Best peanut butter powder for ermine frosting?

I want to make peanut butter ermine and after doing some research feel the safest method is powdered peanut butter rather than creamy/natural peanut butter. I have never had powdered peanut butter and have found a lot of options, PB2 original and PB2 Pure are the main ones I was between. Can anyone recommend the best peanut butter powder to use? Will it taste like normal peanut butter? I am making for a family members birthday and don’t want it to taste like weird fake peanut butter lol. Thanks!
