Peanut Butter Cookies

My 4 year old son requested peanut butter cookies the other day.  The recipe I have always used calls for shortening, but there wasn't any in the house.  I improvised with a slightly different version, and we were very pleased with the results.  The cookies were delicious, not overly crispy, and held up well for packing in school lunches even days later.  Here is the recipe -

Peanut Butter Cookies
1 c. butter softened
1 c. peanut creamy peanut butter
1 c. sugar
1 c. brown sugar
2 eggs
2 1/2 c. all purpose flour
1 tsp. baking powder
1 1/2 tsp baking soda
1/2 tsp. salt

1.  Mix the butter, peanut butter, sugar, and brown sugar until well creamed.
2.  Add the eggs and continue to beat.
3.  Measure and stir together the flour, baking powder, baking soda, and salt in a separate bowl.
4.  Add the dry ingredients to the butter mixture in small amounts continuing to mix.
5.  Refrigerate the batter for 30 minutes or until you can roll the dough into balls without the dough being too sticky.
6.  Roll the dough into 1 inch balls and space 2 inches apart on an ungreased cookie sheet.
7.  Use a fork to flatten each ball. 
8.  Bake at 375 degrees F for about 11 minutes or until the cookies begin to just brown at the edge.
