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, unsweetened cocoa powder, and salt until evenly distributed.
03 - In a large mixing bowl, beat the softened unsalted butter, granulated sugar, and packed light brown sugar together using an electric mixer or whisk until the mixture is light and creamy.
04 - Pour in the whole milk, vanilla extract, and red food coloring into the butter-sugar mixture. Beat until the color is uniform and all liquids are fully incorporated.
05 - Gradually add the dry ingredient mixture to the wet ingredients, folding and mixing gently until just combined. Avoid overmixing to maintain a tender texture.
06 - Using a spatula, gently fold the white chocolate chips into the dough until evenly distributed throughout.
07 - Enjoy immediately at room temperature, or transfer to an airtight container and refrigerate for up to 5 days.
