    The coming of fall is signaled by many things ... one of which is making a batch of my famous pumpkin pie soap. It uses real pumpkin and pumpkin pie spice and fills the house with wonderful spicy fall scents.

    To make this recipe you'll need:

    • A basic soap recipe
    • Pumpkin fragrance oil or essential oil blend
    • Pureed fresh or canned pumpkin
    • Pumpkin pie spice
    • Basic understanding of cold process soap making

    For this particular recipe, this grocery store soap recipe was sized up to make a bit over 4.5 lbs. You can use this one or any other basic soap recipe, and add the pumpkin puree and spices to it. The sugar and salt are optional. The salt allows the soap to harden quicker and the sugar helps boost the soap's lather.

    • 15.3 oz. lard
    • 15.3 oz. olive oil
    • 12.8 oz. coconut oil
    • 2.5 oz. castor oil
    • 5.1 oz. sunflower oil
    • 3 tsp. of sugar in the water before the lye
    • 1.5 tsp of salt in the water before the lye
    • 3 oz. of canned pumpkin
    • 2 tsp. of pumpkin pie spice
    • 2.2 oz of pumpkin pie fragrance oil (There are lots of variations on pumpkin fragrance—from spicy to creamy—most of them will contain some vanilla, so know that you're going to have discoloration
    • 7.2 oz. lye
    • 15 oz. of water (see note at bottom on the water calculation)

    Get all of your ingredients and equipment ready (including pre-measuring out all of your additives) and let's get started!

    Note: Normally, if I was adding a vegetable additive like the pumpkin, you would discount the water a bit to make up for the water content in it. But since "spice" fragrance oils can often cause the batch to get to trace quickly, don't discount any. The water in the pumpkin adds a bit more water to the recipe, which should give you a bit more time to work, get the spice portion mixed, and still layer it in the mold.)

    Prepare your lye solution, and set it aside to cool. (Be sure to add the sugar and salt to the water before you add the lye.)

    Add the Lye and Blend

    Once your lye solution and oils are at about 100 degrees, slowly add the lye water to the oils and blend. Only blend until the lye and oils are just barely mixed together. We don't want to take it to trace just yet.

    Leave the separated part for a minute. Going back to the main pot, add in the pumpkin. Make sure it is mixed in well. Also, add your pumpkin pie fragrance oil to the batch at this time.

    Blend Both to Trace

    Blend both portions of soap so that they are mixed very well. You should already be well at trace by now.

    Layer the Two Colors

    Starting with the "spice" portion, pour about 1/2 inch of soap into the bottom of the mold. Then pour about 1/2 of the whole "pumpkin" portion into the mold. Pour in a bit more of the "spice", and then some more of the "pumpkin". Alternate the two until you've filled the mold.

    Swirl in the Mold

    Using a wooden spoon or rubber spatula, gently swirl through the soap rotating the spoon/spatula around, up and down through the soap, and back and forth. You don't want to mix the colors all together, just swirl the dark and light colors with each other.

    Cover the mold with a bit of wax paper and let it set in a safe place.

    It is probably not necessary (with this recipe at least) to insulate the mold like you normally would. Most pumpkin fragrance oils contain at least a little cinnamon and/or clove essential oil in them, which will really get the saponification process going. This batch of soap will get HOT. Don't worry, this is normal. Also, don't worry about how dark the soap is getting. This is just part of the gel process. The soap will lighten back up as it cools.

    Cool, Cut, and Enjoy!

    Let the soap cool and cure overnight before slicing it.

    Though you're going to want to try it right away, let it set at least a few days before you test it, and at least a few weeks before you use it in the bath.

    As it's curing, your house will be filled with the wonderful sweet spicy scents!
