Cupcake Bath Bombs
Try not to eat these delicious-looking cupcakes, because they are made of soap! These cute cupcakes fizz when dropped in the bath. Make a whole batch for gift-giving occasions with this tutorial from Little Birdie Secrets.
Materials for bath bomb:
- 2 c. baking soda
- 1 c. citric acid (We found this in the bulk section at a local health food store)
- 1 Tbsp. oil of your choice (We like almond oil, but grapeseed oil or even olive oil would work)
- 5 drops fragrance/essential oil
- 3-5 drops coloring (You can use food coloring, but it may fade quickly and even leave a ring around your bathtub. We used a special oil for bath products we found on Brambleberry.com.)
- 1 tsp. Bentonite clay (optional--this just makes them harder; we found it here, too.)
- 1 tsp. to 1 Tbsp. Sodium Lauryl Sulfate (optional--this makes your bombs lather up, and we also found it here.)
- Witch hazel (poured into a spray bottle)
- Paper cupcake liners
- Silicone cupcake molds
Materials for icing:
- 3 Tbsp. meringue powder (we like Wilton's) or powdered egg whites (you can use real egg whites or egg white substitute, but we didn't have very good luck with them)
- 1 lb. (measured by weight) powdered sugar
- 1/4 tsp. Cream of Tartar
- 5-6 Tbsp. warm water
- Few drops of color
- Glass bowl
- Hand mixer
- Optional: Few drops of fragrance
- Prepare your molds by placing a cupcake liner inside the silicone cupcake mold. It won't fit perfectly--just shove it in.
- Place all the dry ingredients in a large bowl and gently mix. Be careful not to inhale it!
- Add fragrance to the dry mixture. Measure out the oil and place a few drops of color to it. Add it to the dry mixture. Gently mix.
- While kneading the mixture with one hand, begin spraying the mix with the witch hazel. (We did this as a team, but one person can do it alone.) Be careful not to get the mixture too wet--the moisture will activate the citric acid and your bath bomb will be ruined. Continue to slowly spritz the mixture with witch hazel and squish it in your hands until it has the consistency of crumbly pie dough.
- Quickly pack the mixture into your liners inside the silicone molds. You want it to be packed in tight. Allow the mixture to set in the silicone mold for at least 5-10 minutes before removing. Now let's add some frosting to these bad boys.
- Make your frosting- Mix meringue powder into warm water first in a GLASS bowl. Add cream of tartar and powdered sugar. Start beating on high. If your mixture feels like stiff cookie dough at this point, add another tablespoon of water. Beat for 7-9 minutes. Frosting is done when it forms stiff peaks and is thick and fluffy.
- Add color and fragrance and beat until well mixed (one minute or less).
Note: If you decide to add baking soda (for fizziness) and sodium lauryl sulfate (for lather), you will want to increase your water to about 6-7 Tbsp. Add them with the color and fragrance.
- Spoon frosting into a disposable cake frosting bag with the cake decorating tip of your choice.
- Frost your cupcake bath bombs however you like. Allow bath bombs to sit overnight to harden before packaging. Be sure to let your children, husband, or dog know these are NOT EDIBLE!
- Package them in cellophane bags with pretty ribbons and tags for the perfect gift!
