**Prepare the Flour:** Preheat your oven to 350°F. Spread the flour on a baking sheet lined with parchment paper. Bake for 10 minutes to kill any bacteria. Let it cool completely.
**Mix the Dough:** In a large bowl, cream together the softened butter, granulated sugar, and brown sugar with an electric mixer until light and fluffy. Mix in the vanilla extract.
**Add Dry Ingredients:** Add the salt and the cooled flour to the butter mixture, mixing until combined.
**Incorporate Milk:** Gradually mix in the milk until the dough comes together.
**Add Chocolate Chips:** Fold in the mini chocolate chips with a rubber spatula.
**Form the Bites:** Use a small, 1-tablespoon cookie scoop to portion the dough. Roll each portion into a ball and place on a parchment-lined baking sheet. Chill the dough balls in the fridge for 15 minutes.
