Farm-Fresh, Simple, Effective Skin Care -- Handmade by YOU!

Recipe: Raspberry Truffle Bath Bombs

Of all the DIY skin care products I make, I have a secret obsession with bath products. Maybe it's because the promise of a long relaxing soak is so appealing.

Although I don't always have the time for that long relaxing soak, so there is literally an entire cabinet in the master bathroom filled with handcrafted bath products. I have enough to last for many, many months. But still I make more! Because when an idea pops into your head, how can you not jump on it?


That's exactly what happened with this bath bomb. The Raspberry Truffle fragrance oil was just begging to be used. I imagined a delicate, feminine bath bomb and I think it turned out super sweet. What do you think?

If you've never made bath bombs before, they can be a little tricky.  Read through the entire recipe first, to get familiar with the process, before getting started. I'd also recommend doing a small test batch first, to get the feel for it.  

Ready to make some Raspberry Truffle Bath Bombs? 

Here's what you'll need:

1 cup baking soda

1/2 cup citric acid (you can usually find this at the health food store, too)

1 tablespoon cornstarch

1/2 cup Himalayan pink salt, fine grain (you can substitute sea salt or Epsom salt)

1 teaspoon grapeseed oil

3-4 drops red soap colorant OR food coloring

1/2 teaspoon Raspberry Truffle fragrance oil (or any fragrance that you please)

Dried flower petals (I used a combination of heather flowers and jasmine buds, but you can use any dried flowers you like: rose petals, chamomile, lavender, are all pretty options) 

spritz bottle filled with witch hazel

You'll also need:

wax paper or freezer paper
large bowl

rubber spatula or whisk

rubber gloves (to keep your hands from becoming stained from the colorant and protect your manicure)

heart-shaped mold (I used silicon baking cups, but you can also use a bath bomb or soap mold) 

Silicon baking cups work perfectly for this recipe.

Step 1: I like to start by covering my workstation with wax paper or freezer paper, taping the corners down to keep it in place.  Making bath bombs is a messy business and this makes clean-up super easy!

You'll want to keep a section of your freezer paper available to set your newly made bath bombs on to dry.  

Step 2:  Prepare your molds by sprinkling a bit of dried flower petals into the bottom of your molds.  Set these out of the way for now.  

Step 3:  Measure out baking soda, citric acid, and cornstarch into your bowl.  Mix them really well, making sure that all clumps are gone.

Step 4:  Stir in Himalayan pink salt and grapeseed oil.  The grapeseed oil will clump, so put on your gloves and really work the grapeseed oil into the mixture until it's well blended.

Step 5:  Now the real fun begins -- coloring your bath bomb!  Add 3 to 4 drops of colorant into your mixture.  It will fizz a bit, that's OK.  Just stir in quickly.

The colorant won't want to mix into the blend at all, so you'll have to use your hands again!  Rub the mixture between your hands and you'll start to see your white blend turn a lovely shade of pink.  Keep mixing until the colorant is completely blended into the mixture.

Don't be tempted to add more colorant.  Add too much and you'll stain your bath water (and your skin, and towels) when you use your bomb.

Step 6:  Stir in your fragrance oil.  Again, you'll probably need to use your hands to blend.

Step 7:  Lightly spritz your mixture with witch hazel and stir well.  You're looking to get your mixture the consistency of slightly damp sand.  It should be damp enough to clump together when squeezed in your hand, but not so wet that it starts to fizz.  Take your time, lightly spritzing and mixing until you get the right consistency.

Step 8:  Carefully fill the prepared mold with the mixture.  Press down firmly and evenly.  You can use your fingers or spatula to smooth out the top.  Continue to fill all of the molds.

Gently remove bath bombs from the mold.  They will still be squishy, but will harden as they dry.

Step 9:  After all of your molds are filled, it's time to unmold!  Yes, already.  If you let your bath bombs set in the mold until fully dry, they'll be hopelessly stuck.

Turn your molds over onto the freezer paper and gently press to remove the bath bomb.  Work carefully, your bombs are still delicate.

Once the bath bombs are safely out of the mold, don't move them!  They'll most likely crumble.  Let them set, undisturbed, for about 12 hours or until completely hardened.

Step 10:  When your bombs are completely dry, you can safely move them and package them.  Aren't they amazingly cute?


To use your bath bombs, simply drop one into warm bath water.  It will fizz and release all the goodness into your tub (plus a delicious fragrance).  Soak for at least 20 minutes.
