About: Hi, I’m Deidre from Our Upcycled Life! ♻️✨ I’m a DIY and upcycling creator who loves giving old, forgotten things a second life. Whether it’s a chipped teapot from the thrift store or a dresser that’s seen bet…

Today we’re making baking soda clay a super versatile, affordable clay that’s easy to mix, air dries naturally, and can be used for tons of creative projects!

This recipe only takes a few simple ingredients you probably already have at home, and it’s completely non-toxic and kid-friendly, making it perfect for crafting with little ones or grandkids.

Supplies

What You’ll Need

  1. ½ cup baking soda
  2. ¼ cup cornstarch
  3. ¼ cup water
  4. Measuring cup and fork
  5. Saucepan
  6. Non-stick sheet or parchment paper
  7. Rolling pin and cookie cutters
  8. Optional: food coloring for tinting your clay

Step 1: Combine the Ingredients

In a measuring cup, mix your baking soda, cornstarch, and water until smooth.

The ingredients come together quickly, forming a silky mixture that’s the base of your clay.

Step 2: Heat It Gently

Pour the mixture into a small saucepan and place it on low heat.

Keep stirring constantly, don’t walk away! You’ll see the texture start to change as it thickens and pulls away from the sides of the pan.

This only takes a few minutes, and it’s the key step to getting the right consistency.

Step 3: Step 3: Let It Cool

Once the mixture forms a dough-like ball, remove it from the pan and let it cool completely.

You’ll know it’s ready when it feels soft, smooth, and easy to handle.

Step 4: Add Color (Optional)

If you want colored clay, add a few drops of food coloring and knead it in until evenly blended.

You can keep it classic white, or tint it for a fun pop of color — pastel pinks, soft blues, or holiday reds and greens all look beautiful.

Step 5: Roll It Out

Place your clay on a non-stick surface or parchment paper and roll it to your desired thickness.

Use wooden slats, dowels, or any guide to keep it even.

Step 6: Cut and Shape

Grab your cookie cutters or silicone molds and start creating!

This clay holds details beautifully, so it’s perfect for intricate molds, frames, or stamped designs.

Step 7: Air Dry

Lay your pieces flat and let them air dry for a day or two.

Once dry, they’ll be lightweight, durable, and ready to paint, seal, or decorate. Use a bit of fine-grit sandpaper to smooth the edges.

You can add twine to turn them into ornaments, or leave them plain for a modern minimalist look. I show every step, share a few fun mishaps, and give you the exact recipe ratios so your clay turns out just right every time! Watch Now
