Elderflower & Lavender Soap Recipe

Natural cold-process soap recipe and instructions featuring elderflower infusion, rich cocoa butter, and a lavender and herb essential oil blend

by Jan Berry, author of Simple & Natural Soap Making

This natural soap recipe features elderflowers, an old-fashioned home remedy for softer skin, along with lavender essential oil for a relaxing scent. Before you make this recipe, you’ll first need to make elderflower tea. To do so, place about ½ cup fresh elderflowers (or 2 tbsp dried) in a heat-proof cup or container. Cover with 9.5 oz (269 g) simmering hot water. Let steep for around 30 minutes, strain, and cool completely. Weigh out 9 oz (255 g) for the recipe, adding extra distilled water if needed to ensure the correct weight.

Notes & Substitution Ideas

  • Cocoa butter helps add hardness to palm-free soap recipes like this one; if you don’t have any, try using kokum butter, tallow, or lard for a similar effect. Shea butter could also work well.
  • If you wish to replace the sunflower oil, try using sweet almond or rice bran oil instead.
  • If you don’t have bergamot and rosemary essential oil to create the suggested scent blend, try using 35 grams of lavender essential oil instead.

Use fresh or dried elderflowers to make this soap

Step 1: Make the Lye Solution

Wearing protective gloves and eye-wear, carefully stir the lye (sodium hydroxide) into the cool elderflower tea until dissolved. Work in an area with good ventilation and be careful not to breathe in the fumes. Set the lye solution aside to cool for about 30 or 40 minutes or until the temperature drops to around 100 to 110°F (38 to 43°C).

Step 2: Prepare the Oils

Gently heat the coconut oil and cocoa butter on low heat until melted. When the solid oils are melted, take the pan off the heat and pour in the liquid oils. This helps cool down the melted oils while warming up the room temperature oils.

Step 3: Mixing

Pour the cooled lye solution into the warmed oils. Using a combination of hand stirring and an immersion blender (stick blender), stir the soap batter until it thickens and reaches trace.

Blend until the batter thickens into trace

Step 4: Add the Essential Oil

When the soap batter has thickened to the consistency of warm custard, stir in the essential oil(s) for scent.

Step 5: Pour in Mold

Pour the soap batter into your soap mold. Cover lightly with wax or freezer paper, then a towel or light blanket. Peek at the soap every so often; if it starts developing a crack, uncover and move to a cooler location.

Pour the soap into a silicone loaf mold immediately after it traces

Step 6: Cut & Cure

Keep the soap in the mold for 1 to 2 days, or until it’s easy to remove, then slice it into bars when it’s firm enough not to stick to your cutting tool. Cure on coated cooling racks or sheets of wax paper for about 4 weeks before using. The soap is safe to touch 48 hours after making it but it needs the extra time to allow the excess moisture to evaporate out. For full instructions on how to cure handmade soap head over here

  1. I make goat milk soap, but I want to use the elderflowers, is that possible? Can I make a tea out of the goat milk?
    Thanks,
    Jo

    1. Just to be clear about the elderflowers in this recipe — they will not scent the soap. You could infuse them into your goat milk beforehand if you wish to use them though.

  2. Hello. I followed the recipe, but even after three days in the mold my soap was quite soft. I managed to cut it, but it had this brie cheese texture, which felt wrong. It was getting stuck to the knife all the time. What could it be due? Thank you.

    1. Hi Dina, I expect that you didn’t bring the soap to a full trace before pouring it into the mold. Mix it a little longer next time so that the oils and lye get enough time to interact before pouring. Good luck :)

  3. Hey any replacement of elderflower tea? Because I didn’t get it in my areas..
    kindly reply me if any replacement is available..

  4. Hi Tanya

    I just wanted to say I am really enjoying your website and all the inspiring information and beautiful pictures! I am looking forward to trying the elderflower soap but will have to wait a while as we are opposite your seasons here in New Zealand!
    Thanks for sharing!

  5. can the water be replaced with frozen goats milk in ALL your recipes? wish you had a “print” button for your website recipes.
