To use the buttermilk powder in soap, I simply add it to my melted oils and stickblend to get rid of any clumps. If you want more milk soap recipes, check out Goat Milk Soapmaking.

Safety: Gear up in your goggles and gloves to make soap.
Step 1: Create a lye solution. Weigh the water and lye into two separate containers. Slowly pour the sodium hydroxide into the water while stirring. Stir until completely dissolved and set aside to cool.
Step 2: Prepare the base oils. First, weigh any solid oils and butters into a container and melt. You can melt using the microwave or low heat on a burner. Next, weigh each liquid oil (if any) into the melted oils.
Step 3: Prepare your molds if needed. I used a 12″ Tall & Skinny Silicone Loaf mold from Bramble Berry.
Step 4: Check the temperatures. You should now have a container containing liquid base oils and a container containing lye solution. Take the temperatures using an infra-red temperature gun. Be sure to stir each mixture before taking the temp. You want your temperatures to be between 80-100 degrees F.
Step 5: Weigh your essential oils into a glass or stainless steel container and add to your prepared base oils.
Step 6: Add your buttermilk powder to prepared oils and mix to get rid of any clumps.
Step 7: Pour your lye solution into prepared base oils and mix to light trace.
Step 8: Divide your traced soap into two containers.
Step 9: Add pumpkin seed powder and yellow clay to one and rhassoul clay to the other.
Step 10: Using your stick blender, bring each base to thick trace. If your soap isn’t thick, each layer won’t support the next. Your soap will just swirl together.
Step 11: Glop half of your first base into your mold and flatten.
Step 12: Dust with charcoal powder. I use a small tea strainer to dust the charcoal on. Don’t overdo it! If you use too much, creating a solid line, your soap might come apart. You want to still see some of your bottom layer through the charcoal dusting.
Step 13: Plop on your next layer and flatten as best you can. Dust another charcoal line.
Step 14: Repeat twice more. You should have two layers from each color.
Step 15: To add texture, I used a fork and scraped it across the top of the soap as shown.
Step 16: Allow your soap to saponify and harden for 24 hours. Unmold and cut!
Step 17: Cure for a minimum of 4-6 weeks.
