Place coconut oil and mango butter in a pot and warm over low heat until melted. You may also use a double-boiler, if desired.Once melted, allow to cool briefly. Add the oil and soap. Stir to combine.If mixture is cool enough, pour into a mixing bowl. If not, let cool until close to room temperature, before transferring to a bowl. Place in the fridge until completely cool.Allow to harden. This could take up to an hour.Once hard, remove bowl from fridge. If mixture is too firm to beat with an electric mixer, allow to soften a little.Use a hand mixer to whip mixture for at least two minutes. If mixture is not fluffy after two minutes, whip for another minute.It will resemble whipped frosting.It's tempting to lick the beaters!Cream will vary in volume depending on how long it is whipped.Once sufficiently whipped, transfer shaving cream to a container (a 4 to 6 ounce container should work) and close with lid.
