When April mentioned Amayori’s shower mochi a few weeks ago, I got really excited. They promised the luxury of a scented bath with all the efficiency of a shower. Plus, no tub ring!

A shower mochi is a little cake that dissolves in your shower, releasing clouds of fragrance. They’re named after mochi, a little round Japanese cake made from rice paste. Mochi are delicious, adorable, and a little powdery, so they’re the perfect inspiration for a product that’s basically a bath bomb for your shower.

I’d love to try Amayori’s shower mochis, but $21 US (plus shipping) for three mochi is a little steep, given that each one only lasts a few minutes before it literally runs down the drain. So I decided to DIY my own. (If you want Amayori’s beautiful packaging or signature scent, you’ll have to spring for their version!)

It turns out that people have been all over this concept for years. If you search for “homemade shower steamer,” “shower bath bomb,” or “DIY Lush Emotibomb,” you’ll find lots of tutorials. I combined a few into my own road-tested recipe.


DIY Shower CakesMakes 3 or 4Ingredients

• ½ cup baking soda

• ¼ cup citric acid (you’ll find it in the canning section of the grocery store)

• ¼ cup cornstarch

• 1-2 tablespoons water

• essential oils or fragrance oils

• something you can use as a mold—a mini cupcake pan, silicon molds for baking, or even an ice cube tray.

• optional: gloves (like hair-dyeing gloves)

1) Combine the baking soda, citric acid and cornstarch in a medium-sized bowl. Stir so they’re evenly combined. Add 20 to 40 drops of essential oil to the dry mix and stir.

I want everything in my life to smell like Atelier Orange Sanguine, so I used a sweet orange oil. I do not have a nuanced approach to scent. You can also use pre-mixed essential blends. (I wanna try this one.)

Remember: this thing is going to be in the shower with your naked body, so don’t use cinnamon or other oils that could irritate your bare skin.

2) Start adding the water a little bit at a time, mixing with your hands as you go. The mixture will start to fizz a little. Don’t be alarmed. This is just Mad Beauty Science at work.

If you have sensitive skin, you may want to wear gloves so the citric acid doesn’t sting you (I didn’t bother).

Stop adding water when you can easily shape the mixture into a ball without it crumbling.

3) Pack the mixture into a mold. I used these tiny spice bowls from IKEA because they’re close to the size and shape of a real mochi cake. You can also try to form the mixture into balls, free-style.

Don’t fill the mold to the top: the “dough” will expand by 20-30%.

4) Put the cakes in a dry, ventilated place and let them air-dry for 24 to 48 hours. Don’t put them in the oven—the heat will destroy the scent.

To use, put your cake on the floor of your shower where the water can hit it. It will slowly dissolve over the course of your shower, enveloping you in the scent of your choice.

Store extra cakes in a dry, airtight container. Moisture will mess them up, so maybe keep them outside your bathroom.

If you want to give them as gifts, wrap each one in cake or candy foil (you can get it at craft or kitchen stores). Michael's sells cute little treat boxes if you want to get extra-Martha about it.

  • Who’s excited for shower cakes?!
  • Did any of you mourn the loss of Lush’s discontinued Emotibomb discs?
  • What scents are y’all going to try? I want to make a rose one next.
