How to Make Natural DIY Rose Milk Bath Bombs

Stir the baking soda, citric acid, rose clay and milk powder together, making sure to work out any clumps with your fingers, as needed.

Melt the cocoa butter and stir into the dry mixture, along with essential oils, if using.

Your mixture should look something like this:

If incorporating rose petals (optional):

Grind the rose petals in a coffee grinder to a powder and sprinkle a small amount in the mold.

Spritz the bath bomb mixture with witch hazel and mix well with your hands.

A common cause of bath bomb failure is using too much liquid at this stage. Humid weather can also cause issues.

Our house is currently very dry (from our wood stove) and I used 10 spritzes of witch hazel.

During humid summer weather, I may only need 6 or 8 spritzes for this recipe. Start out with just a few spritzes and add more, if needed, as you go.

When the mixture is just right, try making a test ball with your hands and see how it holds. If it doesn’t want to stick together, add a tiny bit more witch hazel.

Pack the mixture into half of the mold, pressing lightly as you go, until it’s somewhat overfull.

Next, fill the other half of the mold, until packed lightly and slightly overfilled. (In the photo below, I actually packed a little more tightly than usual, so you can go lighter than that.)

Fill both sides of the bath bomb mold

Press the two halves together, cleaning out any extra bits that squeeze out from the edges with your fingers. Try not to twist the mold as you do this, as that can break the bond between the two halves.

If the two sides don’t want to stick together, try scooping the mixture back out of the mold and add one to two more spritzes of witch hazel before trying again.

Press both sides together

Remove one side of the mold and make sure it holds together. It will be less fragile to handle once it’s completely dried.

Take off one side of the bath bomb mold

Your bath bomb will look something like this, if it doesn’t have rose petals:

Or, like this, if you did add ground rose petals:

Place the bath bombs on a towel to dry and completely harden for 24 hours.

    We have that book in our local library and I have used it several times. It’s on my ‘need to buy’ list.

  • Tammy says:

    I really love this idea and I am going to try this. Will make really nice Mothers Day gifts. Pinning and thanks for sharing

  • Christina Curtis says:

    I bought the 101 easy handmade products books (both ebook and then hard copy which I found in a bookshop all the way in Perth Western Australia – it’s not the same for me just printing off the ebook lol). Amongst other things, I have made the Rose Face Cream and it is awesome. Can’t believe the pink colour is holding just from my red rose petals- thought it might go brown. Giving the second jar to my 85 yo mum and planning to make more for my mature age friends. Thanks so much for all your hard work and sharing.

  • M. says:

    Beautiful Can’t wait to try this one. thanks for sharing.

  • Jennifer says:

    Could silicone molds be used instead of these?

    • Hi Jennifer! You can use some silicone molds for bath bombs, but it depends on the mold. Some are little too bendy so the bath bombs are prone to breaking when you unmold. You could always test a mold out by making one bath bomb in it and if it breaks, have a sturdier mold on standby to quickly scoop it into. :)

  • Anna says:

    I followed the recipe, and the next morning my bath bombs were cracked. Any idea how to prevent this going forward?

    • Hi Anna! Cracks are sometimes a moisture level problem. If your work area is too dry and warm, then sometimes the bath bomb will crack as it dries out. On the other hand, if the mixture was too wet when molding, it could cause cracks as it expands. If it was from too much moisture, you might also see little wart-like bumps all over. Did the bath bomb also flatten out on the bottom, or did it stay round? Also, larger bath bombs are more prone to cracking from their weight, where small and medium ones are sturdier. Bath bombs can be quite finicky sometimes!
