01 - Spread the flour evenly across a baking sheet and bake at 350°F for 5 minutes to eliminate any harmful bacteria. Allow to cool completely before using.
02 - In a medium bowl, whisk together the heat-treated flour, cocoa powder, and salt until uniformly blended.
03 - In a large bowl, beat the softened butter, granulated sugar, and brown sugar together until the mixture is light and creamy.
04 - Add the milk, vanilla extract, and red food coloring to the butter mixture. Beat until fully incorporated and the color is even throughout.
05 - Gradually add the dry ingredient mixture to the wet ingredients, mixing until just combined. Avoid overmixing to keep the dough tender.
06 - Gently fold in the white chocolate chips using a spatula, distributing them evenly throughout the dough.
