Very good. I did not have a problem with the frosting being greasy. As for substitutions, I softened both the peanut butter and butter and the butter in the microwave before mixing. This eliminated the need for any milk. I also used just a little more peanut butter than the recipe calls for and sifted through the confectioners sugar while adding it to make the frosting extra smooth. I served it on top of mini brownies and it was a hit! Will definitely use again!
