Unicorn Bath Bombs

Here at Ruffles and Rain Boots, we definitely have a thing for unicorns. I mean, if you think about it, unicorns, mermaids and dragons are kind of the most fun you can have. Sure, all those other mythical creatures are cool, but those three? Tops. So, when the kiddo asked for some new bath bombs, I figured it was time to try out the method I’d planned a while ago to make unicorn bath bombs–with sprinkles!


The trick is to use sprinkles coordinated with colors for the stripes. I mean, that is just kind of everything, honestly. You get more enjoyment than you can imagine for that. So, if you’re ready to make a magically fun DIY bath bomb, let’s get started.

Tips to Make Unicorn Sprinkle Bath Bombs

  • Start by grabbing the insanely cute unicorn sprinkles here. They make these fun unicorn sprinkle bath bombs, well, all sprinkley. They’re worth it.
  • To get a really bright gold in running through the midline of your bath bombs using gold edible glitter, either make the mixture super thick or plan on painting a couple of coats. The bath bomb mixture kind of soaks it up if you make the mixture too thin. If you want to use the same gold edible glitter as me, grab it here.
  • Plan on having your bath bombs dry for about 24 hours before you use them to amp up the fizz. Plus, by letting the bath bombs dry for that long, if you’ve added a bit much liquid to the mixture, you’ll still be able to get peak fizz.
  • I always recommend that you keep your Lush-inspired bath bombs in an air-tight container like a mason jar, Tupperware or seal-top plastic baggie, so that they last longer with the most fizz. And keep in mind, if you plan on giving them as a gift, you should keep them in an airtight container and maybe tell your recipient too.
  • Remember that you can put as much or as little fragrance or color into your unicorn bath bombs as you want-–they’re your bath bombs and it’s your bath. But never (and I mean never) use food coloring. If you do, you’ll color the bathtub and quite possibly your skin. So, even though it’s a little less convenient to find soap colorant or mica powders–it’s worth it in the long run.
  • These unicorn sprinkles bath bombs are essentially just made-up of essential oils, citric acid, and a bit of water (and some other stuff but that’s basically it), just like all of my bath bombs. So, if you run into any trouble getting your bath bombs to hold their shape, they’re probably not wet enough–the recipe is intended to be a bit dry. Just add a little spritz of water and try again.

  1. Combine the baking soda, citric acid, cornstarch and epsom salts. 
  2. In another bowl, stir together the melted coconut oil and witch hazel. 
  3. Add the wet ingredients, about 1 tsp at a time, to the dry ingredients, stirring slowly so as not to kick up the fizzing. 
  4. Split out about 1/2 cup of the bath bomb mixture into two separate small bowls.
  5. In one of the smaller bowl, add the pink mica powder colorant and stir to combine, then repeat with the blue mica powder in the other small bowl.
  6. Dust the inside of one half of a bath bomb mold with cornstarch. Because the side of the bath bomb with the sprinkle tends to just come out on its own, so I don't feel the need to dust that side with cornstarch.
  7. In the non-cornstarch-dusted side of the bath bomb mold, place about 1 tsp of the unicorn sprinkles. 
  8. Pack the sprinkles-side of the mold full of the white bath bomb mixture to just about 2/3 full. Then add about a tsp of pink bath bomb mixture spread from side to side, then add about a tsp of white mixture to top off the mold.
  9. In cornstarch-dusted bath bomb mold, pack it about 2/3 full of the white mixture, followed by a tsp portion of blue bath bomb mixture spread from side to side, then topped with an additional tsp of white mixture to top it off. 
  10. Pack a little bit of extra white bath bomb mixture between the two molds, pressing and grinding the two sides together to force the two sides to combine.
  11. To release the bath bomb from the mold, allow the bath bombs to rest in the mold for up to 24 hours, then gently tap the sides of the mold and the bath bombs will pop right out.
  12. To add the gold stripe to the middle of the bath bombs, combine about 1 tsp of edible gold glitter and alcohol in a small bowl, then paint a stripe of the glitter mixture to the middle of each bath bomb.
  13. Use your bath bombs immediately or store in an airtight container until you’re ready to use!
