Making coffee soap is one of my favorite ways to turn something simple into a really useful, skin-loving bar. If you’ve ever wondered why you’d put coffee in soap, the answer is pretty simple—it works.
Coffee grounds add a gentle exfoliation that helps remove dead skin cells and leaves your skin feeling smooth and refreshed. They’re gritty enough to scrub but not harsh, which makes them perfect for everyday use—especially for hands.
If you’re new to cold process soap making, you might want to start with my beginner guide on how to make cold process soap at home.
☕ Why Add Coffee to Soap?
Coffee isn’t just for your morning cup—it brings some real benefits to handmade soap:
- Natural exfoliation
- Helps remove kitchen odours (garlic, onion, fish)
- Adds natural colour (no dyes needed)
- Contains antioxidants for skin support
- Gives a rich, warm scent
Use the recipe below to make your own DIY Coffee Soap
Using the basic recipe #1 – this is one of my best cold process recipes
- 1800 Grams Olive Oil
- 450 Grams Coconut Oil
- 300 Grams Palm Kernal Oil
- 250 Grams Palm Oil
- 250 Grams Grapeseed Oil
- 420 Grams Lye (Sodium Hydroxide)
- 4.5 Cups Water
Additives
- ½ cup used coffee grounds
- 2 oz coffee fragrance oil
If you’re still building your setup, this is a good place to use a digital kitchen scale for soap making to keep your measurements accurate.
☕ How to Make Coffee Soap
- Brew your coffee and save the used grounds (let them dry slightly).
- Prepare your lye solution safely.
- Melt and mix your oils.
- Bring both to around 100°F (38°C).
- Blend to trace.
- Add your coffee grounds and fragrance oil.
- Pour into molds and insulate.
- Let sit 24–48 hours, then cut and cure for 4–6 weeks.
A good immersion stick blender for soap making makes reaching trace much easier and more consistent.
☕ Optional: Use Coffee Instead of Water
For a darker bar and stronger coffee feel, you can replace your water with brewed coffee.
Tip: Freeze your coffee into cubes before adding lye to prevent scorching.
