French Macaron Inspired Bath Bombs

  • Difficulty:Intermediate
  • Time:1 hour
  • Yields:10 Bath Fizzies

If you follow me on Instagram, you’ve probably noticed the Bramble Berry office is full of French Macaron fans. We’ve had them as snacks during meetings, been treated to homemade ones by our fabulous Customer Care team member Tina, and served them as treats at the Soap Crafting release Party a few weeks ago. They are sweet little meringue morsels made from just a few simple ingredients, and we knew we had to try them in soap. Our bath treats are made from bath fizzies and foaming bath whip instead of eggs and sugar, but we hope you enjoy them all the same. PS – I know they look more like ice cream cookie sandwiches, but macarons were my inspiration; I promise!

What You’ll Need:

For the bath bombs:

1 cup Citric Acid

2 cups Baking Soda

2 tablespoons melted Shea Butter

4 tablespoons Kaolin Clay

6 mL Mango Mango Fragrance Oil

3 mL Cantaloupe La Bomb Colorant

Witch Hazel

Droppers

Two 12-bar Round Silicone Molds

For the frosting:

20 oz. Foaming Bath Whip

5 oz. White Melt and Pour Base

2 mL Almond Cybilla Fragrance Oil

2 mL Vanilla Color Stabilizer

Disposable Frosting Bags

4B Frosting Tip

ONE: Start by pouring the Baking Soda and Citric Acid through a strainer to work out clumps. This will ensure your mixture is nice and smooth and free of clumps. If chunks get left behind, use a spoon to break them up and sift them through the strainer.

TWO: After you’ve mixed the Citric Acid and Baking Soda, add the Kaolin Clay.

THREE: Mix the powders together and then add the Mango Mango Fragrance oil. To fully disperse the fragrance oil, put on some gloves and handmix the powders and oil together.

FOUR: Now add the Cantaloupe La Bomb colorant. We added 3 mL, but the colorant is WYSIWYG (what you see is what you get) so you can add a bit more if you’d like a more saturated color. Keep in mind – the more colorant you add, the higher the chance that it will color the bath water.

FIVE: At this point you’ll definitely want to put on some gloves to full incorporate the color into the powders. The colorant will tend to clump together so don’t be afraid to break up the chunks with your fingers. La Bomb colorants are specifically formulated to work in bath bombs, and if you’ve never used them before you should check out this blog post.

SIX: Melt down the Shea Butter in a heat safe container on 20 – 30 second bursts. When the butter is fully melted, add it to the powder mixture and stir.

SEVEN: At this point, the powder should start to clump together. You don’t want it so crumbly that it won’t hold a shape, but you also don’t want it to feel saturated. If you find the mixture is crumbly, spray 2 – 3 pumps of Witch Hazel into the mixture. The Witch Hazel will help the powders stick together without setting off a reaction and making the mixture fizz prematurely. Test the mixture by squeezing a handful — if it holds shape and doesn’t fall apart, it’s good to go!

EIGHT: Once the mixture holds shape, scoop about two tablespoons worth of powder into each cavity of the mold. Press the mixture into the mold firmly, making sure to keep the surface as level as possible. Some of the mixture may creep up the sides of the mold as you press — that’s okay, just try pushing it back down. You can clean up the circles in the next step. Once you’ve filled 20 cavities, let the molds sit in a cool, dry place overnight to allow the bath fizzies to harden up.

NINE: After you’ve left the bath fizzies sit, unmold them very carefully. Because they are relatively thin, they can crack and break easily. The best way to get them out unharmed is to gently fold one row of the mold over on itself so the openings of the cavities meet. Then, gently press the bottom of the three cavities facing you, nudging the bath fizzies out of the mold.

If you find that the bath fizzy edges are rough and jagged from finger prints, use a clean up tool to carve and smooth the edges down.

TEN: Set the fizzies aside. For the frosting, use  a heat safe container to melt the White Melt & Pour Base in the microwave on 30 second increments. Once it’s fully melted, combine it in a large bowl with the Foaming Bath Whip.

ELEVEN: Add in the Almond Cybilla Fragrance Oil. Because this fragrance oil can cause discoloration and we want the frosting to stay white, add in an equal amount of Vanilla Color Stabilizer.

TWELVE: Using a hand mixer on a low speed, whip the melted soap base, bath whip and fragrance oil together. After about a minute, turn the speed up to high and whip for another 3 – 5 minutes. Keep a spatula on hand in case the mixture creeps up the side of the bowl. After about 5 – 7 minutes of mixing, the mixture should be able to form stiff peaks. Once it has reached that consistency, it’s ready to use.

THIRTEEN: Cut the triangle tip off a frosting bag and insert a 4B frosting tip. Then, spoon in about a cup of the frosting mixture (Tip: We like using our brand new Square Silicone Spoons!).

FOURTEEN: Frost the bath fizzy by starting in the center and making a circular pattern toward the edge. We piled our frosting fairly high (1.5  - 2 inches) because although the frosting should be stiff, it will fall slightly when you stack another fizzy on top. Here you can get creative! Try stacking another layer of frosting and another fizzy on top for a triple Macaron, or try squeezing the fizzies together so the frosting peeks over the edges. It’s totally up to you!

