1 c. plus 2 tbsp. all-purpose flour
1/3 c. granulated or firmly packed light or dark brown sugar
1 tbsp. double acting baking powder
1 c. skim milk
1/3 c. less 1 tsp. chunky peanut butter
1/4 c. butter
1 egg
2 tsp. vanilla extract

Spray 9 x 5 x 3 inch loaf pan with nonstick cooking spray; set aside. On paper plate or sheet of wax paper combine dry ingredients; set aside. Preheat oven to 350 degrees. In medium bowl, using a wire whisk or fork, combine remaining ingredients, beating until egg is blended (peanut butter and butter will be lumpy); stir in dry ingredients, stirring just until moistened. Pour into sprayed pan and bake for 45-50 minutes (until loaf is golden and a cake tester inserted in center comes out dry). Set loaf in pan on wire rack for 5 minutes to cool slightly, then invert onto rack, remove pan, and let cool completely. Cut into 12 equal slices.
