These are a nice, pampering treat to both give and receive (great fillers to tuck into gift baskets ).
Ingredients are varied and I included a few different ideas to inspire some creativity (round balls, heart shaped, cupcakes and multi-colored examples).
There’s also a video tutorial at the bottom and another recipe.
First, here are a few tips:
- Tint them any color desired by adding drops of liquid food coloring.
- If wishing to make them multi-colored, mix in separate batches and then pack individually (in layers or swirls). If colors are mixed together before packing, you’ll liking get an odd solid color instead.
- If they fall apart or crumble too easily, they’re likely not being packed hard enough in the molds. It could also be that there’s not enough water.
- If they’re cracking, it’s likely that too much water has been added.
- Dry them overnight before moving or packing them then store in an airtight container.
With Witch Hazel : Ingredients include citric acid, baking soda, witch hazel, coloring, fragrance or EO. Use a shaped or dome mold to shape them.
Milk & Honey Hearts : Yields about 6 large ones made in the form of hearts.
Frosted Cupcakes : Made in silicone cupcake molds, also topped with a real sugar frosting.
Cubes : Packed in flexible silicone ice cube trays. Display in glass jars once the cubes are hardened.
Beach Shells : Made with bicarb, citric acid, ground kelp, EO blend and packed into shells.
Here’s a good step-by-step tutorial in video format. It’s a bit long at over 7 minutes, but it moves along quickly (includes some fun bloopers at the end)…
- These soften the skin, they are an emollient and they’re lots of fun–they start to fizz when they hit the water.
1 cup baking soda
3/4 cup citric acid (causes the fizzing)
2 TBS white kaolin clay 
1 TBS grapeseed oil
2 tsp Polysorbate 80  (or jojoba oil)
little bit of Vitamin E oil
1/4 tsp gel colorant
1/4 tsp Borax
1 tsp Fragrance oil
12 squirts of rubbing alcohol (mixed in 3 squirts at a time)
- Wear gloves when mixing.
- Mixture should be the consistency of damp sand before packing it.
- For something different, place candy hearts on the inside of the molds before packing in the mixture. Hearts will be seen on the outside of the finished product.
- Add dead sea salts to the extra powder mixture after making them (say you didn’t have enough left to fill another mold), seal in a ziploc bag and mix. Let the powder dry and then a nice fizzing bath salt is the result.

This is an interesting recipe, first cook a batch of bath cookies then add them to the tub after they’ve cooled.
The batch yields 24 which is enough for about 12 soaks (if using 2 at a time).
My hard copy looks like a photocopy of a newspaper clipping, but I’m not sure which newspaper or who the author is.
2 cups finely ground sea salt
1/2 cup baking soda
1/2 cup cornstarch
2 TBS light oil
1 tsp vitamin E oil
5 drops EO (choice)
- Preheat oven to 350°F.
- Mix all items together.
- Gently roll dough into balls (approx 1″ in diameter, about 1 tsp).
- Place each on an ungreased cookie sheet.
- Bake for 10 minutes until lightly browned.
- Remove from oven and allow to cool completely.
To Use: Drop 1 or 2 cookies into a warm tub and allow to dissolve.
Yield: 24 cookies
