The tutorial and recipe you’ve all been waiting for … Oatmeal Stout scented cold process made with real Oatmeal Stout Beer. Can it be? It’s true and it’s made with real oatmeal too!
Note: If you have never made cold process soap before, I strongly suggest getting a couple of basic recipes under your belt before diving in…working with beer is definitely an advanced technique. Check out Soap Queen TV on Cold Process if you want to get started with cold process. It’s a 4 part series that will take you through the basics (and be sure to watch the episode on Lye Safety). If you’re a book worm, Bramble Berry also has some helpful reading on the cold process

PREP: The first step to a successful beer batch (in my opinion) is boiling flat beer. Let your beer sit open for 24 hours to get rid of the fizz then boil it for about 5 minutes to cook out all of the alcohol. The beer really ‘poofs’ up during this boiling phase so don’t leave it unattended. Also, be sure to line your wooden mold with freezer paper, shiny side up.
ONE: Measure out your lye (by weight) and beer (by volume) and slowly add the lye to the beer in 3 batches (pour a little lye and stir- repeat 2 more times). Repeat until the lye is completely added and stir until the lye is dissolved. Let the lye mixture cool to about 130 degrees.
TWO: Melt and measure the Olive Oil, Coconut Oil, Palm Kernel Flakes and Palm Oil. Then stir in the Shea Butter (until liquid). Let the oils cool to 130 degrees.
THREE: Slowly pour the lye mixture into the melted oils and mix with your stick blender for about 30 seconds.
FOUR: Separate your soap batter in half. It does not have to be exact but try to eyeball it so it’s equally separated.
FIVE: Add a heaping table spoon of Titanium Dioxide to the one half of the batch to lighten it up and mix with the stick blender. Then add 1.5 tablespoons of long-cook ground oatmeal to the mixture and stick blend.
SIX: Hand stir in 2 ounces of Oatmeal Stout Fragrance Oil and pour the soap into the mold.
OPTIONAL: I dusted a vein of Super Pearly White Mica. This is an optional step. I couldn’t see it as much as I wanted in the final, cut soap.
SEVEN: To your other half of soap batter, add the rest of your Oatmeal Stout Fragrance Oil (2.1 ounces). Hand mix the fragrance in and pour the second layer.
TIP: To make sure the top layer of soap doesn’t penetrate the bottom layer of soap, pour the soap onto a spatula so it drips slowly into the mold.
EIGHT: Press your dividers down into the mold and sprinkle on some whole oats on the top for decoration. Pop the lid on and insulate with a towel to keep the temperature up. It will help with a lovely gel phase and also prevent soda ash. Once the soap hardens up, carefully unmold the soap and let it cure for 4-6 weeks.
