Instructions 

  • Make the lye and coffee solution. Measure out the lye and coffee in separate containers using a digital scale. The coffee must be cooled to room temperatue. Carefully add the lye to the coffee and stir until it is fully dissolved. The liqiud will shoot up in temperature and give off a burned coffee smell. Set aside to cool in a safe place.

Coffee Soap Benefits

Using homemade coffee soap offers many benefits for various skin types. The natural caffeine present in coffee can improve blood flow and help reduce the appearance of cellulite. Coffee grounds serve as an excellent exfoliant, helping to remove dead skin cells and rejuvenate the skin.

Coffee Soap Tips

  • Essential oils such as lavender or vanilla can be added at trace to enhance the fragrance of your soap.
  • Make sure the coffee is cooled to room temperature before adding the lye.
  • If you want a coffee fragrance, be. sure to add a fragrance oil at trace.
  • The soap will be brown no matter what you do, but you can add a little titanium dioxide or black pigment to get darker or lighter swirls.
  • For best results, use fresh coffee grounds for exfoliation.
  • A coffee grinder can be handy for grinding whole coffee beans to the desired consistency.
  • If you’re concerned about unpleasant odors from the lye, consider adding tablespoons of vanilla extract to the mix.

I recommend Nurture Soap for the best selection of colorants and fragrances.

Storage Instructions

Homemade soap is happiest in a cool, dark place with plenty of air circulation. I like to put it in a cardboard box with newspaper and tuck it on a closet shelf.

For gifting, wrap the soap in decorative paper and attach gift tags for a personal touch.

It will last forever if stored well.

Substitutions and Variations

  • For a second option, try a goat milk soap base for a creamier texture.
  • You can also use a melted soap base and add extra coffee grounds for more exfoliation.
  • Consider trying a vanilla coffee soap by adding a tablespoon of coffee grinds and a few drops of vanilla essential oil.

FAQs

What are the best coffee beans to use for soap?

It doesn’t matter. Just use what you have on hand. If you have a type of coffee you don’t like anymore, use that!

Can I use instant coffee in this recipe?

Yes, you can!

Will the soap have a coffee smell?

Nope. The finished bar has no fragrance.

Will the coffee make the soap behave badly?

No, since there is no sugar in the coffee it will behave just like water when you add the lye. You’ll notice the scorched smell and (obviously) the color, but that’s it.

Can I use a different type of base oil?

Yes, you can substitute the base oils. For instance, using cocoa butter instead of shea butter can provide different moisturizing properties due to its rich fatty acids.

What can I do with leftover coffee grounds?

Used coffee grounds can be added to your soap mixture for additional exfoliation. They can also be used to make a coffee soap scrub.

Making your own coffee soap at home is a great way to enjoy the benefits of coffee for your skin. This simple recipe uses ingredients you likely already have, and the process is straightforward. Whether you’re looking to exfoliate, improve skin texture, or simply enjoy the smell of coffee in your soap, this recipe has you covered.

Remember to follow the instructions carefully, especially when handling lye, to ensure your handmade soap turns out perfectly. With a little patience and practice, you’ll have beautiful, moisturizing bars of coffee soap that make great gifts or a special treat for yourself. Happy soap-making!

    HI! I would love to try this soap today however, I do not want to use palm oil. What else can i use? Can i add more olive oil?

  2. Any alternative to using lye?? And the base I have is a melt and pour shea/mango butter combo. Would that work too?

    1. hi amanda, you can’t make your own soap without lye but if you want to use the soap base you have, you definitely can! I would use a little instant coffee and mix it with liquid glycerin and add to the melted base. then add the coffee grounds.

    Hi,

    I tried this recipe today—followed it as exactly as I could—meaning I didn’t sub out anything. However, not 15 minutes after pouring into the mold, it got too hot and cracked along the length in the center. I am sort of new to soap making; I’ve made around a dozen or so batches, and most of the other recipes have advised me to cover/insulate, or even place a heating pad under the mold as it goes through the gel phase. . . I noticed you didn’t give any direction along those lines, so could that be the reason it overheated and cracked?? If you could advise how to avoid that in the future, much appreciated! Crack or no crack—im looking forward to enjoying this soap! Thank you so much!

  4. I am new to CP soaping ….. If I don’t have palm oil, do I need to reconfigure in a soap calculator if I wanted to sub it out for an avocado or hemp seed oil – to make sure the lye amt will still saponify correctly?

    1. yes that is exactly right 🙂 i’d recommend subbing the amount with 75% olive and 25% shea then recalculating… avocado with be quite expensive and a softer bar

    I made this recipe last night at 8:00 p.m. I unmolded it this morning at 10:00 a.m. and cut it around 11:00 a.m. it is soft but I set it to cure. I grabbed an end slice and took it to the shower with me this morning. Not even 24 hours old yes I know I’m a bad girl. But let me tell you this was the most luxurious beautiful soap ever!
