This beautiful soap is super simple to make and uses an easy layering technique.

SAFETY WARNING! If you’ve never made soap before, be sure to start with our basic soap making guide. This recipe and instructions are for experienced soap makers. Be sure to gear up in your goggles and gloves before you make soap.

This recipe fits in a Bramble Berry 10″ silicone loaf mold. I halved it when I made it to fit into a smaller test mold from Bramble Berry.

Layered Mint Cold Process Soap Recipe

  • Coconut Oil – 306 grams (34%)
  • Shea Butter – 45 grams (5%)
  • Olive Oil – 360 grams (40%)
  • Avocado Oil – 54 grams (6%)
  • Rice Bran Oil – 135 grams (15%)
  • Sodium Hydroxide – 128 grams
  • Distilled Water – 256 grams
  • Peppermint Essential Oil – 15 grams
  • Spearmint Essential Oil – 10 grams
  • Dried Peppermint Leaves – 1 teaspoon
  • Caribbean Blue Mica (Bramble Berry) – 1/8-1/4 teaspoon (Just use enough to get the green color.)
  • Charcoal – 1 tablespoon (To create the charcoal line.)

Step 1: Make your lye solution. Weigh the water and lye into separate containers. Pour the lye into the water while stirring. Be sure to mix your lye solution in a well-ventilated area.

Step 2: Weigh out your solid/hard oils and melt.

Step 3: Weigh out your liquid oils and add to your melted oils. Add the essential oil blend to the base oils.

Blend to light trace.

Step 4: Divide your batter out. I used about 2/3 for the base and 1/3 for the top.

Step 5: Color your base using Caribbean blue mica. I used about 1/4 teaspoon. Add a little and then add a little more. The blue mica + yellow soap base creates a nice green. If you add too much, you’ll get blue.

Add 1/4 teaspoon ground dried mint leaves to the other portion. (If you want!)

Step 6: Using your stick blender, bring the green base to a thicker trace.

Step 7: Pour this into your mold.

Step 8: Create your charcoal line. I use a small tea strainer to dust the charcoal on. Don’t over do it! Don’t create a solid line or your soap layers will come apart.

Step 9: Pour on your top layer. If you brought the bottom layer to thick trace then it should hold the top layer well.

Pouring over a spatula will help to ensure that the soap doesn’t dive into the bottom layer.

Let your soap sit for 24 hours, unmold and cut your soap!

Cure your soap for 4 weeks!

Happy Soaping!
