How to make cupcake soap

As you know, there are many websites and stores making cupcake soap. I was surprised when I first saw that. I made my husband goes crazy cause I’ve been talking about it every morning and night. He never said anything.  He always says whatever make you happy, I am happy. Such a wonderful husband!  🙂 Love you so much.

My first attemption wasn’t good but not bad. After I practiced and get used to, it was fun and easy. I have to mention the name of this woman first. My inspiration came from khun Ann “fly mom” She is Thai but living in America. I visited her blog and really love it. I started to study from youtube and learn how to make a swirl on cupcake. The difficult part of making cupcake soap is the top decoration 🙂 

I, finally, made my cupcake soap  and sell it as a wedding souvenirs as you can see my posted a while ago.

Today, I would like to teach how to make a cupcake soap in my style.  I am sorry once again with my poor english, please be patient! 🙂

First, you need to make a cupcake base. You can use your favourite CP recipe .

– Use the same process just like you make CP soap and when it turns to heavy trace, pour the soap in your prepared mold. This process will take you a day since you have to let it dry before you decorate a cream on top.

– I recommend you to use a plastic or silicone mold. My bad habit is using aluminum foil. Don’t follow me on this. It’s not a good idea but my customer preferred using aluminum foil because it looks nice in a box.

– Stay Away from aluminium containers and equipments. The lye will corrode aluminium stuffs. I have experiences with that.

– Apply some oil into a plastic or silicone mold for easily unmold when it completely dry.

– Measure lye and oil  and cover with a plastic food wrapper to prevent the moist  and it’s dangerous to have your containers wide open.

 Freeze them in refrigerator for 10-15 minutes.

– Please Please be careful if you have small child. You may need to be close to the refrigerator all the time in this process. I am afraid of someone might drink this by mistake. AHHHHH!!! Big problem!

After 10-15 minutes, the oil will go solid and the lye will cool down. I will take the solid oil out but keep the lye in the refrigerator until I finish with the solid oil.

Stir the solid oil until it becomes liquid, then,  add the lye.

Use a stick blender (or you might call hand mixer) blends the soap until medium trace. Then, add colour and fragrance. After you add fragrance, the soap will turn heavy trace very fast and you need to act fast,too. I like using fragrance that makes the soap trace very fast. Wasting my time to wait!  The soap will get sticky just like in the picture.

The soap is ready for next process.

Prepare your cake decorating bags and tips. I use tip no 21.

Pour the soap into a decorating bag. Don’t pour the soap too much in one time. It’s difficult to squeeze it.

Then, start  to make a cream on your cupcake. If you don’t know how to do it, I recommend you to watch in youtube.


You can use M&P clear and white or CP  to decorate your cupcake soap.

If you use M&P, just use a cookie cutter to cut a soap into any shapes. (ready within an hour)

If you use CP, you need to let it dry 18-24 hour then, use a cookie cutter as well.

I, sometime, bought a clay from market and decorate on my cupcake. The reason is the cupcake cream is hot and it melt my heart shape soaps that make from CP. It’s not happen very often though.

  2. ahh your soap looks so cute 😀
    I’m wondering about the temperature of the oils & lye after you put them in the fridge. At approximately what temperature did you mix the oils & lye?

    thanks !

    • HI! I don’t know what’s the exactly degree when I mix the oils and lye. I’ve never checked that but it’s not too cool, otherwise, I think the lye won’t work.

  3. hi there your site is great i am going to practice first but i was trying to find khun Ann “fly mom” blog but cant find it anywhere. Can you help with that. Thanks

  4. I read that you are not sure of the temp of the lye or oils, but did you warm the oils back up to melt them or did you bring them to room temp? I’ve read some posts where they started with cold solid oils such as palm or coconut and slowly added the liquid oils and then the cold lyewater. Is that similar to what you have done?

    • if you make cupcake soap and your oils are solid oils (do not need to melt them), you just put them in refrigerator for 5-10 mins and pour the cold lye water in.
      If you make normal cp soap and your oils are soild oils (you need to melt this oil)

  5. Wow, I’m very impressed with your blog, but I do have a question or rather a request. I’m administrator of a soap making forum which is where I found your picture of your beautiful cupcakes. One of my members who happens to live in the UK has had her customers ask to have cupcake soaps made with the same coloring as yours. The color is stunning I might add. Would you be willing to share the name of the coloring that you used as well as where it might be purchased. Or if we can find something close to it. Thank you for considering sharing this information. You can also email me at or you can find me at the link to our soap forum.


    • Thank you so much Krissy. The color I used I bought from a local market. They said it’s a chemical color for soap making (water soluble) but I don’t know the name exactly. It came in a small package. I will visit your site for sure.

  6. I have made some cupcakes soaps and would like to decorate the top with grated or soapshavings can you please tell me how I can get the soap shaving to stay on top of the cupcake please. Your cupcake soaps are lovely.



    • Hi! I decorated the top of the cupcake when they just finished. So, it will stick on top. Another way is melting some clear glycerin base and attach your decoration on it.

  7. What i do not realize is if truth be told how you
    are not actually a lot more smartly-liked than you may be right now.

    You are very intelligent. You recognize thus considerably
    in relation to this subject, made me individually consider it from so many varied angles.
    Its like women and men are not involved unless it’s something to accomplish with Girl gaga! Your personal stuffs great. Always take care of it up!

  8. im thinking about selling this at a couple of craft fairs.ive been looking around and found some great stuff but this is one of my favorites!thank you!

  9. Your cupcakes are awesome!!!
    I’m a new one to soapmaking and I have two questions for you!
    The first one is what kind of oil did you use in your recipe ??
    And the second is what kind of color did you use ??
    I have read about mica colors, pigment colors, liquid colors,non-bleeding colors…
    What kind of color is that ?


    • Thank you for your message. I’m sorry for the late reply. I didn’t visit my blog for a long time.

      To answer your question, I use several in my soap. I depends on the recipe and how i want then to be like creamy or bubbly. I calculate my recipe in and also I use normal food color in my recipe. I hope this help.
