Soft and Chewy Peanut Butter Cookies

These are seriously the best peanut butter cookies I have ever made.  I used my mother in law's recipe and "tweaked it" a little by adding my new favorite cookie ingredient...maple syrup.  It makes the cookies so soft and chewy!!  Here it is:
cream together:
1 cup of butter at room temperature
1 cup creamy peanut butter
1 cup brown sugar
1/2 cup white sugar
1/3 cup maple syrup ( I use the "fake" off brand syrup-butter flavored)
Add:
2 eggs and beat well.
Add:
1 tsp vanilla
1 tsp baking powder
1 tsp baking soda
2 1/2 cups flour
Mix and roll into ping-pong or golf ball size balls and roll in white sugar. 
Score with a fork and bake on ungreased cookie sheet at 350 degrees for 10 minutes.
Enjoy!
