Baking Soda Sea Art - Quick and Easy Baking Soda dough recipe and starfish tutorial

I was planning on decorating for July 4th, but decided to skip it and do my summer décor instead. It actually worked out really well since I was able to do a fun craft with my girls and also make some fun baking soda dough sea art. Baking soda sea art? Yes, you heard me right…baking soda.

You’ve heard of salt dough right? Well, baking soda dough is sooooo much better because it’s so easy to make, easy to handle, and holds up well! I hadn’t even heard of baking soda dough before Pinterest and I’m so happy that someone out there was smart enough to make it. Now, I don’t know where this recipe originated from since I found a gazillon recipes on the web for this, but I first learned about baking soda dough from a pin linked to Urban Bliss Life (smaller batch recipe).

Baking Soda Sea Art – Starfish


  • Baking soda dough (recipe below)
  • Silpat mat or parchment paper
  • cookie cutters
  • round tip needle
  • paint brushes
  • white acrylic paint
  • tropical blue paint or paint color of your choice
  • thick art paper to fit inside picture frame
  • silver nail polish
  • clear acrylic spray
  • E6000 glue
  • newspaper or something to cover your table surface

Cooking doug

1. Cook baking soda, cornstarch, and water in a pot over medium heat. Continuously stir until it thickens to a mash potato consistency and starts to come together.

2. Dump out dough onto parchment paper or Silpat and cover with a damp cloth until it is cool enough to handle. *Keep a damp cloth on unused dough to keep it moist while sculpting*

Roll out dough

3. Roll out dough into 1/4″ thick sheet and use cookie cutters to cut shapes or free hand design your shapes.

Shaping dough

4. To make the starfish, take the 5 balls and use your thumb and pointer finger to shape and flatten into triangles. Take the triangles and combine them together, pinching the edges on both the front and back into the shape of a starfish. *Very important to smooth out the edges where the pieces connect or you will get seams and lots of cracks* The circles were used to make sand dollars.

5. Start to decorate your starfish. I used the round end of a pin and the end of my paint brushes to make decorations on my starfish.

Sea Shapes

6. Sand dollars were made using a circle cutter and decorated using the pin head and a butter knife. The coral was made free hand.

Paint Starfish

7. Bake at 175F degrees on Silpat mat or parchment paper for 45 minutes to 1 hour. Let cool. *Dough can be air dried for 2-4 days.*

8. While the shapes are cooling, place newspaper or some type of covering on your table surface to protect it from the paint. Then, get creative and start painting! *I painted my starfish white and used my silver nail polish to highlight.* Let paint dry and seal with a clear acrylic spray. You can stop here and use the shapes as is or continue on to make a picture background.

Mount Starfish

9. Since I wanted to mount my starfish on a sea colored background in my shadow box frame, I painted an ombre blue background. Do this by starting with the darkest color on the bottom and gradually add white paint till you get to the top. *I tried to separate my paper into three sections and concentrated on three shades of blue.*

10. Once dry, glue the starfish on the background. Place in frame.

There you have it. A quick and easy project that is fun to do with the kids and can make beautiful summer decor for the home.

What will you make with baking soda dough?


Baking Soda Dough


  • 2 cups baking soda
  • 1 cup cornstarch
  • 1 1/4 cup water


Step 1
Combine all the ingredients in a pot and heat on medium heat.
Step 2
Continue to constantly stir the ingredients until the mixture begins to thicken. It will take several minutes to thicken.
Step 3
When the mixture starts to come together and looks like mash potatoes, scoop it out onto a Silpat mat or parchment paper to cool down. Cover it with a damp cloth.
Step 4
Once the dough is cool enough to handle, you can roll it out to approximately 1/4" thickness and use cookie cutters, stamps, shape by hand, or whatever method you want to use to decorate your cut-outs.
Step 5
Bake at 175F for 45 minutes to an hour. Baking will make the ornaments turn a slightly tan color. *If you don't plan on painting the ornaments and want to keep them white, air dry for 2-4 days.*
Step 6
Let the dough cool and you're ready to decorate.

  10. Can you store any unused portions of the dough?

    • I haven’t tried to store unused portions of dough, but I don’t see why you couldn’t. I would try storing it in a ziplock bag and wrapped in a wet paper towel + saran wrap. So long as the dough remains damp (you can spritz with more water) and you don’t store for longer than a few days it could work. If you try it, I would love to know how it worked out for you.

