Rainbow Sprinkle Bath Tub Cookies
Ingredients
20 – 30 drops FD&C Yellow #5*
3/4 cup Epsom Salt
1 cup Oatmeal, Fine
1/4 cup Whole Milk Powder
1/4 cup Honey Granules
1 cup Cornstarch
1 cup Baking Soda
1/2 cup Citric Acid
2 oz. Mango Butter
2 oz. Organic Virgin Coconut Cream Oil
1/2 oz. Easter Cookie Fragrance Oil*
1/2 Teaspoon Assorted or Solid Colored Jojoba Wax Beads*
Directions
Line a large baking sheet with wax paper or plastic wrap and set it aside. Pour Epsom Salt into a large mixing bowl and color generously with the FD&C Yellow #5 Dye. You’ll need about 20 to 30 drops to dye the salt bright yellow. Mix the salt thoroughly to make sure that it is evenly dyed. Next, add the Whole Milk Powder, Cornstarch, and Oatmeal, breaking up any clumps in the powders. Add the Honey Granules next. In a small heat proof container gently melt the Mango Butter and Organic Virgin Coconut Oil. You can either use a double boiler or a microwave to do this. If you use a microwave be sure to melt the oils in short 20 – 30 second bursts. Be careful not to overheat and damage the oils. When the oils are melted, allow them to cool for a few moments before adding the Easter Cookie Fragrance Oil to them. Next, add the Baking Soda and Citric Acid to the large mixing bowl. Mix the powders thoroughly then add the melted oil mixture, stirring constantly. After the oils and powders are mixed, wipe the mixing spoon clean and continue to knead the dough with your hands. This will make sure that all the ingredients are completely mixed. Using your hands, form small round balls out of the dough. Drop them onto the baking sheet and press them with your hands to form cookie shapes. Continue until all of the dough is used. This recipe will yield about 2 dozen 2 inch cookies. Allow the cookies to dry and harden for several hours before attempting to move or package them. The will harden completely when left overnight in a cool, dry place.
Usage and Packaging
Rainbow Sprinkle Bath Tub Cookies look adorable when packaged in our Small Cello Bags. Use a piece of ribbon or a twist tie to close each bag. To use the cookies, simply drop one or two in a warm bath. The cookies will fizz, melt, and disperse into the water.
*These ingredients contain synthetic components and can be left out if desired. Natural Herbs can be used to top the cookies, and Vanilla Absolute can be used to scent them. Leaving out the FD&C Dye will only alter the color slightly, so a substitute is not necessary.
Remember, you can purchase all the ingredients and packaging you’ll need to create around two dozen Rainbow Sprinkle Bath Cookies in our Body Care Craft Kit for just $20.00! Body Care Craft Kits or finished cookies make excellent, affordable holiday gifts. 
yummo!
They look good enough to eat!!
I’d love to try it.
Please let me know if you do try these out. I would LOVE to see some pictures of other people’s batches. I am totally bonkers for bath cookies.
I’m working on some Valentine projects and I think these would be great, along with some of your other ideas like the raspberry scrub. How do you think the cookies will take to color such as pink?
Thank you!!
These Cookies would make great Valentine’s Gifts! You could certainly color them pink using Red FD&C Liquid Dye. The color with the dye alone may be a bit subtle though. To intensify the color, try adding some Pink Glimmer or Red Heart Mica to the dry ingredients.
I really want to make these cookies, but I would like to know more about one of the ingredients. Is Virgin Coconut Cream Oil the same as Virgin Coconut Oil? If not, can I substitute for another oil or butter?
Your recipes look delightful and I can’t wait to try them out!
Hi Karen. Our Organic Virgin Coconut Cream Oil is a very high quality virgin coconut oil. You can certainly use any all-natural brand of virgin coconut oil for this recipe though. You could also substitute that oil with any vegetable oil or butter that remains solid at room temperature. I hope you have a great time making this recipe. Enjoy, and let us know how your batch turns out.
Made these cookies but they didn’t harden. This is the third day and they still crumble. Wanted them for a fair I’m doing tomorrow. Very disappointed. Followed recipe exactly but they didn’t get hard enough to package. Any suggestions as to what I can do with them now?
I’m really sorry that this recipe didn’t work out for you. Bath fizzies can sometimes be unpredictable because they are so sensitive to moisture. The humidity in the air can sometimes be enough to set them off, or soften them. Fizzies that include Butters or Oils can be especially tricky during warm weather, as the butters or oils might not want to harden or set.
If you’re looking for a way to salvage the ingredients, I’d suggest turning them into non-fizzing bath cookies. This can be done by crumbling them up, adding a little more Mango Butter, then pushing them into small molds. Silicone Ice Cube trays work really well for this. Pop the molds into the fridge for about an hour before un-molding them. If it’s still warm where you live, you might want to also add a pinch or two of Beeswax or Jojoba Esters to the additional Mango Butter to help them set up.
Thanks so much for trying out the recipe, and for letting me know how it went for you. I hope you can find a way to make use of the ingredients, and again, I’m sorry that it didn’t work out for you.
