Line a baking sheet with parchment paper. Arrange two shallow bowls, one with granulated sugar and the other with powdered sugar, for rolling the cookie dough balls.
02 -
In a large bowl, beat together the softened salted butter and vegetable oil until creamy. Incorporate the light brown sugar and granulated sugar, mixing until fluffy and smooth, scraping the bowl sides intermittently.
03 -
Mix in the eggs, vanilla extract, and red gel food coloring, stirring until the dough is evenly tinted a vibrant red.
04 -
In a separate bowl, whisk together the all-purpose flour, cocoa powder, baking powder, and baking soda.
05 -
Gently fold the dry mixture into the wet ingredients. Add the milk and mix until a soft, slightly sticky dough forms.
06 -
Scoop portions of dough and roll each first in granulated sugar, then in powdered sugar, pressing lightly to achieve an even coating without flattening.
07 -
Place coated dough balls on the prepared baking sheet about 2 inches apart. Bake in a preheated oven at 350°F (175°C) for 8 to 10 minutes until edges are set and centers remain soft.

Allow cookies to cool on the baking sheet for 5 minutes before transferring to a wire rack. This resting time retains soft centers and promotes crinkly tops.
