This is one of my all-time favorite cookies. Soft, thick and just a little chewy, they make the perfect "dunker" for after dinner tea or coffee or with a glass of ice cold milk for a special treat. If you like soft peanut butter cookies, these are for you. Just the perfect balance of sweet and salty.
Preheat oven to 350 degrees. Line a baking sheet with parchment paper.
Cream together butter and peanut butter until well mixed.
Add brown sugar and white sugar and mix on medium for 2 minutes until light and fluffy. Add salt, soda, baking powder, vanilla and egg. Mix until well blended.
Slowly add flour until just mixed and dough is a uniform color.
Roll into 1 1/2" balls. (Can roll in sugar at this point, but I never do.)
Transfer to prepared baking sheet. (12 to a large cookie sheet.) With a large glass or the palm of your hand, flatten just a little bit... not too much! You want them to stay thick and chunky! =)
Bake for 7-8 minutes until they just start to brown. Don't over bake. Cool on wire racks topped with paper toweling to cool.
***To keep cookies like these soft for several days, (...if there's any left!) place a piece of white sandwich bread in with the cookies in a large ziplock bag the next day. When the bread starts to become firm, replace with a new piece.
