This is a picture of a coffee soap I made with 3x brewed coffee and NG Cappuccino fragrance oil. I expected there would be a color difference between the outside and inside, but I didn't expect it to be so drastic. The fragrance is amazing!
Oh, definitely. The vanilla content of this fragrance is through the roof. I was just surprised because the batter was darker than the inside of the soap was. In fact this is what they look like less than 12 hours later.
