A magical blue cupcake bath bomb making project
In a large mixing bowl, add the baking soda, citric acid, Bentonite Clay, Epsom Salts and cornstarch. Mix the dry ingredients together.
In the microwave safe cup melt the coconut oil for a few seconds in the microwave until it is just liquid. Add the Polysorbate 80, scented oil and blue colorant. Mix together.
Add the wet mixture to the large bowl of dry mix. Mix everything together. You will want to use your hands and may want to use disposable gloves so you don't color your hands. Make sure you break down all the lumps and it is really well mixed. It will feel like wet sand once it is completely mixed.
Fill each cavity of the muffin mold. Press down firmly.
Let set for 24 to 48 hours.
Add whipped soap base, scented oil and glycerin to mixing bowl. Mix on low speed until fluffy, or about 1 minute.
Melt your soap base in microwave safe bowl in 30-second intervals, stirring after each until melted. Allow to cool for about a minute.
Mix in melted soap base and cornstarch and mix on high speed for 1 minute or until the mixture forms peaks, like when you make a meringue. If your frosting is not stiff enough, add a bit more cornstarch and mix in. Repeat until the mixture is nice and firm.
Divide whipped soap into 3 small mixing bowls and add pink color to one bowl, purple 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.
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.
Holding all three bags tightly, frost cupcake bombs as you would an edible cupcake. Add a few candy sprinkles for your "fairy dust".
