DIY Donut Bath Bombs

Handmade donut bath bombs topped with icing and sprinkles
Author Crystal


  • 1 cup baking soda
  • ½ cup citric acid
  • ½ cup corn starch
  • 3 tbsp Epsom salt
  • 3 tsp coconut oil melted
  • Small spray bottle of Witch Hazel
  • 15 drops of essential oil
  • pink cosmetic grade pigment
  • sprinkles
  • 1/2 lb goat's milk soap base melted


  • In a large bowl combine baking soda, citric acid, cornstarch, epsom salt and pigment.
  • Pour in melted coconut oil and essential oil. Mix until well combined.
  • Lightly spray witch hazel a few times until you can gather the mix in your fist and it holds its shape. If it easily falls apart then you might need 1-3 more sprays of witch hazel. Avoid spraying too much or your mix will start fizzing. You only need enough to slightly dampen the mix.
  • Press the mix into your mold and allow them to set for a few hours or overnight, before removing.
  • Melt soap and dip the top of the donut bath bombs twice. Immediately add sprinkles. Let soap set for 10 minutes.
