PB2 or Peanut Butter: when to add?

Hey everyone! I just started the brewing process and since it is colder, I wanted to make a peanut butter stout but I had a quick question.

I am using a Oatmeal Stout 1 Gallon Craft Beer Brewing Kit (from BrewDemon) and was wondering at what stepI should add the peanut butter (probably PB2) and maybe banana to the recipe.

Can anyone help?

I am not going to be much help, but it sounds pretty good.  Looking forward to hearing how the end result tastes.

You’d be better off brewing a larger batch considering how much stuff you want to add.

I changed your subject topic to something that will hopefully get more hits. Hope that’s ok.
