Sweet grass and clary sage soap recipe

Sweet Grass and Clary Sage Soap (Kathy Miller) from Miller Soap

24 ounces coconut oil
24 ounces canola oil (can use peanut, corn or sweet almond oil)
36 ounces soybean oil
24 ounces cold water
12 ounces lye crystals

Temperatures: 110-120 degrees

Added at light trace:
1 ounce Sweet Grass FO from Sweet Cakes
1 ounce Clary Sage Essential Oil

This needed a little bottom heat like the Cocanolive batch so I raised the temperatures here. After adding the fragrance and essential oils, I stirred a bit longer and then poured most of the soap. To the remainder, I added a few shavings of teal green candle color that had been melted with a little bit of coconut oil. This was mixed in quickly and the green soap poured on top of the uncolored. I had intended to swirl it, but the soap got too thick on me and try as I might, this was as much swirl as I could get! It’s actually kind of interesting the way it turned out. If you want to recreate this look, you just have to let the soap get to the soft pudding stage before adding the second color and it will refuse to drop down and swirl with the rest of the soap in the pan! This is a little heavier on Clary smell at this point than Sweet Grass. You could probably up the Sweet Grass by another half an ounce, or drop the Clary to 1/2 an ounce. They seem fairly strong and I wouldn’t add more than that for my nose…but you might like POWERFUL smelling soap or need it to last for a long time in storage.

Why You’ll Love These Spooky Bath Bombs

Kid-safe ingredients – No creepy chemicals here
Great for gifting – Pop into mini cauldrons, treat bags, or mason jars
Smells like fall – Think pumpkin spice, candy corn, or sweet orange
Budget-friendly – Uses pantry staples and affordable citric acid
Easy to customize – Add spiders, glitter, glow-in-the-dark mica, or even a surprise toy

Ingredients

1 cup baking soda
1/2 cup citric acid
1/2 cup cornstarch
1/2 cup Epsom salt or fine sea salt
2 tsp sweet almond oil (or coconut oil)
1 tsp water or witch hazel in a spray bottle
10–15 drops essential oil (sweet orange, lavender, cinnamon, or candy-like blends)
Natural colorants or skin-safe mica powder (orange, purple, black, green)
Optional: eco glitter, mini plastic spiders or Halloween charms
Silicone molds or mini plastic cauldrons

How to Make Halloween Bath Bombs

1. Mix the Dry Ingredients

In a large mixing bowl, combine baking soda, citric acid, cornstarch, and Epsom salt. Whisk until it’s smooth and uniform—like a dusty spellbook.

2. Blend the Wet Ingredients

In a small bowl, mix your carrier oil and essential oils. Add your chosen colorant and glitter here too. If using black, go light—it can stain tubs if overdone.

3. Combine with Care

Slowly drizzle the wet mixture into the dry mix, whisking continuously. It should feel like damp sand. If it clumps when squeezed, you’re ready. Mist lightly with water or witch hazel if too dry.

4. Add Hidden Surprises

Press a small plastic spider, glow cube, or toy into the center for a trick-or-treat effect!

5. Mold It Up

Spoon the mixture into your molds, pressing firmly. Let them dry at least 24 hours before popping out.

Spooky Variations to Try

Spider Surprise

Hide a plastic spider inside and use black mica for a creepy crawl effect.

Pumpkin Spice Delight

Add a dash of cinnamon and orange essential oil with orange coloring.

Glow-in-the-Dark Witch Bombs

Use glow mica and store under light for a fun bathroom glow!

Boo Bombs for Kids

Make ghost-shaped fizzies using a silicone mold and sweet vanilla oil.

Packaging Ideas for Gifting

Wrap in cellophane with twine and a tag: “Drop in warm water and summon a spooky soak!”
Nestle in mini cauldrons from the dollar store
Use kraft boxes lined with Halloween tissue paper for classy spooky gifting
Add a punny printable tag like “You’re the bomb!” or “Witch, please!”

Tips & Tricks

Don’t over-wet your mixture—it can fizz prematurely.
Use gloves to avoid stained fingers.
Let kids help with colors and pressing (just maybe keep the glitter far away unless it’s a full moon).

Why These Are Better Than Candy

Let’s be honest—October sugar overload is real. These bath bombs are a charming alternative that still feel like a treat. Plus, they turn your bathroom into a spa and a mad scientist lab.

Whether you’re making them for your kids’ school party, teen Halloween sleepovers, or your own pumpkin-scented peace and quiet after bedtime chaos, these DIY bath bombs are a crafty way to keep Halloween fun—and fizzy.