Your fizzies are ready to use right away. Enjoy!

    I think they’d look even more like macaroons if you’d pack the mix into one of the sphere molds Brambleberry sells! I might try that and experiment with the colors and scents!

    Love the frosting inside!

  2. Meagan says:

    How do these perform as far as the bath whip? Does it bubble or is it more for visual effect?

    • Hi Meagan!

      The foaming bath whip (combined with the melt and pour) will actually bubble a bit when you use in the bath tub leaving your with a nice lather. It gives the bath fizzies that macaroon look while also being beneficial for the user! =) I hope this helps, let us know if you have any other questions.

    This looks like a really fun gift idea…. Thank you!!

    I don’t have any La Bomb colorants…can you recommend some others that will work?

    • Hi Sly!

      We used the La Bomb Colorants because we have found that they work the best in any bath fizzy recipe. If you don’t have any available, you can use micas, but remember not to add too much colorant or you could end up with a ring of color around your bathtub. Be sure to let us know how yours turns out! =)

  4. Sophia says:

    Does the water from the melt and pour soap that is in the frosting react with the citric acid and baking soda at all?

    • Hi Sophia!

      The water in the melt & pour soap doesn’t react at all with the citric acid and baking soda. In fact, the frosting works really well with the bath fizzies! We hope you get a chance to try out this recipe out. Be sure to give us your feedback! =)

  5. Linda says:

    These look great but I was wondering how hard does the frosting in the middle set?

    • Hi Linda!

      This is such a fun project and we hope you will try it out. The frosting in the middle will set-up, but it isn’t going to be rock hard. It will have a spongy-like texture, but stands up well enough to be packaged before use! =)

      P.S. Be sure to share any pictures you get of this project with us on Bramble Berry’s Facebook page. =)

    Could coconut oil be substituted for the shea butter?

  7. Jenna says:

    The frosting works really well to top bath fizzie cup cake bases. The kids love them because I pull the icing off and they play with the base. I smoosh the whip in my hand and make bubbles in the water.

  8. Katie says:

    I made a batch of the frosting and used it for bath bomb cupcakes made with Soapylove’s cupcake mold.
    The cupcakes look great! I whipped the frosting for probably almost 10 minutes.

    From previous posts, it looks like the frosting should harden enough to (carefully) package. If it does, then this recipe is a keeper. I used a teeny bit of BB 1982 Blue Mica to color the frosting and also added BB Apricot Freesia FO to it. Topped it with glitter! Yum!

    • Amanda says:

      Hi Katie!

      So glad the frosting turned out well for you! You’re correct, your frosting should become hard enough for you to package. If you get photos of your project, we would love to see them on our Facebook page, it sounds super cute!

      • Katie says:

        Well, it isn’t hard enough to package in cellophane, but it would hold up in a cupcake box. It still smears and smudges if anything touches it. It looks great, tho’!

        I decided that I wanted something harder (and something that dissolves a bit better in the bath and foams) so I tweaked the Dirty Laundry/BB cupcake bath fizzie frosting. Now that came out fantastic! And I like how it behaves in the tub.

        I may use this post’s frosting from time to time, but I think I prefer the other. Plus, I put a lot of carrier oil in the other, so it’s a nice addition to the bath.

        • Amanda says:

          Hi Katie!

          I’m sure they look adorable! I’m so glad you were able to find a recipe that worked well for you. Sometimes it just takes a little testing :).

          Happy Soaping!

    You did an amazing job! They were amazing in the tub! The kids loved them.

    • Amanda says:

      Hi Laney!

      I’m so glad this recipe worked out well for you! It’s such a fun one, what’s better than enjoying cookies in the tub? :)

    How to store them? Do I need to put them in a fridge? How long can I store them for?
    *** and one more thing, since they look so soft what’s your packaging suggestion?

    • Amanda says:

      Hi Ev!

      They are rather delicate, so I would recommend packaging them in a small bag, with plenty of crinkle paper to keep them from moving around in the bag. You can store them, you don’t need to refrigerate them. I wouldn’t recommend storing them for more than a month or so, I would try to use them as soon as possible :)

    Is there an option for a printable version of the recipe? Thank you. Tara.

    • Kelsey says:

      Hi Tara!

      We actually don’t have a PDF version of this recipe. Sorry about that!

      However, you can copy this recipe and paste it into a Word document if you don’t want any of the pictures. :)

    Is this supposed to be macaroons? I always see macaroons as fluffy clumps. These look more like vanilla wafers oreos. Cute, but not a macaroon. (also, you’re missing an O throughout the article and most importantly, the title. It’s macaroon, not macaron….I kept expecting an I at the end making it macaroni.)

    • Kelsey says:

      Hi Sara!

      You’re right, macaroons are fluffy cookies made with coconut and meringue. Our inspiration was actually macarons, which are made with meringue and ground almond. They’re typically filled with buttercream. :)
