Preheat the oven: Set oven to 350°F (175°C). Line two baking sheets with parchment paper.
Mix dry ingredients: In a medium bowl, whisk flour, baking powder, baking soda, salt, dry milk powder, and cocoa powder. Set aside.
Cream butter and sugars: In a large mixing bowl, beat softened butter, brown sugar, and granulated sugar until light and fluffy (about 2–3 minutes).
Add wet ingredients: Mix in eggs, vanilla, and orange food gel until well combined.
Combine: Gradually add dry ingredients to wet ingredients, mixing until just incorporated. Don’t overmix.
Fold in chips: Stir in chocolate chips by hand to evenly distribute.
Scoop cookies: Using a cookie scoop, drop dough balls onto prepared baking sheets, leaving about 2 inches between each.
Bake: Bake for 11–13 minutes, or until edges are set and centers are still soft.
Cool and enjoy: Let cookies cool on the baking sheet for 5 minutes before transferring to a wire rack.
