The most delicious soap recipe ever!
Warning! If you’re a coffee lover, you’ll find it difficult to resist our new soap recipe! The Barista Bar is inspired by the artful swirls of colour in our favourite caffeinated or chocolatey beverages. And then there’s the enticing aroma of this homemade soap! It’s sweet and chocolate-scented with the bright acidity of coffee. How could you resist?
Because this confection also has to be a sweet treat for your skin, we chose saponified oils that gently cleanse and lather up beautifully along with a superfatting oil that nourishes and protects fragile skin. Not only is it delightful to use, it’s also fun to make. We love this recipe’s special technique, which gives each decorative handmade soap a one-of-a-kind pattern. We were so in love with the results that we made a few batches for ourselves!
In short, the delicious aroma, unique pattern, and fun technique of the Barista Bar have thoroughly charmed us. The Barista Bar is a treat for all your senses!
How to make cold process soap… like a real barista!
Before you begin
Warning! This recipe contains two ingredients that accelerate trace: cocoa absolute and bezoin essential oil. The ratio of water to sodium hydroxide has been adjusted to two to one so that the soap doesn’t reach trace too quickly when you add the scents. Be aware that as soon as you’ve added them, you’ll have to work fairly quickly so that soap doesn’t solidify in your measuring pitchers!

Good to know!
- *At Coop Coco, we proudly and exclusively offer our customers high-quality, sustainable, and equitable organic palm oil, imported from reliable and trusted producers from South America that are certified by the RSPO (Roundtable on Sustainable Palm Oil). The RSPO is a non-profit organization that oversees the sustainable production of palm oil, including legal, environmentally appropriate, and socially beneficial management and operations.
- Macadamia oil was chosen as the superfatting oil because it is restructuring, nourishing, protective, and softening, making this homemade soap perfect for winter’s arrival!
- The saponified oils bring their own beautiful properties to this soap recipe:
- Coconut oil hardens soap, cleanses, and provides great lather.
- Palm oil hardens soap and provides silky, creamy lather.
- Olive oil makes the soap milder.
- Kokum butter hardens the soap and provides a creamy, stable lather.
- Don’t hesitate to change the colour of your homemade soap! The combination of hues here was chosen to recreate the effect of a gourmet hot chocolate or latte, but it’s entirely possible to create the same swirling pattern with other colourants.
Steps to follow
- Prepare and disinfect your equipment and workspace.
- Take the necessary precautions for handling sodium hydroxide safely.
- Prepare the sodium hydroxide solution: weigh the water in a Pyrex measuring cup or HDPE pot, weigh the sodium hydroxide, pour the sodium hydroxide into the water, mix well, and set aside to cool.
- Weigh the coconut oil, palm oil, and kokum butter in a large bowl. Melt on the double boiler.
- Weigh the olive oil in a small bowl.
- When the coconut oil, palm oil, and kokum butter have melted, remove from heat. Add the olive oil and mix with a spatula.
- Weigh the macadamia oil in a small bowl and set aside.
- Weigh the essential oils and the cocoa absolute in a ramekin.
- Weigh the colourants for colours 1, 2, and 3 in three separate ramekins.
- Add the pigments for colours 1, 2, and 3 to three measuring funnel pitchers and add a bit of the macadamia oil (from step 7) to each pitcher. Thoroughly crush the granules of colourant with the small silicone spatulas to prevent clumps from forming.
- When the oil and butter mixture and the sodium hydroxide solution have both cooled to 30–35 °C, pour the sodium hydroxide solution into the oil mixture, while stirring with the spatula. Mix with the immersion blender and spatula: set the blades of the blender at the bottom of the bowl and use the spatula to stir around the blender. Mix until homogeneous. If the liquids are still too hot, you can place the containers in a cold water bath to bring the temperature down more quickly.
- Do not wait to reach trace. As soon as the mixture is homogeneous, add the superfatting (macadamia) oil and the essential oils and absolute mixture. Mix with the spatula and immersion blender to combine.
- Fill the fourth pitcher (the one without pigments) with 500 ml of the soap batter.
- Pour 100 ml of the remaining mixture into each of the three pigment-containing pitchers. Disperse the pigments thoroughly with the small spatulas.
- Pour the contents of the pitcher containing colour 3 (white) into the middle of the pitcher containing the unpigmented batter. To do this, begin pouring the white soap batter from fairly high above the pitcher so that the white batter penetrates down into the unpigmented batter. Gradually move the pitcher closer as you pour, so that the white soap batter is deposited at the surface of the unpigmented batter at the end.
- Pour the colour 1 batter (cocoa) on the left side of the white batter, following the same instructions: start high at first, then move closer to the surface of the batter as you pour.
- Pour the colour 2 batter (light cocoa) on the right side of the white batter, following the same instructions.
- Gently pour the soap batter into the molds. The colours will mix on their own to create the desired pattern.
- Cover the soap. After 24–48 hours, unmold while wearing gloves. Leave your homemade soap to cure in a cool, dry place for four to six weeks.
