  • 1 oz. Oat Extract
  • 1/2 Teaspoon Polysorbate 80
  • 1 Spray Bottle with Witch Hazel

Step-By-Step Instructions for making an Oatmeal Bath Bomb!

Step 1:

Firstly, take one of you mixing bowls and add your dry ingredients. This includes you baking soda, citric acid, SLSA, cream of tartar, and colloidal oatmeal. If you’re using the fine grain ingredients, there may not be a need for a sifter, however it is an option.

Simply rubbing the ingredients through your hands as you mix should also break up any clumps. Additionally, you can use a stand mixer, which will speed up the mixing process.

You can add mica if you want some added color to the bath bomb. However, in this recipe, we did not add any colorant, they will simply be an off white color.

We recommend you wear gloves and proper safety attire when making any sort of bath treat!


Step 2:

Secondly, add your wet ingredients to another mixing bowl. Shea butter, you’ll have to first melt down. Perform 15-20 seconds burst’s in the microwave to melt.

After, you’ll combine your sweet almond oil, fragrance oil, oat extract, polysorbate 80 and finally, the Shea butter you melted.

Next, mix these ingredients well.


Step 3:

Now, add your wet ingredients to your dry mixture and start to blend in your hands. Otherwise, you can also use a stand mixture, but we like doing these smaller recipes by hand. This will allow you to get a better feel for the texture and correct consistency.

Surely, if your new to bath bombs, getting familiar with your ingredients is a must!


Step 4:

At this point the mixture may not be quite ready for molding process. This is where your spray bottle of witch hazel comes into play.

Start with 3-5 sprays at a time. Add your sprays and immediately begin to mix well. Once you’ve mixed a bit, check your consistency again. If it feels to dry, add a few more sprays. Then, repeat this process.

If you’ve read our other blog posts about bath bombs or shower steamers, you will know that to make sure you have the right consistency, you can do a drop test.

Besides simply grabbing your mixture and squeezing to test consistency, squeeze and drop the mixture from about 6-8 inches above your bowl (mixture). If it stays together, without crumbling apart, this is usually a sign your ready for molding.


Step 5:

Now that your mixture has the correct wet to dry consistency, take one-half of your mold in your hand.

Optionally, you can first place real oatmeal at the bottom of your mold first, before adding any mixture. It depends if you want the oats floating in your tub at the time of using your oatmeal bath bomb. However, it does give the bath bombs a more elegant appeal.

Next, scoop up a large amount of mixture into your mold (half), overflowing the one-half of your mold. Lightly press on the top of the mixture. Consequently, don’t pack the mixture to hard since you’ll be pressing the other side together with this one.


Step 6:

Afterwards, take the other half of the mold and do the same.


Step 7:

Press the molds together, try not to twist, just a firm press and hold will do. Press hard for a few seconds, then tap the top of the mold to help release the mixture from the sides of the mold. For instance, you can simply use a large wooden spoon from your kitchen.


Step 8:

The top piece should come off relatively easily, but if not give it a few more taps.

At this point, the top half of the bath bomb is exposed and the bottom mold is still on. Try tapping the bottom half of the mold, then simply flip it over into your other hand.

It should come out nice and easily. Now, place the finished DIY oatmeal bath bomb on a soft surface, like egg carton foam.

Tip: Some recipes call for bath bombs to stay in the mold for a few minutes, up to a few hours. If you have the right consistency, you really shouldn’t have to do this.


Step 10:

Let dry 48 hours in a low humidity environment. If giving this as a gift, DO NOT shrink wrap right away, as this could trap moisture inside.

Place in a warm bath slowly, letting it rest in the palm of your hand while you lower it into the water.
