Calming Bath Salt Cakes

These easy-to-make bath salt cakes are one of my favourite uses for the doTERRA Peace Reassuring Blend

DoTERRA’s Peace Reassuring Blend is a proprietary essential oil blend that promotes feelings of peace, reassurance, and contentment.

This recipe combines the benefits of an Epsom salt bath with the calming benefits of essential oils (and there’s also a little bit of sensory play thrown in for good measure).

Today I’ve used a snowflake cookie cutter that I picked up from my local kitchen supply store which I have paired with some blue natural liquid food colouring.

Try doTERRA Peace Bath Salt Cakes for Calming Sensory Play

Bath salt cakes can also be used for sensory play in the bath.

The salt cakes dry hard, but they are easy to break apart with your hands. My child absolutely loves squishing these salt cakes between their fingers as they melt in the bath water. 

You can crush them and break them and watch them fall apart in the bath water – lots of fun for a sensory seeker.

The scent of the doTERRA Peace Reassuring Blend will be released as the cakes break apart, calming the senses.

What you need

  • 1 Cup Epsom Salts
  • 2 tbsp bi-carb soda (baking soda), sifted
  • 2 tsp doTERRA Fractionated Coconut Oil
  • 2 tsp water*
  • 20 drops doTERRA Peace Reassuring Blend Essential Oil
  • Natural Colouring
  • Cookie cutters
  • Tray lined with grease-proof paper or baking paper


Add Epsom salts and sifted bi-carb into a non-plastic bowl and mix well. Add wet ingredients and stir until fully incorporated.  If you have added a lot of liquid colouring then you may need to add less water.  Your mixture should be damp but not so soggy that the salt starts to dissolve.

Place a cookie cutter on your paper-lined tray and fill it with the salt mixture. Pack it down level with the rim of the cookie cutter, and then slowly and carefully lift the cookie cutter to reveal a formed salt cake.  If you shape starts to sag or melt it means your mixture is too moist. You can add more Epsom salt to the mixture to counteract this.

Set your salt cakes aside to dry overnight, and then flip them over to dry for another 12 hours.  Store them in a plastic zip-lock bag for colour and scent longevity.  To use, drop all of them into a bath, or one or two into a bucket for a relaxing foot soak.

Recipe Notes

* Do not use water from the tap in the recipe.  This can lead to mould growth. Instead use distilled, demineralized (the water you buy from the supermarket to put in your iron), or water that has been boiled and then cooled.  Alternatively rose water (also available from the supermarket) is a great idea (and will add to the beautiful scent of your bath salt cakes).

Troubleshooting Tips

Cookie cutters with simple shapes work best for this project. If your cutter has too many fine details or narrow areas, you may find it difficult to pull the cookie cutter away without breaking your bath salt cake.

If your salt cake does not remove easily from the cookie cutter, your salt mixture is too dry. Add some more water or and try again.

If your salt cake starts to sag or lose its shape after being removed from the mould, your salt mixture is too wet. Add some more salt and try again.
