Super Cute Homemade Cupcake Christmas Bath Bombs with Soap Frosting Post Preview: You’ll find all of the ingredients and directions you need to make cute cupcake bath bombs for any occasion (just pick festive cupcake liners and sprinkles).
While shopping for small gifts for a couple of friends the other day, my teenage daughter said, “When you don’t know exactly what to get, you can never go wrong with bath bombs.”
Indeed – bath bombs are fun. Plus, I love small gifts that can get used up and enjoyed. Nobody needs a bunch of cheap knick knacks or doodads sitting around, unless you really know they’ll love them, of course.
A Few Quick Preemptive Notes about the Christmas Cupcake Bath Bombs:
Here are a couple of quick notes that I wanted you to check out before we got to the recipe and directions for Christmas bath bombs. I didn’t want them to get lost in the shuffle and mention them after the recipe.
They don’t have to be only Christmas-themed
If you’re looking for a project to work on at home for some gift giving, I think you’ll have fun making these cupcake bath bombs. While these are specifically Christmas bath bombs, you can easily change up the cupcake liners and sprinkles choice to better suit them being birthday cupcake bath bombs or bath bombs for any other holiday. I love it when projects can easily be changed to make them more versatile!
If you are making the cupcake bath bombs for a different occasion, you may want to change up the essential oils in the list to be more appropriate for the occasion. The ones in this recipe are more Christmas themed.
Options for Skipping the Soap “Frosting”
On top of the bath bomb portion, there is a soap-based “frosting.” You can skip putting that on if you are happy with more of a puck-shaped bath bomb that isn’t quite as fancy or cupcake-shaped.
Or you can skip the soap frosting part, and use a cupcake bath bomb mold if you still want to keep the cupcake appearance.
Finding the Supplies
For many of the supplies, I have supplied links to them on Amazon to make them easier to find. Most of those links are in quantities larger than you will need for a single recipe of these Christmas bath bombs. You should be able to find most or all of these locally as well though, especially if you have a large craft store.

Super Cute Homemade Cupcake Christmas Bath Bombs with Soap Frosting Recipe and Directions
Okay, so now that we have all of my notes out of the way, let’s make some Christmas bath bombs!
Ingredients and Supplies for Christmas Cupcake Bath Bombs:
- 5 cups baking soda (you can usually buy larger boxes of this at the store, but if you need a source for a larger container, you can get it here)
- 1 cup citric acid (this can be cheaper to buy in bulk)
- 1 cup SLSA (Sodium Laurel Sulfoacetate) (Here it is an organic SLSA option)
- 1 tablespoon of white cosmetic glitter
- 1/2 cup cornstarch
- 1/4-1/3 cup coconut oil
- 5 tablespoons avocado body butter
- 2 tablespoons polysorbate 80
- 10-20 drops of cinnamon essential oil – Remember: if you are making these cupcake bath bombs for a different occasion, you will likely want to change up these essential oils to a different blend, depending on the occasion
- 10-20 drops of clove essential oil
- 1-2 drops of orange essential oil
- 2-3 drops ivory food coloring gel
- Spray bottle of rubbing alcohol
- 1 large mixing bowl
- Muffin tin
- Cupcake liners (Here are some Christmas cupcake liners)
Directions for Cupcake-shaped Christmas Bath Bombs:
1. Add cupcake liners to a muffin tin. Set aside.
2. Add all dry ingredients, including glitter, to a large mixing bowl.
3. Whisk together dry ingredients until fully combined.
4. In a small microwave-safe bowl, melt coconut oil in the microwave for 15-20 seconds. Repeat in 15 second increments until the oil is completely melted.
5. Repeat step three but with avocado oil added this time.
6. Add essential oils to your coconut and avocado oil bowl. Whisk this together.
7. Add a few drops of ivory food coloring and then whisk together.
8. Add the coconut/avocado oil mixture, along with polysorbate 80, to the dry ingredients.
9. Using your hands, break down as many clumps that may be remaining in your mixture. You will know when the mixture is perfect when it feels like wet sand. You will also be able to press the mixture together in your hands and it will stay together.
10. Take a scoop of the bath bomb mixture and add to the muffin tin that you set aside earlier. Continue until all cavities are filled. Press down gently. We used the bottom of a small glass to pack it in.
11. Allow the cupcake bath bombs to harden for at least 24 hours before adding the soap frosting (see directions below) to the tops.
Ingredients and Supplies for Soap Frosting for Cupcake Bath Bombs
- 1/4 cup clear melt and pour soap base
- 3/4 cup whipped soap base
- Vegetable glycerin
- Reusable piping bag
- Large frosting tip (Here is a piping kit that includes bags and tips)
- Orange essential oil (see above)
- Christmas sprinkles
Directions for Soap Frosting Recipe
1. Add whipped soap base and glycerin to mixing bowl.
2. Add cornstarch to the mixing bowl and gently fold into the mixture to avoid it dusting up when you use the mixer.
3. Add the essential oil. (You can change it to a different scent for other occasions, if you prefer.)
4. Melt your soap base in a microwave-safe bowl in 30-second intervals, stirring after each until interval. Allow to cool down to 140 degrees or about 5 minutes.
5. Whip your whipped soap and glycerin mixture on medium speed for 2 minutes and then slowly add in the cooled down soap base. Beat until the mixture forms peaks, just like when you are making a meringue. If your frosting is not stiff enough, add a bit more cornstarch and mix in. Repeat until the mixture forms firm peaks.
6. Add your soap frosting to a piping bag and pipe “frosting” onto your cupcake bath bombs. You must work quickly as the frosting will begin to harden after about 5 minutes. After this point, frosting the cupcakes will become more difficult, so be sure to work quickly.
7. Add a few colorful decorations, if desired. Since these ones are Christmas bath bombs, holiday colored sprinkles were the perfect addition.
8. Allow the soap to harden for a couple of days. The recipient will be able to use the soap portion of the cupcake bath bomb after their Christmas bath bomb has dissolved.
9. Package up your Christmas bath bombs to give as a gift or enjoy them at home!
