Heat-Treat the Flour: Spread the flour on a baking sheet and bake at 350°F (175°C) for 5 minutes, or microwave in 30-second intervals until the flour reaches 165°F (74°C). This step ensures the flour is safe to eat.
Mix the Dough: In a small bowl, cream together the softened butter and brown sugar until smooth.
Stir in the vanilla extract.
Add the heat-treated flour and a pinch of salt to the butter mixture. Stir until combined.
Stir in the milk until the dough reaches your desired consistency.
Fold in the chocolate chips.
Enjoy your edible cookie dough immediately, or chill it in the refrigerator for a firmer texture.
