DIY Cupcake Bath Bombs

Almost everyone loves a bath after a long day. A good book and bubbles can add a nice touch to your bath. But, if you really want to take your bath experience to the next level try adding a bathbomb. Bath bombs come in many shapes, colors and sizes, They have a fun fizz to them.They smell great, and leave your skin so soft. I’ve tried many bathbombs. Currently, I am just in love with the DIY cupcake bath bombs. They are adorable.

These cupcake bath bombs are not only adorable, you can make them yourself. These DIY cupcake bath bombs are not difficult to make and they are filled with goodness. When you make your own bath bombs you can add your favorite essential oils which smell so good. Another benefit to making your own DIY bath bombs is that you can choose the colors that you use.

You can also use a variety of oils in your DIY bathbombs. This recipe inparticular uses coconut oil which is magnificent for your skin. I like the smell of coconut oil. I think it add a delicate coconut smell to the bathbombs. If you don’t like it, you can substitute your favorite oil instead.

I don’t know about you but I like that when I make things at home I know the ingredients. I can customize the scents and colors to what I like or what I’m in the mood for. When you buy bath bombs at the store you are stuck with how they made them. You cannot customize the scent, color, or shape of the bath bomb. Also, when you make something yourself, you have a sense of pride in knowing that you can indeed make things for yourself as well as for others.

Bath bombs are not only great for you. They make great gifts. What better gift to give someone on their birthday than a cupcake bath bomb. Really you can give these as gifts for any occasion or keep them all for yourself. The choice is really yours.

Bath bombs are also great to make with your kids. I started making bath bombs a few years ago with my daughter and we just had so much fun. The first bath bombs that we made, we used the round molds. They turned out good our first time making them, but they turned out great the second time we made them.

If you are like me, you like to make the most of your money. Store bought bath bombs can cost from 5-15 dollars each. Luckily, you don’t have to spend your hard earned money on store bought bath bombs. With this recipe you can make your own bath bombs for a fraction of the cost. So, are you ready to get started?

Cupcake Bath Bomb Recipe (makes 12)

I like to always start with the materials that I will be using for a recipe. It is just so nice to have everything all ready to go before I start on the ingredient list. Also, I don’t know about you but it seems like some things just seem to hide from me in my kitchen. So, gathering what I will need gives me the chance to relocate those misplaced items.

This recipe calls for materials that you probably already have in your cabinets and drawers. If you are missing any of the materials they are all pretty easy to find at your local store or online.

I always wear an apron when I make bath bombs. I didn’t add it to the material list because not everyone owns an apron. You don’t necessarily have to wear an apron but I would advise wearing an old t-shirt or something that you don’t mind getting stained. I’m pretty messy and the oils and colorings that this recipe calls for are not the easiest to remove from your clothes.

While bath bombs can be placed in any kind of mold. This recipe calls for the use of a muffin pan to give the shape of a cupcake. People have asked if you can use a mini muffin pan. I have never used a mini muffin pan for this recipe but I don’t see why your couldn’t. I don’t know if you can find silicone muffin cups in the mini muffin size. I know that you can find the foil muffin cups in the mini size. So, you could give it a shot if you are feeling adventurous.


  • 12 cup Muffin pan
  • Large mixing bowl
  • Muffin cups- I like to use the silicone muffin cups because they are easier to get the bathbombs out of.
  • Disposable gloves-These are optional but I really like to use them.
  • Measuring cup
  • Measuring spoons
  • Spoon- I like to use a wooden spoon.
  • Spray bottle

Now it’s time to gather up all the ingredients that you will be needing. You likely already have most of these ingredients in your home. The ingredients that you will need to purchase will not be hard to find. That is one thing that I love about this recipe the ingredients are so easy to find. I have made things in the past and had to spend a fair amount of time finding the ingredients that I needed for the recipe. That really isn’t much fun and when you have to chase down the ingredients, it takes away from spending time doing what you you like to do.

Cupcake Ingredients

  • 1 1/2 cup Baking soda
  • 1 cup Citric acid
  • 1/2 cup Epsom salt
  • 1/2 cup Cornstarch
  • 1/4 cup Coconut oil
  • 2 tsp Vanilla extract or you can use 5- 9 drops of essential oils
  • Food coloring (liquid or gel) a few drops or a couple tsps of pigment powder
  • Witch hazel or Water in a spray bottle
  • Cooking spray

Step 1

Mix the baking soda, citric acid, epsom salt and cornstarch together in a mixing bowl. Use your hands to break up any clumps. You will want the texture to be free of clumps and well blended. At this stage your mixture should resemble sand. It should move freely through your hands.

