Notes
Notes -
I use Kraft smooth peanut butter and Hershey's special dark cocoa powder.
This loaf is easier to cut when it's cooled.
Substitutions - Use chunky peanut butter instead of smooth. Add chocolate chips or chopped peanuts if you like.Storage - Keep at room temperature for about three days. I wrap mine in plastic wrap. Slice and freeze any leftovers.
