Preheat oven to 350° F
In a medium mixing bowl combine the flour, baking soda, and salt.
In a separate larger bowl combine the peanut butter, maple syrup, olive oil, and vanilla.
Pour the flour mixture over the peanut butter mixture and stir until barely combined (still a bit dusty looking).
Let sit for five minutes, give one more quick stir (just a stroke or two).
Drop by heaping tablespoonfuls onto parchment-lined baking sheets. Press down on each one gently with the back of a fork.
(** Note: This is a loose batter, so if you’re set on doing criss-crosses, go ahead and chill the batter for an hour or so before this step)
Bake for 10-11 minutes, keeping an eye on them so they don’t over bake, or they'll be dry.
Let cool for a few minutes before transferring to a cooling rack.
