Step 2: Repeat the steps above for the Shea butter.

Steps 3-5: Mix in essential oils, Argan oil and glycerin.

Steps 6-7: Fold in half of the cornstarch and add the whipped soap base. Mix on low with a hand or stand mixer for 1 minute. Mix on high until mixture begins to thicken and is light and fluffy, much like frosting.

Steps 8-9: Add in the mica powder and beat for 1 more minute. If the mixture is not beginning to form stiff peaks like a meringue, add more cornstarch, 1 teaspoon at a time until it does.

Steps 10-12: Divide whipped soap into 3 small mixing bowls and add pink color to one bowl, yellow to another and teal to the last bowl. Start with 1-2 drops of color and mix it in. If you want a darker color, add 1-2 more drops and repeat until you get the color you want.

Step 13-14b: Add one of each color frosting to each of the 3 piping bags. Hold bags together so all sides of the tips meet. Add frosting tip and the coupler.

Step 15: Holding all three bags tightly in your dominant hand and pipe the frosting into your Mason Jar. Top with sprinkles if desired.
