Learn how to make a coffee bath bomb recipe. Coffee has several benefits for your skin, and using it in a bath bomb gives a delectable scent that any coffee lover will enjoy.

Coffee Bath Bomb Recipe

Imagine sinking into a warm bath, the room enveloped in the rich, earthy aroma of freshly brewed coffee.

A coffee bath bomb is more than just a nod to your morning cup — it's a luxurious treat that energizes your senses while pampering your skin.

It's the perfect intersection of relaxation and revitalization, offering a spa-like experience from the comfort of your own home.

Benefits of Coffee for Skin and Senses

Coffee is a natural powerhouse. Packed with antioxidants and anti-inflammatory compounds, it helps rejuvenate tired skin, soothe irritations, and boost your mood with its familiar, invigorating scent.

In skincare, coffee’s exfoliating texture and circulation-boosting properties make it a standout ingredient for those seeking a vibrant, healthy glow.

Exfoliation and Circulation Boosting

Coffee grounds provide a natural, non-abrasive way to slough off dead skin cells, revealing a smoother, more radiant complexion beneath.

As you massage the bomb’s particles over your skin, they stimulate blood flow, invigorating tired muscles and encouraging a healthy, rosy glow.

Natural Anti-Inflammatory Properties

Caffeine’s natural ability to constrict blood vessels makes it a formidable ally against inflammation. A coffee bath bomb can help calm puffiness, reduce redness, and even soothe conditions like eczema and psoriasis. It’s a gentle yet potent solution for achieving balanced, resilient skin.

Awakening Aromatherapy Effects

Few scents are as universally uplifting as the rich, deep aroma of coffee. It energizes the mind, sharpens focus, and promotes a sense of well-being.

A coffee scented bath can lift you out of a mental fog and prepare you to face the day with clarity and vigor.

Ingredients for a Coffee Bath Bomb

Coffee Grounds: Fresh vs. Used

When crafting your bath bomb, fresh grounds offer a stronger fragrance and a more potent exfoliating texture.

However, repurposed (dried) used grounds are an eco-friendly alternative that still deliver gentle exfoliation and a softer scent, perfect for those who prefer a subtler experience.

If you reuse coffee grounds, make sure they are completely dry before using in bath and body products.

Carrier Oils

I used coconut oil for these bath bombs because it's solid at room temperature, helping the bath bombs keep their shape.

Picking the Perfect Essential Oils for Scent

While coffee has a delightful aroma on its own, layering it with complementary essential oils — like vanilla, or even a dash of orange — can create a signature scent profile.

I just used a coffee essential oil, but you can also use vanilla essential oil. Coffee also pairs well with copaiba or Peru balsam if you have those oils.

Simply Earth sells a Vanilla Latte set with Coffee essential oil and Peru Balsam essential oils.

The Importance of Baking Soda and Citric Acid

These two ingredients are the engines behind your bath bomb’s fizz. Baking soda softens water and soothes the skin, while citric acid provides the effervescent magic that makes bath bombs so fun to use.

Step-by-Step Coffee Bath Bomb Recipe

Step #1

In a large mixing bowl, add the baking soda, citric acid, arrowroot powder and dead sea salts. Whisk dry ingredients together. You can sift dry ingredients to get rid of any clumps or hard pieces.

Step #2

Add the coconut oil. The coconut oil binds all the ingredients together, so your bath bombs have stability and don’t crumble when you touch them. Add the polysorbate 80. This helps the coconut oil disperse more evenly in your bath water, makes the bath bombs bubbly.

Step #3

Mix wet ingredients in well. You may need to use your hands to break down any lumps and make sure everything is mixed in. The mixture is perfect when it holds together when you press it into your hands and feels like wet sand.

Step #4

Add in 1 tablespoon ground coffee and the coffee essential oil. Mix well.

Step #5

Add a pinch of the ground coffee to one side of a bath bomb mold. Gently add the bath bomb mixture to each side of the bath bomb mold until slightly overflowing.

Step #6

Over the smaller, empty bowl, press molds together and gently but firmly grind to remove any excess mixture. Gently tap mold to release the bombs. Allow to dry a minimum of 24 hours. If your climate is wet or cold, allow an additional 24 hours.

My rule of thumb is that when it is hard to the touch, they are ready for the tub! Store in an airtight container for up to 6 months until ready for use.

Variations to Customize Your Coffee Bath Bomb

Here's how to customize your coffee bath bombs:

A spoonful of cocoa powder turns your bath bomb into a delicious mocha delight, adding an extra layer of aroma and a luxurious brown tint to your soak.
Add a few drops of vanilla essential oil enhances the cozy factor, creating a warm, inviting fragrance that feels like a comforting hug on a chilly day.
Biodegradable glitter or dried rose petals can give your coffee bath bombs fun look. Just be sure any additions are bath-safe and skin-friendly.
Make coffee infused oil to use for more coffee skin benefits.

Troubleshooting Common Bath Bomb Problems

If your bath bomb is too dry, it won't hold its shape. Remedy this by adding a few more spritzes of liquid and mixing gently to the right consistency.
Over-wetting can cause premature fizzing and expansion. Use just enough liquid so the dry ingredients hold their shape, applied gradually, and press your molds tightly to prevent misshapen results.
Seal your finished bath bombs in an airtight container immediately after drying. Proper storage helps preserve the coffee oils and keeps the scent vibrant until bath time.

Store bath bombs in a cool, dry place away from sunlight. Moisture is their enemy; silica gel packets or airtight tins can help absorb any lingering humidity.
