Spread the all-purpose flour on a baking sheet and bake for 8 minutes, stirring once halfway through.
Allow heat-treated flour to cool completely before proceeding with the rest of the recipe.
In a medium-sized bowl, beat together the peanut butter and sugars until light and fluffy, about 2 minutes.
Beat in the milk and vanilla extract until well-combined.
Whisk together the flour and salt and then add to the batter and beat until completely incorporated and no dry streaks remain.
Add peanut butter chips, as desired, and then refrigerate until ready to serve.