Step 2

Add the coconut oil. vanilla extract or essential oils, and the food coloring. Use your hands or the wooden spoon to mix up the ingredients until they are blended together well. The mixture will start to resemble wet sand at this point. It will look like wet sand but it may need a bit more moisture. It really just depends. We will address that in step 3 so in this step just keep blending with your hands to make sure it is all mixed up nice.

You will also want to smell the mixture. If it doesn’t smell as strong as you would like add more scent at this step. Be sure to check the color. This is the stage where you will add more color as well. Remember once you get to step 3 it will be too late to add more scent or color.

You will notice in this recipe there isn’t a precise measurement of the color needed to be added. The reason for this is that it can be tricky to put one measurement for all different colors. If you want a pale color you will add less. If you want it to be more vibrant you will add more. It depends on your preference and the color that you choose.

Step 3

Pick up the mixture in your hands and try to form it into a ball. If the mixture will not stick together like wet sand you will need to add a few sprays of the witch hazel until you can achieve this. Sometimes it will stick without the witch hazel. Also, you don’t have to use witch hazel. You can use water which works fine. I have found that witch hazel works better though.

You may be a little confused at this point about the water. Well, it depends on humidity. If you live in a dry climate you will probably always need to use some water. If you live in a climate that is sometimes very humid and other times not so humid then the number of sprays will vary.

Step 4

Spray the silicone muffin cups with cooking spray. You may think this is weird and it probably is but the cooking spray will really help the bath bombs to release from the silicone cups. The first time I made bathbombs. I didn’t do that and they were really hard to get out of the molds. I have also rubbed coconut oil into the molds or muffin cups and it worked well but when you consider the price cooking spray is much cheaper than coconut oil.

Divide the mixture evenly into the 12 silicone muffin cups. Make sure to press the mixture into the muffin cups and smooth out the tops.

Step 5

Allow the mixture to dry for 24-48 hours. This may seem like a long time but it really isn’t. The longer you let your bath bombs cure the better they will be. I sometimes let mine cure for a week and they are great. If you use them to soon they will not have that great fizz that makes bath bombs so popular.

Step 6

Carefully remove the bathbombs from the silicone muffin cups. You may want to use a soft hand towel during this step as you will want to be very delicate with the bath bombs. No one wants a broken cup cake.

Frosting for Cupcake Bath Bombs


  • Measuring cup
  • Measuring spoons
  • Electric mixer
  • Piping bag
  • Frosting tip


  • 4 oz Confectioners sugar
  • 1/4 cup meringue powder
  • 1 tsp cream of tarter
  • 7 TBSP Water
  • Food coloring

Step 1

In a mixing bowl combine the meringue powder, cream of tarter and powdered sugar.

Step 2

Pour in half of the water along with the vanilla extract and the food coloring.

Step 3

With your mixer set on a low speed begin mixing the ingredients. As the ingredients mix together turn your mixer up to whip and slowly add the remaining water. Whip until it is the consistency of frosting. It should be stiff. If you need more water add more water slowly one tsp at a time.

Step 4

This is the fun part. Once your frosting is finished you will want to put it into your piping bag and get those cupcakes frosted. Once you have frosted the cupcake bathbombs you can add your sprinkles for the finishing touch. This step is my favorite. You can add sprinkles, jimmys, glittery sprinkles, colored sugars. In decorating your cupcakes the possibilities are endless.

This frosting hardens quickly but give them another day to set. The more time you give them to set the better they will be.

Step 5

This is also a fun part. Now your bath bombs are ready to be packaged. You can package them anyway you would like. I have purchased the clear plastic bags to drop them into. I then tied pretty ribbon and made a bow, which I must admit looked pretty eye catching. You can also just wrap them in plastic wrap and put them away to be used by you or you can always give some as gifts. The great thing about wrapping them in plastic is that you can always dress them up and package them later for what ever use you may have for them.

Step 6

Enjoy! Take a long bath and enjoy the result of all your had work. You’ve worked hard on these. Now it is time to try them out. Run a hot bath and plop a DIY cupcake bath bomb into the water. You will not be disappointed. They have just the right amount of fizz. Fizz really is what makes the bath bomb great after all. As you relax you can plan all of the scent and color combinations that you will use in your next batch.
