Preheat your oven to 350°F (175°C) and grease a 9x13 inch baking pan.
In a large bowl, mix the melted butter and sugar until well combined.
Add the eggs one at a time, mixing well after each addition.
Stir in the vanilla extract and red food coloring until fully incorporated.
In another bowl, whisk together the flour, cocoa powder, baking powder, and salt.
Gradually add the dry ingredients to the wet mixture, stirring until just combined.
Fold in the white chocolate chips for an extra touch of sweetness.
Pour the batter into the prepared baking pan and spread evenly.
Bake for 30-35 minutes or until a toothpick inserted comes out clean.
Allow to cool before cutting into squares and serving.
