Classic Peanut Butter Cookies

1 cup butter
1 cup granulated sugar
1 cup brown sugar
2 large eggs
1 cup peanut butter
3 cups all purpose flour
2 tsp. baking soda
1/4 tsp. salt

Method:
Cream butter and sugars in large bowl until light and fluffy.  Add eggs one at a time, blending well after each addition.  Thouroughly incorporate peanut butter.
 
In seperate bowl, combine flour, baking soda and salt.  Mix well, and add to butter and sugars.  Stir until *just* combined.  Do not overmix!
 
Scoop onto parchment lined cookies sheets (if you have it; otherwise use non-stick sheets, or as a final resort, a lightly buttered sheet).  Flatten with tool of your choice: a fork, the bottom of a pretty bevelled glass, or the palm of your hand!

Bake at 275 C for 10 minutes, or until the bottoms are lightly browned and the top is "set".  Never trust your cookies to a 350 degree celius oven!  Ever!  Most home ovens run 50 degrees hotter than the dial temperature.  It's better to bake them a little longer than to risk burning/overbaking.  Transfer to wire racks to cool, brew a strong cup of coffee, or pour a glass of milk and enjoy!  Oh, and sharing with loved ones makes them taste even better!
