Okay I make this for my son-regular waffle mix (straight from the box) then add about 2 tablespoons melted PB (mic it for about 20 seconds until metly) and voila-now I also add sometimes a couple of chocolate chips too (he's little)

Comes out tasting like one of those peanut butter blossom cookies.
If you don't melt the PB it won't blend with the batter
