Instructions

Bath Bomb

  • Place all of the dry ingredients (baking soda, citric acid and epsom salt) into a large mixing bowl and mix them together.
  • Place the cocoa butter into a heat safe container and melt it on a double boiler. (If you prefer, this can also be melted in the microwave in 5-10 second bursts. Mix well in between each burst). Once melted, pour the cocoa butter on top of the dry ingredients.
  • Add the polysorbate 80 and Sugared Strawberry fragrance oil and mix well. I will normally start mixing with a spatula, but in the end you will have to mix this with your hands.
  • Spray the witch hazel on the mixture. Only do 1-2 sprays at a time. (You want to be sure not to add too much or it can cause fizzing). If you prefer you can use rubbing alcohol instead of witch hazel.
  • Then mix very well. We are gong for a consistency of wet sand. To test the consistency, you will want to grab a handful of the mixture and squeeze it in your hand into a ball. Then from about 5 inches above the bowl, drop it. If it stays in the ball and doesn’t break apart, you are at the right consistency. If it breaks apart, just add another spray or two and test it again.
  • Press the bath bomb mixture into your cupcake cup or silicone mold. You can change the colors as you go. It is important that you press it down into the mold to get it all to pack in there, the more you pack it in the mold the better your bath bomb will hold together.
  • Leave the bath bomb cup cakes to harden in for at least 6 hours. I like to just let mine set up overnight.

Whipped Soap Topping

  • Add the whipped soap base into a large bowl.
  • Start mixing the whipped soap base on a slow speed. It is going to be a little hard in the beginning to mix it.
  • Melt the melt and pour soap in the microwave. You want to do this in 10-15 second intervals, mixing well in between each one.
  • Pour the melted soap into the container with the whipped soap.
  • Add the fragrance oil.
  • Mix together well with the hand mixer. Occasionally use a spatula to wipe down the sides of the container to ensure that everything is mixing evenly.

Melt and Pour Embed

  • Melt clear melt and pour soap base.
  • Add mica powder to the melted soap and mix well. Sometimes the mica does not want to mix in, to get it to mix you can spray the top with a bit of rubbing alcohol to break the surface tension.
  • Pour into your silicone mold.
  • Spray the top of the embeds with rubbing alcohol.
  • Once hardened, remove from the mold.
  • Place the soap embed on the top of your cupcake and sprinkle with a little biodegradable glitter. If you do not have biodegradable glitter, you can also use edible glitter as this will melt in the bath water.
