I too have always wanted to make cup cakes. I found a whipped soap on you tube and followed the recipe. It is cp but was very easy.
I use M&P for the base of the cup cake, then used the whipped soap recipe below.
They turned out as well as I could expect for the 1st time trying. My 16 yr old niece helped and had a lot of fun.
Whipped Soap
Castor oil 0.40 oz. CO 2.70 oz
PO 2.70 oz. Lard 2.70 oz.
Soy oil 1.5 oz.
Lye 1.428 oz.
Water 3.8 oz.
DO NOT MELT OILS- Mix (solid) CO, PO, Lard. Whip with hand mixer until it fluffs like meringue.
SLOWLY add castor, and soy, whip again **Peaks will soften a bit**
Then add VERY COLD lye/water (put in fridge). ADD VERY SLOWLY to oils WHILE whipping with mixer.
Add F/O, and mix it with SPATULA.
Then add color mica (full powder) **DO NOT MIX COLOR WITH OIL 1ST** mix color into whipped soap using mixer again. **Add a little more color than normal as the color will fade in whipped soap to pastel color** (USE A COFFEE STIRRING STICK to measure color)
LET STAND for 2-3 minutes.
Add soap into bag, tie off the tip with twist tie so soap won’t seep thru the tip. Once bag is full you can make all kinds of designs.
THIS WORKS GREAT AS A TOPPER FOR CUP CAKE SOAP!!!!
