If you’re a fan of bath bombs or really cool looking, fun items then you are going to love what I have for you today. My favourite bath bomb recipe in the world. That’s right – we’re making quick and easy donut bath bombs!

Bath bombs are a favourite home recipe in our house. We started making them because my daughter and her friends think they are cool, but we keep making them because my 5 year old son both loves making them and loves enjoying them in the bath.

We were ready to spice things up a bit though and make something more interesting than the usual round bath bomb. That’s when I came across some pictures of donut bath bombs and loved the idea. However, I still wasn’t convinced as they seemed hard to make and I like things simple and easy.

Then I came across the idea of using melt and pour soap and sprinkles for the top part and it sounded so easy that I couldn’t wait to make them.

They were a fun success… At least, once I convinced my 5 year old he couldn’t eat them 😂 

Now, we make them regularly and I can’t recommend them enough.

Below, I share everything you need to know to become a donut bath bomb making expert from why I recommend you make them to what ingredients you need and why (including where to buy them in Australia) and detailed instructions for exactly how to make your own donut bath bombs. Give it a go!

Why Make Donut Shaped Bath Bombs?

There are many reasons we like making donut bath bombs and you might too.

They Look Amazing!

Tell me a donut bath bomb doesn’t look cool! They definitely look more interesting than the regular round type and make more of a splash when you show them to others.

They Make Awesome Gifts

Bath bombs make a great gift for anyone who likes baths. Add in the novelty of a donut shaped one and you can’t go wrong 🙂 We love giving them away.

To Stop Putting Harmful Chemicals In The Bath

The amount of chemicals in store bought bath bombs can be crazy. By making them yourself, you know exactly what is in it and you can ensure you are happy with every single ingredient.

They Are Easy And Fun To Make

Second only to how cool they look, I love how easy they are to make. It really doesn’t take long at all and you get something that looks like you put a lot of effort in. Winning!

My 5 year old is the biggest fan of this item and helps me make them. I just add the wet ingredients for him while he mixes and I dip them in the melted soap while he adds the sprinkles. This way it’s completely safe and works out to be a great activity for the two of us.

Ingredients You Need For A Donut Bath Bomb

The good news about making bath bombs is that most ingredients are available at your local supermarket. The following is what you need to not just make a great, beneficial bath bomb but to also decorate it so it looks like a delicious donut.

Bicarbonate Of Soda

Also known as bicarb or baking soda, this ingredient is an alkaline which has anti-inflammatory properties. It also helps detoxify the skin.

Some ingredients are available at the supermarket like the bicarb, citric acid and epsom salts that I am mixing together here

Citric Acid

Citric acid is a key ingredient as its reaction with bicarbonate of soda and the water in the bath is what makes the fizz when the bath bomb goes in the bath.

This means if you want more fizz, add more citric acid to the recipe below. If you want less fizz, like for kids who might be scared by it, add less.

If you don’t want to use citric acid, I have an alternative here.

Epsom Salts

In water, Epsom salts (magnesium sulfate) breaks down into its magnesium and sulfate components. It’s popular for use in baths by itself thanks to its reputation for relaxing muscles, soothing skin and loosening joints.

Coconut Oil

Coconut oil is a popular ingredient in skincare which can cleanse, moisturise and soften. It also has antibacterial and antifungal properties. It works great in bath bombs to help the bath water feel “softer”.

Essential Oils

You don’t have to add essential oils to your bath bombs, but they do make it extra nice! They don’t just help your bath smell good but can add some extra benefits as well depending on the oil you choose.

I always use essential oils in my bath bombs for a better bath experience.

You can choose which oils you add and how much depending on your preferences. The amount in the recipe is simply a starting point that works for our household.

Note also that essential oils aren’t recommended for all people and you need to make a decision for yourself and your family which oils are safe and how much.

You can use just one oil or you can combine multiple oils to make a blend. Here’s some I enjoy:

  • Lavender – This is my favourite. I just love the smell. It’s also known for being relaxing and helping little ones sleep. It softens skin and battles anxiety.
  • Peppermint – Is another favourite but it is a stronger smell so isn’t for everyone. It is known for being energising and focusing the mind. It’s also a good choice if you have a cold.
  • Eucalyptus – This is another one with a strong smell which is great for colds. It’s not recommended for people who prefer more subtle smells.
  • Lemon – Is also a winning oil for colds as well as attention and focus. It promotes positive energy.
  • Orange – Is another uplifting essential oil, good for positivity and immune systems.
  • Ylang Ylang – This oil is great for stress and anxiety as it can act as an anti-depressant.
  • Chamomile – Is a good choice if you want something soothing and relaxing.
  • Rosemary – This is a popular choice for relieving stress, promoting memory and dealing with muscle soreness.

Adding colour to your donut bath bomb is completely option but it does make it look cooler!

Not adding colouring can be a good move to keep the recipe simple or to make sure you aren’t using anything that isn’t all natural, but there are some good natural ingredients you can add to give your donut bath bombs a subtle, yet great colour. This is what we do.

beet root powder

If you want a bright coloured bath bomb, you are going to struggle to find something completely natural to do this. I stick to natural ingredients which is why you won’t see any bright colours here.

