cannabutter from possible male plant.

i am a first time grower with one plant. if this plant turns out to be male, i would like to make cannabutter with it. would anyone be able to provide simple, step-by-step instructions on how to make the butter? most of the threads that i have read on this topic are full of opinion, contradiction, and just plain confusing.

just a simple recipe, that is all i need.

thanks,
