I got this recipe from Jean my co-worker. She said she found the recipe in the Amish column in the Post Bulletin (Rochester, MN newspaper). These bars are thicker than your standard bars and each bite is packed with a fantastic peanut butter flavor. They will not disappoint.
1 C. creamy peanut butter
2/3 C. butter, softened
1 1/2 C. sugar
1 1/2 C. brown sugar
4 eggs
4 tsp. vanilla
2 C. flour
2 tsp. baking powder
12 oz. chocolate chips
1/2 tsp. salt
Preheat oven to 325 degrees and grease 9 x 13″ pan. Cream peanut butter, butter, and sugars until smooth. Add eggs and vanilla. Mix til smooth. Add flour, baking powder, salt. Spoon into greased pan. Sprinkle with chocolate chips. Bake 5 minutes. Using a butter knife, swirl melted chips through the dough. Bake 40 more minutes until knife inserted in center comes out clean (some chocolate may stick to the knife). Cool one hour. Cut.
