Tips to Make this Coffee Bath Bomb Recipe
- Never food coloring in bath bombs, as it can stain skin and tubs and showers. If you want to color this, please use mica powder or soap colorants only.
- Mold this recipe in any flat-backed design so they will be safe for use as coffee shower fizzies, too. I love using the extra mix for this and you can use adorable silicone pans with fun shapes.
- If this is your first set of DIY bath bombs, see this article on trouble-shooting bath bombs and shower fizzies.
- Let the espresso bath bombs dry for at least 24 hours to get the most fizz, and 36 hours if you’re in a high humidity area or it is raining.
- To keep your bath bombs at their “top fizz” potential, store them in an air-tight container in your bathroom.

Coffee Bath Bombs
I'm not kidding, you take one bath with these invigorating coffee bath bombs and you'll be addicted. Such an easy coffee bath bomb recipe, it's ok to feed the obsession.
Materials
- 1 cup baking soda
- 1/2 cup citric acid
- 1/2 cup corn starch
- 1/4 cup Epsom salts
- 2-3 tablespoons freshly ground coffee (I used a very dark roast and a fine setting to get the smallest grains possible)
- 1 tablespoon oil (I used almond but you can use any long-lasting oil)
- 1/2 to 1 tablespoon water (divided)
- optional, 3-4 coffee beans per bath bomb for decoration
Tools
- large metal bowl
- 2 smaller bowls
- whisk
- spoon
- medium-sized bath bomb molds (we use these from Amazon and LOVE them)
- optional, spray bottle
Instructions
- Mix dry ingredients and whisk to until there are no clumps.
- Divide the mix into two equal parts and add the coffee grounds to one. Mix well. In the other smaller bowl, mix the wet ingredients.
- Slowly add 1/2 of the wet mixture to one of the dry mixes. You can add the wet ingredient to a spray bottle and add the moisture in increments to avoid over-saturating the dry mix and activating it.
- Stir the wet and dry mix until you have a consistency which is barely damp but, when pressed into your hand, will retain its shape. Repeat with the other dry mix and remaining 1/2 of the wet mixture.
- Once both mixes are ready, add 3-4 coffee beans into one side of a mold. Add the white portion of the mix to the mold with the coffee beans, pressing firmly and slightly overpacking.
- Press the coffee mix into the other side of the mold, slightly overpacking as well. Press the two sides of the mold together and let the bath bombs sit for a few hours. With this recipe, I left the molds overnight because I was unsure how the coffee would be incorporated. It worked perfectly.
- Pop the bath bombs out of the molds and store in an air-tight container.
