1 1/4 c. sifted all-purpose flour
1/4 tsp. baking soda
1/4 tsp. salt
1/2 c. butter, butter or shortening
1/2 tsp. vanilla
1/2 c. granulated sugar
1/2 c. brown sugar
1/2 c. peanut butter
1 egg, unbeaten

Preheat oven to 375 degrees. Sift the flour once, then measure it. Measure the soda and salt. Sift them with the flour onto waxed paper and set aside.

Measure the fat into mixing bowl. (It should be soft). Measure the vanilla and mix it well with the fat. Mixing can be done with a spoon or an electric mixer.

Measure the granulated sugar and mix it well with the fat. Measure and add the brown sugar. Mix until batter is smooth, creamy and fluffy. Measure the peanut butter. Add it to the batter, mix until well blended.

Break egg into small bowl. Add it to batter and mix until well blended. Add about 1/3 cup of the flour mixture and mix well. Add another 1/3 of flour mixture and mix well. Add remaining flour mixture and mix well. The dough should be smooth.

Lift dough by teaspoon and shape into balls about size of a walnut. Place the balls about 2 inches apart on an ungreased cookie sheet. Press with the back of a fork to flatten and mark each ball. Press evenly to make each cookie about 1/4 inch thick. If you dip the fork in flour, the dough will not stick to it. Bake until browned about 12-15 minutes.
