Get Ready: Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper – this makes cleanup super easy!
Mix Dry: In a medium bowl, whisk together the flour, cocoa powder, baking soda, baking powder, and sea salt. Set this aside.
Cream Wet: In a large bowl, using an electric mixer, cream together the softened butter, light brown sugar, and granulated sugar. Beat for about 2 minutes until the mixture looks light and fluffy. This step is key for a great texture!
Add Color & Flavor: Beat in the egg yolks, vanilla extract, and red gel food coloring. Mix on medium speed for another 2 minutes until everything is well combined and fluffy – you want that beautiful red hue!
Combine All: Gradually add your dry ingredient mix into the wet mixture, mixing just until everything is combined. Be careful not to overmix!
Fold in Chocolate: Gently fold in the white chocolate chips until they are evenly distributed throughout the dough.
Scoop & Bake: Scoop the dough into 18 equal balls. Place them about 2 inches apart on your prepared baking sheets. Bake for 10-12 minutes. For chewier centers, lean towards 10 minutes; for crispier edges, go for 12.
Cool Down: Once baked, let the cookies cool on the baking sheets for 5 minutes. Then, carefully transfer them to a wire rack to finish cooling for another 5 minutes before you dive in. Enjoy your homemade treats!
