Microwave the flour in 20 second intervals until it reaches 165℉ degrees, about 40-60 seconds. Alternatively, you can spread the flour on a baking sheet and bake the flour in a 350 ℉ degree oven or 3-5 minutes. Wisk or sift to remove any lumps and let cool.
Using a standing mixer, a large bowl with a hand held mixer, or a spatula cream the butter, granulated sugar sugar, brown sugar, and peanut butter on medium speed until light and fluffy.
Add in flour, vanilla, salt. Add in milk 1 tablespoon at a time until desired consistency is reached.
Gently fold in any mix ins using a spatula or spoon. Enjoy!
