Bath bombs shaped like cupcakes and topped with piped frosting. A fun handmade gift.
What You’ll Need
Cupcake base
- 4 oz citric acid
- 8 oz baking soda
- 1 oz SLS (or bentonite clay for a harder bomb)
- 0.25 oz Caramel Sundae fragrance oil
- 5 drops La Bomb colorant
- Witch hazel in a spray bottle
Frosting
- 3 tablespoons meringue powder (or powdered egg whites)
- 1 lb powdered sugar by weight
- 5 tablespoons warm water
- 1/4 tsp cream of tartar
Equipment
- mixing bowl
- stand mixer
Directions
- Mix the citric acid and baking soda, breaking up any lumps.
- Mix in the SLS or clay, then the fragrance oil and colorant.
- If it doesn’t hold together like damp sand, spritz it with witch hazel and mix until it does. Pack it firmly into lined cupcake molds and let them dry.
- For the frosting, stir the meringue powder into the warm water, then add the cream of tartar and powdered sugar.
- Whip on medium speed 4 to 7 minutes, until it holds stiff peaks, and pipe it onto the dry bath bombs. Let the frosting harden overnight.
Notes
Drop one into a warm bath. Store them dry and airtight. Safety: wear a dust mask when mixing SLS and citric acid. They look like real cupcakes, so label them and keep them away from small children.