  11. Is there a smell after these dry? Looking for a project to share with my 5 y/o that I can add essential calming oils to for him, kind of like a pendent necklace.

  12. Lee Ravenscroft says:

    Thank you for sharing you beautiful and inspiring works of art. I am going to attempt some right now for beach wedding decor.

  13. What a great, low-cost, cool idea for gifts, home decor, or even just a fun project with the kids! I was recently pricing similar coastal decor and couldn’t believe how expensive, so this is the perfect alternative. So glad to have found your blog and tutorial via Pinterest. Thanks so much for sharing!

  14. Hi. I am going to make this for a craft for my daughters beach themed party. How many does this recie make? Thanks!

    • It makes quite a bit of dough. I would say it’s enough to make at least 20 ornaments of average size. Also, if the kids are free-hand making the shapes, it would be best to try to keep it as thin as possible to cut down the bake time. If the dough starts to crack while shaping, just spray a fine mist of water or dip fingers in water to smooth over. Also, there may be small cracks after the ornaments have baked, but these can be painted over.

  15. My daughter loved it, but either I cooked too long or didn’t fully work for me. Couldn’t roll it out. Was able to mold, but it was very crumbly.
    I’ll try again another time…

  16. Thanks for sharing we had a lot of fun with this and shared your link on my blog ~ Our Nontraditional family

  17. I tried this a few weeks ago with my godchildren – using cookie cutters- and we had a lot of breakage and cracking. What did we do wrong?

    • It might be that it was rolled out too thin or baked too long. My pieces are fairly thick and I do have some cracks at times too. Sometimes it also depends on the oven. If the pieces are browning, turn your oven temperature down. These can also air dry for several days, depending on humidity.

  18. […] week I am featuring My Pinterventures who shared Baking Soda Dough Art. Such a clever way to make dough and I love the beach themed pieces she made with it. Congrats My […]

  19. What a great idea! I love anything that has to do with the beach. I’ve heard of making Christmas ornaments with baking soda dough, but never these. I can’t wait to try them. Thanks for linking up to the #throwbackThursday Link up!

  20. I need to try the baking soda dough again. I tried it a couple years ago and it didn’t turn out very well for me. I love what you created!

    hi from #ThrowbackThursday
    emma recently posted…November Thankfulness Challenge: Week 1My Profile

  21. I love this idea. Thanks for sharing with #throwbackthursdaylinkup!

  22. Just one thing I’d like to say, my art teacher always said to add the colour to the white paint, not the other way around as you have said in this article. The reason for this is that it takes so much more white paint to add to the colour, than if you add the colour to the white paint. I don’t know about you, but I can’t afford to waste my expensive art stuff.

  23. What a fantastic idea, perfect for when we do our beach/summer theme at preschool! Question, can this dough be made the night before and used the next day?

    • I don’t know if you can make it the night before since I’ve always used it right away. The dough does dry out quickly if you don’t leave a damp cloth over the unused portion. Maybe you could place it in an air tight container with a damp cloth over it to keep it from drying out. If you try it, let me know how it works.

  24. Cynthia Howe says:

    My aunt had this recipe back in the 60’s, she would make it up, and my cousins and I would make play food with it. A drop or two of food coloring added to a small amount of dough worked well. We made bacon, eggs, peas, etc. This recipe doesn’t crack like the salt dough does.

  25. Love this. Does anyone know how they will hold up over time? Will they last forever? If anyone knows, please e-mail me.

  26. This looks amazing and relatively simple to do. Will be pinning to do in the future. Thanks!

  27. I’ve never heard of baking soda dough! What a great idea! I love your idea of putting it in a shadow box too! Thanks for sharing!

  63. Oh, this is Argo/Kingsford Play Clay! I never thought of leaving it white and make sea shells with it. Very pretty.

  64. You know I remember years ago we used this dough in Girl Scouts. I loved the way it feels so soft when it’s cured. Thanks for the recipe! :-)

  65. This is so smart! They probably feel a lot like the real-life ones too with that bit of grittiness. Pinned!

  66. It always crack me up, Erlene, that I end up here through a linky, even when I don’t realize I am picking Pinterventures!! Ha. We must have some similar tastes because it has happened more than once! This looks like a lot of fun. I have never made baking soda dough, so a new adventure is in store for me! Have a wonderful day!
