Cream together 3/4 cup butter, 1/2 cup peanut butter, 1 cup brown sugar, & 1/2 cup sugar until well blended.

Add 2 eggs and mix again. Stir in 1/4 tsp salt and 1/2 tsp baking powder. Scrape the sides of the bowl if necessary. Add 3 cups of flour. If you are going to wait to bake these cookies -- STOP here. Even if the dough is sticky. The flour will continue to absorb the moisture in the dough as it sits.

If you are going to bake right away -- continue adding flour 1/4 cup at a time until the dough pulls away from the sides of the bowl. Knead the dough together gently before rolling out. Bake at 350F for 7 minutes or until the center of the cookies look "dry."
