Preheat oven to 350 degrees. Line 2 baking sheets with parchment paper. In a medium-sized bowl, cream together sugars, egg, vanilla, baking soda, salt, honey, water and PB2, beating until smooth. Add flour, beating until mixture is well combined. Dough will be very sticky. Drop Tbsp-sized balls onto prepped baking sheets. Press top of each cookie with a fork to make parallel lines, flattening cookies to about 1/3 to 1/2 inch thick. Bake cookies for 10 minutes, reversing pans midway through (top to bottom, bottom to top). Remove from oven, and transfer to a rack to cool.
*Making these tonight for the kids... I will probably sneak one or two in:) I will let you know how they turn out!
