Soap Dough – Soap You Can Play With!

Soap Dough – a super easy soap recipe that you can play with like play dough and wash yourself with!

DIY Soap Dough!! Playdough you can bathe with!!

My little boy is obsessed with play dough & slime. He loves the texture & playing with it.

Recently, we began making soap dough for his baths and we are in love. Even my 16 year old daughter is loving this and likes her own personal batch for her bath time.

It’s super easy to make.  All you need is castile soap, cornstarch, food dye, water, & optionally you can add essential oils. You can make just one color, or you can make a couple different colors to layer together like we did. We chose to dye ours with blue, purple, & pink. Kinda gave it a unicorn flare, don’t ya think? 🙂

It only takes a tiny bit to lather up into suds.  It dissolves completely in the tub.

My 16 year old swears by it as a bath bomb!

We keep ours in an airtight container & pinch some off when we want to use it.

Soap Dough

  • 1/4 cup castile soap
  • 1/4 cup water
  • 1 cup cornstarch
  • food dye
  • essential oil of your choice (optional)


  • Whisk together the castile soap & water. Mix in enough food dye to make the color you want. Add essential oils now if you wish. I really like lavender. Stir in the cornstarch. You may want to use your hands at this point for easier mixing! It shouldn't be wet or sticky once mixed - if it feels that way add a couple more tablespoons of cornstarch.
  • Keep in an airtight container. Pinch of some when you want to use it.
  • I made 3 batches - dyed one pink one blue, & one purple. Then I stacked them on top of each other, pressed down, and folded. I did this a couple of times to make several layers in the soap dough.
