Soft, chewy peanut butter cookies rolled in sugar and topped with a Hershey kiss. These cookies should be a little crisp on the outside and soft and chewy within.
In a medium bowl, whisk together flour, soda, powder, and salt. Set aside.
In a large bowl cream together butter, granulated sugar and brown sugar until light and fluffy; add peanut butter, beat until incorporated; add egg and vanilla, beat until incorporated. You can beat with a hand mixer on medium or a wooden spoon.
Add the flour in 3 additions, mixing on low speed between each one.
Shape dough into 2-inch balls and roll in granulated sugar. Place 2 inches apart on an ungreased, unlined baking sheet. Bake 8 minutes or until the edges just begin to crack but there are no deep crevices in the center. Immediately press a Kiss in the center of each cookie and remove to a wire rack to cool.
Store in an airtight container. They are best eaten within 4 days.