If you want a bright colour, mica powder is the least problematic option in my opinion. While it is ground from stone so starts out natural, the bright coloured dyes that are added to it to create the bright colours usually aren’t.

You can buy mica powder here.

When looking for natural ingredients, you want something that only consists of one ingredients. Some recommended products to use are:

  • Brazilian clay – There are many colours of this clay which works great in bath bombs. You can pick from purple (pictured here), yellow, pink, yellow, green and red. Clay does suck up some of the moisture in the recipe so you may find you need to add more water after adding it.
  • Moroccan red clay – This clay is the one to use for red.
  • Beet root powder – I use this for a nice pink colour like pictured in this recipe.
  • Turmeric – This works for a yellow colour.
  • Ground spinach – Use this for green.
  • Cacao powder – This works for a brown colour
  • Orange peel powder – Use this for orange.

You don’t need to use much colouring – a small pinch can work well. Add a small amount to start with and then you can add more if you want more colour.

I do find the clays can be a bit drying so you may need to add a little more water after adding them.

Melt And Pour Soap Base

Our luscious shea butter melt and pour base

Melt and pour soap base is pre-made soap that you can melt and then use to make your own soap. You can also melt and use it as decoration on your DIY donut bath bomb!

It’s very easy to use as it melts easily and sets quickly. Actually, the main thing you’ll want to watch when using this ingredient is that you have everything set to go before your melt it so you can dip your donuts in before it sets.

Melt and pour soap generally contains oils, glycerin, sodium hydroxide (lye) and water. Some also have extra ingredients that you can choose like shea butter, cocoa butter and goats’ milk.

It doesn’t matter which type you buy except it should be a white colour rather than clear so it looks better on the donut. So just don’t buy the clear type.

This ingredient can add extra lather into your bath when the bath bomb is added.

Bath Bomb Sprinkles

Finally, you need some sprinkles to complete your bath bomb. I like using bath bomb sprinkles which you can get here.

You could also use glitter on top (preferably biodegradable glitter).


donut mould

There is one final item which is essential to make your donut bath bombs and that’s a donut mould!

I recommend a silicone one which is easy to buy here.

Where To Buy These Ingredients In Australia

Thankfully, it’s easy to buy there ingredients in Australia. You can get the first few at your local supermarket and the latter are easily bought online.

I use eBay and Amazon Australia to buy most my ingredients and I link to the best choice above when I talk about the ingredients.

An exception is the bath sparkles which I buy at a specialist online soap store.

How To Make Donut Bath Bombs

There are two parts to making your donut bath bomb – making the bath bomb then adding the “topping”.

You need to let your bath bomb completely dry and harden in between these stages which will take at least a few hours, ideally overnight.

So when you are ready to start making your bath bombs, you don’t need to get the melt and pour soap and sprinkles ready just yet.

The only part of this recipe which is a little tricky is when making the bath bomb to remember to add the wet ingredients to the dry SLOWLY. If you add them fast, it’ll fizzle and ruin your fizz for the bath tub.

You also need to have your sprinkles set to go when you dip your “donuts” into the melted soap as it does set quick.

DIY Donut Bath Bomb Recipe

Yield: 5
Prep Time: 15 minutes
Total Time: 15 minutes

Create awesome, fun donut bath bombs with this quick and easy recipe


  1. In one bowl, add the baking soda, citric acid and Epsom salts.
  2. Mix until well combined.
  3. In the second bowl, melt the coconut oil in the microwave and then add the essential oils. Mix.
  4. Add the melted coconut oil and essential oils into the dry bowl SLOWLY as you mix with your hands. It's important that this is slow or the mixture may start fizzing now.
  5. The goal is a wet sand like consistency that just holds together with no clumps. If it's still a little dry after adding all the coconut oil and essential oils (meaning it doesn't hold together yet), add a tiny amount of water, say 1/2 of a teaspoon or a small spray and mix again.
  6. Keep adding tiny amounts of water until it's the right consistency and holds together into a shape.
  7. If you want to add optional colouring, do this now. I add a pinch of beet root powder to make pink or a pinch of Brazilian purple clay (pictured here) to make purple.
  8. Put the mixture into your donut mould packing firmly by patting it down, trying to avoid air bubbles. Fill it to the brim.
  9. Let the donut bath bombs dry out for at least a few hours, preferably overnight.
  10. Remove the donut bath bombs from the mould.
  11. Get your melt and pour soap and bath bomb sprinkles ready
  12. Melt the melt and pour soap in the microwave checking every 15 seconds in a bowl wider than the donut shape
  13. Dip the top of the donut bath bombs in a couple of times
  14. Immediately sprinkle the sprinkles on top. Melt and pour soap can set quickly so do these tasks as quick as you can. You can melt it again if necessary.
  15. Let it dry for 15 minutes.
  16. It's best to store them in an airtight container.
