This original project was made by Soapy Love a long while ago, but credit is still due!  This has now been reproduced here in full in case the original text goes offline.


What you’ll need:

3 lbs. White Melt & Pour Soap Base
Hydrated Chrome Green Oxide
Pink Ultramarine
Hello Sweet Thang fragrance oil
Jojoba Beads in Red, Purple, and Blue (we no longer stock these)
Loaf Mold
Small mixing cup
Metal 1/2 t. measuring spoon or small melon baller
Optional: Vanilla Color Stabilizer

In a small cup, combine 1/4 teaspoon of each color Jojoba Beads. Set aside.

In a 2 cup Pyrex, melt 12 ounces of white soap base. Using a small cup, spray a few squirts of rubbing alcohol and stir in 1/8 teaspoon pink oxide. Stir until all lumps are gone and add to the soap base. Add 1/2 teaspoon of fragrance oil and pour into soap mold. If you are using Vanilla Color Stabilizer to decrease the natural browning effect of the Vanilla in the fragrance, combine it with the fragrance every time fragrance is called for at a 1:1 ratio. Allow to set until surface is solid but still warm and you can push a dent into the soap with your finger.

Take your teaspoon and scoop 3 long grooves out of the soap, like you’re scooping ice cream. Make them about 1/4″ deep, then use your finger to round off any hard edges (you want smooth curves when you slice into the soap).

Melt 8 ounces of white soap. Let cool to 120 degrees. Spray surface of pink soap with rubbing alcohol and pour soap into mold. When soap is set but scoopable, make 3 more grooves like you did in the last step.

Melt 12 ounces of white soap. Dilute 1/8 teaspoon of hydrated green oxide in a few sprays of rubbing alcohol and add to soap. Stir in 1/2 teaspoon of fragrance oil. Let cool to 120 degrees, spray white soap layer with alcohol, and pour green soap into mold. Let cool until solid.

Melt 10 ounces of white soap. Let cool to 120 degrees and stir in 1/8 teaspoon of Jojoba Beads. Stir until soap is thick and beads stop floating. Spray green soap with alcohol and pour soap into mold.

To create a frosting effect, use a spoon to push melted soap back and forth. Keep pushing as it starts solidifying, creating a frosting texture. Push and push until you like the texture or it’s too thick to move anymore. Sprinkle more Jojoba Beads on top.

Let soap completely solidify. You can let it sit overnight or put in the freezer for 20 minutes. Unmold and slice with an unserrated knife.

These soaps would make excellent favors for your next birthday party!
