These are easy, fast and delicious. My oldest son loved them when he was a child and insisted they were brownies. I added peanut butter and left the nuts off to make them more kid-friendly.
1 cup softened butter ( not melted)
1 cup brown sugar
1/4 cup peanut butter
2 level cups white flour, 1/4 tsp. salt
2 cups semi sweet chocolate chips
Preheat oven to 350 degrees
Mix butter and brown sugar until fluffy, add egg and peanut butter, mix. Add flour and salt, beat until smooth. Spread in ungreased 9X13 baking pan. Bake for 15 to 20 minutes or until golden brown and done. Remove from oven and sprinkle chocolate chips on top. Put pan back in oven for a minute. Remove, spread chocolate evenly over crust. Sprinkle with nuts if desired.
