’t take it to trace.


Step 6 – Pour out 10 oz. of soap and set aside.


Step 7 – Add green mica to soap and stick-blend to thick trace.


Step 8 – Pour into mold and bang down mold to flatten.

Step 9 – Use your rake tool to create the hairline. You might have to scoop soap out. Just set somewhere to saponify and you can roll into balls.

Step 10 – Color the soap that you set aside black using charcoal. It should still be quite liquid-y. Spoon carefully over the sculpted green soap.


Step 11 – Bang your soap mold down on surface to cause any bubbles or air pockets to rise to the top.

Step 12 – Let your soap sit overnight to saponify. Unmold, cut and cure your soap for 4 weeks!


Enjoy your Frankenstein soap!
