These easy DIY is similar to how to make hand-milled soap. While it works best with cold process soap, it will also work with any soap you have on hand.

Keep reading for my easy shaving soap in a mug recipe. This hand milled or rebatch soap DIY instructs you on how to create personalized DIY Father’s Day gifts for Dad.

Rebatch Shaving Soap Recipe

To make this DIY shaving soap in a mug, you simply rebatch the shredded soap and mix it with other ingredients to create a new soap with additional or differing skin care properties. The final soap will look similar to hot process soap and have that rustic appearance. However, by mixing the existing soap with new ingredients, you can make it more conditioning for skin.


These are the ingredients you will need to recreate this easy, rebatched shaving soap recipe:

  • 4 oz. of soap or shredded soap base — I used a bar of my unscented Banana Oatmeal Soap
  • 3 Tablespoons milk
  • 5 drops fragrance oil, optional (approximately 2% of the soap recipe)

Supplies and Materials

These are the and materials you will need when learning how to make homemade shaving soap in a mug:

How to Make Shaving Soap in a Mug

Follow these simple steps to make this rebatch soap recipe:

1. Grate your bar of handmade soap or leftover soap slivers into a saucepan.

Your grated soap should look like the above photograph. There’s no need to grate it as fine as possible.

2. Stir in 3 Tablespoons of milk. Turn the eye on the stove to medium heat.

TIP: Alternately you may use distilled water to rebatch the soap. However, I think milk works best. Plus, the fats present in milk give the soap skin conditioning properties.

3. Stir the soap occasionally until fully melted.

4. Once melted, you can in your choice of essential oil or fragrance oil. Then mix well. Sandalwood is a great choice for a masculine scented essential oil as is a combination of cedar and sage essential oils.

TIP: Generally you’ll want to use about 1-2% of essential oil per your total soap weight or 2-5% in fragrance oils. But always refer to manufacturer guidelines on how much fragrance or essential oil should be used. I used a fragrance oil called Edward’s Temptation for this soap which is a fragrance blend of Bergamot, Rosemary, Moss, Sandalwood, Mint, and Amber.

5. Spoon the melted soap into your clean mug. Then allow the mixture to cool and harden. The soap is ready to be used as soon as it has hardened and all excess liquid has evaporated from the soap.

5. Now pair your mug of shaving soap with a shaving brush gift for Dad!

Alternately this method of soapmaking, which is commonly referred to as hand-milling or rebatching soap, can be used with any leftover handmade soap to create new soaps with a fragrance outside of a mug. In this instance, rather than pouring the soap into mugs, simply pour it into molds. Then remove the hand milled soap once it has hardened.

Note hand milled or rebatched soap will shrink slightly as the excess liquid evaporates. This makes them easier to remove from the molds. You can also wait for the melted soap to cool and roll the soap into balls as illustrated in this tutorial on making aloe vera soap balls.

Packaging your homemade soaps is then as easy as wrapping them with waxed paper and a ribbon! You can also explore other ways to package soap with this collection of soap packaging ideas.

Cold Process Shaving Soap Recipes

While these recipes for shaving soap don’t call for a mug, you can use one! Simply pour the cold process soap batter into individual mugs. Then allow to set up as usual. They will be ready to use after curing for 4 to 6 weeks. Alternately, you can also make these as homemade soap bars.

  • Glycerin Shaving Soap Recipe: This homemade cold process glycerin shaving soap recipe includes extra vegetable glycerin that’s added to the regular soapmaking oils during the soapmaking process. Typically this is usually only done for shaving soaps as the extra glycerin contributes to the bar’s humectant properties.

This glycerin shaving soap recipe simply expands on that.
