9.75 oz. distilled water
4.25 oz. lye/sodium hydroxide
I’ve included a screenshot from SoapCalc (above) to make resizing the recipe for my DIY donut soap easier and so you have an idea of the overall soap bar quality. (SoapCalc is great tool for anyone wanting to create their own custom soap recipes from scratch. You can learn how to create your own custom soap recipes using a lye calculator here.)
Because my DIY donut soap is palm free, I did a steeper water discount than normal and included sodium lactate in the soap recipe to get a harder bar.
I used a sparkling limoncello fragrance oil for my donut soaps. You can use any fragrance oil of your choosing, however, be aware that if it contains vanilla, your donut soaps will turn brown.
My DIY donut soap recipe yields a baker’s dozen or 13 donut soaps.
I used this 2 pack of silicone donut molds that my boyfriend gifted me for Valentine’s Day to make these soap donuts.
You should be familiar with making cold process soap before trying this soap recipe. If you’ve never made cold process soap before – or any kind of soap in which you’re working with lye – I strongly recommend you start with a beginner soap recipe so you get a feel for the process and know you can create a successful soap. Otherwise, you’ll follow your basic cold process soapmaking instructions to create your DIY donut soap. You should adhere to all basic safety precautions when working with lye.
Begin by measuring out the amount of water called for in the recipe into a heat safe container. Next, use a digital scale to weigh out the lye.
Slowly pour the lye into the water in a well ventilated area. Stir the lye until it has dissolved, then set the lye-water aside.
Next, weigh out the soapmaking fats – these are all of the oils and the mango butter called for in the recipe.
Heat until melted then set aside.
Allow the lye-water and the melted soapmaking oils to cool to around 95°F. Once they’ve reached this temperature, you’re ready to make soap.
Weigh out the sodium lactate and stir it into the cooled lye-water.
Then weigh out the clay, watermelon fruit powder and fragrance oil. Add these ingredients to the melted oils and mix to combine with a stick/hand blender.
Now slowly pour the lye-water into the melted oils.
Mix with a stick blender until you reach trace then evenly pour the donut soap batter into the molds’ cavities. Cover if desired with plastic film or parchment paper and set aside in a safe location.
Remove the soap from your molds the next day or the day after depending on the hardness of the soap donuts. If your soap doesn’t gel then you may need to wait an extra day or two before unmolding to get your DIY donut soap to release cleanly from the molds.
Allow your donut soaps to cure 4-6 weeks. Once your soaps have cured, your ready to add the icing and sprinkles!
To create your soap icing you’ll need a clear melt and pour soap base. I specifically used Crafter’s Choice detergent free hemp melt and pour soap base. Cut up several ounces of the soap base into squares and melt in the microwave in 30 second increments until melted.
Next add your desired colorant for the soap glaze. I used Nurture Soap’s vibrant yellow mica. Stir in desired amount – I recommend about a quarter teaspoon – and scent if desired.
Allow the soap glaze to cool slightly. Just before it starts to solidify, you’re ready to apply the glaze.
Dip your first soap donut, top down, into the soap icing donut glaze. Turn over and place onto a cutting board or other workable surface. Immediately add candy sprinkles of your choice.
Repeat this process with all of the donut soaps one at time, until you’ve decorated all of your donut soaps.
If you prefer to add soap icing rather than a glaze to your soap donuts, simply add more colorant to the clear melt and pour soap base, allow to cool but not solidify, then drizzle as desired across each of the soaps.
You’ve now made your own DIY donut soap! All that’s left is to wrap and label your soaps as desired for personal use or gifting. (These make fantastic party favors!) If you’re planning to sell your homemade donut soaps, be sure to label them according to FDA guidelines. Not sure how to label your creations? I highly recommend the book, Soap and Cosmetic Labeling: How to Follow the Rules and Regs Explained in Plain English, by Marie Gale.
