I’ve posted a few bath bomb recipes here. The most popular one makes oatmeal coconut oil bath bombs, and the most recent one makes cupcake bath bombs with pink frosting. Because I had so much fun making my cupcake bath bombs that looked as good as real cupcakes, I decided to give DIY donut bath bombs a try too. These DIY donut bath bombs look good enough to eat and are so cute. Also, this recipe uses oatmeal, a nourishing ingredient that’s great for even the most sensitive skin types. Do you want to know how to make your own donut bath bombs using oatmeal? Keep reading!

Ingredients for DIY Donut Bath Bombs

includes affiliate links

1. Donut Pan or Mold – I use the Wilton Nonstick 6-Cavity Donut Pan. But any hard donut pan or mold will do. I don’t recommend using a soft silicone mold, because its flexibility makes it hard to mold bath bombs.
2. Crushed Oatmeal – 1/2 cup. I use a spice grinder to crush my rolled oats into a fine powder. But if you don’t want to crush your own oatmeal, you can use oat flour instead.
3. Baking Soda – 1 cup to make the donut bath bombs, and 1/2 cup to make the frosting. I use the Arm & Hammer brand Baking Soda, because I can find it in most supermarkets.
4. Citric Acid – 1/2 cup to make the donut bath bombs, and 1/4 cup to make the frosting. I use Alpha Chemicals Citric Acid to make all my bath bombs. You can find citric acid pretty easily online. Also, you can sometimes find the Ball brand citric acid in the canning section of a supermarket.
5. Coconut Oil – 2 tablespoons to make the donut bath bombs, and 1/3 cup to make the frosting. My favorite coconut oil is Trader Joe’s organic virgin coconut oil. If you don’t have a Trader Joe’s near you, give Viva Naturals Organic Extra Virgin Coconut Oil a try.
6. Red Mica – about 1/8 teaspoon. Cosmetic-grade red mica is a naturally colored mineral that’s often used to make cosmetics.

How to Make DIY Donut Bath Bombs, Video Tutorial

Here’s a Youtube video that I posted to show you how to make donut bath bombs.

1. To crush your own oatmeal, place 1/2 cup of rolled oats (not instant oatmeal) in a spice grinder and pulverize until you have a fine powder. While I like making my own crushed oatmeal, you don’t have to and can use 1/2 cup of oat flour instead.
2. Combine all the dry ingredients: 1/2 cup of crushed oatmeal (or oat flour), 1 cup of baking soda, and 1/2 cup citric acid. I like to use a whisk for this step because it mixes the ingredients well and breaks up any clumps.
3. Slowly add 2 tablespoons of melted coconut oil. Coconut oil is semi-solid in room temperature. You can warm it up to a liquid in a microwave, or in a double-boiler over a stove.
4. Mix the coconut oil with the dry ingredients until everything is incorporated.
5. Add about 5 spritz of witch hazel or water into the mixture. Don’t pour witch hazel or water directly into the bath bomb mixture. It’s better to use a spray bottle for this step, because that way you won’t add too much water and make the mixture too soft to be molded int0 donut bath bombs.
6. To see if the mixture is ready for molding, place a small amount of it in your hand and squeeze as hard as you can. If the mixture can hold its shape after you open your hand, then it’s ready to be molded.
7. Tightly pack the mixture into the donut pan. I like to use my fingers to press the mixture into the pan. The tighter you pack the bath bombs, the easier they will come out of the pan later.
8. Once you’ve packed the mixture into the donut pan, allow the bath bombs to dry inside the pan for about an hour.
9. After an hour, place a cutting board on top of the donut pan and flip the donut pan upside down.
10. Next use a silicone spatula to gently tap the bottom of the donut pan, which is now facing up after you flipped the donut pan upside down. The tapping will loosen the donut bath bombs from the pan, making them drop onto the cutting board.
11. Set the DIY donut bath bombs aside and begin making the frosting.

How to Make Sugar-Free Frosting for the DIY Donut Bath Bombs

1. Mix 1/2 cup of baking soda, 1/4 cup of citric acid, and 1/8 teaspoon of red mica. I like to use red mica to make pink frosting, but you can use mica that has a different color. Be creative, the sky’s the limit.
2. After combining the dry ingredients, add 1/3 cup of coconut oil and mix some more.  When your dry and wet ingredients are well incorporated, use a piping bag to pipe the frosting onto the donut bath bombs. If you don’t have a piping bag, you can use a zip lock bag. Just add the frosting into a zip lock bag, and make a small cut on one of the bottom corners of the zip lock bag.
3. Finally, after adding frosting, allow your DIY donut bath bombs to dry for a day or two before use.

That’s it! It’s super easy to make your own DIY donut bath bombs. All you need are a few all natural ingredients. These donut bath bombs are so cute, and they look good enough to eat! But do they work?  Well, scroll up to my video tutorial above to see how they fizzle and bubble up.
