Ingredients for Halloween Bubble Bars
Dry Ingredients
- 1 cup baking soda
- 1/2 cup cream of tartar
- 1/2 cup cornstarch
- 1/4 cup SLSA (Sodium Lauryl Sulfoacetate – a gentle bubbling agent)
Wet Ingredients
- 2 tbsp vegetable glycerin
- 2 tbsp melted coconut oil or shea butter
- 1 tsp polysorbate 80 (optional, but helps with color dispersion and reduces tub mess)
- Orange and black mica or soap-safe colorants
- Fall-inspired fragrance or essential oils
- Wax paper or parchment for rolling
Step-by-Step Instructions
1. Mix Your Base
In a large bowl, combine the baking soda, cream of tartar, cornstarch, and SLSA. Stir gently to avoid creating a powder cloud.
2. Add Oils & Fragrance
In a smaller bowl, mix your melted coconut oil, glycerin, fragrance, and polysorbate 80. Slowly add this to your dry ingredients and stir until it forms a soft, moldable dough.
3. Divide and Colour
Split your dough into two equal parts. Add black colorant to one and orange to the other. Knead gently (wear gloves if you’d like to avoid spooky fingers).
4. Roll, Stack, and Swirl
On a piece of parchment paper, flatten each color into a rectangle. Stack them, then roll into a log—just like making a Halloween pinwheel cookie.
5. Slice Into Bars
Slice your log into thick, circular bars. Each one will have a haunting swirl that looks as good as it smells.
6. Let Them Dry
Place bars on parchment and let them air-dry for 48–72 hours. They’ll harden naturally and be ready for gift wrapping or your next bath.
How to Use
Crumble a piece of bubble bar under warm, running water. The more movement and water pressure, the more bubbles! For even fluffier results, crumble the bar in a mesh strainer under the tap.

I made a double batch of these last October and slipped them into the kids’ treat bags for their friends. They were a hit! One mum even texted asking where I bought them. That’s when you know you’ve nailed it.
