Here is a recipe for chewy brownies, they are great! Blend peanut butter and butter until smooth. Gradually add sugars; beat until fluffy and smooth. Add eggs, one at a time, beating after each. Add sifted flour and salt and mix well. Stir in chocolate chips and vanilla. Spread in buttered 9" square pan. Bake at 350 degrees for 30-35 minutes, or till nicely browned in center (darker brown around edges). Cool in pan on cooling rack. Cut into squares.
