01 - Preheat oven to 350°F. Spread the all-purpose flour evenly across a rimmed baking sheet and bake for 5 minutes to eliminate any harmful bacteria. Allow the flour to cool completely before proceeding.
02 - In a large mixing bowl, beat the softened unsalted butter, granulated sugar, and packed light brown sugar together using a hand mixer or stand mixer until light and fluffy, approximately 2 minutes.
03 - Add the unsweetened cocoa powder, salt, milk, and vanilla extract to the creamed mixture. Blend on medium speed until the mixture is smooth and uniform in color.
04 - Gradually fold in the cooled, heat-treated flour, mixing on low speed until just combined. Avoid overmixing to keep the dough tender.
05 - Add the red gel food coloring and mix thoroughly until the dough is evenly tinted a vibrant red throughout with no streaks remaining.
06 - Using a silicone spatula, gently fold the mini white chocolate chips into the dough until evenly distributed.
07 - Scoop the dough into individual serving bowls or roll into bite-sized balls. Serve immediately at room temperature or chilled.
08 - Transfer any remaining dough to an airtight container and refrigerate for up to 5 days.
