In a microwave safe bowl, microwave your flour for 60-90 seconds, stirring halfway through. Set aside to cool completely.
In a medium mixing bowl, cream together softened butter and brown sugar. Once smooth, mix in the milk and vanilla extract.
Sprinkle in the heat-treated flour and mix to form a dough. Fold in mini chocolate chips.
Place the dough in the freezer for 10 minutes to make it less sticky, then working one by one, roll the dough into ½ inch balls.
Place the cookie dough balls on a baking sheet lined with parchment paper or a silicone mat.
Working one by one, sandwich each cookie dough ball inbetween 2 pretzels and place back on the prepared baking sheet.
Combine your semi-sweet chocolate and vegetable oil in a microwave safe bowl and microwave in 30 second intervals until melted and smooth.
Dip each cookie dough stuffed pretzel halfway into the melted chocolate, then return to the prepared baking sheet.
Transfer to the fridge (or freezer) to let the chocolate harden before serving.
