Products you need to make this recipe

Do you have one or more of these ingredients already? No Problem! Choose only what you need and the total price will adjust accordingly.

If you feel you have graduated from our basic Three Bubble Bar recipes, which we formulated, a good long time ago, it might be time to step up to this rolled solid Bubble Bath project.

Soap Queen previously did a video tutorial, which prompted us to update our formula, so this is "after" Anne-Marie's project (video below), using ingredients available in Australia.

Anne-Marie uses the yummy Celestial Waters, but we opted for Night Violet (Type) Fragrance and Sugar Plum Fairy (Type) Fragrance for the second batch.

This type of product can be a little tricky if you have never made bubble bars before, so we highly recommend watching Anne-Marie's video before you begin, it's really helpful! It's much easier to see exactly how to achieve these bars with the video, it's one of the best we've seen.

David's Solid Bubble Bath

Part One

Part Two 

  • 20g Coco Betaine Optional, you may or may not need a little extra moisture, use during kneading

For colours, use diluted Liquid Pigment Dispersions or water dispersible colours such as our Liquid Lakes. For Anne-Marie's colours, select Deep Seagreen and Deep Blue!  Or you can also use Mica powders to colour if you prefer

For our bars we used:

For Night Violet Fragrance Batch:

8 drops Royal Purple Liquid Pigment Dispersion - Diluted in 5ml Distilled water or Coco Betaine
4 drops Deep Seagreen Liquid Pigment Dispersion mixed with 10 drops of Yellow Liquid Pigment Dispersion - Diluted in 5ml Distilled water or Coco Betaine

For the Sugar Plum Fairy Batch *These ingredients are not listed in the trolley ingredients and will need to be added separately.

You'll also need:

  • Large mixing bowl
  • Sieve
  • 2 x 1 litre jugs or bowls
  • Disposable Gloves, a couple of sets
  • Gladbake (or similar) or freezer paper
  • Scrapers, non serrated narrow knife to slice the bars

David's Bubble Bar Recipe

Set out equipment and weigh ingredients ready to use.

Mix the part one ingredients together in one bowl and mix until combined.

Use a mask if susceptible to dust, and sieve part two ingredients together in another bowl.

David's Bubble Bar Recipe

Begin to add the liquid ingredients, slowly into the dry ingredients, mixing as you go.
Use a spatula or spoon at this stage until all ingredients are moistened.

Now it's time for hands!
Knead, and knead some more, scraping off your hands as you continue.

David's Bubble Bar Recipe

Knead until the mixture until it can be formed into a ball.

David's Bubble Bar Recipe 

Remove from bowl, and form into a ball or log.
Cut into two even pieces and place in separate jugs or bowls.


Now it's time for colour, you may want to use it all, or less - we used we mixed up.

You'll notice as the colour mixes into the white dough that the colour will even out and remain that tone.

If you feel you need a little extra moisture, you can add the Coco Betaine.  The mixture will be quite stiff and expect it still to look a little crumbly as you knead it.
Form into a ball and flatten onto a sheet of baking parchment dusting the surface with Bicarbonate of Soda. 
Place one colour of mixture on top of the other.

David's Bubble Bar Recipe 

Time to remove the gloves, or replace with fresh ones as you will most likely have mixture stuck of them!
Dust the top with bicarbonate of soda, and lay another sheet of baking parchment over that.
Now press it out into a squarish shape, one colour over the other, pushing and pressing it into place.
It should be very soft, almost marshmallow like.

David's Bubble Bar Recipe

Once it has been flattened out it is time to form the roll.
Now begin to roll, like a roulade or swiss roll, tucking the very first edge under a little to allow you to guide the roll over, using the paper to assist you.

David's Bubble Bar Recipe

This gives you the edge, and then you can continue rolling completely into a cylindrical loaf.

David's Bubble Bar Recipe

The paper will stick a little (or a lot!) but just continue to coax it into the roll, tapping the ends in to keep it a nice log shape.

Carefully remove the paper, and place on a firm surface. The loaf will be quite soft and almost "fluffy".
Slice the thin blade knife under each slice, to carefully move it just slightly so it will dry in a nice shape

Hand Made Solid Bubble Bath

Once sliced, place in a dry place for at least a week or two to dry out, then they are ready to use!
We find it's best to wrap the bars after the drying time and place in a jar for best storage or wrapped in semi-breathable food wrap (like cheese paper)


To Use: Break off a "chunk" and crumble under the running tap, your bath will have loads of bubbles, and no plastic bottle waste!

Ingredients in "Add to Trolley" are for Night Violet Batch - there will be left over ingredients for most items.  If making two batches just double check if you need to purchase 2 of anything (such as Cream of Tartar).
